About the Arcanum Margin Keep
Margin Keep protects your profit margins during promotions by scanning discount codes and sale prices against your actual costs and fees. The app shows which costs are known, estimated, or missing for every margin check, so you always understand your profit floor.
Safety Studio lets you test promotions before launch and suggests safer discount options. The decision ledger tracks orders that need attention. Protect tier adds peak-sale profit floors, loss budgets, and real-time Slack or Teams alerts. Optional checkout Block stops unprofitable sales only when cost data is complete—incomplete costs never block a customer's purchase, ensuring you don't lose legitimate orders.
Launched: September 14, 2026
