Known as The Gindlesperger Method, the patent covers any electronic system for procuring customized goods or services that automatically matches supplier attributes with contract specifications to identify qualified suppliers, disseminates a bid solicitation to at least two identified suppliers and receives and forwards a bid response to the buyer. The simple methodology of this patent allows for a buyer to maintain its own qualified supplier base, obtain optimal cost reductions by establishing an environment in which the supplier is permitted to sell its excess capacity by bidding high, low or not at all without regard to buyer pricing expectations, without setting a precedent for its next bid price and while ensuring inclusion in the next bid opportunity on which the supplier is qualified.
