Ecommerce Website DevelopmentEcommerce Website Development
Storefronts that convert — not just storefronts that exist.
We design and build ecommerce websites across Shopify, WooCommerce, and custom headless stacks — choosing the platform based on your catalog complexity and roadmap, not default.
(01) The short answer
What is ecommerce website development?
Ecommerce website development covers the build of an online store — product catalog, checkout, payment processing, and the performance work that keeps it converting under real traffic. Cortexley's ecommerce builds span Shopify and Shopify Plus for standard and high-growth retail, WooCommerce for content-heavy stores, and Next.js headless builds where the roadmap genuinely requires it.
(02) Cost & timeline
How much does ecommerce website development cost?
A custom ecommerce website on Shopify typically costs £2,000–£7,000 and takes 4–8 weeks to build and launch.

Before you ask.
Shopify is the safest default for product-focused retail — the hosted infrastructure, merchant-friendly admin, and app ecosystem handle most requirements without custom engineering. WooCommerce wins when the business is content-first and already on WordPress. A headless build is justified when the checkout logic or content model genuinely exceeds what Shopify Plus can handle — which is rarer than the hype suggests.
A Shopify build on a premium template with customisation: £1,500–£3,500. A fully custom Shopify theme from scratch: £3,500–£9,000. A Shopify Plus build with custom checkout and multiple integrations: £8,000–£20,000. A headless ecommerce build: £15,000–£40,000+. These are development costs — platform subscription, app fees, and hosting are additional.
Yes. We handle migrations from Magento, WooCommerce, BigCommerce, and custom carts — including product data, customer accounts, historical orders, and redirect mapping to preserve SEO equity. We've run migrations where the redirect mapping work took longer than the build itself.
