Shopify Development
Theme customisation, custom features and migrations for shops that run on Shopify
Shopify work that fits how you actually sell
Whoooop Ltd builds and customises Shopify stores. If you've already settled on Shopify — or you're running one and it isn't quite doing what you need — this is the developer side of that: editing the theme, adding the bits the platform doesn't give you out of the box, and wiring the shop into the rest of your business. We've worked in full-stack development for more than 15 years, a fair chunk of it on busy e-commerce, so the focus is a store that takes the order cleanly rather than one that just looks the part.
What we do on Shopify
Theme customisation
Changes to an existing theme or a build from a base one — layout, sections and Liquid templates adjusted to match how you want the shop to read, not whatever the demo shipped with.
Custom features
The functionality a stock theme leaves out: product options that don't fit a simple variant, bundles, trade pricing, or a checkout step pared back to what the customer needs to fill in.
Apps and integrations
Picking the right apps instead of stacking ten that slow the store down, and connecting Shopify to accounting, shipping and email so orders flow through without being re-keyed.
Moving to Shopify
Migrating from another platform with your products, customers and URLs carried across, and redirects in place so the search rankings you've built don't reset to zero.
Speed and Core Web Vitals
Trimming the theme, images and third-party scripts that drag a store's load time down, because a slow product page loses the sale before the customer reaches the cart.
Ongoing support
Inherited a store and lost the developer who set it up? We can take it on, fix what's broken and keep it maintained rather than leaving you stuck.
When Shopify is the right call — and when it isn't
Most shops are well served by Shopify. It handles the hosting, the security and the payment compliance, copes with a busy sale day, and you can run it day to day without a developer on standby. Where it starts to fight you is unusual pricing, deep customisation or fulfilment that doesn't match how the platform assumes an order behaves. At that point a bespoke build can be the better answer — there's more on that, and on choosing between the two, on our e-commerce web development page. And if what you're really describing is software with a shop attached rather than a shop, our web application development page is the more honest starting point.
Keeping a Shopify store quick when it's busy
A promotion, a press mention or a seasonal rush can land more traffic on a store in an hour than it usually sees in a week. Shopify carries the hosting load, but the theme is still yours to keep lean — every extra app, render- blocking script and oversized image adds to what a phone has to download before someone can buy. We test on real devices and cut that weight back, so the shop stays quick on the day it most needs to.
