Tablet 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 Tablet 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, App Store & Google Play review — and those are independent of the industry.

On both platforms, yes, technically. Whether you should depends on who uses it. For a consumer app where tablet is 5% of sessions, scaled phone layouts are a reasonable interim and cost nothing. For field, clinical, retail or education software the tablet IS the primary device, and a stretched phone UI wastes the screen that justified buying tablets. Apple also treats a phone-shaped iPad app as a review comment, so if you claim iPad support you need real iPad layouts.

Because the interaction model changes, not just the dimensions. A phone screen shows one thing; a tablet shows a list beside a detail beside a inspector. That means new navigation patterns, split views, drag and drop, keyboard shortcuts, pointer hover states and a layout that survives being run at a third of the screen in split-screen. Expect design to grow more than implementation — typically 1.5–2× the per-screen design cost of the equivalent phone screen.

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.
