A timed online auction is a sale conducted entirely on a digital platform, where each lot opens at a set time, accepts bids over a defined window (often 3–10 days), and closes at a scheduled close time. There is no live auctioneer calling bids.
Timed auctions favor convenience — bidders can participate from anywhere on their own schedule, lots close in waves rather than all at once, and the platform handles all bid increments and proxy logic automatically. Most modern auction software supports timed auctions as the default mode, with live and hybrid as upgrades. Lower operational overhead means more auctioneers can run more frequent sales.
Timed auctions now account for the majority of total auction volume by lot count, even though live auctions still dominate by dollar value. The difference: timed auctions excel at moving high-volume, lower-value inventory (consignment store stock, estate household goods, vehicle wholesale) where the operational simplicity matters more than maximizing per-lot price. High-value collectibles, fine art, and specialty categories still tend to run live or hybrid because the price-discovery power of a live ring is worth the operational cost.
