What is a reverse auction ?
A reverse auction is an auction where the buyer and seller roles are reversed. The buyer is the auction organizer, he invites several sellers (suppliers) to compete for the best purchasing conditions.
Reverse auctions are an important negotiation tool often used in b2b negotiations for the final contract conditions for a specific delivery.
Electronic Reverse Auctions are the most often used type for these purposes, because these have the advantage of rule automation and transparency for the participants.

» all bidders are considered in the auction with a continuously dropping price. The only action that a bidder may take is to drop out of the auction. Once the bidder drops out of the auction, he cannot not re-enter the auction.
