Types of auctions explained

"Auction" isn't one thing. English, Dutch, sealed-bid and live auctions each move price in a different direction and reward different behaviour. Choosing the right one is the single biggest lever on how a sale performs. Here's each in plain English, and when to use it.

By the BidWright team · Auction software studio

English (timed / ascending)

The one most people picture: the price goes up. Bidders compete, each topping the last, and the highest bid when the clock runs out wins — as long as it clears the reserve. Online, it's powered by proxy bidding and soft close so the genuine top bidder wins, not the fastest. It's the default for vehicles, property and estate sales because it maximises competitive tension.

Dutch (reverse / descending)

The mirror image: the price starts high and falls until the first buyer accepts. There's no bidding war — waiting gets you a lower price, but someone else might grab it first. That tension makes Dutch auctions fast, which is why they suit clearance, perishable goods and high volume. With multi-quantity lots, many buyers can take units at the live price until stock runs out.

Sealed bid (highest or lowest wins)

Everyone submits a confidential bid; nobody sees the others until close. Two variants matter:

Highest wins

The best secret offer takes the lot, with the reserve acting as a minimum. Ideal for premium, sensitive or discreet sales where you don't want an open bidding war.

Lowest wins

The cheapest secret offer wins, with the reserve acting as a maximum. This is how tenders and procurement work — suppliers compete on price without seeing each other.

Live (automated)

A live auction recreates the saleroom: lots are presented and called in real time — "who'll open?", active bidding, going once, going twice, sold. BidWright runs that cadence automatically, with an 8-second silence timer that resets on every bid and a dynamic bid ladder, so online and in-room buyers compete together without a human caller. It's the natural fit for livestock and marquee sales.

Frequently asked

What is the difference between an English and a Dutch auction?
An English auction ascends — bidders compete upward and the highest bid at close wins. A Dutch auction descends — the price starts high and falls until the first buyer accepts. English maximises competitive tension; Dutch maximises speed.
When should I use a sealed-bid auction?
Use sealed bids when you want confidential offers — tenders and procurement (lowest wins) or discreet, premium sales (highest wins). Nobody sees competing bids until close.
What is a live online auction?
It recreates the saleroom rhythm in software: lots are presented and called — going once, going twice, sold — with online and in-room buyers bidding together in real time. BidWright's runs that cadence automatically, with no human caller required.
