Published March 2026. Updated regularly.
Picking the wrong auction software is an expensive mistake. You find out at the event — when mobile bidding lags, data doesn't sync, or your team is manually reconciling payments for days afterward. The right platform mostly disappears: bidders move through it easily, revenue flows into your CRM automatically, and your staff spends event night doing donor relations instead of troubleshooting.
This guide reviews the leading nonprofit auction software platforms in 2026 and explains what to look for before you sign a contract. We've organized platforms by their primary strengths, and we include a comparison table at the end to help you shortlist quickly.

What to Look for in Nonprofit Auction Software
Before reviewing platforms, it helps to know what actually differentiates them. Most tools advertise mobile bidding and easy setup. The real differences show up in how the platform handles data, payments, and the complexity of a live event.
Six Categories That Separate Good from Great
Evaluate every platform against these before you sign
One question that changes everything: Do you use Salesforce or Microsoft Dynamics as your CRM? If yes, how the platform connects to your CRM is the most important factor. Look for real-time sync — data that flows to your CRM immediately, not nightly batch exports or manual CSV imports that create reconciliation work.
The Platforms: Reviewed
Soapbox Engage Auctions
soapboxengage.com/apps/auctions
Soapbox Engage is purpose-built for nonprofits that run Salesforce or Microsoft Dynamics. Bid records, donor profiles, item history, and payment data sync directly to your CRM in real time, keeping your data clean and your team out of spreadsheets after the event.
The platform supports in-person, virtual, and hybrid auctions, with mobile bidding via a browser-based interface (no app download required). It handles silent and live auction formats, fund-a-need campaigns, ticket sales, and event registration from a single platform. Because everything syncs to Salesforce in real time, your auction history is immediately available for donor analytics, segmentation by bidding behavior, and building cultivation plans from actual data.
Soapbox also supports Microsoft Dynamics 365 for nonprofits that run on that platform.
Strengths
- Real-time Salesforce and Dynamics integration
- All revenue streams in one platform (auctions, donations, events, forms)
- Real-time bid visibility and outbid notifications
- Flexible post-event payment and invoicing
- Browser-based mobile bidding, no app download
- Long-term data ownership in your own CRM
- Live auction spotter tools
Considerations
- Best fit for Salesforce or Microsoft Dynamics users; less useful if you don't use either
Best for: Nonprofits that use Salesforce or Microsoft Dynamics and want bid and donor data synced to their CRM in real time, without manual reconciliation. Also strong for organizations running multiple revenue streams (auctions + donations + events) who want one platform, not three.
Soapbox Engage Auctions syncs every bid, donor record, and payment to Salesforce in real time. Purpose-built for nonprofit fundraising.
OneCause
onecause.com
OneCause (formerly BidPal) is one of the more established names in nonprofit auction software. It offers a comprehensive event fundraising suite that includes mobile bidding, live auctions, fund-a-need, peer-to-peer fundraising, and ticketing. The platform is designed for mid-size to large nonprofits running galas and major events.
OneCause integrates with Salesforce and other CRMs, though this is a data connection rather than a native build. Their event support and onboarding are frequently cited as strengths. Pricing is generally positioned at the higher end of the market.
Strengths
- Mature, full-featured platform
- Strong event-night support and onboarding
- Mobile bidding with real-time notifications
- Peer-to-peer fundraising built in
- Strong track record with large galas
Considerations
- Higher price point; can be cost-prohibitive for smaller events

- Contract and pricing require a sales conversation
Best for: Established nonprofits running large annual galas who want a full-service partner and are prepared to pay a premium for it.
GiveSmart
givesmart.com
GiveSmart is a well-known event fundraising platform with roots in mobile bidding. Originally part of Community Brands and now under Momentive Software, it covers auctions, fund-a-need, peer-to-peer, and donation campaigns. The platform emphasizes ease of setup for event coordinators without technical backgrounds.
GiveSmart connects to Salesforce and other CRMs through integrations. The platform has grown significantly through acquisition, which means the product surface is broad.
Strengths
- Intuitive setup for non-technical staff

- Fund-a-need and donation campaign support
- Dedicated support team
- Large existing customer base
Considerations

Handbid
handbid.com
Handbid is a mobile bidding-focused platform with a reputation for a clean bidder experience. It was built specifically for silent auctions and offers a native app for iOS and Android in addition to web-based bidding. The platform handles silent auctions, live auctions, fund-a-need, and ticket sales.

Strengths
- Clean, well-designed bidder UI
- Native iOS and Android apps
- Competitive pricing for the feature set
- Good silent auction mechanics
- Responsive customer support

Auctria is one of the most affordable auction platforms on this list. It covers silent and live auctions, online bidding, ticketing, and donation collection. For smaller nonprofits or organizations running their first auction, the price-to-features ratio is strong.
The platform is not designed around deep CRM integration. Some data export to tools like Little Green Light is available, but there is no direct Salesforce connection. The free tier is limited to events raising $10K or less per year.
Strengths

RallyUp
rallyup.com
RallyUp supports a wide range of fundraising formats including auctions, raffles, crowdfunding, peer-to-peer, sweepstakes, and more. It is built for organizations that want a single platform for multiple fundraising types across the year, not just events. The platform is free to use with an optional platform fee model where supporters can cover costs.
RallyUp's auction features are functional, but auction is one of many features rather than a core specialization. CRM integration is more limited than auction-focused platforms.
Strengths
- Free to use (optional platform fee model)
- Multiple fundraising types in one tool
- Good for organizations mixing auctions with raffles and crowdfunding
- Easy to set up quickly
Considerations
- Auction is not the primary focus; features are less deep

Givebutter
givebutter.com
Givebutter is an all-in-one fundraising platform that added auction functionality as part of a broader product expansion. It covers donations, events, peer-to-peer, live streaming, and auctions in a single platform, with a free-to-use model supported by optional donor tips.
The platform is best known for individual giving and peer-to-peer fundraising. Auction features were added more recently and are less mature than platforms purpose-built for event auctions. CRM integration is available through Zapier-style connections, not native to Salesforce.
Strengths
- Free platform with tip-based model
- Strong for small-to-mid fundraising campaigns
- Modern, clean interface
- Good for organizations new to digital fundraising
Considerations

32auctions.com
32auctions is one of the most basic and affordable options on this list. It is a simple online auction tool with a free tier that allows nonprofits to run small-scale online auctions quickly. There are no event management features, no CRM integrations, and no mobile bidding in the sense of a live event tool. It is essentially a digital bidding sheet.
Strengths

Considerations

How to Choose the Right Platform
The right platform depends almost entirely on how your organization manages donor data and how complex your events are. Here are three decision paths that cover the majority of nonprofits evaluating auction software:
Three Decision Paths
On pricing: Most platforms don't publish their rates — they require a sales conversation. When comparing bids, ask for the total cost model: platform fee + transaction fees + any per-event charges. A lower platform fee with higher per-transaction rates can cost more than a higher subscription depending on your volume. For Soapbox Engage pricing, visit soapboxengage.com/pricing.
The Bottom Line
Most auction platforms will run a serviceable silent auction. The differences become clear when you're managing a live auction, handling multi-revenue event night, or trying to build a long-term cultivation strategy from your auction data afterward.
If your organization runs on Salesforce or Microsoft Dynamics, the integration quality matters considerably. Real-time sync keeps your data clean, your workflows unified, and your post-event analysis actionable. For everyone else, the right platform depends on event complexity, budget, and how much you care about what happens to that data after the paddles come down.
