Rate plan
A rate plan packages a price with its conditions. The same room might sell on a flexible plan, a cheaper non-refundable plan, and a breakfast-included plan, each with its own price and rules.
Rate plans let you reach different guests without changing the room itself. A traveller who wants certainty pays a little more for free cancellation; one chasing the lowest price commits up front. Managed well, they raise revenue across the same inventory.
