Silent auction bidding — FAQ

What should the starting bid be at a silent auction?

A common rule of thumb is 30–40% of the item's fair-market (retail) value. Starting low invites more people to place a first bid and gets the competition going, which usually drives the final price higher than a high starting bid would.

How much should the bid increment be?

Around 10% of the item's value is typical. Big enough to move the price up meaningfully with each bid, small enough that bidders keep going. This calculator suggests one automatically, with a $5 minimum.

What is a 'buy-now' price?

An optional price — often about 150% of retail — that lets an eager bidder claim the item immediately and end the bidding. It's a great way to lock in a strong result for popular items.

Can VenueFuze run the whole silent auction?

Yes — item catalog, bid sheets, buy-now, runner-up offers, a settlement basket, and pickup tracking, with cash and card recorded together and paid to your own processor.
