June 7, 2026. If your Shopify store still runs custom checkout logic through Shopify Scripts, the countdown is real and short. Per Shopify's developer changelog, all Scripts stop executing on June 30, 2026, just over three weeks away. Anything you built on Scripts, custom discounts, shipping rules, or payment gating, simply stops working that day unless you have migrated.
The key dates and facts
- April 15, 2026: editing and publishing new Shopify Scripts is already disabled, so you cannot patch your way out after that point.
- June 30, 2026: all Shopify Scripts cease to execute entirely. This is the hard cutoff.
- The replacement is Shopify Functions, which Shopify has extended to cover discounts, shipping, and payments, the same areas merchants previously handled with Scripts.
- Shopify provides a Scripts customizations report that lists exactly which of your current customizations need to move, so you are not guessing.
- Scripts and Functions can run side by side during the transition, so you can migrate one piece at a time rather than in a single risky cutover.
What it means for operators
This mostly hits Shopify Plus merchants with custom checkout behavior: tiered or bundle discounts, conditional shipping, and rules that hide or reorder payment methods. The failure mode is quiet and expensive, because checkout keeps loading but your custom logic is gone, so a discount that should apply does not, or a shipping rule that should block an option no longer does. You may not notice until revenue or margin slips. The fix is straightforward but not instant: run the customizations report, map each Script to a Function or a vetted public app, and test in a staging environment before the deadline. Leave buffer, because the last weeks of June will be crowded with merchants doing the same thing.
If you would rather not gamble your checkout on a deadline, our team migrates Scripts to Functions cleanly. See our Shopify expert and Shopify apps services, part of how we support e-commerce stores. Primary source: the Shopify developer changelog; migration steps in the Shopify Help Center.
Frequently Asked Questions
All Shopify Scripts cease to execute on June 30, 2026. Editing and publishing new Scripts was already turned off on April 15, 2026, so existing Scripts cannot be changed before the final cutoff.
Shopify Functions, which Shopify has expanded to handle discounts, shipping, and payments. Custom logic you previously ran as a Script is rebuilt as a Function or moved to a vetted public app.
Your custom checkout logic disappears on June 30. Checkout still works, but custom discounts, shipping rules, and payment gating stop applying, which can quietly cost revenue or margin until someone notices.
Use Shopify's Scripts customizations report. It lists your current customizations and flags which ones can move to Functions or public apps, so you can plan the migration without guessing.
