Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
Mightycause
Nonprofit fundraising with no monthly bill
Mightycause gives a nonprofit donation pages, peer-to-peer fundraising and event tools without a subscription, and it operates as a donor advised fund, which is what lets it handle receipting and the 501(c)(3) paperwork on the organisation's behalf. The company states an overall ceiling on what a donation costs rather than splitting platform and processing. There are no donor tip prompts. Anybody outside the United States is in the wrong place.
Our note
Work out your annual donation total and multiply, because a percentage-only model beats a subscription at low volume and loses at high volume, and this one is priced to win the first case. The donor advised fund arrangement is worth understanding before switching, since it changes who is technically receiving the gift.
Zeffy
Fundraising with no platform or processing fee
Zeffy takes nothing from a donation, and covers card processing itself out of the optional tips donors leave at checkout. Donations, ticketed events, raffles, auctions, memberships and a donor database are all in the same account. It is built for nonprofits, and the sign-up asks you to be one.
