As Shopify continues to evolve its platform to support greater scalability and flexibility, it’s phasing out Shopify Scripts in favor of the newer, more powerful Shopify Functions. For merchants who rely on Scripts for custom discount logic and cart level promotions, now is the time to understand what this change means and how to prepare.
At Ecommerce Partners, we’ve already helped clients successfully transition their logic from Scripts to Functions. Whether you have a single Script or dozens, we can help ensure a smooth and reliable migration.
What’s Happening?
Shopify has officially announced that Shopify Scripts will be deprecated by **June 30, 2026**. After this date:
- New
checkout.liquidor Script Editor based customizations will no longer be supported. - Existing Scripts will stop working entirely.
- All checkout customizations must be built using Shopify Functions.
This change is tied to Shopify’s broader shift toward Checkout Extensibility, which allows merchants to customize checkout in a more secure and performant way while keeping their stores eligible for Shopify’s fastest checkout upgrades.
✔ If you’re still using checkout.liquid and Scripts, you’ll need to migrate before the **June 2026** cutoff to avoid disruptions.
Shopify Scripts vs Shopify Functions
| Feature | Shopify Scripts | Shopify Functions |
|---|---|---|
| Language | Ruby (via Script Editor) | Native Rust, configurable via Admin UI |
| Where it runs | Script Editor, applies in checkout only | Runs deep inside Shopify infrastructure |
| Performance | Can slow checkout if misused | Highly optimized, runs instantly |
| Upgradeability | Deprecated | Built for long term flexibility |
| Compatibility | Not supported in one page checkout | Fully compatible with all checkout upgrades |
What Can You Do With Shopify Functions?
Functions allow you to create customized checkout logic with far more power and stability than Scripts. Use cases include:
- Tiered discounts and volume based pricing
- BOGO logic and combo deals
- Custom payment method conditions
- Advanced shipping rate logic
- Wholesale or B2B pricing rules
- Loyalty based discounts
The best part? These customizations run natively within Shopify’s infrastructure, meaning they are faster, more secure, and easier to manage via the Admin UI or an app.
Why You Should Migrate Now
Waiting until the last minute could mean rushed implementations, missed promotions, or a broken checkout. Migrating early ensures:
- Zero downtime when Scripts are turned off
- Time to test and refine your new logic
- A chance to optimize (not just replicate) your old discount structure
- Full compatibility with Shopify’s upcoming checkout updates
