Shopify Scripts stopped executing on June 30, 2026. Shopify had already blocked editing and publishing of Scripts on April 15, 2026, and it now points merchants to Shopify Functions for custom discount, shipping and payment logic. Any store that relied on Scripts and did not migrate lost that custom behavior at checkout. Merchants who are unsure whether they were affected should check now, because Shopify's announcements offer no way to restore Scripts.
What happened
Shopify set out the timeline in its merchant changelog on March 12, 2026 and repeated it in the developer changelog on April 9, 2026:
| Date | Change |
|---|---|
| April 15, 2026 | Editing and publishing new Shopify Scripts no longer possible |
| June 30, 2026 | All Shopify Scripts stop executing entirely |
Shopify says Functions now provide the capabilities for discounts, shipping and payments that merchants previously built with Scripts. It also offers a Scripts customizations report in the admin to help merchants identify which customizations can move to Shopify Functions or to public apps, and a Help Center migration guide.
The three kinds of Scripts that merchants could write map to three areas where Functions now customize checkout:
| Former Script type | Where the logic now belongs |
|---|---|
| Line item scripts (pricing and discounts) | Discount functions or discount apps |
| Shipping scripts | Delivery customization functions or apps |
| Payment scripts | Payment customization functions or apps |
Shopify's Functions documentation explains that function logic can be written in any language that compiles to WebAssembly, with Rust and JavaScript recommended, and that Shopify invokes functions itself at defined points in the customer journey rather than through a URL.
Why it matters for merchants hiring IT firms
Scripts were typically used for rules such as tiered or volume discounts, bundle pricing, free shipping thresholds, hiding shipping or payment methods for certain orders, and wholesale pricing. If any of that logic was not rebuilt, customers may now see different prices, shipping options or payment choices than you intended. That can affect margins and conversion without any visible error message, so the problem can go unnoticed for weeks.
If you are hiring a Shopify development company to fix or rebuild this logic, ask:
- whether an existing public app covers the rule, or whether a custom Function is needed;
- how they will test edge cases such as stacked discounts, mixed carts and international orders;
- who will host, update and support the app that contains the Function after launch.
Why it matters for IT firms
For agencies, Functions are a different development model from Scripts. The work now involves building and deploying apps that contain Functions, testing them against Shopify's discount, delivery and payment customization points, and documenting them so clients understand what runs at checkout. Firms that offer ecommerce development should audit client stores for any remaining gaps and offer a post-migration review, since some merchants may only notice changes when they compare monthly reports.
What to do next
- Open the Scripts customizations report in your Shopify admin, or review old Script code from your records.
- Compare current checkout behavior with your intended discount, shipping and payment rules, using test orders.
- Decide for each rule whether a public app or a custom Function is the better fit.
- Monitor average order value, discount usage and payment method mix for changes since June 30.
