[Glossary](https://blnkfinance.com/glossary) Yield management # What is yield management? Yield management Yield management is a pricing method that changes the price of a fixed, perishable inventory so the seller takes more revenue from the same stock. Airline seats, hotel rooms, and ad slots are the usual cases. It is not investment yield. The shared word is an accident of English. ## How does yield management work? The stock expires. An empty seat on tonight’s flight cannot be sold tomorrow. The seller watches demand and remaining supply, then raises or lowers the price so the last units still sell, but not so cheap that early buyers leave money behind. The method needs a forecast, a remaining-inventory count, and rules for who can buy at which price. Those rules live in the booking system. The ledger sees the sale after the price is set. ## Yield management vs investment yield Investment yield is a return on a bond or a deposit. Yield management is a revenue tactic. If you are looking for coupons, maturity, or a curve, you want the other pages. This one is about price and leftover stock. ## What the ledger should record The sale, the refund, and any fee. Not the forecast. If two customers paid different prices for the same room night, those are two transactions with two amounts. The pricing engine’s reason can sit in metadata. It should not invent a third kind of money. ## How it works with Blnk Blnk does not pick the price. Your booking or billing system does. When the sale happens, post the amount you actually charged. The source is the customer wallet or a clearing balance. The destination is `@Revenue`. A refund is a new transaction back along that path, not an edit of the sale.
