Ecommerce Mobile App Development Cost: How Much to Build an App in 2026?

A mobile app can be one of the best investments you make as an ecommerce brand. But, like any investment, it depends significantly on how much you pay.

Ecommerce mobile apps, as with any mobile apps, can come at a steep price. You could be looking at a price of $250,000 or more, along with recurring maintenance costs that add another $100K+ per year, just to keep it running.

However, the cost can also be a lot more affordable, with more efficient development approaches that deliver an app that’s just about on the same level as what you’d get with a full custom build.

We’ve been building mobile apps since 2013, successfully launching over 2,000 mobile apps. So we’ve got a lot of experience in the industry, and are acutely aware of the real costs you can expect.

In this article, we’ll break it all down; from the estimated cost of custom ecommerce mobile app development, to the additional costs you need to budget for, how to cut down dev costs by hiring more affordable developers, and alternative app development approaches that flip the cost structure on its head.

Short Answer: How Much Does It Cost to Build an Ecommerce Mobile App?

Realistically, you could be looking at anywhere from $30,000 to $250,000 or more to build an ecommerce app.

It’s a little bit like asking “how long is a piece of string”. The cost can vary greatly, depending on who you hire, how complicated your app needs to be, and how smoothly the project goes.

There’s a big difference between a simple catalog app for a small retail store, and a multi-storefront app for a global fashion brand with AR try-on built in.

There’s also a big difference between hiring the best mobile app developers in Silicon Valley and hiring a boutique dev agency from South Asia.

What Determines Ecommerce App Development Cost

So we’ve got a (very) rough ballpark figure. But to help you understand the cost of building an ecommerce app better, let’s take a look at what contributes to the cost, and how the cost can vary by features, hiring approach, and more.

App complexity and feature scope

This is the single biggest cost driver. A basic ecommerce app with product listings, a shopping cart, and payment processing is a fundamentally different project than a multi-vendor marketplace with AI-powered recommendations and AR product previews.

Each additional feature adds development time and, in custom builds, ongoing maintenance burden. Features like real-time inventory sync, multi-currency support, and advanced search filtering can each add $2,000 to $15,000 to a custom build.

Platform choice: iOS, Android, or both

Building natively for iOS and Android means two separate codebases, two development teams, and roughly double the cost. 

Cross-platform frameworks like React Native and Flutter reduce this premium to about 30-40% above a single-platform build, but still require platform-specific testing and optimization.

Almost all ecommerce apps will want to support both platforms - so limiting yourself to just an iOS or Android version is likely not an option.

Development approach

Your technical approach has a major impact on cost:

• Native development (Swift for iOS, Kotlin for Android): Highest performance, highest cost. Two codebases.
• Cross-platform frameworks (React Native, Flutter): Single codebase, slightly lower cost. Good performance for most ecommerce use cases.
• No-code tools and services: You can save a huge amount of money by NOT building a custom native (or cross-platform app), and using a no-code approach instead.

Team type and location

Who builds your app matters as much as what they build.

Developer rates vary dramatically by geography:

Sources: Accelerance Global Software Outsourcing Rates, Clutch Developer Survey 2025

These rates explain why cost estimates vary so widely. A mid-level ecommerce app built by a US agency might cost $120,000, while a similar spec built by an Indian team could come in at $30,000-$40,000. 

There are tradeoffs, of course, to paying lower rates. While you could get a result that’s just as good from cheaper offshore developers, there is usually some correlation between cost and quality.

Ecommerce App Development Cost by Complexity

Here's what custom development typically costs at each tier, based on aggregated estimates from various ecommerce mobile app development agencies, and our own industry research.

Basic ecommerce app ($15,000-$40,000)

Timeline: 3-6 months

A basic app covers the essentials: product catalog, search, shopping cart, a single payment gateway, user registration, and push notifications. Think of a simple storefront with a clean checkout flow.

Typical feature set:

• Product pages with images and descriptions
• Basic search and category navigation
• Shopping cart and checkout
• One payment gateway (Stripe or PayPal)
• User accounts and order history
• Push notifications
• Basic analytics

Who this is for: Startups testing mobile commerce, or brands with a very narrow product catalog and simple requirements.

Mid-level ecommerce app ($40,000-$100,000)

Timeline: 6-9 months

This is where most serious ecommerce apps land. You get everything from the basic tier, plus advanced search with filters, multiple payment options, product reviews, order tracking, multi-language or multi-currency support, and an admin panel for managing content and inventory.

Typical additions over basic:

• Advanced search with filters and sorting
• Multiple payment gateways
• Product reviews and ratings
• Real-time order tracking
• Multi-language/multi-currency
• Wishlist and favorites
• Admin dashboard
• Social login (Apple, Google, Facebook)
• Third-party integrations (loyalty programs, email platforms)

Advanced ecommerce app ($100,000-$250,000+)

Timeline: 9-15 months

Enterprise-grade apps with AI-powered personalization, AR product visualization, sophisticated analytics, multi-vendor marketplace functionality, or deep integrations with ERP and inventory management systems.

Typical additions over mid-level:

• AI-driven product recommendations
• AR try-on or product preview
• Chatbot or live chat integration
• Multi-vendor/marketplace architecture
• Advanced analytics and A/B testing
• Custom loyalty and rewards engine
• Omnichannel inventory management
• Complex third-party integrations (ERP, PIM, OMS)

Marketplace or social commerce platform ($150,000-$500,000+)

Timeline: 12-18+ months

If you're building a marketplace (multiple sellers, separate dashboards, transaction processing, dispute resolution) or a social commerce platform (user-generated content, live shopping, community features), you're in a different category entirely.

This isn't a standard ecommerce app project. It's a software product build.

Ecommerce App Development Cost by Region

The same app, built to the same spec, costs dramatically different amounts depending on where your development team is based. Here's what a mid-level ecommerce app ($40,000-$100,000 at US rates) would cost by region:

These are estimates for a cross-platform (React Native or Flutter) build including design, development, QA, and deployment. Native iOS + Android development would typically add 40-60% to each figure.

A note on quality: Cheaper doesn't always mean worse, and expensive doesn't guarantee quality. But lower-cost regions often require more project management overhead, more detailed specifications upfront, and more rigorous QA. Factor that management cost into your estimates.

Full Cost Breakdown by Development Phase

Custom ecommerce app development isn't a single line item. Here's where the money actually goes:

Discovery and planning ($3,000-$15,000)

Before a line of code gets written, you need requirements documentation, technical architecture, wireframes, and a project plan. Skipping this phase is how $50,000 projects become $150,000 projects.

• Requirements gathering and documentation
• Technical feasibility analysis
• Architecture design
• Project planning and timeline

UI/UX design ($5,000-$30,000)

Your app's interface and user experience. This includes wireframes, visual design, prototyping, and user testing. Ecommerce apps demand a higher bar here because any friction in the shopping or checkout flow directly costs you revenue.

• Wireframes and user flows
• Visual design (brand-consistent)
• Interactive prototypes
• Usability testing

Frontend development ($15,000-$80,000)

Building the user-facing app. This is typically the largest single cost in the project, covering everything the customer sees and interacts with.

• Product catalog and browsing experience
• Search, filtering, and navigation
• Shopping cart and checkout flow
• User accounts and profiles
• Push notification handling

Backend development ($10,000-$60,000)

The server-side infrastructure: APIs, databases, authentication, payment processing, order management. If you already have a backend (your ecommerce platform), this cost drops significantly because you're integrating with existing systems rather than building from scratch.

• API development
• Database architecture
• Authentication and security
• Payment gateway integration
• Order and inventory management
• Third-party service integrations

Quality assurance and testing ($5,000-$25,000)

Testing across devices, operating systems, payment flows, edge cases, and performance under load. This is often the first thing teams cut when budgets get tight, and almost always the most expensive mistake.

• Functional testing across devices
• Performance and load testing
• Security testing
• Payment flow testing
• Regression testing

Deployment and launch ($2,000-$8,000)

App store submission, screenshots, descriptions, and navigating Apple's and Google's review processes. Apple's review process is notoriously unpredictable. Budget time for at least one rejection and resubmission cycle.

• App Store and Google Play submission
• Store listing optimization (ASO)
• Launch monitoring

Total: custom build cost summary

Cost Breakdown by Feature

At the end of the day, the cost of an app really comes down to a sum of the cost of its individual parts.

The more features, and the more complex features the more dev hours it takes and the higher the cost.

If you're scoping a custom build, here's what individual features typically cost to develop, based on estimates from around the industry:

These are development costs only, not including design, testing, or ongoing maintenance for each feature.

The Hidden Costs Most Estimates Leave Out

The build is the visible cost, the cost that gets quoted to you upfront. But there are more costs to consider, particularly the recurring costs that add up over time.

Ongoing maintenance ($6,000-$50,000+/year)

Industry standard is 15-20% of the initial development cost per year, covering bug fixes, OS updates, security patches, and minor improvements. For a $100,000 app, that's $15,000-$20,000 annually, at minimum.

Hosting and infrastructure ($2,000-$15,000/year)

Cloud hosting (AWS, Google Cloud, Azure), CDN, database hosting, and API costs. Traffic spikes during sales events can increase these costs dramatically if your infrastructure isn't properly scaled.

Third-party services ($3,000-$15,000/year)

Payment processing fees, push notification services, analytics platforms, search services (Algolia, Elastic), email/SMS APIs, and any other SaaS integrations your app depends on. These are recurring costs that compound as your user base grows.

App store fees ($124/year)

Apple charges $99/year for a developer account; Google charges a one-time $25 fee. These costs are fairly negligible, but they do exist.

Both app stores also take commissions on in-app purchases, however these generally don’t apply for ecommerce apps.

Feature updates and iterations ($5,000-$30,000/year)

Your app isn't done when it launches. Users expect new features, your competitors are evolving, and your ecommerce platform keeps updating. Budget for at least 2-4 significant feature updates per year.

3-Year Total Cost of Ownership: Custom Build vs Web-to-App

When you launch an app, it’s never a one-time cost.

You’re not building the app for a short time, or a single event. You’re launching it to be a long-term retention tool.

And it costs to keep an app running. There’s regular maintenance, infrastructure costs, feature updates.

That’s why you need to look at the total cost of ownership over a wider time horizon - such as a three-year window. 

Custom-built mid-level ecommerce app (3-year TCO)

More Cost-Effective Options for Ecommerce Mobile App Development

Today, building a custom native app is not the only way build your own app.

Services like MobiLoud take your existing ecommerce website and turn it into a fully branded iOS and Android app. 

MobiLoud does this by building a native layer on top of your site, which includes all the native elements you need (native navigation, some UI elements, push notifications).

The underlying content and functionality is all powered by your website - meaning you’re not rebuilding this, you’re extending what you’ve already built.

Your site's checkout, product pages, loyalty programs, and every other feature carry over automatically. Updates to your website appear in the app automatically, with no separate codebase to maintain.

This saves you massively - not just on the initial build, but also long-term maintenance costs.

MobiLoud web-to-app conversion (3-year TCO)

MobiLoud Growth plan at $799/month. Annual billing ($679/month) reduces the 3-year total to approximately $26,000.

Based on these estimates, the difference is significant: over three years, a custom build costs roughly 6-12x more than MobiLoud.

That’s not to mention the opportunity cost, and faster time to revenue. MobiLoud ships your app in roughly 30 days, compared to 6-15 months for a custom build.

That means you’re making money from the app faster, and the development project takes away less of your team’s focus from other areas of your business.

"A custom app build for our Salesforce Commerce Cloud setup would have been prohibitively expensive. MobiLoud was the only realistic option."
-- Nick Barbarise, Director of IT, John Varvatos

But are you limiting yourself by going with a more cost-effective option, like MobiLoud?

Not really. For ecommerce apps, which often don’t need any complex app-specific functionality, the end result is barely discernible from a fully custom app.

John Varvatos sees 10x revenue per user from the app vs mobile web, with a 4x higher purchase rate and close to seven figures in app sales since launch.

Many other brands see sometimes millions in annual revenue through their app, without the expense and hassle of a custom native build.

It’s 100% viable to build an ecommerce app this way. In fact, the real question is whether or not spending six figures on a custom app is a viable option.

DIY No-Code App Builders

Another option is to use a traditional template-based no-code app builder.

The quality these tools are capable of putting out is quite impressive, and there’s a real question that it’s better to build an app using a no-code tool than paying for a custom native app.

There are some limitations or issues with DIY no-code tools to consider:

• You often can’t do everything you want with these tools, due to the limitations of their pre-built blocks and templates
• Some of your website’s functionality may not carry over to the app (you’re reliant on their supported integrations)
• The app needs to be managed separately from your website; maintenance is not as much as with a custom app, but more than with an approach like MobiLoud.
• It takes up your time (or your team’s time) to build and manage the app (factor in labor costs alongside the price you see on your invoice).
• The majority of mobile app builders only support Shopify - the market is much thinner if you’re on any other platform (Magento, Salesforce Commerce Cloud, or any legacy/enterprise platform).

In general, for the average Shopify store, a no-code tool is likely a better approach than a fully custom native app.

However, MobiLoud typically beats out these tools in terms of TCO.

The upfront/monthly cost is similar, yet with MobiLoud you spend less time on maintenance, since your app and website are automatically synced.

DIY tools are a good choice if you’re looking to build a very unique app, separate from your website.

If your goal is to extend your existing website’s experience, MobiLoud is the way to go.

What ROI Can You Expect From an Ecommerce App?

Cost only matters relative to what you get back. Here's what the data shows:

Revenue per user

Apps drive 3.5-7x higher average revenue per user compared to mobile web. This isn't theoretical. MobiLoud's 2025 Benchmark Report outlines this lift, often leading to outsized revenue contributions from brands’ mobile apps:

• One wellness brand generates 62% of total online revenue through the app, from only 15.8% of users
• A luxury fashion brand sees 20.7% of revenue from the app, with only 7% of total users
• A cosmetics brand drives $1.82M in app revenue, accounting for 15.2% of total online sales

Conversion rates

App users convert at 1.7-3x higher rates than mobile web visitors. Some MobiLoud brands see even larger gaps, with app conversion rates 8-10x higher than mobile web.

Retention and lifetime value

This is the real story. Apps aren't about acquiring new customers. They're about keeping the ones you already have.

• App customer LTV is 2.8-5x higher than web-only shoppers
• 60% of first-time app buyers make at least one additional purchase
• App users purchase roughly 33% more frequently than non-app users
• Users spend 201.8 minutes per month in shopping apps vs 10.9 minutes on mobile websites

Push notifications: the highest-ROI retention channel

Push notifications are the primary reason ecommerce brands build apps. 

Push gives you a zero-cost, direct line to your best customers. They’re not constrained by inbox filtering, ad costs or carrier fees, and show up on the customer’s lock screen with virtually guaranteed visibility.

They’re a powerful way to drive net-new sales, via promo alerts, new product drop notifications, back-in-stock alerts, and more.

In fact, abandoned cart notifications alone have the potential to add 5-6 figures in new revenue per month; potentially paying for the cost of your app by themselves.

"Push notifications are the cheapest and most powerful communication channel we have. Users who prefer to interact via an app are more loyal, buy from us more often, and spend more time with our content."
-- David Cost, VP of Ecommerce & Marketing, Rainbow Shops

The ROI math

Apps typically contribute anywhere from 10-35% of a brand’s total revenue, on average.

If you’re doing $5M per year in revenue overall, you could potentially drive $1M per year in app revenue (20%).

With MobiLoud, that equates to the following ballpark figures:

• Cost: ~$11,000 (setup fee + Growth plan)
• App revenue: $1,000,000
• Net return: $989,000
• ROI (cost to revenue): ~90x

The math can still work for a custom app. But you’re pushing the timeline back 6+ months, which pushes back the time to revenue, and the time to make back the cost of your investment.

Yet for MobiLoud, the cost is so small (and the potential return so big), that it’s a true no-brainer. 

How to Decide Which Approach Is Right for Your Brand

Not every brand needs the same approach. Here's a framework:

Choose custom development if:

• You're building a marketplace with multiple sellers and complex transaction logic
• Your app requires native device features that can't be delivered through a website (offline mode, Bluetooth, AR, device sensors)
• You need functionality that doesn't exist on your website and can't be built as a web feature
• You have a dedicated technical team to maintain the app long-term
• Your budget supports $100,000+ upfront and $30,000+/year in maintenance

Choose a web-to-app solution like MobiLoud if:

• You already have a working ecommerce website on Shopify, WooCommerce, BigCommerce, Magento, or another platform
• Your primary goal is retention, repeat purchases, and customer LTV (not net-new functionality)
• You want push notifications as a marketing channel
• You need the app to stay in sync with your website without managing two platforms
• You want to be live in weeks, not months
• Your budget is better allocated to marketing and growth than to app development

"When I heard about MobiLoud and that we could turn our website into a native app without additional development resources, it made perfect sense."
-- Steven Kachtan, CIO, Dream On Me (buybuyBaby)

Choose a DIY app builder if:

• You're on Shopify only (most builders are Shopify-exclusive)
• You have a simple store with minimal customizations
• You want to self-manage the app experience (and have the resources to do so)
• You're comfortable with template-based design and limited integration options

When not to build an app

Sometimes, an app isn’t the right move. It can be a powerful asset, but it’s not a panacea.

Your website is almost always the #1 focus. It’s where all your new customers land, and what deserves your attention first and foremost.

If your website isn’t performing well (especially on mobile), fix this first, then think about extending it to an app.

And if you’re still in the early stages in terms of revenue (say sub-$1M annually), you’re usually better served focusing on acquisition at this stage.

An app isn’t for everyone. It’s for the top 10-20% of your customers. When you’re an early stage brand, you likely don’t have enough customers to justify the cost, and may be better off revisiting it at a later stage.

How to Reduce Ecommerce App Development Costs

If you've determined that custom development is the right path, here are practical ways to manage costs:

Start with an MVP

Launch with core features (catalog, cart, checkout, push notifications) and add complexity based on user feedback and data. An MVP approach can significantly reduce initial costs while getting you to market faster.

Use cross-platform frameworks

React Native and Flutter let you build for iOS and Android from a single codebase, reducing development cost by 30-40% compared to native builds for both platforms. For most ecommerce use cases, the performance tradeoff is negligible.

Build on your existing backend

If you're on Shopify, WooCommerce, or another established platform, build your app as a frontend that connects to your existing backend via APIs. Don't rebuild what already works.

Phase your feature releases

Budget $40,000-$60,000 for a solid launch, then allocate $15,000-$25,000 per quarter for feature additions. This spreads cost over time and lets you prioritize based on actual user behavior.

Consider hybrid approaches

Your app doesn't have to be 100% custom-built or 100% web-based. Some brands use a web-to-app approach for their core shopping experience and layer in custom native features where they add unique value.

Launching a High-ROI Ecommerce Mobile App

The question most brands should be asking isn't "how much does ecommerce app development cost?" It's "how can I launch an app that drives the best ROI?"

Most brands think they need a full custom build, and that anything less means sacrificing quality. Yet as many of the world’s biggest apps show, this is not always the case.

You’ve got a working website. It runs great on mobile. Do you really need to reinvent the wheel when it comes to launching an app?

Converting your existing site into a native app is likely to deliver the same retention and revenue benefits as a fully custom app, at a fraction of the cost and timeline.

MobiLoud turns your existing ecommerce website into a fully branded iOS and Android app, complete with unlimited push notifications, automated cart recovery, and full feature parity with your site.
