The short answer
A custom ecommerce website usually costs $900 to $10,000 for a custom front end on a commerce platform with a standard catalogue, $10,000 to $50,000 for a headless store with product rules, several markets or links to your own systems, and $50,000 or more for a fully custom build. At Enthros a custom store starts at $900 and goes live in 7 to 10 weeks.

What does a custom ecommerce website cost?
As a rough guide, based on the quotes clients show us:
- A custom front end on a commerce platform, with a standard catalogue and checkout: about $900 to $10,000
- A headless store with product rules, subscriptions, several markets or links to stock and accounting: about $10,000 to $50,000
- A fully custom store with its own back office, configurators and complex pricing: $50,000 and up
What changes the price?
- Catalogue size and product rules: made to measure, bundles or prices set by size add logic and testing
- Markets: each extra currency, language and tax setup adds work
- Links to your systems: stock, shipping, accounting and email tools
- Moving an existing store: products, customers, orders and redirects so you keep your search rankings
Custom store or Shopify theme?
A Shopify store with a custom theme suits most brands and costs less to build and run. A custom or headless store makes sense when products follow rules no theme handles, traffic peaks are large, or the shopping experience itself is part of the brand. If a theme with a few apps covers how you sell, start there.
What else should you budget for?
- Platform fees: a monthly plan if the store runs on a commerce platform such as Shopify
- Hosting for the front end: often free to about $20 a month for a small store, more for heavy traffic
- Payment fees: a small percentage of each order, set by your payment provider
- Upkeep: updates, new features and checks after platform changes
