Zeffy
Zeffy's model sounds too good to check out, and mostly checks out: donation forms, event ticketing, raffles, memberships, and a donor CRM at genuinely zero cost - even card processing fees are covered, funded by optional tips donors add at checkout. The tip prompt itself is the honest caveat, and feature depth trails the paid enterprise platforms. For fee-squeezed small nonprofits, the math is hard to argue with.
Why we rate it
- Actually 100% free - no subscription, no platform cut, and processing fees are covered too
- Covers the whole toolkit: donation forms, ticketing, peer-to-peer, raffles, memberships, tax receipts
- Built-in donor management spares tiny teams a separate CRM subscription
Keep in mind
- The donor tip pre-selected at checkout confuses some donors - plan to explain it or field the occasional complaint
