Compare 12 ecommerce app development agencies serving US brands by services, pricing, development model, strengths, limitations, and ideal use cases.
An ecommerce app can cost $50,000 to $300,000 when commissioned from a custom development agency. The first release may take six months. Maintenance, operating-system updates, and new integrations add to the bill after launch.
That level of investment makes sense when the app needs proprietary technology. It is harder to justify when a retailer wants a faster storefront, native product pages, checkout, customer accounts, loyalty, subscriptions, and push notifications. Specialized commerce platforms can handle much of that work with shorter launch timelines and fewer engineering resources.
We reviewed 12 companies that take different approaches to ecommerce app development. The list includes custom development agencies, enterprise consultancies, Shopify-focused platforms, and services that package an existing website as an app.
Each company was assessed using six questions:
- Has it built apps for ecommerce businesses?
- Can shoppers test its published work?
- Does it build native interfaces, cross-platform apps, or webviews?
- Which commerce platforms and third-party integrations does it support?
- What does implementation cost, and how long does it take?
- What happens after the app launches?
TL;DR
- The market splits into three build models: custom agencies ($50K–$300K+), offshore development shops ($10K–$50K), and productized app platforms (low monthly cost, live in weeks). Most of the "which agency" question is really a "which model" question.
- Custom agencies make sense for genuinely custom needs: complex ERP integrations, marketplace logic, or a flagship app that is itself the product. For a standard Shopify storefront, they are usually overkill.
- Appbrew is the top pick for Shopify and Shopify Plus brands that want a native app without a custom build. US brands like Kiyoko Beauty (60% higher conversion on app vs web) and Karma and Luck (50% higher CVR) run on it.
- Budget 15–20% of your original build cost per year for maintenance, whichever model you pick. The apps that fail usually fail here, not at launch.
- The strongest signal that an app is worth building is your repeat-purchase rate. Above 20%, an app pays for itself through retention. Below 10%, fix retention first.
What the best ecommerce app development agencies actually do
An ecommerce app development agency builds and maintains a native mobile app (iOS, Android, or both) that connects to your existing store's catalog, checkout, and customer data. The good ones do more than ship an app. They own the parts you don't want to staff internally.
A full-scope engagement usually covers:
- Discovery and architecture: auditing your platform, mapping integrations, and defining the feature set before anyone writes code.
- UX and UI design: wireframes and high-fidelity screens for product pages, cart, checkout, account, and push flows.
- Development: building the app and wiring it to your backend (catalog, inventory, orders, payments) plus third-party tools like loyalty, reviews, and analytics.
- QA and store submission: testing across real devices and OS versions, then handling the Apple and Google review process.
- Post-launch maintenance: OS updates, bug fixes, and new features, which is where most of the long-term cost lives.
The models differ in how much is built for one retailer. A custom agency scopes and develops the application around proprietary requirements. A productized platform supplies commerce infrastructure that can be configured for the brand. The app builder versus custom development comparison covers the operational differences in more detail.
How we evaluated these ecommerce app development companies
Our research went beyond company websites and marketing claims. Where apps were publicly available, we downloaded and used them firsthand, testing key shopping journeys such as product discovery, search, product pages, cart, checkout, login, and customer accounts. We also looked for signs of native interfaces, cross-platform development, and webview-based experiences.
To evaluate reputation and results, we reviewed published case studies, App Store and Google Play feedback, Shopify App Store and G2 ratings where applicable, and customer discussions on Reddit and other independent platforms.
We compared these findings with service documentation, portfolios, pricing pages, and third-party company profiles to assess each provider’s capabilities, limitations, and real-world ecommerce experience.
Each company was evaluated using the same criteria:
- Ecommerce experience: Evidence of apps built for retailers, marketplaces, or commerce businesses.
- Development model: Custom development, cross-platform engineering, website-to-app conversion, or a productized app platform.
- Mobile architecture: Whether key shopping experiences are native, cross-platform, or delivered through webviews.
- Platform expertise: Experience with Shopify, Adobe Commerce, Magento, WooCommerce, or custom commerce backends.
- Integration capabilities: Support for payments, loyalty, subscriptions, reviews, analytics, marketing, ERP, CRM, and order-management systems.
- Published work: Availability of live apps, portfolios, client examples, and measurable ecommerce outcomes.
- Cost and launch time: Published pricing, estimated project ranges, implementation requirements, and expected timelines.
- Post-launch support: Maintenance, operating-system updates, app-store management, bug resolution, and continued development.
Editorial disclosure: Appbrew publishes this comparison and is included in the list. Its position is based on the evaluation criteria above and its suitability for established retailers. Pricing, services, and platform capabilities can change, so you should verify current information before selecting a provider.
The 12 best ecommerce app development agencies in the USA (2026)
This list spans every model and price point, from productized platforms to enterprise custom shops, so you can match an agency to your actual budget and complexity.
Some are suited to retailers launching a standard shopping app. Others make more sense for marketplaces, unusual buying flows, or enterprise systems that require extensive backend work.
Here is a quick comparison before we examine each company in detail.
1. Appbrew
Appbrew is a no-code Shopify mobile app platform used by more than 250 ecommerce brands. It builds native iOS and Android storefronts for Shopify and Shopify Plus retailers, including US brands such as Svaha USA, Anatomie, Karma and Luck, Dermaclara, and Mixology.
The app stays connected to the retailer’s Shopify catalog, inventory, checkout, customer records, and order data. It also works with the loyalty, subscription, review, support, and marketing tools already used by the store. Ecommerce teams can change app layouts, collections, content, and campaigns without maintaining separate iOS and Android codebases.
Standout strengths:
- Purpose-built for ecommerce: personalization, push notifications, subscriptions, and 120+ integrations with Shopify apps brands already run.
- Proven US results: Kiyoko Beauty (60% higher conversion on app vs web, 33% higher AOV), Karma and Luck (50% higher CVR, 25% AOV growth), Anatomie (5x higher LTV).
- Weeks, not quarters: the same conversion lift a $150K custom build delivers, because the gain comes from the channel (a native app with push access), not bespoke code.
Key features
- Native iOS and Android storefronts
- Real-time synchronization with Shopify products, collections, inventory, customers, and orders
- No-code tools for changing layouts and app content
- Native search, product pages, customer accounts, and checkout
- Unlimited push notifications with segmentation and deep links
- Loyalty, subscription, reviews, support, and marketing integrations
- More than 120 integrations, including Klaviyo, Yotpo, Recharge, and LoyaltyLion
- AI-assisted personalization, product recommendations, size guidance, and shopping support
- App analytics and event tracking for GA4, Firebase, Meta, and other marketing tools
Appbrew pros and cons
Pricing
Appbrew pricing starts at $199 per month.
Pro at $599 per month.
Enterprise: custom pricing.
Best for: US Shopify and Shopify Plus brands that already have a working ecommerce operation and want to add a native mobile storefront without commissioning separate iOS and Android builds.
Verdict
Appbrew fits established US Shopify brands that want to turn mobile traffic and repeat customers into an owned app channel. Its Shopify connection removes much of the work involved in synchronizing products, inventory, customers, checkout, and orders.

Best for: Enterprises and funded companies building a proprietary ecommerce application, multi-vendor marketplace, or retail system that cannot be assembled from an existing commerce platform and standard integrations.
Verdict
Pick Appinventiv when your app is a large, integration-heavy build and offshore delivery at scale is acceptable.

This model suits retailers whose mobile website already provides the desired shopping experience. App speed and interface quality remain closely connected to the underlying website.
Key features
- iOS and Android apps built on the existing mobile website
- Compatibility with the website’s current ecommerce tools
- Existing checkout, account, and payment flows carried into the app
- Unlimited push notifications
- Automated cart-recovery notifications
- App Store and Google Play submission
- Ongoing updates and maintenance

- Business: $1,499 per month
- Enterprise: custom
Best for: Retailers with a well-designed mobile website that want an app without rebuilding their storefront and integrations in a separate system.
Verdict
MobiLoud reduces duplicate development by using the website as the source of the app experience. This can work well for stores whose websites already support custom pricing, account rules, and uncommon integrations. Brands seeking native product pages, native navigation, or an app experience that differs substantially from the website should consider another development model.
7. Konstant Infosolutions

BairesDev pros and cons
Pricing
Custom quote.
Best for: Enterprises with proprietary catalog, pricing, checkout, or marketplace requirements, including teams that need additional mobile engineers.
Verdict
BairesDev is an engineering partner rather than an ecommerce app product. It can provide the people needed to build custom systems or extend an internal team. That flexibility suits proprietary products, but it also places more product management and long-term ownership on the retailer.
10. Simform
Simform is a digital engineering company with offices across the United States. Its mobile practice builds native iOS and Android applications along with cross-platform products using React Native, Flutter, and Xamarin.
The company’s ecommerce work covers product catalogs, shopping flows, account systems, backend services, API connections, and cloud infrastructure.

Simform pros and cons
Pricing
Custom quote.
Best for: Retailers and software companies building commerce apps that require substantial API, cloud, microservices, or backend work.
Verdict
Simform fits projects where the mobile interface cannot be separated from the infrastructure behind it. Its cloud and backend work distinguishes it from mobile-only studios. A retailer with a working Shopify backend and conventional storefront requirements may use only a small part of those capabilities.
11. Dinarys
Dinarys is an ecommerce development company with experience in mobile apps, online stores, marketplaces, and platform migrations. It works with Shopify, Adobe Commerce, Magento, BigCommerce, and custom commerce systems.

Pricing
Dinarys states that ecommerce app development ranges from $30,000 for a basic application to $150,000 or more for an enterprise product.
Best for: Retailers that need custom mobile development alongside Shopify, Adobe Commerce, Magento, or marketplace engineering.
Verdict
Dinarys has a clearer commerce focus than a general mobile agency. That matters when the project involves a store migration, custom Magento modules, or work across the commerce backend and mobile app. Shopify brands that do not require custom backend development should compare its project cost with a native app platform.
12. Zco Corporation
Zco Corporation is a US mobile app development company founded in 1989. It has offices in New Hampshire, Massachusetts, and New York and reports a team of more than 250 mobile development specialists.
The company develops native iOS and Android apps, cross-platform applications, progressive web apps, and custom backend systems. Its technology stack includes Swift, Kotlin, React Native, Flutter, .NET MAUI, AWS, and Azure.

- React Native and Flutter development
- Progressive web app development
- UX and interface design
- Custom backend and API integration

- A medium-complexity app costs approximately $100,000
- A complex app costs $200,000 or more
The company states that custom mobile applications typically take three to nine months from concept to launch.
Best for: US companies that want a domestic development partner for a proprietary mobile application with custom backend or integration requirements.
Verdict
Zco is a strong fit when US presence and a long operating history are important selection criteria. Its team can handle the interface, mobile code, backend, cloud infrastructure, and release process. Retailers should confirm how much ecommerce-specific experience the proposed delivery team has before committing to a custom build.
Questions to ask before hiring an ecommerce app development agency
A polished proposal can hide important differences in architecture, ownership, maintenance, and ongoing costs. Ask each company the same questions so you can compare the answers directly.
1. Can we download and test ecommerce apps you have built?
Ask for live App Store and Google Play links. Prioritize apps built for retailers with a similar catalog size, ecommerce platform, and technology stack.
Test the search, filters, product pages, cart, checkout, login, order history, and account features. Check how quickly screens load and whether any part of the shopping flow opens a mobile webpage.
Screenshots and prototypes do not show how an app performs with real shoppers, live inventory, and third-party integrations.
2. Is the app native, cross-platform, or webview-based?
These terms describe different technical approaches.
A native app uses mobile interfaces built for iOS and Android. Cross-platform frameworks such as React Native and Flutter share code across both platforms while retaining access to native device features. A webview displays website content inside an app container.
Ask the company to identify which screens are native and which use webviews. Product pages, search, customer accounts, subscriptions, loyalty, and checkout deserve particular attention.Our PWA versus native app guide explains where browser-based and native experiences differ.
3. Have you worked with our ecommerce platform?
Experience with a platform such as Shopify, Adobe Commerce, Magento, BigCommerce, or WooCommerce reduces the amount of custom integration work.
Ask how the company handles product data, customer accounts, discounts, inventory, checkout, payments, taxes, and order creation on your platform. A general mobile developer may understand app engineering without understanding the commerce rules behind the storefront.
4. Which parts of our existing technology stack will work in the app?
Prepare a list of the tools used for search, loyalty, subscriptions, reviews, customer support, analytics, attribution, returns, and marketing automation.
Ask the company to classify each integration as:
- Already supported
- Available through an API
- Displayed through a webview
- Requiring custom development
- Not supported
A logo on an integrations page does not confirm that every feature works natively inside the app. Use this Shopify mobile app integrations guide to build a stack-specific checklist before vendor calls.
5. How will store data stay synchronized?
Products, variants, prices, inventory, customer records, discounts, and orders should remain consistent across the website and app.
Ask whether synchronization happens in real time, through webhooks, on a fixed schedule, or through manual updates. Find out what happens when an API request fails or inventory changes while a customer is checking out.
The app should not create a second catalog that the ecommerce team has to maintain.
6. Who owns the source code and customer data?
A custom development contract should state who owns the application code, designs, documentation, and backend systems. A platform agreement should explain what the retailer owns and what remains the provider’s intellectual property.
The retailer should retain access to customer data, analytics, attribution data, and campaign history. Ask which formats are available if the information needs to be exported.
7. Who controls the Apple and Google developer accounts?
The app should be published through developer accounts owned by the retailer. This keeps the store listing, bundle ID, package name, ratings, reviews, and install history under the brand’s control.
If the provider publishes through its own account, ask what happens when the contract ends or the brand moves to another company.
8. What is included in the quoted price?
Request a written breakdown covering:
- Product strategy and discovery
- UX and interface design
- iOS and Android development
- Backend development
- Third-party integrations
- Quality assurance
- App Store and Google Play submission
- Hosting and infrastructure
- Maintenance and operating-system updates
- Support
- New feature development
Check for setup charges, revenue-based fees, minimum contract terms, API costs, and separate maintenance retainers.
9. How are bugs, OS updates, and new features handled after launch?
Apple, Google, Shopify, payment providers, and third-party apps change their APIs and policies. The mobile product needs ongoing maintenance even when the retailer is not adding features.
Ask what the support agreement classifies as a bug, a platform update, and a new feature. Confirm response times for checkout failures, crashes, login problems, and payment issues.
10. What support is available during US business hours?
Ask where the support team is located and which hours it covers. Confirm the escalation process for urgent issues that affect orders or customer access.
A support promise such as “24/7 availability” should be backed by response-time commitments for critical, high-priority, and routine requests.
11. How will app performance and revenue be measured?
The app should track more than downloads and push-notification opens.
Ask how it measures:
- Conversion rate
- Average order value
- Revenue per user
- Repeat purchase rate
- Customer lifetime value
- App-attributed revenue
- Push-notification revenue
- Install-to-purchase conversion
- Crashes and screen-load times
Confirm that events can be sent to the retailer’s own GA4, Firebase, Meta, and attribution accounts. Conversion rate, average order value, retention, and app revenue should be measured against mobile web using the same definitions. See the mobile conversion rate guide for the metrics that deserve attention.
12. What happens if we end the contract?
This question should be answered before development starts.
Confirm whether the app will remain live, how long the retailer can access the platform, and which data can be exported. Ask whether another provider can reuse the existing bundle ID and package name so customers receive an update instead of downloading a new app.
The exit terms should also cover source code, design files, analytics history, integrations, notification tokens, and technical documentation.
Do you need a custom ecommerce app development agency?
Before you shortlist an agency, identify which requirements cannot be handled by your commerce platform or existing integrations.
Custom development is justified when the mobile product requires proprietary architecture or workflows. A Shopify brand that needs a native catalog, customer accounts, subscriptions, loyalty, checkout, analytics, and push notifications may be able to use an app platform instead.
A custom agency is the right call in a narrow set of cases:
- You need non-standard integrations with a legacy ERP, marketplace, or fulfillment system.
- The app itself is the product, not a companion to your store.
- The buying flow cannot run through your existing commerce backend.
- Your internal team can manage discovery, development, QA, and ongoing maintenance.
Here's a quick way to decide whether an app of any kind is worth it yet:
- Repeat-purchase rate above 20%: an app pays for itself through retention. Build it.
- Mobile traffic above 50% of your total: your shoppers are already mobile-first, so app adoption potential is high.
- Annual revenue above $1M: the app can realistically drive 10–35% of revenue, enough to justify the spend.
- Any of these missing: fix the fundamentals first. An app won't rescue weak retention or a broken mobile site.
Final verdict
There is no single development model that fits every retailer. Appbrew is the most relevant option in this list for established Shopify and Shopify Plus brands that want a native storefront connected to their current commerce stack. MobiLoud fits retailers that want to reuse an existing mobile website. Custom agencies fit marketplaces, proprietary backends, and projects with unusual integration or fulfillment requirements.
Shortlist companies based on live ecommerce work, architecture, integration coverage, ownership terms, support, and three-year cost. Then test the apps they have already shipped.
For Shopify brands evaluating a native mobile channel, book an Appbrew demo to review your store, integrations, and launch requirements.

FAQs
What is the best ecommerce app development company?
The best company depends on the commerce platform and the amount of proprietary development required. Appbrew fits Shopify and Shopify Plus brands that want a native storefront connected to their existing store. A custom agency is more suitable for a proprietary marketplace, unusual fulfillment logic, or a commerce system built outside Shopify.
How much does it cost to hire an ecommerce app developer in the USA?
Published prices in this comparison range from $499 per month for Appbrew to $200,000 or more for complex custom development. Cost depends on the development model, platforms, integrations, backend systems, interface requirements, and post-launch support. Compare the three-year cost rather than the initial price alone.
How long does it take to build an ecommerce app?
A platform-based Shopify app can launch in days or weeks. MobiLoud states that its website-based apps typically take six to eight weeks. Custom ecommerce apps commonly take three to nine months, while enterprise projects with extensive backend work may take longer.
Should I use an ecommerce app development agency or an app builder?
Use an agency when the product requires custom logic, complex integrations, or proprietary architecture. Use an ecommerce app platform when the existing store already handles the catalog, inventory, customers, and checkout, and the goal is to add a branded mobile storefront without developing each layer separately.
What is the difference between an ecommerce app developer and a mobile commerce development service?
An ecommerce app developer handles software engineering. A mobile commerce development service may also cover product strategy, interface design, integrations, app-store submission, analytics, maintenance, and post-launch support. Buyers should check which services are included in the quoted price.
Can Shopify stores create native mobile apps?
Yes. A Shopify store can connect its products, inventory, customers, checkout, and orders to a native iOS and Android app. A Shopify-focused platform handles this connection without requiring the retailer to rebuild its commerce backend or maintain separate mobile development teams.
Who should own the Apple and Google developer accounts?
The retailer should own both accounts. This keeps the app listing, bundle ID, package name, ratings, reviews, and install history under the brand's control. The development company can receive the permissions needed to submit and maintain the app without owning the accounts.
