Coverage: Claude (Anthropic) with web search. Other engines not included.

The question asked, verbatim: best payment processing for nonprofits. This page records one answer on one date. It is a measurement, not a ranking and not a recommendation.

Brands named, in the order the engine gave

1. Stripe compared
   Stripe - the default processing engine.
2. Zeffy compared
   the standard 2.9% + $0.30, and it's the processor sitting underneath most donation platforms anyway (Zeffy runs on it).
3. Givebutter compared
   Givebutter - best all-in-one for most small/mid nonprofits.
4. Donorbox compared
   Donorbox - best if recurring giving is the whole point.
5. PayPal compared
   Platform fee 1.75%-3.95% on top of Stripe/PayPal processing, so it's genuinely more expensive than #2 and #3 - worth it mainly if the recurring-giving UX and embeddability move your numbers.
6. Bloomerang compared
   Bloomerang - when donor retention matters more than fee shaving.
7. Classy compared
   Classy (now GoFundMe Pro) or Blackbaud - enterprise only.
8. Square compared
   Square - only for in-person.

The answer, as recorded

Searched current pricing and comparisons. Here's how I'd actually rank them, roughly in the order I'd try them: **1. Stripe - the default processing engine.** Verified 501(c)(3)s get a discounted rate of **2.2% + $0.30** vs. the standard 2.9% + $0.30, and it's the processor sitting underneath most donation platforms anyway (Zeffy runs on it). Best reliability, best payout behavior, supports Apple/Google Pay and recurring billing, integrates with essentially every CMS and donor tool. The catch: Stripe alone gives you a payment rail, not a donation form or receipting - pair it with one of the platforms below. ([wildapricot.com](https://www.wildapricot.com/blog/payment-processing-for-nonprofits), [givebutter.com](https://givebutter.com/blog/stripe-for-nonprofits)) **2. Zeffy - if fees are your binding constraint.** True $0 take rate: no platform fee, no processing fee, open to any registered 501(c)(3) without an application review. It's funded by optional donor tips at checkout, which is the real tradeoff - your donors see a tip prompt, and some will find it confusing. Also thin on restricted-fund tracking, audit-ready reporting, and clean accounting exports. Great for small and mid-size orgs collecting donations and event payments; you'll outgrow it if you have grants, multi-program budgets, or a board wanting real financials. ([zeffy.com](https://www.zeffy.com/blog/zeffy-reviews), [capterra.com](https://www.capterra.com/p/220131/Zeffy/reviews/)) **3. Givebutter - best all-in-one for most small/mid nonprofits.** Turn donor tips on and you pay **$0 platform and $0 processing**; turn tips off and it's a flat 3% platform fee plus processing (1.9%-2.9% + $0.30). You get forms, campaigns, peer-to-peer, events, and a usable built-in CRM in one place, which is more product than Zeffy for a similar cost structure. ([donorbox.org](https://donorbox.org/givebutter-vs-donorbox)) **4. Donorbox - best if recurring giving is the whole point.** Strong, well-tested recurring donation forms and donor-covers-fees logic. Platform fee 1.75%-3.95% on top of Stripe/PayPal processing, so it's genuinely more expensive than #2 and #3 - worth it mainly if the recurring-giving UX and embeddability move your numbers. ([donorbox.org](https://donorbox.org/pricing)) **5. PayPal - add it, don't build on it.** Confirmed nonprofit rate of **1.99% + $0.49** (vs. 2.89% + $0.49 standard), plus ~1.5% on international. The percentage is the lowest here, but the $0.49 fixed fee makes it bad for small gifts - on a $20 donation that's worse than Stripe. Its value is conversion: some donors will only give through a PayPal balance. Offer it as a second button. ([zeffy.com](https://www.zeffy.com/blog/paypal-donation-fees-for-nonprofits), [donorbox.org](https://donorbox.org/nonprofit-blog/paypal-nonprofit-donation-fees)) **6. Bloomerang - when donor retention matters more than fee shaving.** Published pricing ($125-$249/mo) with integrated processing at 2.4% + $0.30; gifts and donor profiles update in one system, so you stop reconciling a payment tool against a CRM. Right call once you're mid-size and managing relationships, not just transactions. ([getholdings.com](https://getholdings.com/resources/guides/best-payment-processing-nonprofits), [softwareadvice.com](https://www.softwareadvice.com/nonprofit/bloomerang-profile/vs/the-raisers-edge/)) **7. Classy (now GoFundMe Pro) or Blackbaud - enterprise only.** Custom processing rates, significant platform fees (roughly 5-8% for Classy), and Blackbaud budgets commonly running $4K-$20K/year per module plus implementation. Only justifiable above roughly $1M in annual online fundraising or complex campaign/federation structures. ([grantpipe.com](https://grantpipe.com/compare/versus/blackbaud-vs-bloomerang/), [getalignmint.org](https://www.getalignmint.org/blog/blackbaud-pricing)) **8. Square - only for in-person.** Worth knowing: **Square offers no nonprofit discount**; you pay the standard 2.6% + $0.10 in person, with custom rates negotiable only above ~$250K/year in card volume. Fine as the terminal at your gala, wrong as your online donation stack. ([zeffy.com](https://www.zeffy.com/blog/square-for-nonprofits), [merchantmaverick.com](https://www.merchantmaverick.com/square-for-nonprofits/)) Two things that matter more than the pick itself: turn on **donor-covers-fees** (a large share of donors opt in, which erases most of this math), and file the nonprofit-rate application with whichever processor you choose - the discounts above are not automatic on 501(c)(3) status alone.
