What it is
Zeffy (formerly Simplyk) is a fundraising platform for nonprofits. It charges no transaction fees and no platform fees — your nonprofit keeps 100% of every dollar donated.
How Zeffy stays free
Zeffy is funded by optional donor tips. At checkout, donors see a prompt asking if they'd like to leave a tip to support Zeffy. Donors can decline and your nonprofit still keeps the full donation. Zeffy reports that roughly two out of three donors leave a tip (zeffy.com).
What you can do with it
- Online donation forms (one-time and recurring)
- Event ticketing
- Peer-to-peer fundraising campaigns
- Memberships
- Auctions and raffles
- Online stores / merch
- In-person card payments via the Zeffy Tap to Pay app
- Donor management / CRM

Value to your nonprofit
You keep 100% of donations — no 2.9% + $0.30 transaction fees, no monthly platform fees. On $10,000 raised, that's roughly $600+ kept versus a typical processor.
