WinningBidder.com offers low cost online auction software tailored for fundraising purposes. Our user-friendly software ensures that event organizers can initiate an auction within minutes, while maintaining a rich array of features. Bidders can take advantage of features such as maximum bidding, outbid alerts, and dynamic "popcorn" bidding.
Rather than requiring bidders to download an app, our approach involves sharing a personalized auction URL with supporters. This enables them to explore listed items and place bids using any device. The system operates at remarkable speed, making it particularly suitable for events held in areas with unreliable connectivity, such as charity golf outings.
WinningBidder.com imposes no restrictions on the quantity of items, bidders, or events, making WinningBidder.com the ideal solution for all your online auction requirements throughout the year.

Auction event types include timed online auctions, simulcast auctions, blind timed auctions, catalog-only, fixed-price, and perpetual events. AuctionMethod includes a mobile app for iOS and Android, and reports a 94% renewal rate. For operations whose workflows fall outside the standard product, AuctionMethod also builds custom auction software development solutions at a fixed rate.
