If you’re running a composable commerce stack and you want a native mobile app, the composable philosophy says you should do what you’ve always done: pick the best technology for the job and build it.

That might mean a React Native app consuming your commerce APIs. Or native Swift and Kotlin apps with their own UI layer. 

Your backend is API-first, so the data is ready. Your CMS can serve content to any frontend. Your search and personalization services don’t care whether the request comes from a browser or an app. The architecture supports it.

This is technically true. It’s also where a lot of brands spend six figures and 6-12 months building something they didn’t need to build from scratch.

How Composable Commerce Enables Mobile Apps

The composable commerce model is built around a simple idea: every component in your stack is independent, connected by APIs, and replaceable. MACH architecture (Microservices, API-first, Cloud-native, Headless) makes this practical.

For mobile apps, this means your backend is already prepared. Your commerce engine exposes product, cart, checkout, and order APIs. Your CMS delivers content via API. Your search service has its own endpoints. 

In theory, a mobile app is just another client consuming these same services.

The typical approach looks like this:

• Choose a mobile framework: React Native, Flutter, or fully native Swift (iOS) and Kotlin (Android)
• Build the mobile UI from scratch, consuming the same APIs your web frontend uses
• Integrate each backend service individually (commerce, content, search, personalization, payments)
• Handle authentication, deep linking, push notifications, and app store requirements
• Ship the app and maintain it alongside your website

This is the “composable” way to do mobile apps. It follows the same philosophy that guided every other decision in your stack: decouple, choose best-in-class, build purpose-built frontends for each channel.

On paper, it’s elegant. In practice, it creates a problem that most brands underestimate.

The Real Cost of a Separate App Frontend

Building a custom native app on top of a composable backend isn’t a small project. Even with clean APIs and a well-documented architecture, you’re building an entirely new frontend that needs to replicate what your website already does.

You’re building the same experience twice

Your website already handles product browsing, search, filtering, cart management, checkout, account management, loyalty programs, and whatever else your customers use. Your mobile app needs to do all of the same things.

Yes, the backend APIs are shared, but the frontend work, the part your customers actually see and interact with, is completely new. 

Every screen, every interaction, every edge case needs to be designed, built, and tested for mobile.

A custom ecommerce app build typically costs $150,000-$500,000+ depending on complexity, with a timeline of 6-12 months. 

That’s the initial build. Maintenance adds 15-20% of the build cost annually, and year one can be higher as you stabilize the app and address issues that only surface in production.

Every feature ships twice

This is where the ongoing cost really adds up. After launch, you’re maintaining two separate frontends that need to stay in sync.

• Your web team redesigns the product page? The app team needs to match it. 
• You integrate a new reviews provider? Two implementations. 
• You update the checkout flow for a new payment method? 

Two codebases, two QA cycles, two deployments.

In practice, one frontend always falls behind. Usually it’s the app. The web team ships updates first because that’s where the traffic is, and the app plays catch-up. Feature parity becomes a permanent operational challenge, not a one-time build effort.

You need a mobile team

Building and maintaining native apps requires iOS and Android developers, or at minimum React Native/Flutter developers with mobile expertise. 

Senior mobile developers in the US command $140,000-$220,000 per year. Even a small mobile team of two developers plus QA represents a significant ongoing cost.

For brands that already have large engineering teams, absorbing this is manageable. For most DTC and mid-market ecommerce brands, it means hiring for a capability you didn’t previously need, just to deliver an experience that’s functionally identical to your website.

The composable stack gets more composable than you wanted

Here’s the irony: composable commerce is supposed to let you pick best-in-class components and assemble them into a cohesive stack. 

Adding a separate native app frontend doesn’t just add one component. It adds an entire parallel delivery channel with its own build pipeline, its own release cycle, its own testing infrastructure, and its own team.

You chose composable to gain flexibility. But a separate mobile app frontend adds rigidity: now every backend change needs to be validated against two completely different frontends. 

Every API update needs to be tested in two places. Your “composable” stack now has a hard dependency between web and mobile release cycles.

When a Custom App Build Actually Makes Sense

To be fair, there are scenarios where building a dedicated native app from scratch is the right call.

If your mobile app needs to do fundamentally different things than your website, a custom build is justified. 

Think Nike’s SNKRS app (exclusive drops, AR try-on, community features) or Starbucks (order-ahead, in-store experience, rewards integration that drives the core business model). These apps aren’t replicas of a website. They’re distinct products with distinct capabilities.

If you’re a large enterprise with dedicated mobile engineering teams already in place, the incremental cost of building on your composable APIs is lower. You have the talent, the infrastructure, and the release management processes.

If your app needs deep hardware integration (AR, camera-based features, complex offline functionality, Bluetooth device connectivity), a custom build gives you full control over the native layer.

For most ecommerce brands, though, none of these apply. The mobile app should deliver predominantly the same shopping experience as the website, with native capabilities (push notifications, App Store presence, home screen icon) layered on top.

The Simpler Path: Let Your App Follow Your Website

At Vendrux, we work with brands running composable and headless architectures, including multiple brands on Salesforce Commerce Cloud, which is built to be modular and API-driven. 

These brands have the technical capability to build custom native apps consuming their commerce APIs. They could go the full composable route.

Most of them don’t. Not because they can’t, but because they’ve done the math.

They realize it’s just more efficient, with minimal downsides, to go with this approach instead: extend the web frontend they’ve already built and invested in, and deliver it as a native iOS and Android app. 

One source of truth. One team managing one experience. The app reflects whatever the website does, automatically.

This means:

• No second frontend to build. Your website is the app experience. Every screen, every integration, every customization carries over.
• No feature parity problem. When the website updates, the app updates. There’s no lag, no catch-up cycle, no mobile team working from a backlog of web changes.
• No separate team. Your existing web team manages the experience. You don’t need to hire mobile developers to maintain a parallel codebase.
• Basic native capabilities included. Push notifications, deep linking, App Store and Google Play distribution, and native navigation and gestures work on top of your web experience.

This isn’t a compromise. It’s a recognition that for ecommerce, the mobile app and the website should deliver the same experience. And that a completely different experience for app users vs web users, 99% of the time, makes it worse for your customers. Not better.

If you’ve already built a great web frontend on your composable stack, duplicating that effort in a separate native codebase just adds overhead.

Vendrux does this for brands across the composable and headless spectrum. It works with any web frontend, regardless of what commerce engine, CMS, or search provider sits behind it. 

That’s the actual composable approach to mobile: plug in a purpose-built component for native app delivery, without rebuilding what you’ve already built.

The Composable Answer to Mobile Apps

Composable commerce is about assembling best-in-class components for each part of your stack. 

For mobile app delivery, the best-in-class approach isn’t building a second frontend from scratch. It’s extending the frontend you already have.

Your composable stack gives you flexibility in the backend. Your web frontend uses that flexibility to deliver a great customer experience. 

The simplest, fastest, and most maintainable way to bring that experience to your app is to build on what exists, not to start over.

If you’re evaluating whether to build a custom app on your composable backend, ask one question: will the app do something fundamentally different from the website? 

If the answer is no, you don’t need a separate build. You need a better delivery mechanism.

Build vs buy is one of the oldest frameworks in enterprise technology. 

The question is simple: should your company build a piece of software internally, or buy an existing solution?

The thing is, the answer looks very different depending on the use case. Build vs buy for a CRM or ERP is a lot different than for a mobile app. The latter can get complicated.

In this article, we’ll clearly explain the framework for you, plus the problem with build vs buy for mobile apps. We’ll give our recommendation for the best approach – including a solution that gives you the best of both worlds.

What “Build vs Buy” Means

Build vs buy is a decision framework for whether to develop software internally or purchase an existing solution.

A classic example would be a CRM. You could “build” your own CRM internally; every line of code built and managed in-house. Or you could “buy” access to a platform like Salesforce or HubSpot.

For mobile apps, “build” means hiring developers or an agency to create a custom app from scratch, while the “buy” path typically means using an app builder platform. 

However, the lines are blurrier than with other software categories. This means it’s hard to rely on the same build vs buy pros and cons matrix you’ve read everywhere else when it comes to launching your app.

Where the Framework Breaks Down for Mobile Apps

With a CRM, an email marketing platform, an ERP, a help desk, “buy” means you sign up, configure it, and you have a working product. 

Salesforce is a CRM. Klaviyo is an email platform. The product is fully formed. You’re buying a finished solution and adapting it to your needs.

With mobile apps, “buy” doesn’t work like that.

No app builder hands you a finished app. You buy access to a platform, then build your app inside it: choosing a template, configuring your navigation and pay layouts, connecting data sources, populating content, testing across devices, iterating on the experience. 

The platform gives you tools, but you still do the work.

The reason this is important is that many of the traditional benefits of buying don’t fully apply with mobile apps. Buying software typically means:

• Immediate time to value. You sign up, configure, and start using it within days or weeks.
• No engineering resources required. Your team uses the product; they don’t build it.
• Automatic updates. The vendor improves the product for everyone.
• Predictable, low maintenance. The vendor handles the infrastructure.

With app builders, you get some of these benefits, but not all. 

You still need time to build and configure the app. You still need someone to manage it. You’re responsible for a lot more technical maintenance (even if you’re not managing the underlying code) than if you were just installing an app or using a SaaS.

The Case for Building Your Own Ecommerce App

So – while understanding that build vs buy is not as clear cut in this arena – let’s get into the main debate.

Should you “build” your app?

Building custom gives you the most control. You define every screen, every interaction, every pixel. 

You can, objectively, ship the best possible version of your app (assuming you have the budget for it).

You’ve got:

• Full creative control over UX and design
• Ability to build features that don’t exist on the web (AR try-on, barcode scanning, complex offline workflows, hardware integration)
• Potential competitive moat if your app experience is truly differentiated
• No dependency on a third-party platform’s roadmap or limitations

Sounds perfect, right?

So what’s the downside?

The Cost of Building Your Own App

Custom ecommerce app development costs typically start around $150K, for any moderately complex ecommerce store.

It’s a project with a lot of moving parts, lasting anywhere from 6-18 months.

And when you go live, that’s not the end. You’ve got the classic downside of building vs buying: maintenance.

Building your own app can cost six figures plus per year to maintain; and that’s being relatively conservative.

“If we had unlimited time and money, we would probably go for a custom native app, but that is half a million to a million a year to maintain.”
– David Cost, VP of Ecommerce at Rainbow Shops

The integration problem

Think of all the tools running your ecommerce website.

You might have:

• Search (Algolia)
• Email and SMS (Klaviyo)
• Reviews (Yotpo, Judge.me)
• Loyalty (Smile.io, LoyaltyLion)
• Subscriptions (ReCharge)
• Personalization (Nosto, Dynamic Yield)
• Live chat (Gorgias)
• Payment processing
• Shipping
• Tax calculation
• Fraud detection.

A typical mid-market ecommerce store runs 20-40 integrations that directly touch the customer experience. Enterprise stores can run 80-100+.

When you build a custom app, you need to build a custom integration for each of these things, if you want them to work with your app like they do on your website.

A single integration takes roughly 150 engineering hours to build and 300 hours per year to maintain. At 20 integrations, that’s 3,000 hours just for the initial build, and 6,000 hours per year to keep them current.

At typical US agency rates of $100-$200/hour, the integration work alone can cost $300,000-$600,000.

The two-codebase problem

Your website changes constantly. New products, updated pricing, seasonal promotions, redesigned pages, new integrations, A/B tests. Your ecommerce team ships changes weekly, sometimes daily.

With a custom app, every one of those changes needs to be repeated in the mobile codebase. It doesn’t seem like much at first, but the dev hours – and the bandwidth – stacks up fast.

It adds a huge amount of operational complexity, which doesn’t just cost a lot, it can start dragging down other areas of your business as well.

The project risk

70% of digital transformation initiatives fail to meet their objectives, according to McKinsey. Custom app projects are no exception. 

Scope creep, integration surprises, timeline overruns, and budget blowouts are the norm, not the exception.

The question to ask: Is your mobile app experience so fundamentally different from your website that it justifies a ground-up build, with all the cost, risk, and ongoing maintenance that comes with it?

For most ecommerce brands, the honest answer is no.

The Case for Buying (App Builder Platforms)

Template-driven, no-code app builders promise a faster, cheaper alternative. 

Instead of building from scratch, you use templates, drag-and-drop tools, and pre-built connectors to get an app into the App Store faster.

There are a lot of advantages to this approach:

• Lower upfront cost ($200-$500/month typically)
• Faster time to market (weeks instead of months)
• No engineering team required for initial setup
• Pre-built templates and connectors for common use cases

But “buying” an app builder isn’t really buying in the traditional sense.

When you “buy” Salesforce, you have a working CRM by the end of the week. When you “buy” an app builder, you have access to a platform. But you still need to:

• Choose and customize templates
• Build out your navigation and page structure
• Connect your data sources and catalog
• Configure your checkout flow
• Set up push notification campaigns
• Test across devices and OS versions
• Submit to the App Store (and handle rejections)
• Keep the app updated as your website changes

You’re doing less engineering than a custom build, but you’re still building. And you take on ongoing maintenance responsibility that a true “buy” decision typically doesn’t require.

The platform limitations

This whole debate assumes there are viable “buy” options that work for you.

Most app builders are Shopify-only. If you’re on Shopify, Shopify Plus, you’re good.

But if you’re on Adobe Commerce, Salesforce Commerce Cloud, BigCommerce, or a custom platform, they simply don’t work for you.

There are some template-based app builders that work with these platforms, but not many. The complexity of an Adobe Commerce store or a SFCC site is just not a great fit for a no-code app builder.

The API problem

Even if there’s a solution that works with your web platform, there are constraints. 

Shopify’s Storefront API has limitations. You may not be able to do everything you do on your website inside the app.

The same thing applies for BigCommerce, Adobe Commerce, WooCommerce, or whichever platform you’re built on.

The integrations you use on your website all rely on custom APIs to work in your app as well.

If the app builder doesn’t support an integration you need, or if the functionality offered by the API isn’t enough, you need to ditch it, or build a custom API (and now you’re “building” not “buying”).

Plus, every API means a potential point of failure; something that can break when the vendor makes an update and unknowingly introduces a conflict with another tool or disrupts custom functionality you’ve built, putting you at risk of downtime and lost sales.

The sync problem

If you’re like most ecommerce brands, your website is your preferred source of truth. 

When you add a product, change a price, update a landing page, or launch a promotion, you do so on your website. Launching an app introduces a new channel – essentially a new storefront to update.

With most app builders, those changes don’t automatically flow to the app. Someone on your team needs to manage the app as a separate channel, keeping it in sync with the website manually.

This is the gap between “buying” an app builder and truly buying a finished solution. You’ve bought a tool, but you still own the ongoing work of building and maintaining the app inside it.

What Does Your Ecommerce Brand Actually Need?

You want a mobile app – but have you stopped to think about what that really means?

It’s not a fundamental re-imaginging of your user experience. Your mobile website already does everything you need, and a mobile app is not that much different.

It’s a product catalog, a homepage, collections, a search bar, a loyalty widget, a checkout.

App shoppers aren’t engaging in a fundamentally different way than a mobile web shopper. The differences are peripheral.

• A framework that lets customers download your store and open it from their homescreen
• Removing the browser tabs and other distractions of the mobile browser
• Native push notifications that reach customers on their lock screen
• A persistent, contained experience

Do you need to rebuild that? Do you need to “buy” a solution that operates independently from your website?

Or do you just need to extend your website into a mobile app?

The Third Path: Creating a Custom Native App (Synced with Your Site) with Vendrux

Vendrux takes a different approach to the classic build vs buy options. 

Instead of building a new app or buying a platform to build one inside, Vendrux delivers your existing mobile website as a native iOS and Android app.

Everything carries over. Product pages, collections, every integration, your checkout flow. If it works on your website, it works in the app. 

• Algolia search
• Klaviyo CRM
• ReCharge subscriptions
• Yotpo reviews
• Gorgias live chat

You’re not rebuilding integrations, or sacrificing anything.

And, crucially, your website and app are 100% in sync. There’s no maintaining a separate platform, no duplicate work.

Vendrux is the best parts of build and best parts of buy, in one.

From “build” you get:

• A real native app in the App Store (not a PWA, not a lite version of a mobile app)
• Full design and brand flexibility – because anything you can build on the web carries over to your app

From “buy” you get:

• Speed: live in the App Store in 6-8 weeks
• Cost: a fraction of custom development (both upfront and ongoing)
• A partner that handles all the the technical aspects of your app for you

It’s a different architectural approach: giving you all of what you really need in a mobile app, with none of the complexity and cost of custom builds, none of the limitations of a “buy” approach.

Comparison: Build vs Buy (vs Vendrux)

Custom development wins on one dimension: maximum flexibility. 

If you need an app that does things your website cannot do, custom is the only path. But for most ecommerce brands, the app needs to do what the website does, plus push notifications and native delivery.

App builders are the cheapest option upfront. But the lower price comes with trade-offs in platform support, integration depth, customization, and the ongoing effort of keeping the app in sync with your site. 

It works for smaller Shopify stores with straightforward needs. For mid-market and enterprise brands with complex tech stacks, the limitations become blockers.

Vendrux’s cost is higher than a basic app builder, but it’s a fully managed service, with no engineering time required, and no template constraints or integration gaps. 

When you factor in the internal team effort that app builders still require, the total cost of ownership could actually be comparable or lower.

How to Decide Which Path Is Right for Your Brand

Consider custom development if:

• Your mobile app needs to do things your website fundamentally can’t (AR try-on, complex offline workflows, hardware integration like NFC or Bluetooth)
• The mobile app is your primary product, not just a channel
• You have the budget ($500K+), timeline (12+ months), and internal resources to sustain a mobile engineering effort long-term

Consider an app builder if:

• You’re at a lower revenue stage (
• You’re on Shopify, with a relatively standard store setup
• You want your mobile app UX to deviate strongly from your mobile website
• You’re comfortable managing the app as a separate channel and handling the sync with your website

Consider extending your website (Vendrux) if:

• You want your full ecommerce experience in a native app, without rebuilding your tech stack
• You’re on any platform – particularly more complex, headless platforms (Shopify Plus, Adobe Commerce, SFCC, BigCommerce)
• You need full integration parity: every tool on your website working in the app, automatically
• You don’t want to hire mobile engineers or dedicate internal resources to app maintenance
• You want to be live in the App Store in weeks, not months

Questions to ask before committing to any approach

1. What happens to our integrations? How many of our 20-40+ customer-facing tools carry over to the app, and how much work is required to make them work?
2. What’s the real time to launch? Not the sales pitch. From signed contract to live in the App Store, what does the timeline actually look like?
3. Who maintains the app after launch? When iOS 20 drops, when we redesign our checkout, when we swap out our search provider, who does the work?
4. Does the app stay in sync with our website? If we launch a promotion at 9 AM, is it live in the app at 9 AM? Or does someone need to update the app separately?
5. What’s our total cost of ownership over three years? Not just the subscription or build cost. Internal team time, integration work, ongoing maintenance, opportunity cost.

The Build vs Buy Framework: In Summary

Build vs buy is a good starting point any time you think about adding functionality to your business. It forces you to think about cost, control, speed, and strategic value.

When we’re talking about ecommerce mobile apps, we’re talking about a lot more than “functionality”. We’re talking about a whole new channel for your business.

That’s why build vs buy doesn’t always cover the whole picture.

Most ecommerce brands don’t need to build a new user experience from the ground up. They just need to extend the one they’ve already invested in. 

A native app powered by the website you’ve spent years perfecting, with push notifications to drive retention, home screen presence to stay top of mind, is all you really need; and understanding this will help you pick the option with the best long-term ROI.

If that sounds like what your brand needs, book a quick strategy call. We’ll talk through your website, your tech stack, and help you figure out whether extending makes sense for your situation. No pressure, no commitment.

Most ecommerce brands today sell through multiple channels: a website, a mobile app, email, social commerce, maybe even physical retail. 

But being present on multiple channels and actually connecting those channels are two very different things.

These terms can be wishy-washy, they can be confusing. But the distinction is important to understand, if you really want to optimize your ecommerce experience for the way consumers buy today.

This guide breaks down what each strategy actually means, how they differ in practice, and how to evaluate your brand’s approach.

What Is Multichannel Ecommerce?

Multichannel ecommerce is a strategy where a brand sells products through more than one channel. 

These channels typically include a website, a mobile app, social media storefronts, email campaigns, marketplaces like Amazon, and sometimes physical stores.

The defining characteristic of multichannel is that each channel operates independently. 

• The website team manages the website.
• A separate agency or team builds the mobile app.
• Email marketing runs on its own platform with its own customer data.
• The marketplace listing has its own inventory feed.

Multichannel is channel-focused: the goal is to be present wherever customers are shopping. Each channel has its own goals, its own metrics, and often its own version of the customer experience.

Multichannel Ecommerce Example

A Shopify brand sells through their website, has a separate mobile app built by a development agency, runs email campaigns through Klaviyo, and lists products on Amazon. A customer who adds an item to their cart on the website won’t see it in the app. A loyalty discount earned in-store doesn’t apply online. Each channel works, but they don’t work together.

What Is Omnichannel Ecommerce?

Omnichannel ecommerce is a strategy where all of a brand’s sales channels are integrated into a single, unified customer experience. 

The customer can start shopping on one channel, continue on another, and complete their purchase on a third without losing context, data, or functionality.

The defining characteristic of omnichannel is that it’s customer-centric rather than channel-centric. Instead of optimizing each channel independently, omnichannel brands optimize the overall customer journey across all touchpoints.

Brands often cited as omnichannel leaders include Nike (unified app, website, and retail experience), Starbucks (loyalty rewards that work identically across app, web, and in-store), and Target (seamless BOPIS and same-day delivery tied to their app).

Omnichannel Ecommerce Example

A customer browses products on a brand’s mobile app during their commute, adds items to their cart, then opens the website on their laptop at home and finds the same cart waiting. They use a discount code from an email campaign, choose buy-online-pick-up-in-store (BOPIS), and receive a push notification when the order is ready. After pickup, they get a follow-up email with personalized recommendations based on their full purchase history across all channels.

What’s the Difference Between Omnichannel and Multichannel?

All omnichannel strategies are multichannel, but not all multichannel strategies are omnichannel.

The key difference is integration.

Channel Integration vs Channel Presence

Multichannel is about presence: being on multiple platforms. Omnichannel is about integration: making those platforms work as one system. 

A brand with a website, an app, and an email list is multichannel. A brand where those three channels share customer data, cart state, and promotions in real time is omnichannel.

Customer Data: Unified vs Siloed

In a multichannel setup, your email platform knows what campaigns a customer clicked. Your website knows their browsing history. Your app knows their push notification preferences. But none of these systems share that information with each other.

In an omnichannel setup, every interaction feeds into a single customer profile, often managed through a customer data platform (CDP). This means your email campaigns can reference in-app behavior, your app can surface products the customer browsed on the website, and your support team can see the full customer history regardless of which channel the customer used.

Experience Consistency Across Touchpoints

73% of retail shoppers engage across multiple channels during their buying journey. In a multichannel setup, each transition is a potential friction point: pricing may differ, promotions may not carry over, and the customer may need to re-enter information.

In an omnichannel setup, the brand looks, feels, and functions the same everywhere. Product pages have the same information. Checkout flows work the same way. Loyalty points earned on one channel are immediately available on every other channel.

Why Does Omnichannel Outperform Multichannel?

The performance gap between multichannel and omnichannel brands is well documented.

For a brand doing $10M+ in annual revenue, closing even part of this gap could mean hundreds of thousands in additional revenue, driven not by acquiring new customers but by serving existing ones better across every touchpoint.

What Are the Challenges of Implementing Omnichannel Ecommerce?

Omnichannel sounds straightforward in theory. In practice, 64% of ecommerce marketers cite the need for more resources and investment as the top barrier to implementation.

Tech Stack Fragmentation

The most common barrier is technology. Many brands end up with what amounts to a fragmented stack: 

• Their website runs on Shopify or BigCommerce
• Their app was built by a separate agency
• Their email and SMS run through Klaviyo or Omnisend
• Their loyalty program lives in another system
• Their POS handles in-store transactions

Each tool may be excellent on its own, but getting them to share data and deliver consistent experiences requires middleware, custom integrations, and ongoing maintenance. 

The irony: brands invest in multiple channels to reach customers everywhere, then spend just as much trying to make those channels talk to each other.

Maintaining Consistency Across Channels

When your website and app are separate codebases maintained by different teams, they inevitably drift apart. 

A promotion goes live on the website but hasn’t been updated in the app. Product descriptions differ. The checkout flow works slightly differently.

Every inconsistency is a seam your customers can feel, and every seam is a potential drop-off point.

Organizational Silos

Technology is only part of the problem. When different teams own different channels with separate KPIs, they optimize for their channel rather than the overall customer experience. 

The email team maximizes opens and clicks; the app team maximizes downloads and sessions; the web team maximizes conversion rate. Nobody owns the cross-channel journey.

How to Build an Omnichannel Ecommerce Strategy

You don’t need to overhaul everything at once. The most effective path is to reduce the number of systems powering your customer experience, so channels become different views into the same store rather than separate projects.

The Shared Infrastructure Approach

The brands that get omnichannel right tend to share one principle: every channel should be an extension of the same core experience, not a separate product with its own roadmap and codebase.

Consider what happens when your mobile app is built on top of your existing website rather than from scratch. Same product data. Same checkout. Same promotions. Same loyalty program. 

The app becomes a native delivery mechanism for an experience you’re already maintaining, not a separate product that drifts further from your website with every update.

This is the approach that scales. Not more channels running independently, but fewer systems powering a consistent experience across every touchpoint.

Omnichannel Consistency Audit: 6 Questions to Ask

Before investing in new channels or technology, audit what you have. Every “no” below is a gap in your omnichannel experience:

1. Cart continuity: If a customer adds items on one device, do they appear on another? Test this from website to app and back.
2. Promotion parity: Are current sales, discount codes, and loyalty offers identical across every channel?
3. Account unity: Does a customer have one account that works everywhere, or separate logins for website, app, and loyalty program?
4. Communication coordination: Do push notifications, email, and SMS complement each other, or overlap? Would a customer feel spammed?
5. Support continuity: Can a support agent see a customer’s full order history across all channels without asking?
6. Content consistency: Open the same product page on your website and app side by side. Same images, descriptions, reviews, and price?

How Do Mobile Apps Fit Into an Omnichannel Strategy?

For most ecommerce brands, the mobile app is the channel with the highest omnichannel potential and the highest fragmentation risk.

Mobile commerce accounts for a growing majority of ecommerce traffic. And most mobile shoppers find it more convenient to shop in an app.

A native app offers push notifications, home screen presence, and faster performance, all of which drive the repeat engagement that omnichannel depends on. 

But when your app is built as a separate product from the website, it becomes another silo to maintain, another source of inconsistency.

This is exactly why, at Vendrux, we take the approach of extending your existing website into a native iOS and Android app. 

Instead of rebuilding your store as a separate mobile product, Vendrux delivers your full website experience as a native app. Same product catalog, same checkout, same promotions, same everything. 

Your app and website stay in sync automatically because they share the same infrastructure.

The result is true omnichannel consistency between your two most important digital channels, without the integration overhead that usually makes it so difficult.

Search users convert at 2-3x the rate of browsers, and they account for a disproportionate share of your revenue. So when you launch a mobile app, you need to ensure your search function fully carries over to your app.

The problem? Depending on how you build your app, you’ll likely face one of the following challenges:

• Your site search doesn’t work the same way in your app
• Your site search doesn’t work at all in your app
• Your site search works – but it costs a fortune to build the integration (and is at constant risk of breaking)

This is not a small feature. This is the core of your buyer journey.

Keep reading to learn why this is such a tricky integration, and how to ensure your ecommerce site search actually works when you launch a mobile app.

Site Search Is Probably Your Most Valuable Integration

This isn’t hyperbole. Site search might be the most important feature of your store.

Constructor analyzed 609 million searches across 113 retail sites in Q4 2024 and found that while searchers represent roughly 15-25% of traffic, they generate close to half of total revenue. 

In some verticals, the numbers are even more lopsided:

• Health & Beauty: Searchers are 25% of traffic but drive 57% of revenue, converting at 17% vs 6% for non-searchers
• General Merchandise: 41% of traffic, 61% of revenue
• Specialty & Hobby: 26% of traffic, 49% of revenue

Search is a core part of how your customers find and buy products. And if you give them a good experience, the numbers prove that they’re more likely to buy, and will spend more.

If it’s this effective on your website, it stands to reason that you want this feature working in your mobile app too.

How Your Search Tool Actually Works

To understand why search often breaks in mobile apps, it helps to understand how it works on your site in the first place.

Enterprise search tools like Algolia, Searchspring, and Constructor don’t live inside your ecommerce platform. They sit on top of it. 

Here’s what typically happens:

1. A JavaScript SDK loads on your pages. When a customer visits your site, the search provider’s JavaScript runs in the browser. It powers the search bar, autocomplete suggestions, and results pages.
2. The SDK calls the search provider’s API directly. When someone types a query, the request goes to Algolia’s servers or Searchspring’s servers, not to Shopify or your ecommerce platform. That’s what makes it fast and relevant.
3. Custom UI components render the results. The search overlay, the faceted filters, the merchandised results, the “did you mean” suggestions, all of it is rendered by the provider’s frontend code on your website.
4. Merchandising rules run server-side. Your team has configured boost rules, pinned products, and category-specific sorting. Those rules live in the search provider’s dashboard and get applied to every query.

The key detail: all of this runs as JavaScript on your rendered web pages. 

Your ecommerce platform provides the product data. The search tool handles everything the customer actually sees and interacts with.

This matters because of what comes next.

Why No-Code App Builders Break Your Search

Most no-code mobile app builders for Shopify (and to a lesser extent BigCommerce and other platforms) work by rebuilding your storefront from scratch. 

They use the platform’s APIs, like Shopify’s Storefront API, to pull product data, and then render a new mobile-native interface.

That new interface is built by the app builder. It’s their code, their templates, their UI components. Your website’s JavaScript never runs, because your website is never loaded. The app builder has constructed an entirely different frontend.

Here’s what that means for your search feature:

Your search tool’s JavaScript SDK doesn’t execute

There’s no browser loading your website, so there’s no JavaScript environment for Algolia or Searchspring to run in.

The app builder falls back to native platform search

Instead of your tuned, AI-powered search with merchandising rules and personalized results, customers get whatever basic search the platform API provides. 

For Shopify, that means the Storefront API’s built-in search, which offers a fixed set of predefined sort keys and none of your custom ranking logic.

All your merchandising rules disappear

The boost rules, pinned products, synonym mappings, and category-specific configurations you’ve built in your search provider’s dashboard? They don’t apply. The app builder’s search interface doesn’t know they exist.

Autocomplete and faceted filtering degrade

Some app builders offer their own version of filters and search suggestions, but they’re generic. They don’t reflect the custom facets, filter groups, and autocomplete behavior your search provider delivers.

Dedicated integrations with search tools

Some app builders do offer integrations with popular search tools. But integration support varies by plan (often requiring enterprise tiers), the implementation may not match what you have on web, and less common search providers may not be supported at all. If you’re running Constructor or Bloomreach, for example, your options are limited.

The result of all this is that your app’s search experience is likely to be worse than your website’s. And since searchers are your highest-intent, highest-converting visitors, that’s a meaningful revenue hit.

“Our app needs to be at least as functional as the website. It doesn’t need to be better than the website, but the user experience can’t be worse.”
— David Cost, VP of Ecommerce at Rainbow Shops

The Cost of Integrating Your Search in a Custom Mobile App

The alternative is building a fully custom mobile app. Build it from the ground up, integrate everything exactly how you want it.

This gives you the ability to build a custom integration for your search function, and build it in your app to work just as it does on your website.

It works – but it also takes a long time and costs a lot.

Rebuilding a single integration like search in a custom mobile app typically takes around 150 engineering hours, plus about 300 hours per year to maintain. At typical agency rates, that’s $15,000-$30,000 just for search, before you account for the ongoing maintenance.

And there’s an ongoing problem: every time your search provider ships an update, changes their API, or adds a new feature, your mobile app needs a corresponding update. 

That adds a lot of work, a lot of new development sprints.

It’s also another integration that can break, another potential point of failure. Another thing making your tech stack more complicated.

How to Ensure Your Site Search Works in Your Mobile App (Without the Double Work)

The reason search breaks in most app approaches is that your mobile app is a completely separate storefront.

Even with headless builds, your app and website are two distinct channels. That means UX features like site search operate differently on each one.

Vendrux takes a different approach. Instead of rebuilding your storefront, Vendrux extends your existing website into a native iOS and Android app. 

Your actual website powers the app, which means every JavaScript-based integration that works on your site works in the app, automatically.

For your search function, that means:

• Your Algolia, Searchspring, Constructor, Klevu, or Bloomreach integration works as-is. The JavaScript SDK loads. The API calls fire. The results render exactly as they do on your website.
• Merchandising rules, personalization, and faceted filtering carry over. Because the search provider’s code is actually running, all your configured rules apply.
• When you update search on your website, it updates in the app. Add a new synonym mapping? Change your boost rules? Redesign the search results page? It’s live in the app the next time a customer opens it.
• No integration cost, no integration timeline. There’s nothing to rebuild, because there’s nothing missing.

This isn’t limited to search. It applies to every tool running on your website: reviews, loyalty programs, personalization engines, subscription management, live chat, A/B testing, analytics. 

If it works on your site, it works in the app.

On top of that, you get actual native app capabilities: push notifications with deep linking, native navigation, app store presence, and a home screen icon. 

Your customers get the full shopping experience they’re used to on your website, delivered through a native app that sits next to Amazon and TikTok on their home screen.

What This Means for Your Search Investment

If you’ve put time and money into getting site search right, you should be protective of it when evaluating mobile app options. Here’s a simple framework:

Ask your app builder (or development agency) these questions:

1. Does my specific search provider (by name, not “we support search”) work in the app?
2. Do all my merchandising rules, boost logic, and personalization carry over?
3. When I make changes to search on my website, what’s the process for updating the app?
4. What does the search experience look like for customers who use the app vs the website? Can you show me a side-by-side?

If the answers involve “we have our own search” or “we’d need to build that integration” or “that would require our enterprise plan,” you’re looking at either a degraded experience or a significant additional investment.

The simplest way to keep your search working is to keep your website working, and deliver it as a native app.

Subscriptions are the hottest way to build an ecommerce business today – and for good reason.

Subscription customers generate 3-5x more lifetime revenue than one-time buyers, and the 30% of subscribers who stick around long-term account for roughly 80% of subscription revenue. 

Every piece of your subscription experience, from the product page widget to the self-service portal, exists to keep those customers enrolled.

• Your cancel flows have been A/B tested.
• The customer portal lets subscribers skip, swap, and pause without emailing support. 
• The build-a-box feature drives higher AOV every cycle. 

Whether you’re on Recharge, Skio, Loop, Stay AI, Smartrr, or something else, the subscription layer on your website is doing serious work.

Then the conversation about building a mobile app starts. And what you don’t realize is that your customer portal, cancel flows, build-a-box customization, payment update screens, and all the other features that make your subscription system tick over may not work in your mobile app (depending on how you build it).

But all these features have to be a part of your app. It’s not worth launching the app in the first place if they’re not.

So what’s the solution? Spend hundreds of thousands on a delicately constructed, custom native app?

Luckily no. Keep reading and we’ll explain everything.

Why Subscriptions and Mobile Apps Are a Natural Fit

Before getting into the technical problem, it’s worth understanding why subscription brands and mobile apps work so well together. The connection goes beyond general ecommerce benefits.

Your subscribers are already your most engaged customers

Subscription customers have already committed to your brand on a recurring basis. They’re exactly the kind of customer who downloads an app. 

They’re checking order status, managing upcoming deliveries, browsing new products to add to their next order. An app gives them a faster, more convenient way to do all of that.

The numbers back this up. Vendrux customers consistently see 3-5x higher revenue per app user compared to mobile web. For subscription brands where repeat engagement is the entire business model, that lift compounds over time.

Push notifications solve subscription-specific problems

Subscription brands have communication needs that email handles poorly:

• “Your payment failed.” This is the leading cause of involuntary churn. If a customer misses the email (and most do, with ~20% open rates), they churn without ever deciding to leave. A push notification lands directly on their lock screen.
• “Your next order ships in 3 days. Want to swap anything?” Time-sensitive, high-value. The customer who sees this adds a product or adjusts their box. The customer who doesn’t see it gets an order they didn’t really want, and that’s how voluntary churn starts.
• “You’ve earned a free product.” Loyalty and gamification features from tools like Loop and Smartrr only work if subscribers actually know about their rewards.

And unlike SMS, push notifications cost nothing to send. For a subscription brand sending multiple touchpoints per billing cycle, that adds up.

The home screen is a churn-reduction tool

A subscription brand’s biggest enemy isn’t a competitor. It’s indifference. 

When your brand occupies a home screen icon next to Amazon and Instagram, you stay top-of-mind between orders. That matters, because 27% of subscribers say they’d cancel if they couldn’t easily skip or pause, and an app makes those actions feel effortless instead of buried.

How Subscription Tools Actually Work on Your Website

To understand why subscriptions break in mobile apps, you need to understand what’s running on your site in the first place.

Modern subscription platforms aren’t simple checkout add-ons. They’re multi-layered systems with at least three distinct components, each with its own technical implementation.

The subscription widget (product pages)

When a customer visits a product page, they see the option to choose between a one-time purchase and a subscription. This widget shows frequency options, discount tiers, and delivery schedules.

On Shopify, this works through the Selling Plan API. The subscription app creates selling plans that define pricing and billing policies, then renders a theme app block on the product page. 

The customer selects their preference, and Shopify’s checkout handles the rest via Checkout Extensions.

Some platforms still use a JavaScript widget approach, where the subscription app’s SDK loads on the page and watches for variant or price changes to update the subscription options in real time.

The customer portal (subscription management)

This is where subscribers go to manage their active subscriptions: skip a delivery, swap a product, change frequency, update payment info, or cancel.

There are three common implementations:

1. Hosted portal. The subscription app runs the portal on its own domain. Customers click a link and get redirected. Simple to set up, but the customer leaves your site.
2. Embedded portal. The hosted portal loads inside an iframe on your website. Customers stay on your domain, but the portal content comes from the subscription app’s servers.
3. Custom portal. Built by your development team using the subscription app’s API. Full control over branding and UX. Significant build and maintenance cost.

Each approach involves authentication, session management, and real-time data from the subscription platform. 

• Skio’s passwordless login sends a 4-digit code via email and SMS rather than requiring a traditional password. 
• Loop’s gamified subscriber journeys show progress toward milestones and rewards. 
• Stay AI’s cancel flows use machine learning to personalize the retention offer based on subscriber behavior.

These aren’t simple features to recreate with an API call. They’re the result of months of product development by the subscription platform, rendered as a complete web experience.

The checkout flow

When a subscriber places their initial order, Shopify creates a Subscription Contract, the formal agreement for recurring billing. The customer’s payment method gets vaulted (stored with permission), and the subscription app handles all future billing attempts through Shopify’s APIs.

This entire flow runs through Shopify’s native checkout, enhanced by Checkout Extensions from the subscription app.

Why Many App Builders Break Your Subscription Experience

Most no-code mobile app builders for Shopify work by rebuilding your storefront from scratch. They pull product data through Shopify’s APIs, mainly the Storefront API, and render their own native mobile interface.

That new interface is the app builder’s code, their templates, their UI components. Your website never loads. And that means every tool running on your website needs to be separately rebuilt within the app.

For subscriptions, this creates problems at every layer.

The subscription widget may or may not work

If your app builder has built a dedicated integration with your specific subscription platform, the basic product-page widget might function. Customers might be able to select “subscribe & save” and choose a frequency.

But integration support varies. Tapcart offers a Recharge integration, for example, but it requires Recharge Pro and Tapcart Enterprise plans. If you’re on a smaller subscription tool, your app builder may not support it at all.

The customer portal is the biggest gap

This is where the real damage happens. The self-service portal, where subscribers skip, swap, pause, update payment, and manage their subscription, is typically the hardest piece to replicate in a native app.

The app builder has two options:

1. Rebuild portal functionality natively. This means the app builder needs to integrate with the subscription platform’s API to recreate every portal feature: skip, swap, pause, cancel flows, payment updates, build-a-box, gamification, loyalty rewards. Most don’t go that deep. You get basic “view subscriptions” and “cancel” functionality. The advanced features your web portal offers? Gone.
2. Open the web portal in a browser view inside the app. The customer taps “manage subscription” and gets kicked into a mobile browser window showing your web portal. The experience feels disjointed, the styling may not match the app, and authentication can break (the customer may need to log in again inside the browser view).

Neither option gives your subscribers the experience they get on your website.

Advanced features don’t translate

The subscription features that actually reduce churn and drive AOV are precisely the ones that break.

Most app builders don’t build a 1:1 integration that works exactly as it does in the app as on the web. And they’re certainly going to be a little behind when it comes to integrating new features that come out from your subscription app.

Switching subscription platforms becomes a bigger problem

If you switch from Recharge to Skio (or to any other platform), your website updates reflect immediately. Swap the app, configure the new portal, and customers see the new experience.

With an API-based app builder, switching subscription platforms means the app builder also needs to support your new tool. 

If they don’t, you’re stuck with broken subscription management in your app until they build the integration, if they ever do.

And even if the tool is supported, it means a significant update is needed for your mobile app, which adds a lot of staff hours and complexity.

Custom App Development Has the Same Problem, at Higher Cost

A custom-built mobile app can theoretically integrate with any subscription platform. You have full control over the code.

But “can integrate” and “will integrate well” are different things. Rebuilding a subscription portal in a custom app means:

• Building API integrations with your subscription platform’s backend
• Recreating the customer portal UI (skip, swap, pause, cancel, payment update, build-a-box, etc.)
• Handling authentication flows (including passwordless options if your portal offers them)
• Maintaining parity as the subscription platform ships updates and new features

At typical agency rates, rebuilding a complex integration like a subscription portal runs $15,000-$30,000, with ongoing maintenance of roughly 300 hours per year. And that’s one integration. Your site likely runs 20+ customer-facing tools.

Every time your subscription platform ships a new feature, like Loop adding a new gamification mechanic or Stay AI improving their cancel flow algorithm, your custom app needs a corresponding development sprint.

That gets expensive.

How to Keep Your Subscription Experience Intact

The reason subscriptions break in most app approaches is that they don’t run your website. They rebuild the frontend, which means every third-party tool that renders on your site needs to be separately integrated.

Vendrux takes a different approach. Instead of rebuilding your storefront, Vendrux extends your existing website into native iOS and Android apps. 

Your website powers the app, so every subscription feature that works on your site works in the app, automatically.

For subscription brands, this means:

• Your Recharge, Skio, Loop, Stay AI, Smartrr, or Bold portal works as-is. The JavaScript loads. The portal renders. The authentication flows function. The full self-service experience carries over.
• Build-a-box, gamified journeys, loyalty rewards, AI cancel flows all carry over. Because the subscription platform’s code is actually running, every advanced feature works exactly as it does on your website.
• When your subscription platform ships an update, it’s live in the app. New gamification milestone? Updated cancel flow? Redesigned portal? It appears in the app the next time a customer opens it.
• If you switch subscription platforms, the app doesn’t need changes. Move from Recharge to Skio? The app just renders whatever’s on your website. No integration to rebuild, no app builder compatibility to verify.

“We wanted everything to reflect on the mobile app. We have a lot of features and a lot of apps right now installed on our website, and all of them are reflecting seamlessly to the mobile app as well.”
— Zawar Kamal, CEO, NumberC

This approach isn’t limited to subscriptions. It works for every tool on your site: reviews, loyalty programs, site search, personalization engines, quiz funnels, live chat. If it works on your website, it works in the app.

On top of that, you get native app capabilities that directly benefit subscription businesses: push notifications with deep linking (tap a “your payment failed” notification and land directly on the payment update screen), a home screen icon that keeps your brand visible between orders, and the performance and engagement benefits that come with a dedicated app experience.

All this, while you just manage one platform: your website. Your app stays in sync automatically.

“It’s great to have an app, but realistically, you can’t really be managing your website and your app separately.”
— Patrick Levesque, Co-Founder, MASC

Questions to Ask Before You Build

If you’re evaluating mobile app options for your subscription brand, here’s what to ask:

1. Does my specific subscription platform work in the app? Not “we support subscriptions” in general. Does Skio’s passwordless portal work? Does Loop’s gamification render? Does Stay AI’s cancel flow function?
2. What happens to the customer portal? Can subscribers skip, swap, pause, update payment, and manage build-a-box in the app, with the same experience they get on the website?
3. What plan do I need for subscription support? Some app builders gate subscription integrations behind enterprise-tier pricing. You could launch an app for $100 a month, but not with all the features you need. Find out before you commit.
4. What happens when I update my subscription setup? If you change subscription platforms, redesign your portal, or add new features, does the app update automatically or does it require a separate build?
5. Can you show me a side-by-side? The subscription portal on the website vs. in the app. If they look and function differently, your subscribers will notice.

If the answers involve “we’d need to build that” or “that feature isn’t supported yet” or “you’d need our enterprise plan,” you’re looking at either a degraded experience or a bigger project than anticipated.

The simplest way to keep your subscription experience working is to keep your website working, and deliver it as a native app.
