Migrating your Shopify store to a new developer: what you need to know

Why businesses switch Shopify developers

A partnership with an agency or developer doesn't always turn out as you'd hoped. Slow responses, unclear invoices, lack of strategic input — these are signs that a switch is needed. Good news: your Shopify store remains yours, and switching is simpler than many business owners think.

How does a migration work technically?

Shopify works with a permission system for collaborators. As the store owner, you control who gets access and with what rights. You add a new developer as a Staff member, after which they get access to themes, settings, and apps. You don't need to ask your previous developer for permission — you simply revoke their access once the handover is complete.

Custom code — such as theme modifications or private apps — lives in your Shopify environment and remains accessible. Sometimes there's external documentation or separate staging environments; you can request those from the previous party. In practice, outdated custom code often causes more problems than it solves, and rebuilding is sometimes more efficient than repairing.

What to expect from a new partnership?

A good developer starts with a thorough audit: which apps are you running, what modifications have been made, what works well and what's fragile? That initial exploration often takes one to two weeks. After that, you receive one concrete proposal with scope, timeline, and fixed price for the adjustments or improvements needed.

At Kattenberg 118 Studio, I deliberately choose the platform that fits, even if that's not Shopify. I've guided clients to Ghost when that was a better fit for their content model, and I've built fully custom solutions where Shopify was too cumbersome or too expensive. No sales talk, no commercial interest in one platform — just honest advice from fifteen years of experience as an entrepreneur.

Concrete steps for a smooth transition

• Week 1–2: New developer receives Staff access, conducts an audit, and asks questions about your current setup and wishes.
• Week 2–3: You receive a proposal with clear scope and fixed price. The actual work only starts after approval.
• During migration: Good coordination about who does what. Some things (such as DNS or payment providers) remain your responsibility; the developer handles technology and implementation.
• After delivery: Clear documentation and handover, so you're not dependent on one person again.

When is it time to switch?

If you're waiting weeks for a simple modification, if invoices are unclear, or if you feel stuck, it's time for a conversation. A good developer thinks along about the long term, guards your budget, and delivers transparently as agreed.
