Best Nonprofit Software for Fiserv

AuctionMethod is a customizable auction platform designed specifically for auction businesses since its inception in 2012. It features a flat-rate pricing structure that is ideal for nonprofits conducting fundraising auctions. You can host various types of events—including timed online, live simulcast, silent, and hybrid auctions—on a fully branded website under your own domain, ensuring that donor focus remains on your organization instead of a third-party marketplace. Use the Auctioneer Toolbox mobile app, available for both iOS and Android, to catalog donations, oversee bidder registration and qualifications, and streamline post-event invoicing and receipt processes. With integrated payment options through Fiserv, Stripe, Authorize.net, and others, funds flow directly into your merchant account without any commissions or percentage deductions, allowing nonprofits to retain more of their fundraising efforts. Enjoy unlimited access to auctions, lots, images, and bidders as part of the standard offering. Mailing list integrations with Mailchimp and Constant Contact facilitate effective promotion of your events. The platform boasts a remarkable 100% uptime, a 94% renewal rate, and has earned the 2026 Top Performer Award in Auction Software from SourceForge.
