How to Run an Online Charity or Silent Auction
An online auction lets supporters who cannot come to your gala, school fair or appeal still bid — and lets the ones in the room keep bidding on their phones. This guide covers the whole job, from asking for donated items to thanking the winners.

Set a goal and a date
Decide what you are raising money for and roughly how much, then pick the dates. Most charity auctions either stand alone for a week or so, or run alongside an event: bidding opens a week before and the lots close during the evening itself. A clear cause and a deadline are what make people bid.
Collect donated items
- Ask widely and early. Local businesses, parents, members and supporters donate goods, services and experiences: a meal, a weekend away, a signed shirt, a day with a professional.
- Use a simple donation form. Record the donor, a description, any restrictions (dates, expiry) and how the item or voucher will be delivered.
- Favour things people want. Experiences and bundles often raise more than single objects. Group small items into themed packages.
Write lots that sell
Give every lot a clear title, a good photo, what exactly the winner receives, any conditions and the donor’s name — donors like to be credited. Where you know it, state the item’s value. In some countries, including the US, a winning bidder can only treat as a donation the amount paid above the fair market value of what they receive, so charities often publish a value for each item. Check the rules where you are.
Set starting bids and increments
Start bids low enough to get the first bid quickly — around a third to a half of the item’s value is a common starting point — and use increments that feel natural for the price. A lot with no bids looks unloved; a lot with a few early bids attracts more.
Promote it to your supporters
Send the link to your mailing list, share it on social media and ask donors to share their own lot. Send reminders when bidding opens, a day before the close and in the last hour. On the night of an event, show the link and a QR code on the tables and the screen.
Close the bidding fairly
Close lots in small batches rather than all at once, so bidders who lose one lot can move to the next. Use soft close: a bid in the final minutes extends that lot’s clock, which stops last-second sniping and keeps the atmosphere good in the room.
Collect payment, deliver and say thank you
Ask winners to pay online straight after the close, before volunteers go home; chasing payments for weeks is the most common headache. Then arrange delivery or collection, send receipts in the form your country requires, and thank both winners and donors — publishing the total raised is the best thank-you of all, and it brings people back next year.
Frequently asked questions
What is the difference between a silent auction and a live auction?
In a silent auction people place bids without an auctioneer, traditionally on paper bid sheets and now usually on their phones, and the highest bid when the lot closes wins. A live auction is called by an auctioneer in the room. Many events run both: a silent auction for most lots and a short live auction for a few headline items.
How long should an online charity auction run?
About a week works well for a stand-alone appeal. When it goes with an event, open bidding a few days to a week before and close the lots during the evening.
What items raise the most at a charity auction?
Experiences and things money cannot easily buy — a behind-the-scenes visit, a holiday home for a week, a signed item — and well-put-together packages usually raise more than single everyday objects.
Can winning bidders claim their bid as a donation?
It depends on the country. In some, including the US, only the amount paid above the fair market value of the item counts as a donation. Check the rules where you are before promising anything to bidders.
