What is an Online Silent Auction? 

Just like a traditional silent auction, an online silent auction is a fundraising strategy that lets donors bid on a collection of curated items over a set period. Bids are recorded anonymously on bid sheets and donors can bid on multiple items at once. 

The key difference? Online silent auctions take place entirely online using a designated auction website, platform, or mobile app. 

Participants browse lot photos, read descriptions, and place bids completely virtually. At the end of the event, the highest bidder on each item takes home the prize. 

Why Host a Silent Auction Online?

Save Money

Affordability is key when planning a fundraising event. With no need for a physical venue, auctioneer, or on-site staff, hosting a silent auction online saves your nonprofit significant costs. 

Drive More Funds

With no venue limitations, online silent auctions can stay open for longer than their traditional counterparts. That means you have more time to drive up bids on hot items or draw attention to prizes that aren't performing as well.

Expand Your Reach

By hosting your silent auction online, you open up bidding to donors across the world. Not only does this increase your fundraising potential exponentially, but it also broadens the reach of your organization further than ever before. 

Track Your Data

Auction software data is crucial to understanding your audience. With bidder profiles and data, you can pinpoint your demographics, hone your outreach campaigns, improve future fundraisers, and even connect with new donors. 

Your online silent auction platform is key to pulling off the entire fundraising event, so choosing the right one is a crucial first step.  

Remember, the platform you use will determine what your auction is capable of and should correspond with your event's unique needs.

Starting Bid Amount

As a rule of thumb, experts recommend setting your starting bid at 30-40% of an item’s fair market value. Increase this amount to 50% for high-ticket items such as vacation travel packages. 

Bid Increments

Most online silent auctions require a 10%-15% increase per bid to ensure bidding stays competitive and proceeds don’t stagnate.

Because bidders can’t see your items first-hand, a good presentation is crucial to promote trust and encourage bidding. Use the following auction item checklist to make sure your items are well-represented.

Item Descriptions

• Clear and concise blurb
• Grammatically correct
• No questions remain after reading

High-Quality Photos

• Clear with no pixelation
• Good lighting
• Avoid busy backgrounds
• Multiple photos

Important Information

• Opening bid amount
• Bidding increment amount
• Additional lot details (e.g. travel blackout dates)
• Conditions and regulations 

With your items lined up, it's time to start advertising your event! Social media and email are powerful tools to spread the word about your charity fundraiser. Be sure to include teasers of high-ticket items up for grabs. 

Attractive visuals go a long way in promoting your prizes and amplifying bids. Look for consignment companies such as LuxGive that offer professional fundraising marketing materials for all their packages. 

Take advantage of the excitement around your charity auction to open registration early. This allows you to streamline the onboarding process before you launch and catch any issues before event day. 

Using your online silent auction site or platform, donors can set up their bidder profiles and pre-register their credit cards. Some auction software even allows you to pre-assign bid numbers to your donors or open pre-bidding on select items! 

Congratulations, the big day is finally here! It's time to officially open your online silent auction to bidding. 

During the Auction

There are plenty of ways to help drive more engagement and keep donors bidding until the auction closes: 

• Automated Notifications: alert users when they've been outbid, sparking better bidding wars
• Gamify Options: utilize leaderboards, countdown timers, and thermometers to drive friendly competition
• Item Spotlights: showcase hot deal items on the platform or highlight items that need a boost
• Buy-Now Offers: sell multiples by offering a click-to-buy option on popular consignment items
• Social Media: live stream parts of the event online or keep up the momentum with announcements, shoutouts, and frequent updates

Note: these functions will depend on your choice of auction platform software. Remember to use the checklist in step 1 to determine your event needs.

Checking Out

No need to collect and sort through hundreds of bid sheets. Checking out is simple and quick for admins and donors alike. Winners are provided with payment links and those who pre-registered their credit cards are charged automatically. 

Unlike traditional auctions, online silent auctions can last for days or even weeks. Once a lot is closed and payment received, the best practice is to ship the item out as soon as possible. 

For experience-based items such as auction travel packages or chef service, be sure to connect vendors with lot winners so they can redeem their prize and arrange any further details. 

It might be the last step in your online silent auction, but it's one of the most important! Make sure to thank your donors for their participation and generosity. Your show of gratitude will go far in building donor relations and trust. 

Best Thank You Practices

• Personalize your thank you messages 
• Tell donors how the funds will support your mission
• Automate thank you notes via your auction platform
• Send a hand-written note to top supporters
