💸
OneCause charges $2,995 a year for its Professional Auction & Event package, or 5% of funds raised on pay-as-you-go. Zeffy is 100% free, so every dollar raised goes to your mission, not software.
📆
OneCause is built for big events, not ongoing fundraising. Zeffy gives you donations, memberships, ticketing, and peer-to-peer in one place, year-round.
⚡
OneCause requires setup fees, training, and plan upgrades to unlock features. Zeffy is free to start, easy to learn, and built for small teams who need to fundraise now.
Yes. Zeffy is 100% free for nonprofits. We cover all transaction fees so you keep every dollar raised. Donors have the option to leave a voluntary contribution to support our platform.
Absolutely. Zeffy handles donations, memberships, ticketing, peer-to-peer campaigns, raffles, and auctions in one place. You get everything you need without paying for separate event packages.
You can start fundraising in minutes. Create your account, build your first form, and start accepting donations right away. No setup fees, no training required, no plan upgrades to unlock features.
You own your donor data and can export it anytime. Zeffy makes it easy to import your contacts and donation history so you can pick up right where you left off without losing any information.
OneCause publishes two options rather than one price, and they are alternatives rather than fees you pay together. Its Professional Auction & Event package is $2,995 a year. Its pay-as-you-go option starts at $200 and applies a 5% pay-later fee to funds raised, which OneCause says it caps, though it does not publish the cap amount. OneCause does not publish a payment processing rate. Zeffy is $0 either way, with no package to buy and no percentage of what you raise.
It depends which OneCause option you choose. On the $2,995 Professional package you pay $2,995 whether you raise $10,000 or nothing at all. On pay-as-you-go, a 5% pay-later fee on $10,000 comes to $500, before any payment processing costs, which OneCause does not publish. With Zeffy you pay $0 and keep the full $10,000.
OneCause was acquired by Bonterra in October 2025, and its own site now says "OneCause has joined forces with Bonterra." The product is still sold under the OneCause name, and review sites have started listing it as Bonterra OneCause. If you are comparing quotes, it is worth knowing you are buying into a larger suite. Zeffy stays what it is: one free platform, no tiers to move between.
Yes. BidPal was the company's original name, and it announced its rebrand to OneCause in January 2018, keeping the BidPal name on its mobile bidding product for a time. If you used BidPal for a silent auction, that is the same company you would be buying from today.
OneCause's published product list covers auctions and events, mobile bidding, ticketing, golf events, donation forms, Text2Give, peer-to-peer and personal fundraising pages. It does not list a donor CRM, grant tracking, volunteer management, or membership management, so nonprofits that need those usually run a second tool alongside it. Zeffy includes donor management and memberships in the same free platform.
Yes. Text2Give is one of OneCause's named products, sold as part of its online fundraising offering rather than priced separately on its site. Zeffy's donation forms can be shared by link or QR code from any campaign at no cost, with no add-on to buy.
Yes. Zeffy offers free auction tools with no annual contracts, setup fees, or training required. You can launch an auction in minutes and keep 100% of what you raise.
OneCause is primarily event-focused. If you need donations, memberships, ticketing, and auctions in one place year-round, Zeffy provides all of that at no cost.
Yes. Zeffy handles event ticketing, donations, and auctions with zero fees, making it a practical choice for churches and faith-based organizations that want every dollar to go toward their mission.
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.

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.
