Bespoke Shopify Development

For businesses that have outgrown off-the-shelf themes and app stacks. We build Shopify stores and integrations that fit how you actually operate.

What we do differently: Every project is handled by our UK-based team from discovery through to launch. No templates, no offshore, no bloated plugin stacks. Built around your workflows, not the other way around.

Custom Shopify development without the unnecessary complexity

Most Shopify problems are not Shopify problems. They are the result of a setup that was never designed for how the business actually works. We fix the foundations.

🏗️

Custom theme development

Built for your brand, your catalogue structure, and your customers - not adapted from a template that nearly fits.

🔗

Integrations and API work

Shopify connected to your accountancy platform, ERP, stock system, or fulfilment provider. Accurate, automated, and reliable.

Performance and speed

Slow stores lose sales. We strip out what does not need to be there and rebuild performance as a requirement, not an afterthought.

🔧

App reduction and consolidation

If your store is held together with ten apps, we can consolidate the core functionality into the theme itself and remove the dependencies.

🛒

Checkout and conversion work

Variants, upsells, custom product pages, abandoned checkout flows. Built properly, not patched together with plugins.

📈

Ongoing development partnership

We work with most clients on a continuing basis after launch. The store grows, your requirements change, and we are still there.

🔀

Platform migrations

Moving from Magento, Visualsoft or WooCommerce? We handle the entire migration - data, SEO redirects, custom functionality - so you keep trading while we rebuild properly.

Shopify Plus development

Custom checkout, advanced scripting and bespoke functionality that only Shopify Plus unlocks. Built for businesses that have genuinely outgrown standard Shopify.

Shopify development done by real people who understand the brief

We do not pass projects down a chain of account managers. Rob, Jason, and the team are directly involved from the first conversation through to go-live.

1

Discovery

We sit down with you and map out how your business actually runs: your current systems, the gaps, and what a well-built solution would look like. No proposals before we understand the problem.

2

Design

We shape a solution around your workflows, not around what is easiest for us to build. From the front end through to the back-end architecture, it is designed to streamline how your team works day to day.

3

Build

Every line of code is written by our UK-based team. No subcontracting, no offshore handoffs. Full transparency at every stage and no black boxes.

4

Launch and beyond

We handle rollout, training, and onboarding. And we are still available months later when you need changes, support, or the next phase of development.

Is your Shopify store too slow?

Slow stores lose customers before they convert. We diagnose what is dragging your performance down and fix it - so your store loads faster, ranks better, and converts more.

What Our Clients Say About Us

“After ongoing issues and delays with our previous developers, we brought in Rob & Jason at Dev Partners to take over all our websites and bespoke software. What a breath of fresh air - they were fully focused, with excellent pre-launch designs and clear communication throughout. Highly recommended to anyone.”

What makes us different to most Shopify agencies

There are a lot of Shopify developers. Here is what actually distinguishes the way we work.

The short version

We are a small team and that is the point

When you work with Dev Partners, you are talking directly to the people building your store. Rob and Jason are involved in every project. There is no account management layer, no junior developer handed a brief they did not write, and no offshore team you never meet.

That means faster decisions, cleaner communication, and a team that actually understands what you need - because they asked the questions themselves.

  • Fully UK-based team - no offshore development
  • Rob and Jason directly involved in every project from start to finish
  • No cookie-cutter templates - every build is designed for your specific setup
  • Ongoing relationship after launch, not just a handoff
  • Direct support from the people who built your store
  • Shopify Select Partner
