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 on top) - The best default for most nonprofits.
2. Pay recommended
   Verified 501(c)(3)s get a discounted rate of 2.2% + $0.30 instead of 2.9% + $0.30, it handles recurring gifts, Apple/Google Pay, and it integrates with basically every website and donation tool you'd bolt on later.
3. Zeffy recommended
   Zeffy - The one to look at first if you're small and fee-sensitive.
4. Form 990 recommended
   It also lacks sub-accounts, expense tracking, and Form 990 support.
5. Givebutter recommended
   Givebutter - Similar tip-funded model but a more polished all-in-one (campaigns, events, peer-to-peer, light CRM).
6. Donorbox recommended
   Donorbox - Best if you want strong recurring-donation tooling and embedded forms without building anything.
7. PayPal recommended
   PayPal (+ PayPal Giving Fund) - Worth having as a secondary option because a lot of donors simply trust it.
8. PayPal Giving Fund recommended
   PayPal (+ PayPal Giving Fund) - Worth having as a secondary option because a lot of donors simply trust it.
9. Bloomerang recommended
   Bloomerang or CharityEngine - Only once you're large enough that donor data is the real asset.
10. CharityEngine recommended
    Bloomerang or CharityEngine - Only once you're large enough that donor data is the real asset.
11. PayPal Nonprofit mentioned

The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd consider them: **1. Stripe (with a donation form on top)** - The best default for most nonprofits. Verified 501(c)(3)s get a discounted rate of **2.2% + $0.30** instead of 2.9% + $0.30, it handles recurring gifts, Apple/Google Pay, and it integrates with basically every website and donation tool you'd bolt on later. The catch: Stripe is a processor, not a fundraising platform - no donation pages, receipting, or donor CRM out of the box. You'll pair it with something. **2. Zeffy** - The one to look at first if you're small and fee-sensitive. It's genuinely $0 to you: Zeffy runs on Stripe and eats the processing fees, funding itself by asking your donors for an optional tip at checkout. Over 100,000 nonprofits, $2B+ processed. The real tradeoff is that the tip is pre-selected at a fairly aggressive default (~15-17% on gifts under $100), so some of your donors will pay it without quite realizing it, and some organizations aren't comfortable with that optics-wise. It also lacks sub-accounts, expense tracking, and Form 990 support. **3. Givebutter** - Similar tip-funded model but a more polished all-in-one (campaigns, events, peer-to-peer, light CRM). 0% platform fee when tips are on, 3% if you turn tips off, plus 2.9% + $0.30 card processing. Givebutter Plus is $129/mo if you need the advanced tier. Good middle ground between Zeffy's austerity and a full CRM. **4. Donorbox** - Best if you want strong recurring-donation tooling and embedded forms without building anything. Note the fee structure is stacked: a platform fee starting at 2.95% (down to ~1.6% on Premium) *on top of* processing. You can ask donors to cover fees, and roughly half do. Fine, but do the math against Stripe-direct. **5. PayPal (+ PayPal Giving Fund)** - Worth having as a *secondary* option because a lot of donors simply trust it. Nonprofit rate is **1.99% + $0.49** - cheapest percentage but the highest fixed fee, so it's bad for small gifts and good for large ones. PayPal Giving Fund is genuinely 0% fees, but you give up the donor relationship and data, so I'd use it only for one-off or campaign-specific giving, not as your main channel. **6. Bloomerang or CharityEngine** - Only once you're large enough that donor data is the real asset. Bloomerang bundles processing at 2.4% + $0.30 with a proper donor CRM; CharityEngine's subscription-billing tech is the strongest option specifically for sustaining recurring revenue at scale. Both are overkill for a small org. **Short version:** if you're under a few hundred thousand in annual online giving, Zeffy or Givebutter; if you want control and clean integrations, Stripe direct with a form layer; add PayPal as a second button either way. Skip the CRM-bundled processors until donor data management is an actual bottleneck. One caveat: several of these fee figures come from vendors comparing themselves to competitors, so verify the current rate on the provider's own pricing page before committing - these change.
