Once a store outgrows standard Shopify, the requirements shift fast. Checkout customization, wholesale channels, multi-currency expansion, automation across warehouse and CRM systems, Shopify Plus is built for merchants operating at real volume, and building at that level takes a genuinely different skill set than a standard theme project.
The UK has a strong bench of Shopify Plus specialists, ranging from boutique design-led studios to agencies handling enterprise retail migrations. Here’s a shortlist worth working through.

What to Check Before You Hire
Since Shopify Plus projects are more technical than regular builds, due diligence is even more necessary. So, before hiring a partner, it’s necessary to check.
- Shopify Plus Partner status specifically – not just standard Shopify Partner status, since Plus requires additional certification.
- Migration experience – if you’re moving from another platform, ask for specific examples of Plus migrations they’ve handled, not just new builds.
- Checkout Extensibility experience – Plus’s biggest advantage is checkout customization; confirm hands-on experience with Checkout Extensibility rather than legacy checkout.liquid work.
- Post-launch support and SLAs – enterprise stores need faster response times when something breaks; confirm what support tier is actually included.
