“We were incurring a ton of fees for our past fundraising platform and Zeffy has helped us receive so much more of our donations.”

Zeffy has been invaluable in helping me track our donors, sales, events, and revenue in one spot. The coolest thing about Zeffy is it really is free!

Everything about Zeffy suits us starting with (of course, NO fees) but also the ease of use and customer experience as well as their client support!!

Zeffy is very easy to use and ensures that every dollar quickly gets into our account.. A huge help to our work!

Zeffy is very simple, allows for a lot of customization and seamlessly integrates into our website. The fact that all of this is free is still wild to me.

We couldn't believe there was a free payment platform for our Girl Scout group. Zeffy took ZERO fees from us, which is huge when you run on very small amounts of money.

We were ready to sell tickets in less than 30 minutes. The reporting capabilities were better than some other paid-for sites.

Since using Zeffy, our conversion rate of donations has skyrocketed. It's an easy platform to use. Plus customer support has always been responsive and helpful!
