(01) The short answer

What is ecommerce development?

Ecommerce development is the design and build of an online storefront — merchandising, product discovery, and checkout — along with the performance work that keeps it fast under real traffic. Cortexley builds on Shopify, Shopify Plus, WooCommerce, and headless stacks, and has shipped live storefronts for fragrance, haircare, and eyewear brands.

(02) Cost & timeline

How much does ecommerce development cost?

A custom Shopify store typically costs £2,000–£7,000 and takes 4–8 weeks. Shopify Plus builds with custom checkout logic or platform migrations typically cost £8,000–£20,000, and fully headless storefronts start around £15,000.

Notes From Building Botanica's Storefront

A behind-the-scenes look at how we built a Shopify storefront for a hard-water haircare brand that had to sell the problem before the product.

(07) Questions

Before you ask.

Both. We can extend a well-built existing theme or start from a blank canvas depending on your timeline and how far your current setup is from where you need to be.

Yes — we've handled migrations from Magento, custom PHP carts, and BigCommerce, preserving SEO equity and historical order data.

Most rebuilds land between 6 and 12 weeks depending on catalog complexity, custom checkout requirements, and third-party integrations.

We keep design and engineering under one team, so your storefront doesn't get diluted through handoffs — merchandising flexibility and performance work are built in from day one, not bolted on after launch.

Shopify is where most of our storefront work lands. Our Shopify developers have shipped a custom Prestige theme build for a fragrance launch, a virtual try-on integration for prescription eyewear, and a cash-on-delivery checkout flow for the Pakistani market — all on live stores. We also build headless and WooCommerce when the roadmap genuinely calls for it.
