Shipping, discounts, billing is a Shopify app that lets you define your own product, order, and shipping discount rules — then runs them as Shopify Functions directly inside the checkout pipeline.

How it works
From install to live checkout discounts in three steps.
Install the app
OAuth into your Shopify store with the scopes the app needs to read products and write discounts.
Configure rules
In the embedded admin, add product, order, and shipping discount rules with the criteria that matter to you.
Discounts fire at checkout
Each rule is published to a shop metafield; Shopify Functions read it and apply discounts on every cart.
