A method is provided for inventory management which includes an initial step of receiving a customer request for an inventory item and then generating a table or menu of one or more inventory items that most closely correspond to the customer request using a price forecasting system. Based on negotiations concerning price, timing and other typical concerns, an item is selected from the table and a price quotation associated with the selected inventory item is generated using the price forecasting system, which price quotation has been predetermined by a yield management system using a pricing strategy. The customer information associated with the customer request is input into a traffic billing system. Information needed for price recalculation associated with the customer request is input into the yield management system. The yield management system recalculates pricing data with in a manner consistent with a pricing strategy implemented by the yield management system, so that price changes caused by a reduction in available inventory due to the customer request are taken into account, and the pricing data accessed by the price forecasting system when a price quotation is generated is updated prior to repeating the process for a subsequent customer request. This method provides more accurate pricing than known systems where order information must be entered manually before a price recalculation can take place, and the yield management system overestimates the amount of available inventory. If the customer request comprises a reservation having an associated probability of later becoming an order, the reservation is taken into account when recalculating prices based on available inventory. Such a process may be integrated for an enterprise made up of a number of member stations each having associated inventory for sale.
