What is a fast block auction?
A fast block auction is a timed online format that recreates the rapid-fire pace of a live auction ring — lots cross the block one after another on short, resetting clocks, so a big catalog clears in one fast session.
A fast block auction takes the rhythm of a live ring — where the auctioneer moves briskly from lot to lot — and reproduces it online. Each lot opens, accepts bids against a short countdown, and hammers in seconds. As soon as one lot closes, the next is "on the block," keeping the whole sale in constant motion.
The mechanic is simple: a brief timer runs on the active lot, and every new bid resets the clock by a few seconds. Bidding stays decisive because no one has days to deliberate — the lot in front of you is selling now. This makes the format well suited to high-volume catalogs like vehicle fleets, repossessions, equipment surplus, and routine consignment runs.
Example: a dealer needs to liquidate 400 trade-in vehicles. Rather than scheduling a multi-day timed sale or staffing a full webcast crew, they run a fast block auction. Lots open in sequence on a ten-second clock, bidders watch the block advance in real time, and the entire fleet sells in a single evening. Unovance supports fast block as one of 22 formats — you set the block order, increments, and timing, and run it on a branded platform you own.
What defines a fast block auction.
One lot, one block, seconds to sell
A fast block auction compresses the live ring rhythm into a tight, automated cadence — each lot opens, takes bids, and hammers in seconds rather than minutes.
Short, resetting bid clock
A brief countdown runs on every lot. Each new bid resets the clock by a few seconds, so action stays continuous and the sale keeps moving down the catalog.
Built for high lot counts
It shines when you have hundreds or thousands of lots to clear in a single session — surplus, repossessions, or routine consignment runs that would stall a slower format.
Live-feel without an auctioneer chant
Buyers get the urgency of a live ring online, while clerking, increments, and the block order run automatically behind the scenes.
Frequently asked questions
What is a fast block auction?+
A fast block auction is a timed online format that mimics the rapid pace of a live auction ring. Lots cross the “block” one after another on a short, resetting countdown — typically a few seconds each — so a large catalog can be sold in a single fast-moving session instead of over days.
How is it different from a standard timed auction?+
A standard timed auction gives each lot a fixed end time, often days out, with anti-snipe extensions. A fast block auction is sequential and live-paced: lots sell one at a time in block order on very short clocks, recreating the cadence of an auctioneer working the ring rather than a long, parallel countdown.
When should I use a fast block auction?+
Use it when you have a high lot count to clear quickly and want live energy without staffing a full webcast crew — for example a fleet of repossessed vehicles, dealer surplus, or a routine weekly consignment run. The format keeps buyers engaged and turns inventory fast.
