Ecommerce development

Your store, looked after
whichever platform it’s on.

Magento and Shopify development from UK developers who stay responsible for your store after launch, and tell you honestly what it needs.

Illustration: a store’s product page. Moving the coral slash across it reveals what the developers look after underneath, on Magento or Shopify: the theme, platform patches, page speed, image optimisation, stock and price sync with the ERP, and the checkout.

Built for you

Bespoke
back on the table.

AI now lets our developers build bespoke features faster than ever. On Magento you own the code, so the features you’ve always wanted are back within budget.

And because AI makes our developers faster, you get more for the hours on your plan: the output goes up, and your hours stay the same.

  • Product finders
  • Configurators
  • Smarter search
  • Delivery scheduling

Where to start

Specialists
for the job in hand.

Support plans

Keep it running. Keep it moving.

12, 18 or 24+ hours a month, with monitoring, zero-downtime deployment, monthly goal planning and the full AI Core plan.

Magento / Agency rescue

Current agency not working out?

A three-month rescue package: the latest Magento upgrade, critical performance fixes and free onboarding. No commitment after that.

Magento / Hyvä & Breeze

A faster frontend, built to last.

Hyvä and Breeze themes that make Magento quick on mobile, from a Hyvä Partner.

Shopify / Development

Shopify, looked after.

Themes, apps, custom integrations and storefront performance, cared for the way Shopify works.

Being pushed to replatform?

We help you make the right platform decision
and support you whichever way you go.

Shopify isn’t right for everyone, and neither is Magento. Replatforming should start with a business case, not because someone at a conference said so.

Stay on Magento if…

  • Your requirements need deep customisation
  • Complex B2B, pricing or catalogue logic is central
  • You want full control of code and hosting
  • You want features no app offers

Consider Shopify if…

  • Your custom code mostly recreates standard features
  • You’d rather not own platform maintenance
  • The total cost case stacks up, apps included

Not sure?

That’s the most sensible answer we hear all week.

Before we put the kettle on

Fair questions
Straight answers.

New to outer/edge? Start here.

Do you only work on Magento?

No. Magento and Adobe Commerce are where we made our name, and we also develop and look after Shopify stores. Each platform gets care that fits how it works.

Should we replatform?

Maybe, maybe not. We’ll look at your integrations, custom functionality and costs, give you an honest business case, and support you whichever way you go.

Can you take over from our current agency?

Yes. Our Agency Rescue package steadies a Magento store in three months, with free onboarding and no commitment after that.

What’s included in a support plan?

Live support, monitoring, zero-downtime deployment, unlimited staging, monthly goal planning, yearly reviews, security patches and the full AI Core plan. Plans come in 12, 18 or 24+ hours a month.

Who will we actually talk to?

Developers. Everyone on our team writes code, including the MD. We’re UK-based and in-house, so you’ll get a truly personal relationship.
