Shopify Scripts Stopped on 30 June. Is Your Checkout Still Doing What You Think?

Shopify Scripts stopped running on 30 June 2026. Editing had already been switched off on 15 April. The deadline had moved before, most recently from August 2025, which is part of why some stores assumed it would move again. It did not.

If your store migrated its Scripts to Shopify Functions, none of this matters. If it did not, or you are not sure, the important thing to understand is how the failure looks: it does not look like anything. No error, no outage, no alert. The checkout works. It just stopped doing the things the Scripts told it to do.

Three months on, that is worth a ten-minute check.

What quietly changed on 1 July

Scripts were a Shopify Plus feature, written in Ruby in the Script Editor, and they came in three kinds. Each one fails in its own quiet way.

Line item scripts changed prices and discounts in the cart: tiered pricing, buy-X-get-Y, bundle discounts, wholesale pricing for tagged customers, free gifts over a threshold. When they stopped, the cart went back to full price, or to whatever ordinary discount codes still applied. Customers who expected a promotion saw a higher total. Some abandoned; some complained; some paid more than your marketing said they would.

Shipping scripts hid, renamed or reordered shipping rates: hiding express delivery for oversized items, removing a rate for PO boxes, renaming a carrier’s rate to something customers understand, offering free shipping to a customer segment. When they stopped, every rate the carrier returns came back, including the ones you had deliberately hidden because you cannot actually fulfil them.

Payment scripts hid or reordered payment methods: removing buy-now-pay-later on certain products, restricting payment options for wholesale accounts, putting a preferred gateway first. When they stopped, every enabled payment method became available on every order.

None of that throws an error. It shows up later, as a margin that looks wrong, a customer service thread about a missing discount, or an order you cannot ship the way the customer paid for.

How to check in ten minutes

1. Open the Scripts customisations report. Shopify provides it in the admin, under the checkout settings. It lists the Scripts your store had and suggests which Functions or apps can replace them. If it lists nothing, there is nothing to migrate and you can stop here.
2. Write down what each one was for. In business terms, not code: “10% off for trade customers”, “no express shipping on furniture”. Ask whoever runs promotions; they will know what they expected to happen even if nobody remembers the Script.
3. Place test orders against those rules. A cart that should get the tiered discount. A furniture item with an express address. A wholesale login at the payment step. Compare what happens with what the list says should happen.
4. Check what replaced them, if anything. An agency or developer may have migrated some rules to Functions or to an app before June. Make sure the replacement matches the original behaviour, not an approximation of it.

If everything you listed still behaves correctly, you are done. If not, you have the list of what to rebuild.

Moving to Shopify Functions

Shopify Functions are the replacement, and in most ways they are better: they run inside Shopify’s own infrastructure, they are faster, and they are not limited to the checkout moments Scripts could reach. The mapping is broadly:

Scripts did	Functions replacement
Line item discounts, tiers, bundles	Discount functions, and cart transforms for bundles
Hiding, renaming or reordering shipping rates	Delivery customisations
Hiding or reordering payment methods	Payment customisations

The practical decision for each rule is app or custom:

• An existing public app already uses Functions for common patterns like tiered discounts and payment method rules. If one covers your rule exactly, it is usually the quickest fix.
• A custom app is right when the rule is specific to your business, or when stacking three apps to approximate one rule would be more fragile than writing it once. Custom apps containing Functions are only available on Shopify Plus, which is where Scripts ran in the first place, so any store that had Scripts can use them.

A common trap: rebuilding every old Script exactly as it was. Some of those rules existed to work around limits Shopify has since removed, and some promotions they supported ended years ago. The migration is a good moment to delete what nobody needs.

Where this fits

Scripts are the latest part of Shopify’s checkout to be replaced, after the move from checkout.liquid to Checkout Extensibility. Both changes point the same way: customisation now runs through Functions and extensions rather than code injected into the checkout. That is better for stability, and it means checkout work now needs people who know the current platform rather than the one they learned on.

That is the reason three of our developers hold Shopify certifications. If your store is on Shopify Plus, or considering it, the checkout is where the difference shows. More on our Shopify development work, and on what a Shopify Plus build costs in Australia.
