Ecommerce website development that grew online orders 2.4x
A retailer's ageing online store crawled on phones and fell over during its biggest sales. We rebuilt it as a fast, cloud hosted store that stays up when the crowds arrive. Within a year of launch, online orders had grown 2.4 times.

The problem: a store that could not keep up
The store ran on an older platform the business had outgrown. Most shoppers came in on their phones, and on a phone the pages loaded slowly. In the busiest sales, when traffic jumped, checkout slowed to a crawl or stopped working altogether, on the very days the retailer expected to sell the most.
Changing anything was slow too. Every new banner or promotion needed a developer, so the marketing team waited days for simple updates. The stock levels shown on the site also drifted away from what the warehouse actually held, and some orders had to be cancelled.
How we worked phase by phase
Project phases in months
Daily trading carried on as normal while data moved across in rehearsed batches.
How the new ecommerce website works
How the online store fits together
We used what's called a headless commerce design. The shop window your customers see is kept separate from the engine behind it, which handles products, prices, stock, orders and payments. The two talk through APIs (application programming interfaces, the standard way one system asks another for data). That means the marketing team can publish new pages without going anywhere near the checkout.
When traffic rises, Amazon Web Services (AWS) adds servers by itself. Orders go straight through to the warehouse, so nobody has to type them in again.
Protecting search rankings
Search engines and shoppers' bookmarks still pointed at the old product and category addresses. We set up permanent redirects so each old address sends visitors and search engines to its new page, and we checked the site in search tools before and after launch.
Security and quality checks
Card details never touch the store: they stay with the payment provider. Staff only get the admin access their role needs. Before any change reaches shoppers, it passes automated tests in a CI/CD pipeline (an automated process that tests and releases each update).
Results after launch
Online orders (before = 100)
Online orders grew 2.4 times within a year of launch.
What changed for the retailer
- Faster pages. Product pages now load quickly, whether shoppers are on a phone or a laptop.
- Steady at peak. Since launch, the store has stayed up through every peak trading period.
- Marketing in control. A promotion someone suggests on Monday can be live the same week.
What we learned
Speed wasn't the only thing that moved sales. Letting the marketing team change the store themselves did as much for orders as the faster pages did.
