What the end of Checkout Scripts means for your store
Shopify is retiring Checkout Scripts in favour of Functions and checkout UI extensions. Here is what changes, and what to do before the deadline.
If your store still runs Checkout Scripts, they are living on borrowed time. Shopify is moving checkout customization onto two supported technologies: Shopify Functions for logic, and checkout UI extensions for content. The old checkout.liquid and Script Editor approach is on the way out.
Why Shopify is making the change
The new stack runs on Shopify’s own infrastructure. It is faster, safer, and it survives platform updates instead of breaking on them. For merchants, the headline is reliability: your checkout logic stops being a liability every time Shopify ships a change.
What actually needs to move
Anything you built in the Script Editor. Discount logic, payment method rules, delivery customization, and any content injected into the old checkout. Each of these has a home in the new model, but the migration is not automatic. The logic has to be rebuilt and tested against real carts.
What to do now
Audit what you depend on today, rebuild it as Functions and extensions, and test the new flow before you switch. Do it now, while there is time to get it right, rather than at the deadline.
If you want a hand with the audit, that is exactly the work we do.
