Shopify and Shopify Plus development: custom themes, apps, headless builds and migrations.

What you get
Everything it takes.
Six things included when we take this on — scoped to your business, never padded out.
Apps & integrations
Private and public apps — plus careful choice of third-party apps, so you don't pay for ten tools that slow the store.
Shopify Plus & headless
Checkout extensibility, Shopify Functions, B2B and Hydrogen storefronts for brands that need more control.
Store migrations
From WooCommerce, Magento, BigCommerce or custom platforms, with products, customers, orders and SEO carried over.
Markets & international
Multiple currencies, languages and duties configured with Shopify Markets, so international buyers see local prices.
Speed & theme audit
An audit of app scripts, images and Liquid performance with a prioritised fix list — often the fastest revenue win.
How we approach it
Step by step.
Specific to Shopify development — and at every step you'll see something real, not a status update.
- 01
Store audit
We review your theme, apps, analytics and checkout funnel to find what's costing you sales.
What you seeAn audit with quick wins you can ship this month. - 02
Design the sections
The storefront is designed as a library of sections, so new campaigns don't need a developer.
What you seeDesigns for key templates, plus the section library. - 03
Build & integrate
Theme, apps, metafields and integrations built on a development store and reviewed weekly.
What you seeA preview link you can browse and test on your own phone. - 04
Launch & grow
Theme published, redirects checked, speed verified — then the CRO roadmap begins.
What you seeA launch report and the first month of test results.
Honest fit
Is this right for you?
Good fit if…
- You're on Shopify and the theme or app stack is holding you back.
- You're moving to Shopify from another platform and want to do it once, properly.
- You sell internationally or need Plus features such as B2B, Functions or checkout customisation.
Not the right fit if…
- You're happy with a standard theme and need minor tweaks — a Shopify freelancer is a better fit.
- You need ERP-driven B2B pricing across thousands of accounts; Magento may suit better, and we'll compare.

Ways of working
How we work together.
Every project is scoped on its own terms — we'll agree the shape, the pace and the team with you before anything starts.
Fixed-scope project
A defined deliverable, a timeline and a single agreed fee before we start. Changes go through a simple change note, never a surprise invoice.
Best forNew themes, migrations and Plus builds.
Monthly retainer
A standing team and a set number of hours or outcomes each month, reviewed together and adjusted as priorities shift.
Best forTrading support and CRO.
Sprint
One or two focused weeks on a single problem, with a clear goal on day one and a working result on the last day.
Best forA speed audit or a custom app.

Only if you need its features — checkout customisation, B2B, automation or very high order volumes. Many brands grow happily on standard plans; we'll tell you when Plus pays for itself.
On Plus, yes — through checkout extensibility and Shopify Functions: upsells, custom fields, delivery rules and discounts. Other plans allow less, and we'll be clear about the limits.
A well-built theme suits most brands and costs less to run. Headless with Hydrogen makes sense for very content-rich stores, unusual experiences or complex multi-brand setups.
Not if the migration is planned. We map URLs, keep metadata and structured data, and monitor rankings closely after launch.
When they overlap or slow the store down. We audit every app for cost, speed and value; clients often remove a third of them with no loss of features.
