design and development, one team, one goal
We have been designing and building Shopify stores for over 12 years. In that time we have watched a lot of beautiful stores fail to sell, usually because the design was made for an awards page rather than a customer with a credit card. Our work starts from the other end: what makes this specific visitor buy?
That does not mean ugly stores. It means design and development run by one team, with conversion data in the room from the first wireframe to the last line of Liquid. The result is a store that looks like your brand and behaves like a salesperson.

Custom Functionality
Custom Liquid, metafields and metaobjects, and bespoke features when an app either doesn't exist or would slow the store down.
- 02
App Integration
Reviews, subscriptions, search, loyalty, ERP connections: integrated cleanly, with the unused script weight stripped out.
- 03
Performance Optimisation
Core Web Vitals, image and script discipline, and fast themes. Speed is a conversion factor, so we treat it as one.

Shopify Plus
Checkout extensibility, B2B features, Shopify Functions, and automation for higher-volume stores on Plus.
built to convert, not just look good
This is the difference between us and a generalist design agency. We also run conversion optimisation programmes, which means we know, from tested evidence rather than taste, which product page layouts sell, where trust signals belong, and what actually happens when you hide the add-to-cart button behind a scroll.
That evidence flows back into every build. Aesthetic choices still matter (your brand has to look like itself), but when a design decision and a conversion pattern collide, we tell you, show you the data, and let the numbers referee. Stores we design are built to be tested, so the design keeps improving after launch instead of being frozen at sign-off.
how a shopify project works
A typical build takes 8 to 14 weeks from kick-off to launch. Simpler theme customisations land sooner; complex Plus builds with integrations take longer. We would rather give you an accurate timeline up front than a flattering one that slips.
- 01
Discovery
We dig into your products, customers, analytics, and current store before anyone opens a design tool. If you have conversion data, it shapes the brief from day one.
- 02
Design
Design work in staged reviews, desktop and mobile together. Every significant layout decision comes with the reasoning attached, so sign-off is informed rather than instinctive.
- 03
Development
Clean, maintainable theme code built to Shopify best practice. You see progress on a staging store throughout, not a big reveal at the end.
- 04
QA
Testing across devices, browsers, and real purchase flows, including payment, shipping, and tax edge cases that only show up when someone actually buys.
- 05
Launch
A planned cutover with redirects, analytics, and rollback covered. Launch day should be boring, and we do the work to keep it that way.
who we build for
Established brands with existing revenue: B2C and B2B, in the UK and internationally, usually moving up from a template that has run out of road or replatforming onto Shopify. They have proof their product sells and want a store that stops being the bottleneck.
We are not the right fit for pre-revenue startups. A custom build is a poor first investment before product-market fit, and our pricing reflects senior people doing the work. If that is your stage, start with a good off-the-shelf theme and come back when it is creaking. We will happily point you in the right direction either way.
after launch
A new build is a starting point, not a result. The stores that outperform are the ones that keep testing and improving after launch, using real customer data the new design finally makes available.
That is why most of our build clients move onto the Conversion Growth Retainer after launch: a monthly programme of research, A/B testing, and development that compounds the value of the build instead of letting it age.
