Shopify Scripts are shut down: how discounts run now

What fell away with the shutdown

Shopify Scripts existed on Shopify Plus alone. Line item scripts acted on the items in the cart and could change prices and grant discounts, for example for volume tiers, bundle discounts or free items.

Shopify phased them out in two steps. From April 15, 2026, Scripts could no longer be edited or published again, and since June 30, 2026, they do not run at all. A store that did not migrate has not granted its old script discounts since that date.

The successor is called Shopify Functions. Functions come from apps. Public apps from the Shopify App Store that contain functions may be used by stores on every plan. Custom apps with their own functions are, according to Shopify, allowed for stores on Shopify Plus.

How to move discount scripts over to Hand-E Discounts

Take each old script by itself and translate its rule into a discount type. One rule becomes one discount.

1. For every script, write down in one sentence what it did, for example: 10% off from 5 pairs, 15% off from 10 pairs on the Socks collection.
2. Match that sentence to a discount type: Volume tiers, Cart value tiers, Bundle, Gift above cart value or Bulk codes.
3. Check how your script counted quantities and pick the matching counting mode in Volume tiers: each cart line on its own, all variants of a product together, or everything in scope together.
4. Rebuild the rule, and for Volume tiers and Bundle recalculate a typical cart in the cart preview.
5. Compare the result with an old order from the time when the script was running. Differences of a few cents can come from rounding.
6. Set the combinations. Discount functions run side by side and know nothing about each other. Which discounts apply together is decided by Shopify through the combination settings.

What can go wrong during the switch

• Hand-E Discounts does not replace payment and shipping scripts. Shopify has separate function types for those.
• Per store, at most 25 discount functions are active. If you split many scripts into many separate discounts, keep an eye on that number.
• Where several rules used to run one after another inside one script, the combination settings now decide what applies together. Recalculate carts in which two rules apply at the same time.
• The cart preview knows nothing about other discounts, schedules, customer groups, markets, taxes or shipping. A test purchase belongs before the launch.
• If you uninstall the app, Shopify removes its discounts. Plan the switch so that you do not change apps in the middle of a promotion.
