# Cost to Develop an eCommerce App 2026 | GTS Infosoft

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. The figures below are indicative — when you're ready, run our cost calculator or contact us for a precise quote.

## 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.

## FAQ

### 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.
