Shopify theme development
& customisation

There are two jobs hiding under one request. Some stores need a custom Shopify theme built from scratch; most just need theme customisation — targeted changes to a solid base. Merchants are often sold the first when they need the second, and end up with a theme only its author can maintain. We tell you which one you actually need before a line of Liquid is written.

Either way, we build it to be handed over: clean Shopify Liquid development, Online Store 2.0 sections and blocks, and content your team can edit without calling a developer. We hold client work to the same standard as Neroli, our own Shopify theme. Fixed pricing, no surprise costs.

The honest question first

Customisation or a custom build — which do you need?

Usually this one

Shopify theme customisation

Modifying an existing or premium theme is right when your base theme is close and you need specific changes: new sections, a redesigned product page, brand styling, or a feature it’s missing.

  • Faster to deliver
  • Lower cost
  • Proven, maintained base
When nothing fits

Custom Shopify theme development

Building from your design in Liquid is right when no template fits your merchandising, you need unusual functionality, or a distinctive brand experience is the point.

  • Total control
  • Built around your merchandising
  • More investment

If you’re not sure, that’s the conversation to have first. We’ll recommend the cheaper path when it does the job.

What’s included

Everything that goes into the build

  • Custom theme developmentFrom your design, built in Shopify Liquid.
  • Customisation of existing or premium themesDawn or any Online Store 2.0 theme.
  • Online Store 2.0 sections and blocksSo non-developers can rearrange pages in the theme editor.
  • Liquid development, metafields and app blocksFor dynamic, data-driven content.
  • Responsive, mobile-first buildTested across real devices.
  • Theme speed and Core Web Vitals workSo the design doesn’t cost you conversions.
  • Headless theme buildsWhen a storefront needs a decoupled front end rather than Liquid — Hydrogen or a custom stack.

Performance is part of the build — see theme speed and technical SEO.

Our standard

Built to be handed over

A theme is a codebase you’ll live in for years, so we build it to be maintained — by you, not just by us. Every layout is a 2.0 section with clear settings, the Liquid is commented, and content is editable in the theme editor. No going back to a developer to change a headline. If you ever move on from us, the next team can read it.

Your theme can’t do what the business needs

The template has hit its limit and every workaround makes it worse.

Weighing a custom build against a premium template

You want a straight answer on which is right, not an upsell.

Every small change needs a developer

We hand back control, so your team edits content without a ticket.

Theme development — FAQ

What merchants ask before commissioning a theme

Do I need a custom theme or just theme customisation?

Most stores need customisation — targeted changes to a strong base theme — not a full custom build. Choose a custom Shopify theme only when no template fits your merchandising or you need a distinctive brand experience. A good developer will recommend the cheaper path when it does the job.

How much does a custom Shopify theme cost?

Customising an existing theme costs far less than a full custom build. We quote fixed scope and fixed price per project, so you know the figure before we start — based on the pages and features you actually need.

Should I use a custom theme or a premium template?

A premium template is the better value when it already covers your merchandising and you only need styling and a few sections. Choose custom Shopify theme development when the template fights you on every page, or the brand experience is the differentiator.

What is Online Store 2.0?

Online Store 2.0 is Shopify’s theme architecture built on sections and blocks with JSON templates. It lets you add, remove and reorder content on any page from the theme editor — so your team can edit the store without touching code.

Can I edit the theme myself afterwards?

Yes. We build with 2.0 sections and clear settings so you can change content, layout and imagery in the theme editor. You only need a developer for new functionality, not everyday updates.

Will a new theme slow my store down?

It shouldn’t. We build mobile-first and optimise for Core Web Vitals, so a richer design doesn’t cost you speed or conversions. Performance is part of the build, not an afterthought.

Not sure which one you need?
