Shopify Scripts → Shopify Functions
Shopify Scripts migration, done for you.
Shopify Scripts stopped executing on June 30, 2026. If your discounts, shipping rules or payment logic were built with the Script Editor, they are no longer running at checkout. We rebuild them as Shopify Functions — audited, tested against your real carts, and deployed fast, so you stop losing revenue.

Shopify Scripts could no longer be edited or published.
June 30, 2026
All Shopify Scripts stopped executing entirely — discounts, shipping and payment logic built as Scripts went silent at checkout.
Now
Every affected store is either migrated to Shopify Functions, or running checkout without the custom logic it depends on.
The most common symptoms right now: automatic discounts that no longer apply, shipping options appearing that should be hidden, VIP/tiered pricing gone, and payment methods showing for the wrong customers.
What each script becomes
Every Script Editor use case has a Shopify Functions equivalent:
| Your old script | What it did | Its replacement |
|---|---|---|
| Line-item scripts | Discounts you built in Ruby — tiered pricing, BOGO, VIP discounts, bundle pricing. | Discount Functions (product, order and shipping discounts — now combinable) |
| Shipping scripts | Hiding, renaming or reordering delivery options; conditional shipping rates. | Delivery Customization Functions |
| Payment scripts | Hiding, renaming or reordering payment methods at checkout. | Payment Customization Functions |
| Checkout logic & rules | Quantity limits, purchase validation, B2B rules. | Cart & Checkout Validation Functions + Checkout UI Extensions |
Functions are WebAssembly modules deployed through an app — faster and more reliable than Ruby scripts, configurable by your team in the admin, and (unlike Scripts) most work on standard Shopify plans, not just Plus.
How we migrate your scripts
1. Free script audit (same day)
Send us your store's Scripts customizations report (or admin access) — we catalogue every script, what it does, and its revenue impact. You get a fixed quote and timeline within one business day.
2. Classify & map
Each script is mapped to its Shopify Functions equivalent — discount, delivery or payment customization — and we flag anything that needs a Checkout UI Extension or a different approach.
3. Rebuild as Functions
We rebuild your logic as Shopify Functions (WebAssembly modules deployed through a custom app) with merchant-friendly settings in your admin — so your team can tweak values without touching code.
4. Test against real carts
Every function is tested against your actual cart scenarios and edge cases side-by-side with the old script logic before anything goes live.
5. Deploy & monitor
We deploy, verify discounts and shipping behave identically at checkout, and monitor the first days of orders. You own the app and the code — no lock-in.
Why PRP Webs for this migration
Shopify Functions live inside apps — and we are an agency that builds and publishes its own Shopify apps, alongside 12+ years of Shopify Plus development and checkout work (including checkout.liquid → Checkout Extensibility migrations). You get a fixed quote before work starts, you own 100% of the code, and every hour is visible to you in real time.
Frequently asked questions
What happened to Shopify Scripts?
Shopify deprecated Shopify Scripts: editing and publishing ended on April 15, 2026, and on June 30, 2026 all Scripts stopped executing entirely. Any discounts, shipping rules or payment logic built with the Script Editor no longer run — stores that have not migrated have lost those customizations at checkout.
What replaces Shopify Scripts?
Shopify Functions. They cover the same jobs — product/order/shipping discounts, delivery customization and payment customization — plus new ones like cart and checkout validation. Checkout UI Extensions handle the visual side of checkout customization.
My discounts stopped working after June 30. Can you fix them quickly?
Yes — that is exactly what this service is for. Simple discount or shipping scripts can usually be rebuilt as Functions and live within days. Send us your scripts (or their descriptions) and we will confirm a timeline the same day.
Do Shopify Functions require an app?
Yes. Functions are deployed inside an app built with Shopify CLI. We build it as a private custom app that you own, with an admin interface so your team can adjust discount values and rules without code.
Can I migrate Shopify Scripts myself for free?
If your scripts are simple, Shopify offers a "Replace your Shopify Scripts" flow in the Script Editor that recreates basic discounts natively. Complex logic — tiered pricing, combined conditions, custom shipping/payment rules — needs a developer to rebuild it as Functions.
Do I need Shopify Plus for Functions?
No — that is one of the upsides. Scripts were Plus-only, but most Shopify Functions work on standard plans too (some advanced checkout capabilities remain Plus-specific). Your discount logic becomes more portable than it was.
How much does a Scripts-to-Functions migration cost?
It depends on how many scripts you have and their complexity. After a free audit of your scripts we give you a fixed, itemised quote — most single-script migrations are small, fast projects. No open-ended billing.
