An Electronic Reverse Auction is a type of online auction in which the traditional roles of buyer and seller in an auction are reversed. In an ordinary auction, buyers compete to obtain goods or services by offering increasingly higher prices. Conversely, in an electronic reverse auction, there is one buyer and many potential sellers. The sellers compete to obtain business from the buyer, and prices will typically decrease as the sellers underbid each other.
