The answer, as recorded

Here's how I'd actually rank them, depending on where you sit: **1. Stripe - the default if you want a real processor you won't outgrow.** 2.9% + 30¢ standard, but eligible 501(c)(3)s get **2.2% + 30¢** - the catch is you have to run ~80% of your donations through Stripe to qualify. Best API, best reliability, works globally, and nearly every fundraising platform plugs into it. Downside: Stripe alone gives you no donation pages, no receipts, no donor CRM - you'll bolt something on top. ([givebutter.com/blog/stripe-for-nonprofits](https://givebutter.com/blog/stripe-for-nonprofits)) **2. Zeffy - if you're small and fee-sensitive, this is genuinely hard to beat.** $0 platform fee, $0 processing, $0 monthly. They cover card costs and survive on optional donor tips at checkout (donor can set it to $0). Covers donations, events, raffles, and memberships. Two honest caveats: your donors are being asked to subsidize you, which some boards dislike, and most of the glowing Zeffy-vs-everyone comparisons out there are published by Zeffy itself. ([zeffy.com/home/free-online-fundraising-platform](https://www.zeffy.com/home/free-online-fundraising-platform)) **3. PayPal - cheapest published percentage, and some donors simply trust it more.** Confirmed charity rate of **1.99% + $0.49**, monthly fee waived for registered 501(c)(3)s. The 49¢ fixed fee means it loses to Stripe on small gifts and wins on large ones. Worth having as a *secondary* option regardless - a meaningful slice of donors will only give via PayPal. ([rallyup.com/learn/paypal-vs-stripe-which-payment-processor-is-best-for-nonprofits](https://rallyup.com/learn/paypal-vs-stripe-which-payment-processor-is-best-for-nonprofits/)) **4. Givebutter - best if you want the whole fundraising stack, not just a pipe.** 2.9% + 30¢ cards, 1.9% + 30¢ ACH, with donor tipping to cover it; if you turn tips off you pay a 1-5% platform fee instead. You get campaign pages, peer-to-peer, events, and a CRM included, and you can accept PayPal inside campaigns without extra platform fees. ([givebutter.com/alternatives/paypal](https://givebutter.com/alternatives/paypal)) **5. Square - only for in-person.** 2.6-2.9% with free POS hardware-adjacent tooling. Galas, bake sales, merch tables, mobile card readers. Not what I'd pick for your recurring online giving. ([wildapricot.com/blog/payment-processing-for-nonprofits](https://www.wildapricot.com/blog/payment-processing-for-nonprofits)) **Who I'd skip: Donorbox.** The standard plan stacks a 2.95% platform fee on top of Stripe's 2.2% + 30¢, so you're near 5.15% all-in, plus monthly fees that scale up to $150. You're paying a lot for pages you can get free elsewhere. ([nonprofitpoint.com/best-donation-platforms-for-nonprofits](https://nonprofitpoint.com/best-donation-platforms-for-nonprofits/)) **The practical answer for most nonprofits under ~$250K/year:** Zeffy or Givebutter as your front end, with PayPal enabled as a second button. Once you're past that and have real dev capacity or need custom flows, move to Stripe at the 2.2% nonprofit rate and build on it. One thing to check before committing: ACH/bank-transfer support. At 1.9% or less with no percentage ceiling, pushing your major and recurring donors to ACH saves more money than any of the platform choices above.
