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.
