Zeffy
zeffy.comZeffy (formerly Simplyk) is positioned within Nonprofit Software as a fundraising platform that is entirely free for nonprofits to use. It is used by more than 10,000 nonprofit organizations across North America and is designed as a consolidated fundraising solution. Organizations pay no fees to use the platform, so a $1,000 fundraising total results in the nonprofit receiving the full $1,000, with no reductions.
The service applies zero platform, transaction, credit card, or hidden fees. It supports online donations, event ticketing, peer-to-peer fundraising, memberships, donor management, raffles, lotteries, and additional fundraising activities. Unlike many competing tools that retain a percentage of each donation, Zeffy passes 100% of donations to nonprofits and is funded through voluntary contributions from donors, allowing donors to know their entire contribution supports the intended cause.
