MonthFund vs. Zeffy
MonthFund vs. Zeffy:
Transparent fees vs. donor tips.
Zeffy is a solid general-purpose nonprofit platform. But it does not support pick-a-date calendar fundraisers, and it funds itself through donor tips. MonthFund is the specialist for the calendar model, with honest, disclosed pricing.
No credit card required. Free to start.
Two different models
MonthFund charges a clear, disclosed infrastructure fee on each donation. Donors see exactly what they are paying and can cover it in one click. Your donors give to you, not to our software.
Zeffy is free for organizers. To fund their platform, they show donors a default tip at checkout, often 10 to 15 percent. On a $10,000 campaign, that is up to $1,500 going to Zeffy rather than your cause. Most donors do not realize this until after they give.
Why organizations choose MonthFund
Built for the calendar fundraiser. Nothing else.
Zeffy does not support calendar fundraisers
Zeffy covers donation forms, events, peer-to-peer, and memberships. It does not offer a pick-a-date or 31-day calendar fundraiser format. If the calendar model is your primary fundraiser, MonthFund is the only purpose-built option.
No surprise tips for your donors
Zeffy asks donors for a platform tip at checkout, typically defaulted at 15 percent. MonthFund charges a clear 3% infrastructure fee that donors can see and choose to cover. Your donors give to your cause, not to our software.
Tools built for the 31-day format
MonthFund includes individual participant calendar pages, automated fill-rate reminders, live day-by-day tracking, and campaign-over-campaign reporting. All of it is built specifically for the 31-day format. None of it exists in Zeffy.
Predictable take-home for your org
With Zeffy, your take-home depends on how many donors tip. With MonthFund, the math is calculable before you recruit a single participant. A fully funded calendar at 3% is predictable. Tip-dependent revenue is not.
