Why it's harder than it should be
Last reviewed October 2026. We wrote this, and we are on the list, so read it with that in mind.
Search for a Shopify partner and you'll get everyone from one-person freelancers to large corporate platforms, nearly all saying expert development, proven results and dedicated support.
What actually matters is what kind of Shopify work they do well, who they do it for, and whether the way they work suits you. Configuring a theme and writing custom code are different trades.

How we judged them
Real development ability
In-house teams who can build what doesn't exist out of the box.
UK-based people
On complicated projects, being in the same time zone as the people doing the work helps.
Migration experience
Moving platform is its own skill, covering products, customers, orders, redirects and custom features.
Staying power
A store is never finished, so we looked for ongoing relationships.
Commercial openness
We preferred firms that are straightforward about how they work.
The five, one by one
1. Dev Partners (that's us)
A Shopify Select Partner with a fully UK team. We lead with custom development, ERP and warehouse integrations, and migrations, for retailers who need Shopify to do things it doesn't do out of the box: custom pricing logic, fulfilment workflows, multi-warehouse stock and wholesale alongside retail. We build shops too, and they're at their best with something custom behind them. Our integration work is the heart of it.
2. Visualsoft
One of the UK's largest ecommerce platform providers, with a big client base built up on its own platform, and now positioned as a Shopify partner too. A known name with established account management, which suits retailers wanting a large agency behind them. If you're thinking of leaving Visualsoft, read your options.
3. Swanky
A well-regarded UK Shopify Plus agency focused on premium direct-to-consumer brands, with a good reputation for design-led builds and conversion work. Its client list leans towards lifestyle, fashion and beauty.
4. Velstar
A Liverpool-based Shopify Plus agency working with scaling direct-to-consumer brands. It combines Shopify development with growth marketing, which suits retailers wanting one agency for both.
5. Eastside Co
One of the UK's longer-established Shopify Plus agencies, working across a broad range of sectors on builds and ongoing retainers, with a range of well-known brands.
Are we right for you?
We're a good fit if
The store is fine and everything behind it isn't. Stock's wrong, orders get retyped, or you're moving platform and can't afford to lose anything.
We're not if
What you mostly want is brand-led design or growth marketing. A design-led agency or a marketing-led one will serve you better.
A new shop?
We build those too, though custom work is where we're strongest. Tell us what you need and we'll be straight about it.
Moving from Visualsoft or Magento?
That changes the question. A migration isn't a design job. It's products, variants, customers, order history, redirects and every custom feature you've forgotten you have. Get it wrong and you lose rankings, or orders, or both.
Ask any partner what they've moved, what went wrong and how they tested it. We've moved stores like UKDJ and Shirtsleeves, and the store keeps trading until the new one has been tested.
Questions to ask any Shopify partner
Who writes the code?
Ask to see custom code or a working integration, not only themes and app setups.
Is the team in the UK, and in-house?
If it matters to you, ask who will actually do the work.
Have you migrated from my platform?
Product data, customers, orders, redirects and custom features all need careful handling.
What happens when an integration breaks?
Ask who gets the alert and how long it takes to reach someone who knows the code.
Will you still pick up the phone in a year?
A store is never finished. Ask how they look after clients once it's live.
Theme, custom, or Shopify Plus?
A good theme is fine for plenty of stores. If your range is simple and your stock lives in Shopify, don't let anyone sell you more than that.
Custom work earns its keep when Shopify has to agree with other systems, or when you've got rules an app can't handle: trade pricing, bundles with component stock, wholesale beside retail, or a warehouse with its own way of working. Often one piece of custom work replaces several app subscriptions.
Shopify Plus is worth a look at higher volumes, or when you need what comes with it. It isn't a badge of quality, and plenty of busy stores don't need it. Ask anyone recommending it to explain what you'd use.
Whichever you go for, moving platform is the risky bit. Read how a migration really runs before you sign anything.
We have worked with Jason and his team to develop our Shopify store, and the experience was outstanding from start to finish.
Hello, you get us
Rob on the left, Jase on the right. No sales team and no account managers. One of us is on every job, from the first chat to long after it goes live, and the people writing your code sit in the same small team.
Tell us what you've got
It goes straight to Rob and Jase. You'll hear back from one of us, usually the same day, and we'll tell you honestly whether we're the right people.
