A silent auction is a fundraiser where guests bid on donated items by writing bids on a sheet or entering them online — instead of an auctioneer calling out bids. When bidding ends, the highest bid on each item wins. Online silent auctions let supporters bid from any device, all week long, and check out automatically.

A silent auction is a fundraising event where supporters bid on donated items and experiences over a set period of time. Instead of an auctioneer calling out bids, each item has its own bid sheet — on paper at an in-person event, or on a web page for an online auction. Bidders write or tap in an amount higher than the current bid, and when bidding closes, the highest bidder for each item wins and pays.
Silent auctions are one of the most popular ways to fundraise because they're flexible, low-pressure, and work for almost any cause — schools, nonprofits, churches, sports teams, and community groups all use them. They can stand alone as an online event or run alongside a gala, festival, or live auction.
Types of charity auctions
"Silent auction" is one of several formats, and many events combine them. Here's how the main types compare:
Online silent auction
Bidding happens entirely on the web over several days. Supporters bid from any device, get outbid alerts, and check out automatically. Reaches the widest audience and runs with the least staffing.
In-person silent auction
The classic table-and-bid-sheet format at an event. Great social energy, but limited to who's in the room and heavier on setup and manual checkout.
Live auction
An auctioneer sells a handful of high-value items one at a time to a gathered crowd. High drama and high price ceilings — best for a few headline lots, not volume.
Hybrid auction
Online bidding opens days before an event, then continues or closes live in the room. Combines the reach of online with the energy of a live event — increasingly the default.
Raffles, fund-a-need appeals, and "buy now" sales are often added on top to raise even more. New to the format? Start with what a silent auction is.
How an online silent auction works
Modern silent auctions are mostly run online, which removes nearly all the manual work. The flow is simple:
Set up
Create your auction page and add items with photos, descriptions, and starting bids.
Share
Send the link by email and social, or print QR-coded sheets for in-person bidding.
Bid
Supporters bid from any device. Outbid alerts pull them back to raise their bids.
Close & pay
Winners are identified automatically and pay by card — no checkout line.

Why run a silent auction?
- It raises real money. Competitive bidding often pushes winning bids to — or above — an item's retail value.
- Almost anyone can do it. No auctioneer, no venue, and no technical skill required when you run it online.
- It engages your whole community. Donors, local businesses, and bidders all take part, which deepens support beyond a single gift.
- It's low-cost to start. With free software and donated items, most of what you raise goes straight to your cause.
