FAQ
What exactly is Shopify Scripts migration?
Shopify Scripts are Ruby-based customizations used by Shopify Plus stores for checkout logic like discounts, shipping rules, and payment methods. Shopify is deprecating them on June 30, 2026. Migration means rebuilding that same logic using the new Shopify Functions system before the deadline.
Will my store break if I don't migrate before June 30, 2026?
Yes. After June 30, 2026, all existing Shopify Scripts will stop executing completely. Any custom checkout logic built on Scripts — discounts, payment rules, shipping customizations — will stop working, which can severely impact your checkout and revenue.
What's the difference between Shopify Scripts and Shopify Functions?
Scripts were Ruby-based code running in a sandboxed environment, limited to Shopify Plus. Functions are small programs written in JavaScript or Rust (compiled to WebAssembly) that run directly inside Shopify's infrastructure. Functions are faster, more secure, and support more use cases.
Do I need to be on Shopify Plus to use Shopify Functions?
For custom checkout logic (discounts, payment rules, shipping customization, and Cart Transform), yes — Shopify Plus is required. However, some basic Functions APIs are available to all Shopify plans via public apps.
How long does a typical Scripts migration take?
A single simple function (e.g., one discount rule) can be done in 2–3 days. A full migration covering multiple functions (discounts, shipping, payment, cart transform) typically takes 7–14 days depending on complexity.
Can you build new Shopify Functions from scratch, not just migrate existing Scripts?
Absolutely. Beyond migration, I can build brand new Shopify Functions including tiered discounts, bundle pricing logic, cart transform rules, checkout validation, and custom payment or shipping logic — all tailored to your specific business rules.
What is the Cart Transform API and do I need it?
The Cart Transform API is a Shopify Functions API that lets you modify how items appear and are priced in the cart — for example, merging products into bundles, applying bundle discounts, or overriding prices and product titles. If your store uses bundles or complex pricing, you likely need it.
Will my checkout be down during the migration process?
No. All development is done on a development store or staging environment first. The new Functions are fully tested before being deployed to your live store, ensuring zero downtime to your active checkout.
