We design and build Shopify shops, from a first store to a full rebuild on Shopify Plus. Every theme is built for the shop it runs, so it's fast on a phone, easy for your team to run and doesn't lean on a pile of monthly apps.



Who it’s for
Shopify shops that are slow on mobile, or paying for apps that theme code could replace.
Brands moving to Shopify from WooCommerce, Magento or WordPress, where rankings and order history have to come across intact.
Shops selling to trade as well as the public, or in more than one country.
Brands launching a new shop that need the design and the build from one team.
When it isn’t a fit
Businesses turning over less than £2m rarely need Shopify Plus. Standard Shopify is quicker to build, cheaper to run and covers nearly everything a shop of that size needs.
What’s included
We build custom Shopify themes rather than reskinning a bought one. That keeps the code lean, which is why our rebuilds get faster: at Gieves & Hawkes the mobile speed score went from 64 to 85, and eight apps were replaced with theme code, saving £300 a month.
Where Shopify can't do something, we build it as a custom Shopify app. Shops we look after include Fun Cases, Sublishop, ValuePet and Twisted Tailor.
Includes
Custom Shopify themes, Shopify Plus, Shopify Markets, B2B and wholesale, Migrations to Shopify, Theme speed work, App audits, Custom Shopify apps, Klaviyo, SEO foundations.
Which platform
Suits most online shops. It's quick to launch, easy to run and handles high order volumes.
For businesses that need B2B and wholesale, several regions, a custom checkout or Launchpad.
Every build is responsive, with the checkout designed for phones, the catalogue for tablets and the homepage for large screens.
Shopify PartnerMost Shopify rebuilds take 6 to 10 weeks from kick-off to launch, and heavier custom work 10 to 12. We fix the timeline at the end of discovery.
One week
We agree the scope, the goals and whether standard Shopify or Shopify Plus is the right fit.
We design the page templates and the product and checkout journeys. You sign off the designs before we start building.
We build the theme, move the products, customers and orders, and connect the apps you keep.
Redirects from every old URL, analytics, payments and shipping, all tested before the shop goes live.
Optional
A Shopify care plan for updates, speed and new features, with no lock-in.
Measured results from Shopify builds and rebuilds.
Gieves & Hawkes mobile speed score out of 100, up from 64 before the rebuild.
Sublishop sales growth in the three months after relaunch.
ValuePet average order value the week after launch.
