Abstract: Disclosed are methods, systems, and program code that enable a nonprofit organization to manage its fundraising activities online, including online hosting of auctions, and auction services such as maintaining donor/bidder registries, bid tracking, processing credit cards, and auction closeout activities. A consignment database enables organizations to build catalogs using items made available from a consignment catalog for inclusion in an auction or raffle. Also disclosed is a sponsor engine that enables registered donors to contribute all or a portion of the cost of a consignment item. The sponsor engine uses the cost of the item and the number of desirable donors to suggest a plurality of sponsorship levels, for example $50, $100, $150. The sponsor engine computes and compares the total of received sponsorship dollars with the cost of the consignment item, and either closes sponsorships once the price has been reached or instantiate a new similar consignment item.
