Disclosed embodiments provide an electronic procurement system and process that enables a buyer or purchasing organization to maintain explicitly or implicitly, a contract price between the buyer/purchasing organization and the supplier whose catalog is integrated with an electronic marketplace. In one embodiment, a process is executed that compares the listed/purchase price of catalog items against the contract price or against a ‘normal’ purchase price. A user (e.g. the buyer) may configure and receive specific alerts regarding items that are purchased in deviation of contracted price and items that have been added to the catalog since the last contract. Disclosed embodiments may also maintain, automatically, the historical price and purchase information of supplier catalog items that are enabled through the electronic marketplace.
