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.
Pricing starts at $100/mo with a $250 one-time setup charge and is published publicly, with a 30-day free trial and no credit card required.

AuctionWorx Enterprise
RainWorx Software presents AuctionWorx, a cloud-based platform for online auctions that is tailored for both desktop and mobile users.
The software comes in two distinct editions tailored to different auction needs:
AuctionWorx Enterprise is designed primarily for managing individual listings rather than traditional auction events, making it ideal for marketplaces where items close at varied times; additionally, it can be set up for a sole seller without the complexity of auction event management.
On the other hand, AuctionWorx: Events Edition is specifically crafted for conducting scheduled timed auctions, allowing each auction to feature a collection of lots that share key information, including start dates and organized closing times, with an easy-to-navigate homepage showcasing upcoming events that can be explored individually.
This flexibility in options ensures that users can select the edition that best meets their auctioning requirements.
