Definition
An auction platform is online software used to host, manage, and conduct auctions. Major platforms for estate and consignment auctioneers include HiBid, AuctionFlex, LiveAuctioneers, Proxibid, BidWrangler, and Wavebid. These systems handle lot listing, bidding, payment processing, and post-sale reporting — serving as the operational backbone for modern auction businesses.
How It Works
Auctioneers upload lot data — descriptions, photos, and starting bids — to their chosen platform, which presents items to bidders online. Most platforms support timed online bidding, live simulcast (combining in-person and online bidders), or both. According to AuctionWriter's 2025 estate auction fee analysis, platform fees typically range from 3–5% of hammer price, baked into the buyer's premium or deducted from seller proceeds. Each platform has its own CSV or import format for catalog data, making standardized exports from independent cataloging tools a critical workflow step for auctioneers who sell on multiple platforms.

According to AuctionWriter's 2025 estate auction fee analysis, platform fees are typically baked into the buyer's premium or deducted from seller proceeds. Some platforms like HiBid offer tiered monthly plans. Always factor platform fees into your commission structure when setting seller terms.
