eCommerce App Development Cost in India (2026)
eCommerce app development cost depends on catalogue size, payment modes and how many sellers share the platform. A single-brand store that lists 300 products and ships from one warehouse is a focused build. A marketplace with seller onboarding, commissions, returns and multi-warehouse stock is a different system with settlement at its centre. For 2026, a working catalogue and checkout starts near Rs 2,50,000, while a multi-seller platform with logistics and payouts reaches Rs 35,00,000. 24Bit System quotes from a written feature list.

A shopping app is mostly a set of rules about stock, money and trust. Who reserves inventory when a cart is open, what happens when a payment fails after stock is blocked, and how a return is refunded are the decisions that set the build size. Stores that answer those questions before development starts spend less than stores that discover them in the first sale week.
eCommerce app development cost by stage in 2026
The stages below separate the storefront from the back office. Most retailers launch the first two and add seller or logistics features once order volume shows where the manual work actually hurts.
A single-brand store with its own stock normally costs Rs 5,00,000 to Rs 12,00,000 for web and app together. A marketplace with seller settlement, courier aggregation and multi-warehouse stock sits between Rs 20,00,000 and Rs 35,00,000.
Choosing a platform before listing the rules is the usual mistake. A subscription store is cheap until a seller payout or a partial refund needs custom logic, and then the work is harder than building the rule properly in the first place. The reverse is also common: a custom build for a 200-product catalogue that would run perfectly on a lighter stack.
Photography and catalogue data are the quiet cost. Apps fail on bad images, missing sizes and unclear descriptions far more often than on code. Budget for content before the launch date is set.
Catalogue migration deserves its own budget line. SKUs, variants, images, tax groups and existing URLs have to move without losing search rankings or breaking old links. A redirect map and an image pipeline are small pieces of work that prevent a launch-week drop in traffic.
Hosting for a mid-sized catalogue is typically Rs 18,000 to Rs 60,000 a year, plus image storage and backup. Search, recommendation and email tools are usually subscription products priced by traffic or contact count.
Payment gateway charges are a percentage per transaction. SMS and WhatsApp order updates are billed per message. A support plan after warranty is optional and usually priced as a share of the build cost.
How an eCommerce build is billed
Invoices usually follow the storefront, then the seller or stock layer, then payments and returns, then the app rollout. Keep the final payment until a full sale, cancellation and refund cycle has completed in production, because that cycle touches every module.
Single-brand store or multi-seller marketplace
A single-brand store owns its stock and keeps settlement simple: one bank account, one set of margins. A marketplace adds seller onboarding, commission slabs, payout cycles and disputes, which usually doubles the finance work even when the storefront looks similar.
Retailers often start single-brand and open the platform to partners later. Designing the order and stock model for multiple sellers from day one avoids a painful migration.
What to decide before the first sprint
Decide stock reservation rules, return windows, refund method and who pays return shipping. Decide whether prices include tax and how invoices are numbered. These choices become database fields and reports, and changing them after launch costs more than deciding them now.
