BiddingOwl and Jumblebee help you run charity auctions, but they charge fees that reduce what you raise for your cause. Zeffy gives you auction tools plus donation forms, event ticketing, and donor management — all with zero fees so every dollar stays with your mission.
Zeffy is trusted by 50,000+ nonprofits


Bidding Owl VS Jumblebee

💸
Keep 100% of your auction proceeds instead of losing hundreds to platform fees. Your gala auction raises money for your mission, not their profits.
🎯
Run auctions, raffles, ticket sales, and donation campaigns all in one place. No need to juggle multiple platforms or pay separate fees for each tool.
🤝
Get real-time help from our team whenever you need it. No waiting for responses or paying extra for phone support during your events.
With Zeffy, you keep 100% of your auction proceeds. BiddingOwl takes 5% plus card fees, while Jumblebee charges 7.5% plus card fees. On a $10,000 auction, that's $500-750+ you lose to fees with other platforms but keep with Zeffy.
Zeffy provides unlimited email support and comprehensive resources to every nonprofit at no extra cost. BiddingOwl and Jumblebee limit phone support to premium plans only, leaving smaller nonprofits with basic email help when they need guidance most.
Unlike BiddingOwl (5% + card fees) and Jumblebee (7.5% + card fees), Zeffy charges zero platform fees on your auction proceeds. Every dollar raised goes directly to your cause, with donors having the option to leave a voluntary contribution to support our platform.
Yes. While BiddingOwl and Jumblebee focus mainly on auctions, Zeffy offers a complete fundraising toolkit including donations, ticketing, raffles, peer-to-peer campaigns, and online stores. Run your entire fundraising strategy from one platform without paying multiple fees.
Zeffy provides unlimited email support and comprehensive help resources at no extra cost. Unlike BiddingOwl and Jumblebee, which limit phone support to premium plans only, we're committed to helping every nonprofit succeed regardless of their budget or plan level.
Zeffy is the fundraising platform that cuts out the fees, clears up your tech mess, and puts your cause first — so your team, even if you're a small team wearing many hats or a one-person show, can focus on what really matters.
No platform fees. No processing fees. No catch. We know it sounds too good to be true, but it's not. Every penny goes straight to your mission, while competitors take 2-3% off every donation.

Stop bouncing between MailChimp, Eventbrite, and all those spreadsheets. Now you can handle donations, ticket sales, memberships, raffles, and all your donor info in one spot.
Built for teams like yours — whether you're volunteer-led or have limited staff. Set up donation forms, sell tickets, and launch campaigns without needing a tech wizard. It's super easy, and you'll be up and running in minutes.


From QR codes on flyers to Tap-to-Pay on a phone, Zeffy makes it easy to accept donations on the go. Mobile-optimized and offline-ready, so no donor slips through the cracks.
Centralize supporter relationships, automate thank-you messages, and preserve institutional knowledge when board members rotate out.

As a startup nonprofit with only two members, and no funding (yet) we’d need something with low (or no) fees. Zeffy was a dream come true.
