Migrate from Custom to Shopify. Completely.
Built it in-house and now it is a millstone. We have migrated dozens of bespoke commerce stacks to Shopify.
Why leave Custom?
Your custom platform was a great idea in year one. By year five, it is the reason you cannot ship.
Engineering time spent on plumbing
Your devs maintain checkout instead of building features.
Hard to hire for a custom stack
Every new dev needs months to ramp.
No app ecosystem
Every integration is a custom build.
Fragile during traffic spikes
Black Friday is a fire drill.
No real merchant tooling
Marketing has to ask engineering for everything.
Compliance & PCI overhead
You audit it. You fix it. You pay for it.
What we move from Custom.

We built our own commerce stack in 2016. By 2024 it was the bottleneck of the entire company. StoreShifter moved us to Shopify Plus in 4 weeks. Our roadmap unlocked overnight.
Custom migration questions.
In 90% of cases, yes. We do a discovery phase first to confirm.
We recommend based on your team and use case. Standard is faster; Hydrogen is more flexible.
Rebuilt as Shopify apps, Flow workflows, or middleware (Celigo, MuleSoft).
Implemented via Shopify Functions and Checkout Extensibility.
Most custom migrations land in 3-6 weeks depending on complexity.
We always run parallel and only cut over once data and flows are 1:1 verified.
