Abstract: Methods, systems, and computer program products for implementing purchase control services are provided. A method includes generating a record for a business agreement established between a customer and a supplier, and entering terms of the business agreement into corresponding data fields. The method also includes linking key data fields in the record to one or more information sources. In response to receiving an item from the supplier entity, the method includes creating a standardized record for the item, mapping the standardized record to at least one of the information sources and the record, reviewing the item for missing and incorrect data and supplying missing or correct data to the standardized record from at least one of the information sources. The method further includes comparing data in the standardized record with data provided in one of the pricing schedule and the record and resolving discrepancies, if discovered, in response to the comparing.
