Keep promotions profitable after costs. Spot bad sale prices and codes before they wipe your margin.
Margin Keep is campaign insurance for promotions. Scan discount codes and sale prices against your profit floor after costs and fees—with known, estimated, or missing cost labels. Safety Studio lets you try a discount or sale price before go-live and see safer options. The decision ledger shows which orders to watch. Protect adds peak-sale floors, Slack/Teams alerts, and Admin pause. Optional Block stops checkout only when costs are trustworthy; incomplete costs never block a sale.
