Why ecommerce brands hire us for the app
Most ecommerce teams have already paid for a theme, a dozen plugins and an app builder subscription. They come to an ecommerce app development company when those stop fitting: the app builder cannot show their bundle logic, the wholesale customers still order by email, or the marketplace needs payouts that no plugin handles. What they need next is a build with a known price.
- 01 Price before commitment. You see hours, team size, timeline and cost per feature before any meeting.
- 02 Stage payments. Discovery costs 10 percent of the estimate, at least $1,900. Design, build sprints and launch are each paid before they start, and you can stop after any of them.
- 03 Your store stays the source of truth. Products, inventory, prices and orders stay in the commerce platform you already run, and the app reads and writes through its API. Nobody re-keys a catalog.
- 04 Every connection priced one by one. Each link to your commerce platform, payment processor, ERP, CRM, loyalty program, search or shipping service is a line in the estimate, 16 to 48 hours each.
- 05 Your code, your accounts. The app is built in your repository, published under your Apple and Google developer accounts, and the rights transfer to you as each stage is paid.

An app builder is the right call when your app is your website in a native wrapper. A custom build pays off when the app needs your own logic, when you sell wholesale, or when the builder fee over three years passes the cost of owning the app. After launch, our software maintenance plans keep it updated for new iOS and Android versions.
How an ecommerce app project runs
-
01
Run the estimate. Pick mobile or web, the features and the systems to connect, and see the range in about a minute.
-
02
Discovery and scope, about one week. Customer journeys, catalog and order data model, every platform API and sandbox, and a fixed price for each later stage.
-
03
Design, about two weeks. Product listing, product page, cart, checkout and account screens, unless you bring your own designs.
-
04
Build in two week sprints. You test a live build on your phone at the end of every sprint, connected to a copy of your store, and can reorder the backlog between sprints.
-
05
Launch and handover. App store submission under your accounts, production release, documentation and the code in your repository. Apple and Google review times sit outside the build, so we plan them in from the start.
Who buys ecommerce app development from us
- 01 Direct to consumer brands with repeat buyers who want push, saved carts and loyalty in an app their customers keep.
- 02 Wholesalers and distributors replacing email and phone orders with a B2B ordering portal tied to the ERP.
- 03 Founders launching a marketplace who start lean with our MVP development services.
- 04 Retailers whose app builder or theme stopped fitting their pricing, bundles or fulfillment rules.
- 05 Ecommerce teams that need integrations between store, ERP, CRM and warehouse more than a new storefront.
Questions buyers ask an ecommerce app development company
In our model, a cross-platform shopping app connected to your store costs $74,500 to $95,000, two native apps cost $91,000 to $111,500, and an ecommerce MVP costs $38,500 to $53,500. App store accounts, hosting and platform fees are extra and paid by you directly. The full breakdown is in ecommerce app development cost.
Most ecommerce apps in our model take 8 to 12 weeks of build after a one week Discovery. An MVP takes 5 to 7 weeks. Apple and Google review add calendar time outside the build, usually a few days, so we plan for it in the launch stage.
Yes. The app reads products, inventory and prices and writes orders through the platform's API, so your store stays the source of truth. The platform connection is one line in the estimate, 16 to 48 hours depending on how much custom data your catalog carries.
For most shopping apps, one cross-platform codebase is enough and costs 15 to 18 percent less than two native apps in our model. Native Swift and Kotlin make sense when the app leans on device features such as augmented reality try-on or heavy offline use.
Yes. A B2B ordering portal with company accounts, buyer roles, customer price lists, invoices and ERP and CRM connections costs $65,500 to $94,000 in our model. It replaces email and phone orders for wholesale customers.
You do. Everything is built in your repository and published under your Apple and Google developer accounts, and the rights to each stage transfer to you when that stage is paid.
