If you’re running a Shopify Plus store, this is an important update you can’t ignore.

Starting June 30, 2026, Shopify Scripts used for checkout customisation will stop working. Any logic built for discounts, shipping rules, payment conditions, or line-item modifications will break unless migrated in time.

This change affects all Shopify Plus merchants currently relying on Scripts.

What’s Changing?

Shopify Scripts → Deprecated
Shopify Functions → New Standard

Shopify is moving checkout customisation to Shopify Functions, which are faster, more secure, and future-ready.

If your checkout depends on Scripts, migration is mandatory, not optional.

What You Should Do Now (Clear Action Plan)

1️⃣ Review Your Existing Scripts

Audit all Scripts currently running on your store:

  • Payment customisations
  • Shipping logic
  • Discounts & promotions
  • Line-item rules

2️⃣ Plan the Migration

Map each Script to its equivalent Shopify Function.
Most use cases are fully supported, but structure and logic will change.

3️⃣ Test in a Safe Environment

Implement and test Functions on a development store to avoid checkout issues.

4️⃣ Deploy Before the Deadline

Go live well before June 30, 2026 to ensure uninterrupted checkout performance.

Why This Matters for Revenue

Checkout issues = lost conversions.

Waiting until the last moment can cause:

  • Broken discounts
  • Payment failures
  • Customer drop-offs
  • Revenue loss during peak sales

Early migration keeps your store stable, fast, and scalable.
