The answer, as recorded

# Best payment processing for nonprofits Here's who I'd actually name, in order. The right answer depends mostly on your size and whether you need a donation platform or just a processor. **1. Stripe - the default for most nonprofits.** Eligible US 501(c)(3)s get a discounted **2.2% + 30¢** rate when at least 80% of volume is tax-deductible donations (tickets, memberships, and auctions bill at the standard 2.9% + 30¢). Best APIs, best reliability, and nearly every donation platform plugs into it - so you're not locked in. Downside: you need some tech capacity to build a good donor experience, or you pair it with a platform.

PayPal (nonprofit rate) - add it alongside Stripe, don't replace it.** **1.99% + $0.49** for US 501(c)(3)s, so it's cheaper than Stripe above roughly $25 per gift and more expensive below it. The real argument is conversion: a lot of donors will complete a PayPal checkout who'd abandon a card form. Run both.

Zeffy - if you're small and fee-sensitive.** Genuinely $0 platform fees and $0 processing; they survive on optional donor tips (Zeffy says ~60% of donors tip, averaging ~4%; other sources claim higher). For a small org where 3% is real money, this is the cheapest option that exists. Caveat worth knowing: the tip prompt has drawn criticism for making opt-out non-obvious, so some of your donors will tip without quite meaning to. Decide if you're comfortable with that trade.

Givebutter - best all-in-one for mid-size orgs running campaigns and events.** Free CRM, donation forms, peer-to-peer, and events in one place. Pricing is tiered by tool: ~1% on donation forms, ~3% on fundraising pages, ~5% on events/auctions, plus 2.9% + 30¢ processing - but most of that is typically covered by donor tips, so effective cost is often near zero. [charitycharge.com/nonprofit-resources/givebutter-vs-zeffy](https://www.charitycharge.com/nonprofit-resources/givebutter-vs-zeffy/) **5. Donorbox - if recurring giving is your core program.** Strong recurring donation handling and clean embeddable forms. Platform fee runs ~2-5% depending on plan, on top of 2.9% + 30¢. Pricier than the above; justify it with the recurring-donor tooling, not the rate. [toolradar.com/compare/zeffy-vs-donorbox](https://toolradar.com/compare/zeffy-vs-donorbox) **6. An interchange-plus processor (e.g., eBizCharge) - only at high volume.** Once you're processing serious money, flat-rate pricing stops making sense and interchange-plus plus real ACH support saves meaningfully. ACH matters a lot: a $10,000 gift on a card costs ~$300 in fees, on ACH it's a few dollars. [ebizcharge.com](https://ebizcharge.com/?p=85319) **One I'd skip:** Square. 2.6% + 10¢ with no real ACH support and no nonprofit discount - fine if you already use it for in-person events, wrong as your primary donation rail. [goharness.com/blog-posts/square-alternatives-for-nonprofits](https://goharness.com/blog-posts/square-alternatives-for-nonprofits) **My actual recommendation:** small org → Zeffy or Givebutter. Mid-size → Givebutter or Donorbox on Stripe, with PayPal enabled. Large → Stripe at the nonprofit rate plus a dedicated ACH path for major gifts, and shop interchange-plus. And whatever you pick, turn on the "cover the fees" checkbox - a large share of donors tick it, which matters more than a 0.2% rate difference.
