The question asked, verbatim: best payment processing for nonprofits

Brands named, in the order the engine gave

1. Stripe mentioned
   For most US nonprofits, the answer is Stripe at the nonprofit rate, sitting under a donation platform you don't pay for - plus PayPal as a second button and Square if you take money in person.
2. PayPal mentioned
   For most US nonprofits, the answer is Stripe at the nonprofit rate, sitting under a donation platform you don't pay for - plus PayPal as a second button and Square if you take money in person.
3. Square mentioned
   For most US nonprofits, the answer is Stripe at the nonprofit rate, sitting under a donation platform you don't pay for - plus PayPal as a second button and Square if you take money in person.
4. Zeffy mentioned
   Zeffy - if you're small or volunteer-run, start here.
5. EIN mentioned
   It is not automatic and not retroactive - email [email protected] with your EIN/determination letter.
6. ACH mentioned
   Also: Stripe ACH is 0.8% capped at $5, which is the single biggest savings available on four- and five-figure gifts.
7. Givebutter recommended
   Givebutter - my default recommendation for an all-in-one front end: donation pages, events, ticketing, auctions, text-to-give, peer-to-peer, and a basic CRM, with no platform fee and no monthly cost.
8. all-in-one recommended
   Givebutter - my default recommendation for an all-in-one front end: donation pages, events, ticketing, auctions, text-to-give, peer-to-peer, and a basic CRM, with no platform fee and no monthly cost.
9. PayPal Giving Fund mentioned
   Separately, PayPal Giving Fund takes 0% but pays out monthly and gives you much less donor data - fine for passive channels, bad as your main pipe.
10. Donorbox mentioned
    Donorbox - worth paying for if recurring giving is your core program;
11. Bloomerang mentioned
    CRM-bundled processing (Bloomerang Payments, Blackbaud, Classy) - only once you're past roughly $1M raised and the real cost is staff time reconciling systems, not basis points.
12. Blackbaud mentioned
    CRM-bundled processing (Bloomerang Payments, Blackbaud, Classy) - only once you're past roughly $1M raised and the real cost is staff time reconciling systems, not basis points.
13. Classy mentioned
    CRM-bundled processing (Bloomerang Payments, Blackbaud, Classy) - only once you're past roughly $1M raised and the real cost is staff time reconciling systems, not basis points.

The answer, as recorded

## Short version For most US nonprofits, the answer is **Stripe at the nonprofit rate, sitting under a donation platform you don't pay for** - plus PayPal as a second button and Square if you take money in person. Here's who I'd actually name, in order: **1. Zeffy** - if you're small or volunteer-run, start here. Genuinely 0% platform *and* 0% processing; they survive on an optional donor tip (prompted at checkout, with a "no thanks" option). Nothing else gets you 100% of a gift. Caveats: the tip prompt annoys some donors and boards, the feature set is shallower than competitors, and you're dependent on a company whose revenue is voluntary. ([Zeffy model](https://www.zeffy.com/home/research), [critical review](https://donorbox.org/nonprofit-blog/zeffy-reviews)) **2. Stripe (nonprofit discount)** - the best *processor* for anyone with a website or a developer. Eligible 501(c)(3)s get **2.2% + 30¢** instead of 2.9% + 30¢, if 80%+ of your volume is tax-deductible donations. It is not automatic and not retroactive - email [email protected] with your EIN/determination letter. Also: Stripe ACH is 0.8% capped at $5, which is the single biggest savings available on four- and five-figure gifts. Ticket and auction revenue stays at standard rates. ([Stripe for nonprofits](https://checkoutpage.com/blog/stripe-for-nonprofits), [how to apply](https://support.goodbricks.org/knowledge-base/apply-for-stripe-discount/)) **3. Givebutter** - my default recommendation for an all-in-one front end: donation pages, events, ticketing, auctions, text-to-give, peer-to-peer, and a basic CRM, with no platform fee and no monthly cost. Processing is 2.9% + 30¢, and most orgs recover it because donors can opt to cover fees. Best balance of "free" and "actually full-featured." ([pricing comparison](https://www.g2.com/compare/givebutter-vs-zeffy)) **4. PayPal, at the confirmed-charity rate** - not as your only processor, but always as a second option. Confirmed 501(c)(3)s pay **1.99% + $0.49**, cheaper than Stripe on anything over ~$25, and a meaningful share of donors will only give through a PayPal/Venmo balance. Separately, PayPal Giving Fund takes 0% but pays out monthly and gives you much less donor data - fine for passive channels, bad as your main pipe. ([PayPal charity rates](https://paypal.com/charities), [Giving Fund tradeoffs](https://givebutter.com/blog/paypal-giving)) **5. Donorbox** - worth paying for if recurring giving is your core program; the recurring-donor management, upgrade prompts, and form customization are more mature than the free tools. The free Standard tier adds a 1.75% platform fee on top of Stripe/PayPal processing; the Pro tier runs ~$139-150/month and lowers that. (Published numbers vary by source and region, so get a quote before committing. [Donorbox pricing](https://donorbox.org/pricing)) **6. Square** - for in-person only: galas, 5Ks, thrift shops, festival tables. **2.6% + 15¢**, no nonprofit discount, but the hardware and offline reliability are unbeaten and setup takes an afternoon. If you clear $250K+/year in card volume you can request custom pricing. ([Square fees](https://square.com/us/en/payments/our-fees), [nonprofit context](https://givebutter.com/blog/square-for-nonprofits)) **7. CRM-bundled processing (Bloomerang Payments, Blackbaud, Classy)** - only once you're past roughly $1M raised and the real cost is staff time reconciling systems, not basis points. You'll pay more per transaction for native donor-record sync. ([Bloomerang Payments](https://bloomerang.com/blog/new-feature-introducing-bloomerang-payments/)) ## The two things that actually move the needle Push **ACH/bank transfer** for gifts over ~$500 (0.8% capped at $5 vs. ~2.2% uncapped - that's $5 instead of $220 on a $10,000 gift), and add a **DAF/stock** path via FreeWill, Overflow, or Daffy for major donors, where the processing fee is effectively zero. Those two changes save more than any amount of shopping between the platforms above. One caution on the sources: this category is saturated with vendor-written "comparison" content - several results above are competitors reviewing each other. The rate figures I've cited are from the processors' own pricing pages where possible, but confirm current numbers directly before you sign.
