E-Commerce App Development Cost — 2026 Guide
What an e-commerce app costs to build — storefront, cart, payments and marketplace features priced out — with realistic 2026 ranges.
E-commerce app development cost ranges widely because "e-commerce" spans everything from a single-brand storefront app to a full multi-vendor marketplace. A branded storefront app usually costs $20,000–$60,000, while a marketplace with vendors, payments and logistics can run $80,000–$200,000+.
What moves the number is how much commerce infrastructure you build — catalog, cart, payments, search, and (for marketplaces) vendor onboarding, split payments and matching. This guide breaks the e-commerce app development cost down by type, the factors that drive it, and where to save.

What it costs
By scope| Tier | Typical range | Timeline | What you get |
|---|---|---|---|
| Storefront app | $20,000–$60,000 | 2–4 months | Catalog, cart, checkout and payments for a single brand — iOS + Android from one codebase. |
| Advanced commerce | $60,000–$120,000 | 4–6 months | Search, recommendations, loyalty, subscriptions and deeper integrations. |
| Marketplace | $80,000–$200,000+ | 5–9+ months | Multi-vendor onboarding, split payments, ratings, logistics and admin tooling. |
What drives the cost
FactorsStorefront vs marketplace
A single-brand store is far cheaper than a multi-vendor marketplace, which needs vendor onboarding, split payments and matching.
Payments & checkout
Cards, wallets, multiple currencies and split payments each add integration and testing.
Catalog, search & recommendations
Large catalogs, fast search and personalised recommendations add real engineering.
Platform (web, iOS, Android)
Cross-platform ships all three from one codebase; native for each roughly doubles cost.
Integrations
Inventory, shipping, ERP, analytics and marketing tools each add build and maintenance.
Scale & performance
High traffic and large catalogs demand caching, CDNs and performance work that add cost.
A multi-vendor marketplace MVP:
- Design & architecture: $10,000–$16,000
- Storefront, cart, checkout, payments: $30,000–$48,000
- Vendor onboarding + split payments: $20,000–$34,000
- Admin, search, launch hardening: $15,000–$28,000
Total: roughly $75,000–$125,000 for a marketplace you can launch with real vendors.
How to spend less without cutting value
- Start single-vendor if you can. Prove demand before building marketplace complexity.
- Use proven payments. Stripe/PSPs and their split-payment tools beat custom.
- Go cross-platform. One codebase for iOS + Android saves 30–40%.
- Defer heavy search/recommendations until catalog size justifies them.
- Plan for scale, don't over-build it — add caching and CDNs as traffic grows.
Frequently asked
How much does an e-commerce app cost to build?
A branded storefront app costs $20,000–$60,000; an advanced commerce app $60,000–$120,000; a multi-vendor marketplace $80,000–$200,000+. Marketplace features are the biggest cost jump.
How much does a marketplace app cost?
A multi-vendor marketplace MVP typically costs $75,000–$125,000, scaling to $200,000+ with logistics, advanced search and heavy traffic. Vendor onboarding and split payments drive the cost.
What makes an e-commerce app expensive?
Marketplace features (vendor onboarding, split payments, matching), large catalogs with fast search and recommendations, multiple payment methods, and building natively for each platform.
Is cross-platform cheaper for e-commerce apps?
Yes — building iOS and Android from one codebase with Flutter or React Native is usually 30–40% cheaper than native, with performance that's more than enough for commerce.
Can I start with a cheaper storefront and scale?
Yes — launch a single-vendor storefront app to prove demand, then add marketplace features, search and integrations once it's validated.
