The question asked, verbatim: best payment processing for nonprofits

Brands named, in the order the engine gave

1. Stripe recommended
   Stripe (with a donation form layer on top) - This is what I'd recommend to most nonprofits as the underlying processor.
2. Givebutter mentioned
   Givebutter - The best "all-in-one and effectively free" option.
3. all-in-one mentioned
   Givebutter - The best "all-in-one and effectively free" option.
4. Donorbox mentioned
   Donorbox - Pick this over Givebutter if recurring giving is your core program.
5. PayPal mentioned
   Platform fee is 1.75% on the free plan (1.5% on Donorbox Pro at $139/mo), and it rides on Stripe/PayPal so you can get their discounted nonprofit rates underneath.
6. PayPal Nonprofit mentioned
   (PayPal nonprofit fees (https://www.merchantmaverick.com/?p=71042))
7. Square mentioned
   Square - Specifically for in-person fundraising: galas, bake sales, merch tables, festival booths.
8. Google compared
   The hardware and offline-mode handling are better than anyone else's, and it takes tap/Apple Pay/Google Pay cleanly.
9. Zeffy mentioned
   Zeffy - Genuinely 100% free to the nonprofit, which is remarkable if you're tiny and every dollar counts.
10. Bloomerang Payments mentioned
    Bloomerang Payments or Blackbaud/Classy - Only if you're past roughly $1M in annual revenue and your real problem is donor data, not transaction cost.
11. Blackbaud mentioned
    Bloomerang Payments or Blackbaud/Classy - Only if you're past roughly $1M in annual revenue and your real problem is donor data, not transaction cost.
12. Classy mentioned
    Bloomerang Payments or Blackbaud/Classy - Only if you're past roughly $1M in annual revenue and your real problem is donor data, not transaction cost.
13. Wise mentioned
    I cross-checked the fee numbers above, but one result confidently named Wise as the "#1 pick," which is nonsense for donation processing - it's a currency-transfer service.

The answer, as recorded

## My actual picks, in order **1. Stripe (with a donation form layer on top)** - This is what I'd recommend to most nonprofits as the underlying processor. Eligible 501(c)(3)s get **2.2% + 30¢** instead of the standard 2.9% + 30¢, which is among the best rates you'll find without negotiating interchange-plus. The catch: Stripe is a processor, not a fundraising platform - no built-in donation pages, recurring-giving management, or receipting unless you add something. You have to email [email protected] to get the rate, and it generally requires ~80% of your volume to be tax-deductible donations. ([Stripe nonprofit rate details](https://wiredimpact.com/blog/stripe-for-nonprofits/)) **2. Givebutter** - The best "all-in-one and effectively free" option. No monthly fee, no platform fee if you leave optional donor tipping on; turn tipping off and it's 1% on donation forms, 3% on fundraising pages, 5% on events/auctions. Processing is 2.9% + 30¢. It covers donation forms, peer-to-peer, events, and auctions, plus a light CRM - so it replaces several tools at once. ([fee comparison](https://givebutter.com/blog/stripe-for-nonprofits)) **3. Donorbox** - Pick this over Givebutter if recurring giving is your core program. Platform fee is 1.75% on the free plan (1.5% on Donorbox Pro at $139/mo), and it rides on Stripe/PayPal so you can get their discounted nonprofit rates underneath. Stronger recurring-donor tooling and better form customization than most free options. ([Donorbox vs. Givebutter](https://donorbox.org/givebutter-vs-donorbox)) **4. PayPal** - Worth having *alongside* your main processor, not as your only one. The confirmed-charity rate is **1.99% + $0.49**, so it's the cheapest percentage out there but the worst on small gifts - a $10 donation loses ~6.5%. Many donors trust and prefer it, so it's a good secondary checkout option. ([PayPal nonprofit fees](https://www.merchantmaverick.com/?p=71042)) **5. Square** - Specifically for in-person fundraising: galas, bake sales, merch tables, festival booths. The hardware and offline-mode handling are better than anyone else's, and it takes tap/Apple Pay/Google Pay cleanly. Don't make it your online donation engine. **6. Zeffy** - Genuinely 100% free to the nonprofit, which is remarkable if you're tiny and every dollar counts. I rank it lower because of how it funds itself: a pre-selected optional donor tip of up to ~17%, which many donors don't realize is optional. That's a real donor-trust risk, and reviews mention pushback and tipping fatigue. Also no crowdfunding or text-to-give. ([Zeffy reviews, pros and cons](https://donorbox.org/nonprofit-blog/zeffy-reviews)) **7. Bloomerang Payments or Blackbaud/Classy** - Only if you're past roughly $1M in annual revenue and your real problem is donor data, not transaction cost. At that size the CRM integration is worth paying more per transaction for. ([Bloomerang Payments](https://bloomerang.com/blog/nonprofit-credit-card-processing)) **One worthwhile note:** if you're processing meaningful volume (say $500K+/year), stop comparing flat rates and get an **interchange-plus** quote from a merchant services provider. Flat 2.2% is a blended average that overcharges you on debit cards, which are a big share of donations. **A caveat on the research:** this question's search results are dominated by vendor content marketing - Donorbox ranks for "Zeffy reviews," Zeffy ranks for "PayPal fees," Givebutter ranks for "Stripe for nonprofits," and so on. I cross-checked the fee numbers above, but one result confidently named Wise as the "#1 pick," which is nonsense for donation processing - it's a currency-transfer service.
