Shopify Development

Shopify development for stores that need more than a theme

Custom checkout, configurators, B2B and retail on one stack. If the build is the hard part, that's the work we take.

When We Can Help

The theme stopped being the answer a while ago.

  1. /01

    Your checkout needs rules Shopify lacks

    Tiered pricing, order minimums, B2B terms or bundle logic that apps only half cover. We build the rules into checkout, so they hold on every order.

  2. /02

    One store must serve wholesale and retail

    Wholesale buyers need their own prices, terms and catalogue, and retail customers shouldn't see any of it. We set up one store that serves both, without a second backend.

  3. /03

    Your product needs configuring to sell

    Options, dependencies and prices that change with every choice. We build configurators that show buyers exactly what they're ordering and pass production-ready data with the order.

How We Build

From scoping the build to support after launch.

  1. Scope & Estimate

    We work through what the build actually needs and what it will cost before anyone writes code.

  2. Plan & Architecture

    We decide the data model, the integrations and where custom code is justified rather than convenient.

  3. Build & Review

    We develop in reviewable stages so you see the store working before launch, not a demo at the end.

  4. Launch & Support

    We ship it, watch it under real traffic and stay on it after the launch rather than handing over a login.

Numbers that matter

FAQ

Questions
we get asked

Can you customise Shopify checkout?

Yes, on Shopify Plus. Checkout validation, discount logic and delivery rules are built with Shopify Functions and checkout extensions rather than workarounds. On standard plans the options are much narrower, and we will tell you which of your requirements are not possible before you commit to anything.

Do we need Shopify Plus?

Only for specific things. Plus is required for customising the checkout steps themselves, more than three B2B catalogs and higher API limits; basic B2B (company accounts, price lists, net terms) now works on Basic, Grow and Advanced too. If none of your requirements need those, a standard plan is usually enough and we will say so rather than sell you the upgrade.

Can you build a product configurator on Shopify?

Yes, and we have. A configurator built into the storefront handles options, dependencies and made-to-order ranges that variants alone cannot express. Prime EVA is the example: a custom configurator running inside their Shopify store rather than as a bolted-on app.

Can one store serve wholesale and retail?

Yes. Shopify B2B runs company accounts, price lists and payment terms alongside your retail catalogue, so you are not maintaining two stores that drift apart. We have built this, though that client's work is not public.

When does headless Shopify make sense?

Less often than it gets recommended. Headless is worth it when you need a front end Shopify's theme layer cannot deliver, or when the storefront serves more than one channel. It costs more to build and more to maintain, so if a well-built theme does the job we will tell you that instead.

Can you work with our existing theme, or is it a rebuild?

Usually your existing theme. We audit what it can carry, extend it where that holds up, and only recommend a rebuild when the theme is fighting what you need. A rebuild you did not need is the most expensive thing on a Shopify project.

How long does a custom Shopify build take?

Most builds run 4 to 16 weeks, depending on the integrations and how much is custom rather than configured. We scope and estimate before writing code, so the timeline is agreed at the start.

What happens after launch?

We stay on it. We watch the store under real traffic, fix what surfaces in the first weeks, and keep it working through Shopify's API version changes. Handing over a login and disappearing is where most of the problems we get called in to fix started.

Have a build that needs more than a theme?

Tell us what the store has to do and we'll tell you how we would build it.
