AuctionMethod is white-label auction software built on a flat-fee model: no commissions, no per-lot fees, no platform skim, and no contract, so clients keep the revenue from every sale instead of splitting it with the platform. Since 2012, AuctionMethod has also offered custom auction software development for auction businesses whose workflows do not fit an off-the-shelf platform. Based in Massachusetts, serving the U.S., Canada, Australia, and New Zealand, AuctionMethod works with auctioneers, estate liquidators, farm and heavy equipment, industrial, salvage and recycling, non-profit, corporations, retail liquidators, auto/car dealers, real estate, arts and collectibles, and single-use auction businesses. Clients keep 100% ownership of their bidder lists, seller lists, item data, images, and transaction history on a fully white-label auction website rather than a shared marketplace listing. AuctionMethod has earned the SourceForge Spring 2026 Top Performer Award in Auction Software and is rated 4.9/5 on Capterra and SourceForge, with a 94% renewal rate. The platform handles catalog and lot management, consignor setup, bidder registration, invoicing, payment processing, tax handling, and reporting, and supports auction event types including timed online auctions, simulcast auctions, blind timed auctions, catalog-only, fixed-price, and perpetual events. For live, rapid-fire simulcast auctions, latency is critical: AuctionMethod specializes in real-time speed under one second so online bidders do not miss the auctioneer's hammer, running on infrastructure that is fully hosted with daily backups, auto-scaling for high traffic, and security updates included, with 100% uptime tracked on a public status page.
