The invention provides a computerized electronic auction payment system and method for effecting a real-time payment for an item won in an electronic auction by setting up and maintaining electronic auction payment accounts for prospective bidders and sellers. The prospective bidders provide funds to their electronic auction payment accounts maintained by the computerized electronic auction payment system, prior to being deemed as winning bidders, via direct deposit, using a credit card, or sending a check, money order, or other financial document to an operator of the computerized electronic auction payment system. In one embodiment, a prospective bidder authorizes the computerized electronic auction payment system to effect a real-time payment to the seller upon the prospective bidder being deemed the winning bidder (i.e., immediately following the conclusion of the auction). That is, without the winning bidder having to access a payment page via an Internet connection to a particular web site.
