Scripts → Functions
Deadline: Jun 30, 2026
Shopify Scripts stop
working on June 30, 2026.
We help Plus brands
migrate safely.
If your store still uses legacy Shopify Scripts for discounts, shipping, payment logic, VIP pricing, wholesale rules, or campaign logic, it needs to be audited before the deadline.
Why now
Migration requires planning, testing, and replacement logic. Brands that wait until late Q2 2026 risk checkout regressions during the busiest selling period of the year.
Who this is for
Shopify Plus brands with active script-based logic affecting discounts, shipping, payment, customer groups, or campaign behavior.
Why This Matters
Checkout logic is at risk.
Shopify Scripts are being deprecated. After June 30, 2026, scripts no longer execute at checkout. Discount, shipping, and payment behavior that depended on script logic will silently stop applying.
Migration is not a like-for-like swap. Shopify Functions has a different execution model, different testing surface, and different edge-case behavior than the Scripts editor.
For Plus stores running active campaigns, VIP pricing, wholesale pricing, or bundle logic in scripts, the migration needs planning, testing, and rollout strategy. This is especially important for stores with checkout customizations layered on top.
What We Audit
Migration Options
Shopify Functions
The primary replacement path for most discount, shipping, payment, and cart logic. Native Shopify execution at the checkout layer.
Checkout UI Extensions
Where script logic was driving checkout UI behavior or content, UI Extensions handle the presentation layer alongside Functions logic.
Shopify Flow
For workflow logic that does not need to run inside checkout itself. Useful for downstream operations and conditional automations.
App-based replacement
Where Functions and Flow do not cover the use case, focused Shopify apps or custom logic can replace specific script behaviors.
Custom Shopify app logic
For complex or proprietary logic, a custom app gives you control over execution, testing, and ongoing maintenance.
Simplifying legacy logic
Some scripts can be retired. Others should be simplified before migration. The audit identifies which logic is still earning its place.
