Cost to Develop an eCommerce App 2026

Why eCommerce Apps Cost What They Do

What drives an eCommerce app's cost is the machinery behind the storefront — catalog management, cart and checkout, payments, inventory, order tracking and an admin panel — far more than the number of product screens.

GTS Infosoft has shipped shopping and marketplace apps for clients across India, the USA and Australia. At around USD 20/hour with AI-accelerated delivery, our ranges sit well under enterprise agencies.

What Affects the Cost

Platforms
iOS, Android or both, maybe a web store or admin panel too — cross-platform Flutter or React Native ships mobile from a single codebase and trims the cost.
Features
search and filters, cart, wishlists, coupons, reviews, order tracking, push notifications, loyalty programs — each one adds engineering effort.
Complexity
a single-vendor store is far simpler than a multi-vendor marketplace once seller onboarding, commissions and payouts enter the picture.
Design
a conversion-focused custom UI with rich product pages takes more design hours than a templated storefront does.
Integrations
payment gateways, shipping and logistics APIs, ERP/inventory systems, analytics and CRMs all need their own build and testing.

Estimated Cost by Complexity

Simple ($5,000–$11,000)
a single-vendor store app: catalog, cart, one payment gateway, basic order tracking. Indicative only.
Standard ($11,000–$25,000)
custom UI, wishlists, coupons, reviews, an admin panel and a number of integrations. Indicative only.
Complex ($25,000–$55,000+)
a multi-vendor marketplace: seller apps, AI recommendations, serious scalability and plenty of integrations. Indicative only — contact us for an exact quote.

Timeline & How to Reduce Cost

Timeline
count on 8–12 weeks for a simple store app, 3–5 months for a standard app, and 5–8 months for a marketplace.
Launch an MVP
open with catalog, cart and checkout for one vendor, prove that sales come in, then layer on loyalty and marketplace features.
Go cross-platform and offshore
Flutter or React Native paired with GTS Infosoft's ~USD 20/hour AI-accelerated team holds costs down across devices.
Reuse commerce building blocks
cart, payment and catalog modules we've already proven cut the custom effort and shorten the build.

Frequently Asked Questions

How much does it cost to develop an eCommerce app?

Expect $5,000–$55,000+ for an eCommerce app. A single-vendor store app runs $5,000–$11,000, a feature-rich app $11,000–$25,000, and a multi-vendor marketplace $25,000 and up. Indicative ranges — contact us for an exact quote.

How long does it take to build an eCommerce app?

A simple store app generally ships in 8–12 weeks, a standard app in 3–5 months, and a multi-vendor marketplace in 5–8 months. Phased, AI-accelerated delivery gets you selling sooner.

What are the ongoing and maintenance costs?

Set aside roughly 15–20% of the build cost per year, plus payment gateway and hosting usage fees. Monthly support retainers keep those numbers predictable.

What is the cheapest way to build an eCommerce app?

Begin with a cross-platform single-vendor MVP — catalog, cart, checkout — built by a senior offshore team, then add marketplace and loyalty features in stages as the store grows.

Should I build a native app or use a platform like Shopify?

For a straightforward store, a hosted platform is often the cheapest start. Custom pays off once you need a differentiated UX, marketplace logic, deep integrations or full control — we're happy to advise on the right fit for your budget.
