Blocks checkout when a discount would sell below your minimum margin. Automatic profit protection.
Stacked promos and generous discount codes can quietly sell orders at a loss. Margin Proof stops that at the last step: a Shopify checkout validation reads your COGS data and the discounted order total, and blocks checkout when an order would drop below the minimum net margin you set. Customers just remove the code to continue. Set one rule, import COGS from Shopify, CSV or manually, and see how much discount each product can safely take. In English and Portuguese.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows Margin Proof on a store, it is there.
