Auction Platform

An auction platform is online software used to host, manage, and conduct auctions. Major platforms for estate and consignment auctioneers include HiBid, LiveAuctioneers, Proxibid, AuctionFlex, AuctionZip, and Wavebid. Each platform provides bidder registration, lot display, bidding infrastructure, and payment processing — the auctioneer's job is to upload their catalog (lot data, descriptions, and photos) in the platform's required format.

How It Works in Practice

Auctioneers upload lot data — descriptions, photos, and starting bids — to their chosen platform, which presents items to bidders online. Most platforms use CSV or spreadsheet imports for bulk catalog uploads, each with different column requirements and photo naming conventions. HiBid dominates the estate auction space with the largest buyer pool in the United States. LiveAuctioneers focuses on fine art and high-end antiques. Proxibid serves industrial, commercial, and government surplus auctions. Many auctioneers list on multiple platforms simultaneously to maximize buyer reach. Platform-independent cataloging tools like Gavelist generate descriptions once and export to any platform's format.

Frequently Asked Questions

What auction platform is best for estate sales?
HiBid has the largest buyer pool for estate auctions in the United States. However, many auctioneers list on multiple platforms simultaneously — HiBid for reach, LiveAuctioneers for fine art buyers, and their own website for local bidders. The best platform depends on your buyer demographics, lot categories, and whether you run live, timed, or simulcast auctions.
How much do auction platforms charge?
Pricing varies by platform and model. HiBid charges a buyer's premium (typically 10–18%, passed to the buyer) plus optional subscription fees. LiveAuctioneers charges per-lot listing fees plus a percentage of hammer price. Proxibid uses subscription-based pricing with tiered lot allowances. Compare total cost per lot across platforms and factor in buyer pool size — a higher-fee platform with more bidders often nets better results than a cheaper platform with less traffic.
