Shopify has officially announced the deprecation of Shopify Scripts, meaning all existing scripts will stop working after June 30, 2026. Merchants using Scripts for discounts, shipping rules, or payment customizations must migrate to Shopify Functions and Checkout Extensions to keep their checkout working properly. Need help?
Checkout Boost helps Shopify Plus brands replace legacy Scripts with powerful, scalable checkout customizations using Shopify’s new architecture.
At Checkout Boost, we understand how important it is for Shopify Plus brands to stay ahead of platform changes. That’s why we help merchants transition from legacy scripts to modern checkout extensibility — bringing smarter logic, better performance, and future-ready checkout experiences.
Our team analyzes all active scripts, including discount logic, shipping rules, and payment customizations, to understand how your checkout currently behaves.
Each script is mapped to the appropriate Shopify Functions or Checkout Extensions to ensure the same logic continues to work in the new system using Checkout Boost.
We rebuild your scripts using Shopify’s modern framework and thoroughly test them to ensure everything works as expected.
We run final checks to confirm discounts, shipping rules, and payment conditions behave exactly as intended.
