Shopify Scripts and Functions for Custom Discounts

Shopify Scripts let Plus merchants run custom discount, shipping and payment logic — but Shopify is moving this power to Functions, a faster and more flexible system that is available more widely. If you rely on Scripts, it is time to plan the move.

What Functions can do

  • Custom discount logic, including stacking and complex conditions.
  • Custom shipping and delivery rules.
  • Payment method customisation and ordering.
  • Cart and checkout validation.

Why Functions, not Scripts

Functions run natively and safely inside Shopify, so they are fast and upgrade-safe, and they work beyond just Shopify Plus in many cases. Building on Functions future-proofs your store as Shopify retires the older Scripts approach.

Get the tricky stuff right

We have seen projects stall because an unusual rule — like applying two discounts to one product — was left until the end. With Functions, that kind of custom logic is entirely doable when it is scoped early. Experts Cabin builds custom discount and cart logic with Shopify Functions.
