About Margin Proof
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.
