Abstract: A system and method providing comprehensive, end-to-end collaboration and transaction functionality for a world-wide market for products and services. Buyers suppliers and distributors are electronically connected, via a communications network for the procurement and delivery of both standard and custom products or services. Purchase orders are received at an electronic repository connected with the network, such as a website and associated memory. In response to the received purchase orders, one or more quotes are received at the repository. One method includes aggregating buyers based on a purchase order commonality, while another method includes aggregating suppliers based on capacity similarities. After a match is made and processed, a procurement transaction is executed between a buyer and one or more suppliers via electronic communication over the communications network.
