Android app development cost for e-commerce & retail

There is no single figure, and quoting one would be the least useful thing this page could do — the same pairing spans several-fold depending on scope, compliance and how many surfaces you ship. What this page gives you instead is what the pairing demands: the regimes that may apply, the systems of record you will be asked to integrate with, the device matrix and the release path. The calculator below is already fixed to Android and e-commerce & retail — answer what is left and it returns a cost range, hours, timeline, team and running costs for your scope.

Because e-commerce & retail brings its own obligations before you write a feature: PCI DSS, ADA accessibility, CCPA / CPRA may apply, you will be asked to integrate with systems like Stripe and Shopify, and there are typically 6 distinct roles rather than one. The platform contributes its own separate costs — the device matrix, Google Play review — and those are independent of the industry.

Because you are not shipping to one device family. Android spans thousands of models, four density buckets, five OS versions still in meaningful use, and vendor skins from Samsung, Xiaomi, Oppo and others that change how notifications, background work and permissions behave. A realistic matrix is 20–30 configurations, which is roughly 60–80 hours of QA per release cycle that an iOS-only build simply does not incur.

For Android alone, native Kotlin is usually cheaper — you are not paying a framework premium or writing bridges. Flutter and React Native only win once you need iOS too, at which point one codebase serving both costs roughly 24% more than a single native app instead of 170% more. Choose native if Android is your only target or you need deep hardware access; choose cross-platform if both mobile platforms are in scope and your UI is fairly conventional.

Use a platform unless you have a specific reason not to. Shopify plus a headless front end covers what most stores need, and it absorbs PCI scope, tax calculation and fraud screening. Build custom when your pricing, bundling or fulfilment logic cannot be expressed in a platform, when you are running a marketplace rather than a store, or when the buying experience itself is your differentiator. A common middle path is a platform for commerce plumbing and a custom app for the experience.

Against an existing web store, native apps typically add 50–70% rather than doubling cost, because the catalogue, cart, orders, payments and admin already exist — you are paying for client surfaces and store distribution. What you get is push notifications that actually reach people, saved payment with biometric confirmation, and better repeat-purchase behaviour. For a store with meaningful repeat purchase it is usually worth it; for a considered one-off purchase it usually is not.
