The present invention provides a system and method for optimizing a purchase order. While generating a purchase order, a purchasing agent may aggregate a company's purchasing requirements into a single purchase order, receive notification of a supplier's offers for discounts to determine whether it would be advantageous to modify a purchase request, or view evaluations of a supplier's past performance. Upon receipt of a purchase request, potential suppliers are identified to fulfill the request. A purchasing agent may then see whether a purchase request may be aggregated with other purchase requests or whether conditions are present that may trigger other opportunities to optimize the purchase order. As a result, a purchase order is generated that has been optimized to reduce costs as well as take advantage of other benefits that the purchaser may be interested in.
