Silent Auction

How a silent auction works

The mechanics are simple, and it helps to have them clear before you plan anything. Each item has a description, a value, a starting bid and a minimum raise. Guests write or enter a bid higher than the last one. At the closing time, bidding stops and the highest bidder wins.

Most silent auctions run alongside another part of the event, such as a dinner, a reception or a program. Bidding opens when guests arrive and closes before or just after the main program, so the auction fills the time that would otherwise be idle and gives guests a reason to circulate. Some organizers close items in waves, so the room does not empty at once.

Decide one thing first: whether the auction is paper, mobile or both. Paper bid sheets need no devices and suit smaller rooms and older audiences. Mobile bidding lets guests bid from their seats and receive an alert when they are outbid, and it also lets people who cannot attend take part. The rest of the plan follows from that choice.

Sourcing items that sell

Items decide the result. A table of ten good items will outraise a table of forty forgettable ones. Start asking about three months out, and ask for specific things instead of general donations.

• Experiences

  A private dinner, a behind-the-scenes tour, a weekend stay or a lesson with an expert. Experiences cost the donor little and feel exclusive to the winner.

• Local business gift certificates

  Restaurants, salons, studios and shops. Bundle several small certificates into one themed basket so the item has presence on the table.

• Items tied to your mission

  Something only your organization can offer, such as naming a program, meeting a beneficiary or a signed piece from your community. These often outsell generic goods.

• Board and sponsor donations

  Ask each board member and sponsor to bring one item or one introduction. A personal ask from a known name works better than a mailed form.

• Packages

  Combine a certificate, a bottle and a card into a theme such as a date night or a game day. A package lets you set a higher value and a higher starting bid.

Setting value, starting bids and bid increments

Each donor tells you the fair market value of the item. Record it, and put it on the bid sheet so guests can see what they are getting. Then set the starting bid and the raise.

A starting bid well under value invites the first bid and starts the competition. A starting bid at or above value usually draws no bids at all. A common starting point is between a third and a half of the stated value, adjusted up or down for items you expect to be popular. Set the minimum raise to a round figure that is easy to calculate, and make it larger for higher-value items so bidding does not take an hour to climb.

Consider a buy-it-now price on a few popular items. It gives a guest a way to end the competition and take the item home, and it caps the work of managing a long bidding war. Rules for charitable auctions, including the tax treatment of what a donor gives and a bidder pays, vary by place. Ask a tax adviser or the local authority rather than guessing.

Bid sheets or mobile bidding

Choose the bidding method for your audience, your venue and your volunteers. Many auctions use both: paper sheets at the tables, and a screen or phone for the larger items.

Whichever you choose, the display decides how many bids you get. A silent auction is a retail display for one evening. Guests should be able to see an item, read about it and bid within about thirty seconds, without a queue. Group items by category, place the most valuable pieces where the foot traffic is highest, and spread the tables so a few popular items do not jam one corner. Add a short card that tells the story of each item in two lines, light each table, number each item clearly and keep an aisle open for wheelchairs and strollers. Check your venue rules on tables, tape and wall fixings before the day.

• Paper bid sheets

  Cheap, familiar and reliable when the wifi is not. Each sheet needs the item, value, starting bid, raise and a row per bid. Close by drawing a line under the last bid at the stated time, and have a volunteer collect the sheets.

• Mobile bidding

  Guests bid from a phone, see the current price and get an alert when outbid. It removes illegible handwriting and crowding at the table, and it records every bid. It needs a good connection in the room and a short instruction card at each seat.

• Hybrid

  Use paper at the display and mobile for remote guests, or mobile for the whole room with a paper back-up if the network drops. Decide who owns the back-up before the doors open.

A timeline from first ask to final thank-you

Work back from the event date. Allow longer if your list of donors is short.

Closing, checkout and thank-yous

Most of the stress of a silent auction comes after the bidding stops. Plan the close as carefully as the display.

1. 1

   Close in waves

   Closing every item at the same moment makes a crowd and a long line. Close categories at staggered times, announced in advance, with a final call before each one.

2. 2

   Confirm each winner

   Match the winning bid to a named bidder before the guest leaves the room. Post winning numbers or send a message, so people know what they owe.

3. 3

   Keep checkout quick

   Use two or more stations, sorted by bidder number or surname, with the item list printed in advance. Take payment the same night where you can, and decide beforehand what happens to unpaid items.

4. 4

   Hand over or arrange delivery

   Have items boxed and labeled for pickup, and a clear note for experiences and certificates with redemption terms and expiry dates.

5. 5

   Thank everyone

   Thank donors, winners and volunteers within a week. Tell donors what their item raised, and name the cause that money supports. Keep a record for next year's ask.

What Eventdex covers for an auction

Eventdex is event and fundraising software, not an auction house. Its fundraising page lists auction management and silent auctions among its features: cataloging items, real-time bid updates and automated notifications, with attendees taking part on-site or online. It also covers registration and ticketing, online donations, a live donation display and donor recognition around the event.

The page does not describe how an auction winner pays, how bid increments are configured or how items are closed in waves. Ask about those in a demo if they matter to you, and plan the checkout in your own process until you have confirmed them.

• Auction management and silent auctions

  Item cataloging, real-time bid updates and notifications for on-site and online bidders.

  Fundraising event management software

• Registration and check-in

  Ticket tiers and VIP levels at registration, and guest lists with VIP tags. Bidder numbers are your own process.

• Seating for the dinner

  If the auction runs alongside a seated dinner, plan the tables with the seating tool.
