How do I stop a location selling below a margin floor?

Never under cost. The store won't take the price.

A floor on every line, enforced by the price list, not by a memo. A location that types a price under cost gets a warning, and a price under the floor doesn't save. When a supplier change runs through the network, the floor holds on every line while it runs. The one thing a franchisee can't accidentally break, and the one number HQ finance stops asking about. Promotions respect the floor too. A code that would take a line under cost stops at the floor instead.

The feature is called Margin warnings and floors. It runs on the same rails as everything else here: one catalog, one price list, one cockpit, your name on the front.
