9 Best Online Auctions Software For Nonprofits in 2024 (Free & Paid)

What is Nonprofit Auction Software? 

Online auction software is a tool designed to manage and organize silent auctions. It seamlessly and efficiently handles item listing, ticketing, bidding, and the whole silent auction process. 

When it comes to choosing the right online auction platform, there are some essential features that you should look for to bring your silent auction ideas to life.

1. Mobile Bidding 

  • Automatic Bid Updates: ‍Automatically list each online auction item's current winning bid, the following minimum bid, the fair market value (FMV), and the buy-now price where necessary.
  • Push Notifications: Inform bidders about being outbid. Most online auction software either provides in-app updates or sends them via text/email.
  • Ability to Pay in-App: Simplify the payment process for your donors by ensuring your platform can save payment information and offer smooth check-out. 

2. Event Ticketing Features 

  • Generate automatic tickets for multiple attendees
  • Ability to customize the ticket
  • Manage RSVP from silent auction guests
  • Collect seating requests and guest names
  • Track silent auction guest dietary restrictions
  • Send automatic reminders to silent auction guests about the events

3. Check-out and Donations 

  • Secure Gateway: Regardless of your chosen software, ensure it uses a secure payment processing tool. Look for the payment card industry (PCI) compliance that ensures your donor's information is safe and your nonprofit reputation is intact.  
  • Multiple Payment Types: ‍Give your bidders the option to pay using various methods, including credit card and Apple Pay, and mark them as “paid” if they want to pay by cash or check.
  • Low Transaction Fees: ‍Choose a platform that charges no or little transaction fees so that you receive a large proportion of your donations. Zeffy is a 100% free nonprofit tool that allows you to receive the total donation amount your guests submitted.

4. Item Procurement and Planning 

  • Generate donation solicitation letters
  • Suggest items and unique experiences to include
  • Helps to identify recurring sponsors and donors
  • Track procurement status
  • Log item location
  • Bundle several items into packages
  • Generate descriptions for items
  • Group items by theme or category
  • Customize starting bids and raises 

5. Gamification Elements 

If you're planning virtual and hybrid events, consider auction software with gamification features to make your experience more exciting and inclusive for virtual guests. 

  • Live leaderboards showing auction items with the most bids and fundraising progress thermometers are remarkable ways to build momentum. 
  • Scoreboards and countdown clocks are incredible ways to speed up the bidding by sparking a feeling of urgency.
