Zeffy is a specialized fundraising platform designed exclusively for nonprofits who want to keep 100% of their donations. Instead of charging platform fees or taking a cut of credit card transactions, the system relies on voluntary tips from donors. You can manage everything from simple donation forms and peer-to-peer campaigns to complex event ticketing and lottery management without worrying about hidden costs or monthly subscriptions. You can easily track your donor database, automate tax receipts, and sell memberships or merchandise through a single dashboard. It solves the common problem of losing 3-5% of every gift to processing fees, making it an ideal choice for small to mid-sized charities, schools, and community groups looking to maximize their impact. The platform is accessible to any registered nonprofit in North America looking for a transparent, zero-cost financial solution.
