Auction software lets a charity run a fundraising auction online, at an event, or both, without bid sheets, spreadsheets, or chasing payments by hand. The right platform depends on what you are running: a one-off online auction to your supporter list, a gala with mobile bidding in the room, or a high-value art or experiences sale where your brand, your bidder data, and your final prices all matter.
This guide compares 15 auction platforms used by charities and non-profits in the UK, the US, and beyond. Each entry covers what the platform does, who it suits, its key features, and how it charges. Indy.auction leads the list for charities that want a fully branded auction on their own site, with bidder and underbidder data they keep, and no setup or subscription fees.
How this list was put together: Indy.auction publishes this guide and appears first. Every other platform is described from its own website and public software listings as of October 2026, in no particular order of preference. Features and pricing change, so check each provider's site before you decide.

Charity auction software runs the mechanics of a fundraising auction for you: listing lots, registering bidders, taking and tracking bids, notifying winners, and collecting payment. Most platforms support timed online auctions (often called silent auctions), and many also support bidding on phones at an in-person gala.
The platforms below fall into three broad groups. Some give you your own branded auction site. Some bundle auctions into a wider fundraising suite with donations, ticketing, and a donor database. Others are built around the gala night, with check-in, seating, and live auction tools.
These eight questions separate one platform from another more clearly than any feature list.
Some platforms run your auction on your own branded site and web address. Others host it on their own marketplace or under their own logo. If supporters know and trust your brand, a white-label auction keeps the focus on you.
Every registered bidder is a potential future supporter, including the underbidders who lost out on a lot. Check whether you can export contact details for all bidders, not just winners, and whether the export is GDPR-compliant.
Pricing usually follows one of four models: a percentage of funds raised, a fee per event, an annual subscription, or a free platform funded by optional donor tips. Some platforms let you pass the fee to the buyer, so the charity keeps the full hammer price.
An online-only auction reaches supporters anywhere and runs for days or weeks. A gala needs mobile bidding, check-in, and a live display on the night. Decide which you need before comparing features.
Last-second bids can stop other bidders responding, which can lower the final price. Look for automatic bidding extensions and a choice over whether lots close together or one after another.
Artists, galleries, and other donors may not want a lot's final sale price published, especially if it sold below market value. A hidden hammer price option protects those relationships and makes high-value donations easier to secure.
Look for card payments through a provider such as Stripe or PayPal, a clear checkout link for winners, and automatic payment reminders. Unpaid lots are one of the biggest sources of admin after an auction.
Self-serve platforms suit teams who are confident running the auction themselves. If you need help with lot sourcing, bidder checks, marketing, or a professional auctioneer, check whether the provider offers managed services alongside the software.
Best for: charities, museums, and arts organisations that want a fully branded auction, full ownership of their bidder data, and no upfront cost.
Indy.auction is a self-serve, white-label auction platform built by The Auction Collective, a London auction specialist whose team includes people from Christie's, Artsy, and eBay. Instead of listing your lots on someone else's marketplace, you run your own branded auction site, with your logo, colours, imagery, and terms and conditions, on your own custom subdomain. Setup needs no coding or auction experience: choose a template, upload your lots, and go live for bidding, often within minutes.
The platform is built around the details that decide how much a charity auction raises. Bidding extensions stop last-second sniping, proxy bidding lets supporters set a maximum and step away, and real-time bid updates keep competition moving without a page refresh. After the auction closes, you keep the contact data for every registered bidder, including underbidders, so the auction grows your supporter base whatever the result.
Indy.auction suits a fast online appeal as well as a flagship annual sale. Charities can launch an auction quickly in response to an unexpected high-value donation, or run a long-standing benefit auction alongside a live sale at a major auction house.

It depends on the auction. For a simple event-night silent auction, an all-in-one fundraising suite may be enough. For an auction where your brand, your bidder data, and the final prices matter, such as an art, experiences, or high-value lots sale, a white-label platform like Indy.auction gives you more control.
Yes, in several forms. Some platforms are funded by optional donor tips at checkout, some offer a free base tier with limits, and some charge only a percentage on lots that sell, so nothing is owed if nothing sells. On Indy.auction, you can pass the fee to buyers so the auction costs your charity nothing. Card processing fees usually still apply.
A traditional silent auction takes written bids on paper sheets at an event. An online auction, also called a timed auction, runs on a website for a set period, and supporters bid from any device. Many charities now run a timed online auction instead of, or alongside, bidding in the room.
Use a platform with bidding extensions. If a bid lands in the final minute, the closing time extends so other bidders can respond. Indy.auction lets you choose whether all lots close together, close in sequence, or close individually, each with its own extension.
On some platforms, yes. Indy.auction lets you hide final sale prices after the auction closes. This helps when artists or other donors would rather a lot's result was not public.
Usually not. A winning bidder receives goods or a service in return for their payment, so the payment is not a gift. Check HMRC's Gift Aid guidance, or ask your charity's adviser, before you plan around it.
Start with the auction you want to run, then work back to the software. If your auction requires ticketing functionality and gala management outside of the auction, then larger all-in-one solutions may be more suitable. On the other hand, any auction of artworks, experiences, or other high-value lots calls for control over your brand, your bidder data, and how results are shared. This is where Indy.auction excels.
With Indy.auction, you run the auction on your own branded site, keep the data for every bidder and underbidder, choose whether final prices are published, and pay nothing upfront.
