How Much Does It Cost to Build an E-commerce Store?
What an online store really costs — platform vs custom, indicative ranges by store type, the running costs people forget, and how to get an accurate fixed quote. International perspective.
“How much does an online store cost?” has the same honest answer as most software questions: it depends — on what you sell, how you sell it, and how much of it is custom. But the ranges are knowable, and the things that move the price are predictable. Here’s a clear, international breakdown.
Figures below are indicative, in US dollars for comparison. Your real number depends on catalogue size, payments, integrations, design and your market — which we’ll unpack.
What drives the cost of a store
- Platform vs custom. A templated store on a platform is cheapest; a custom or headless build costs more but fits exactly and scales.
- Catalogue size. 20 products is a different job from 20,000 with variants, categories and filtering.
- Payments & tax. One gateway is simple; multiple gateways, local methods, VAT/tax rules and compliance add work.
- Integrations. Accounting, ERP, inventory, shipping and CRM connections are often the biggest hidden cost.
- Design. A polished template versus a bespoke, brand-led storefront with custom UX.
- Market / region. Local build rates vary widely across the UK, Europe, North America, the GCC and Africa.
Platform or custom?
This single choice sets the budget more than anything else.
Platform (Shopify, WooCommerce, etc.)
Fastest and cheapest to launch, with proven checkout and a big app ecosystem. The trade-offs: monthly fees, transaction cuts, per-app costs, and limits on how far you can customise. Great for standard stores.
Custom / headless
A custom e-commerce build gives you exactly the checkout, pricing logic, integrations and performance you want, with no per-transaction platform tax and full ownership. It costs more upfront and suits businesses whose operations or scale don’t fit a template.
Indicative cost by store type
| Store type | Indicative cost | Best for |
|---|---|---|
| Starter store | $1,500 – $5,000 | Small catalogue, standard checkout, templated design. |
| Custom business store | $5,000 – $20,000 | Bespoke design, larger catalogue, a few integrations. |
| Custom / headless | $20,000 – $60,000+ | Complex logic, ERP/accounting integration, high performance. |
| Marketplace | $12,000 – $180,000+ | Multiple sellers, split payments — see marketplace development. |
The running costs people forget
The build is one number; running the store is another. Budget for:
- Hosting and domain (small, but ongoing).
- Payment-gateway and transaction fees (a percentage of every sale).
- Platform subscription and paid apps/plugins, if you’re on a platform.
- Maintenance, security updates and support after launch.
- Marketing — a store with no traffic makes no sales.
Over a few years, platform transaction fees on a high-volume store can exceed the one-time cost of a custom build — which is exactly when custom starts paying for itself.
How to get an accurate quote
A trustworthy number comes from a short conversation: how many products, which payment methods, what needs to integrate (accounting, inventory, shipping), and how custom the design should be. With that, a good partner gives you a fixed price — not a guess. If you also need a marketing website around the store, factor that in too.
