E-Commerce App Development Cost in 2026: Real Numbers, Not Ranges
What an e-commerce app actually costs in 2026: storefront, advanced commerce and marketplace tiers priced out, a feature-by-feature table at real hourly rates, and an honest section on when Shopify beats a custom build.
The short answer: a custom e-commerce app costs $5,000–$150,000+ in 2026, and that spread is honest because "e-commerce" covers everything from a single-brand storefront to a full multi-vendor marketplace. A branded storefront app usually lands at $5,000–$20,000; a marketplace with vendor onboarding, split payments and logistics runs $15,000–$150,000+. Most cost guides stop there, at a range so wide it's only useful for getting you onto a sales call. We'd rather show you the arithmetic: cost by tier, by feature at our real hourly rate, by team geography, plus the ongoing costs nobody puts in the proposal. And before any of that, an honest answer to the question most agencies skip.
One number on this page is not an estimate: our Scoping Sprint is $2,300, fixed, takes two weeks, and ends with a clickable prototype, a technical plan and a fixed quote for your build, credited in full if you build with us. Everything else below is honest general guidance; that one is an offer.
First, the question that saves the most money: should you build custom at all?
This is an unusual section for an agency cost guide, because the honest answer costs us work: for many single-brand stores, you shouldn't build custom, at least not yet.
- Shopify or WooCommerce is the right answer when you sell physical products through standard flows (catalog, cart, checkout, shipping) and your differentiation is the product and the brand, not the software. You can be live in days for a monthly subscription plus apps and transaction fees, a rounding error next to even the cheapest custom build. Validating demand on a platform first is not a compromise; it's the correct engineering decision.
- Custom starts to win when the platform starts fighting you. The usual triggers: checkout or pricing logic the platform can't express (complex bundles, B2B price lists, quote-based flows), a mobile app experience that's core to retention rather than a wrapper, deep integrations with your own inventory/ERP/logistics stack, per-transaction platform fees that hurt at your volume, or unit economics that depend on owning the data and the experience end to end.
- Marketplaces are almost always custom territory. Vendor onboarding, split payments, matching, per-vendor dashboards and payouts are exactly the things off-the-shelf platforms do worst. If you're building a marketplace, the rest of this guide is priced for you.
A useful rule: if a platform can express your business model, use the platform to prove the model; build custom when the platform becomes the bottleneck, not before. We regularly inherit clients who started on Shopify, hit its ceiling with real revenue and real data, and wrote a far better spec for the custom build because of it. That path costs less in total than starting custom and guessing.
Three caveats that make the tier numbers below trustworthy rather than marketing:
- They assume a senior team working at offshore rates (ours blend to about $20/hour). The same scope at US agency rates costs six to twelve times more, and that spread is cost of living, not skill. The full rate comparison is further down.
- They assume cross-platform mobile: one Flutter or React Native codebase shipping iOS and Android. Building natively for each platform roughly doubles the cost; one codebase saves 30–40%.
- The single biggest jump is storefront to marketplace. A second vendor isn't a feature; it's a second side of your business, with its own onboarding, payouts, dashboards and disputes. Founders write "multi-vendor" in a sentence and it moves the budget by an order of magnitude.

What it costs
By scope| Tier | Typical range | Timeline | What you get |
|---|---|---|---|
| Storefront app | $5,000–$20,000 | 2–4 months | Catalog, cart, checkout and payments for a single brand: iOS + Android from one codebase. |
| Advanced commerce | $10,000–$100,000 | 4–6 months | Search, recommendations, loyalty, subscriptions and deeper integrations on top of the storefront. |
| Marketplace | $15,000–$150,000+ | 5–9+ months | Multi-vendor onboarding, split payments, ratings, logistics and admin tooling. |
What drives the cost
FactorsStorefront vs marketplace
The #1 driver. A single brand with a single seller sits at the cheap end; multi-vendor with onboarding, split payments and matching is the expensive end, because a marketplace is several connected applications.
Payments & checkout
One PSP with cards only is the cheap end; cards plus wallets plus multiple currencies plus split payments is the expensive end. Each method adds integration and testing, and payments bugs are the expensive kind.
Catalog, search & recommendations
Hundreds of SKUs with basic filters is cheap; a large catalog with fast faceted search and personalised recommendations is real engineering, not configuration.
Platforms
Cross-platform (one codebase for iOS + Android) is the cheap end. Native for each platform roughly doubles the mobile cost; cross-platform saves 30–40%.
Integrations
Payments and email are the cheap end; inventory, shipping, ERP, analytics and marketing tools are the expensive end. Each adds build time and permanent maintenance.
Scale & performance
Launch traffic is cheap. High traffic and large catalogs demand caching, CDNs and performance work: real cost, but mostly deferrable until revenue justifies it.
A multi-vendor marketplace MVP, with real vendors, real payments, ready to launch:
- Design & architecture: $3,000–$6,000
- Storefront, cart, checkout, payments: $3,000–$5,000
- Vendor onboarding + split payments: $5,000–$20,000
- Admin, search, launch hardening: $5,000–$20,000
All in: roughly $16,000–$51,000 for a marketplace you can launch with real vendors, scaling toward $150,000+ only when logistics, advanced search and heavy traffic demand it. Cross-check it against the feature table further down: the numbers reconcile, which is the test any quote should pass. If a marketplace is your model, our marketplace development page covers how we structure these builds.
How to spend less without cutting value
Legitimate cuts (do these):
- Start single-vendor if you can. Prove demand before building marketplace complexity. The upgrade path from storefront to marketplace is real; the refund path from an unused marketplace is not.
- Use proven payments. Stripe and the major PSPs, including their split-payment tooling, beat custom payment logic on cost, compliance and reliability. Custom code here is almost always a liability, not an asset.
- Go cross-platform. One Flutter or React Native codebase for iOS + Android saves 30–40% versus native-per-platform, with performance that's more than enough for commerce.
- Defer heavy search and recommendations until catalog size justifies them. Basic filtering on a 300-SKU catalog needs no search infrastructure; build the fancy version when the data says users need it.
- Plan for scale, don't pre-build it. Add caching and CDNs as traffic grows. Architecture should allow scale from day one; implementing scale is a launch-plus problem.
Cuts that feel smart and cost you double later:
- Skipping QA on checkout and payments: your first customers become your QA team at the exact moment their card is out.
- Junior-only teams for anything that moves money: the rework isn't a rebuild, it's a rebuild plus refunds plus a trust deficit.
- No analytics: a store without funnel tracking can't tell you where buyers abandon, which is the only question that matters after launch.
- Skipping scoping: the most expensive sentence in commerce builds is "while you're in there, can vendors also…" three weeks in.
Feature-by-feature: what the pieces cost
The pattern to notice in the cost drivers above: marketplace features and catalog scale are the silent killers. Payment integrations feel scary but are well-trodden; "we'll also let brands sell through us" is a sentence that quietly triples the project. Below are real engineering hours, priced at our blended senior rate of $20/hour.
| Feature | Hours | Cost |
|---|---|---|
| Product catalog + search & filtering | 60–120 | $1,200–$2,400 |
| Cart + checkout flow | 60–100 | $1,200–$2,000 |
| Payment gateway (cards + wallets, one PSP) | 40–80 | $800–$1,600 |
| Inventory management | 40–80 | $800–$1,600 |
| Order management + admin panel | 60–120 | $1,200–$2,400 |
| Ratings & reviews | 25–50 | $500–$1,000 |
| User accounts & auth (email + social) | 30–50 | $600–$1,000 |
| Notifications (order status: email, push) | 30–50 | $600–$1,000 |
| Mobile app shell (Flutter / React Native, iOS + Android) | 80–140 | $1,600–$2,800 |
| DevOps: CI/CD, environments, monitoring | 30–60 | $600–$1,200 |
| Multi-vendor marketplace features (vendor onboarding, vendor dashboards, split payments, payouts) | 250–1,000 | $5,000–$20,000 |
Design (15–20% of build hours), project management (10%) and QA (15%) sit on top of raw feature hours, or make sure they're already inside any quote you're comparing. A quote that looks 25% cheaper often just moved QA into "not included."
Sanity check the table against the tiers: sum the storefront rows and you land inside the $5,000–$20,000 storefront range (a lean launch skips some rows; a polished one takes the high end of each). Add the marketplace row and you're at $15,000+ before logistics and scale work, which is exactly where the marketplace tier starts. When a feature table and a tier table reconcile, the numbers are arithmetic; when they don't, one of them is marketing.
Who should build it: rates compared, honestly
| Freelancer (offshore) | Senior India studio | Eastern Europe agency | US/EU agency | |
|---|---|---|---|---|
| Blended hourly | $15–$25 | ~$20 | $45–$80 | $120–$250 |
| Storefront app | $4,000–$15,000 | $5,000–$20,000 | $15,000–$60,000 | $40,000–$150,000+ |
| Who it fits | Simple, well-specced scope you can supervise yourself | Founders who want senior engineers without US overhead | EU-timezone preference | Enterprise procurement, on-site needs |
The middle row is the same arithmetic: the hours in the feature table above don't change with geography, only the rate does. A storefront that takes 250–1,000 engineering hours costs $5,000–$20,000 at our blended $20/hour and six to twelve times that at $120–$250/hour.
The honest version of the offshore pitch, from an India-based studio whose clients are mostly in the US and Europe:
- The savings are real, 60–80% against US rates, and they come from cost of living, not lower skill. The engineers building checkout flows for US brands and the engineers building yours overlap heavily.
- The risks are also real. The bad outsourcing stories happen, usually with body shops that put five juniors under one distant "architect," communicate only through a project manager, and treat the spec as a contract to lawyer over rather than a product to think about. Payments and inventory are exactly where junior-built systems fail expensively.
- What actually predicts a good outcome: you talk directly to the engineers building your product, the team is senior and small, overlap hours with your timezone are guaranteed in writing, and you see working software every week, not slide decks. If a vendor fails any of those four, the hourly rate doesn't matter. This is how we structure engagements: the specifics are on how we work, and the results are in our portfolio.
How AI-assisted development changes the math in 2026
Every agency now claims "AI-accelerated development." Here's what's actually true from using these tools daily on commerce builds:
- Real gains: meaningful time savings on well-understood features, CRUD screens, admin panels, standard integrations, test coverage, boilerplate. E-commerce has a lot of well-understood surface area, which is part of why a storefront app can start at $5,000 today.
- Near-zero gains on the parts that were always the hard parts: catalog data modelling, payment edge cases (partial refunds, failed split payouts, currency rounding), inventory race conditions, security review, and anything novel enough that the model has no pattern to lean on.
- The catch: AI-generated code reviewed by juniors is negative productivity. It produces confident, plausible, subtly wrong systems at unprecedented speed. In commerce, "subtly wrong" means money moving incorrectly. The teams getting real gains use AI as leverage for senior engineers, not as a substitute for them.
Net effect on your budget: quotes for equivalent scope are genuinely 15–25% lower than two years ago. Be suspicious of anyone promising 70% AI discounts; they're describing demos, not products that handle other people's payments.
The hidden and ongoing costs nobody puts in the proposal
Budget these or they'll budget themselves:
| Line item | Typical cost | Notes |
|---|---|---|
| Payment processing fees | ~2–3% + a fixed fee per transaction | Not a build cost, but the largest permanent line on your P&L. Model it into unit economics before you build |
| Hosting & infrastructure | $30–$200/mo at launch | Scales with traffic and catalog size, not ambition; product-image storage and CDN grow first |
| Third-party services (email, SMS, search, monitoring) | $30–$200/mo | Transactional email and order-status SMS add up first |
| Shipping & logistics APIs | Varies by carrier and volume | Per-label and per-tracking-request pricing: check your carrier's rate card |
| Apple + Google developer accounts | $124/yr | $99/yr Apple, $25 one-off Google |
| Legal: ToS, privacy, returns policy | $300–$2,000 | Templates exist; cross-border selling shouldn't use them blindly |
| Maintenance & iteration | 15–20% of build cost/yr | The one everyone skips. Commerce apps live under constant change: PSP API updates, OS releases, catalog growth, conversion experiments. A store you can't afford to iterate on will lose to one that ships weekly. |
The scale point deserves emphasis: hosting at launch is cheap, and it should stay cheap until traffic proves otherwise. High traffic and large catalogs eventually demand caching, CDNs and performance work: real cost, but cost you incur after revenue justifies it, not before.
When you shouldn't build a custom e-commerce app at all
We turn away builds that fail these checks, because they'd fail anyway:
- A platform can express your model and you haven't tried it. If Shopify or WooCommerce can run your store, run your store on it first. Come back for custom when you have revenue, data and a list of things the platform can't do; that list is the best spec you'll ever write.
- You're building a marketplace without either side committed. If you don't have vendors or buyers lined up, a $16,000–$51,000 build proves nothing a landing page and twenty phone calls wouldn't. Marketplaces die of empty shelves, not missing features.
- The app is a wrapper. If the mobile app would just mirror your website with no offline, camera, or push-driven behaviour that earns its place, a responsive web storefront does the job at a fraction of the cost. See our mobile app cost guide for when native earns its keep.
- The budget only covers the build. If $20,000 is everything you have, don't spend $20,000 on version one. Keep 15–20% per year for iteration; conversion optimisation after launch routinely matters more than any feature in the initial scope.
If what you're really validating is a product idea rather than a store, start smaller: our MVP development service and MVP cost guide cover that path. Subscription software with a commerce layer is different economics again: see the SaaS cost guide.
Or skip the estimating entirely
Everything above helps you sanity-check quotes. But the honest limitation of any cost guide, including this one, is that your product isn't a table row.
That's what our Scoping Sprint is for: $2,300, fixed price, two weeks. You get a clickable prototype of your product, a technical plan, and a fixed quote for the build: a number, not a range, that we commit to. If you build with us, the $2,300 is credited against the build. If you don't, you own everything we made and can take it to any competent team, including any agency in the rate table above.
We publish the price because we think "book a call to find out" is a tax on founders' time. See what's included →, or just tell us what you're building.

Frequently asked
How much does an e-commerce app cost to build in 2026?
A branded storefront app costs $5,000–$20,000; an advanced commerce app $10,000–$100,000; a multi-vendor marketplace $15,000–$150,000+. Marketplace features are the biggest cost jump: vendor onboarding and split payments turn one application into several.
How much does a marketplace app cost?
A multi-vendor marketplace MVP typically costs $16,000–$51,000, scaling to $150,000+ with logistics, advanced search and heavy traffic. Vendor onboarding and split payments drive the cost: they're the difference between a store and a platform.
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 currencies, and building natively for each platform instead of one cross-platform codebase.
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-per-platform, with performance that's more than enough for commerce. Native-for-each roughly doubles the mobile cost.
Can I start with a cheaper storefront and scale to a marketplace?
Yes, and you usually should. Launch a single-vendor storefront app to prove demand, then add marketplace features, search and integrations once it's validated. The architecture choices that keep that path open cost little; building marketplace complexity before demand costs a lot.
Should I build custom or use Shopify/WooCommerce?
If a platform can express your business model (standard catalog, cart, checkout, shipping) use the platform to prove the model. Build custom when the platform becomes the bottleneck: checkout logic it can't express, an app experience core to retention, deep ERP/logistics integration, or fees that hurt at your volume. Marketplaces are almost always custom territory.
How long does an e-commerce app take to build?
A storefront app typically takes 2–4 months; advanced commerce 4–6 months; a marketplace 5–9+ months. Timelines slip for the same reason budgets do: scope added mid-build, usually marketplace features, not slow engineering.
What ongoing costs should I budget after launch?
Payment processing fees (roughly 2–3% plus a fixed fee per transaction, the largest permanent line), hosting and third-party services (typically $60–$400/month early on, growing with traffic), and 15–20% of the build cost per year for maintenance and iteration. A store you can't afford to change will lose to one that ships weekly.
