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.
