Abstract: A system and method of managing purchasing contracts between supplier entities and customer entities for the purchase of products includes the step of generating at least one purchasing contract between at least one supplier entity (e.g., a product originator such as an airline company or a distributor such as travel agency) and at least one customer entity. The purchasing contract generated is one that is applicable to one or more contracted purchasing transactions effected, at least partially, through a computerized system. The generating step includes identifying one or more contract terms, wherein each contract term has one or more term attributes, and storing a term data set of the term attributes associated with each contract term in one or more computer databases. The method also involves collecting transaction data relating to one or more purchasing transactions and storing the transaction data in one or more computer databases.
