The answer, as recorded

## Short answer **Stripe (nonprofit rate) + Givebutter or Donorbox on top of it** is the default I'd recommend for most US nonprofits. Below is the fuller ranking, with the caveat that a lot of the "best of" content out there is written by the platforms themselves about their competitors - I've weighted accordingly. ### 1. Stripe, with the 501(c)(3) discount 2.2% + $0.30 instead of 2.9% + $0.30. It's not automatic - you email `[email protected]` with your EIN or IRS determination letter and confirm that >80% of your volume will be tax-deductible donations. Gala tickets, membership dues, tuition, and auction payments don't count toward that 80%, so if you're event-heavy you may not qualify. Available in the US, Canada, UK, EU, Australia, and NZ. This is the processing layer; you still want a donation front end on top of it. ([Stripe support](https://support.stripe.com/questions/fee-discount-for-nonprofit-organizations), [Givebutter](https://givebutter.com/blog/stripe-for-nonprofits)) ### 2. Givebutter - best all-around front end for orgs under ~$1M/yr 0% platform fee if you leave donor tipping on; 3% if you turn it off, plus ~2.9% + $0.30 processing. Includes a real CRM, event ticketing, and peer-to-peer, which is unusual at this price. Givebutter Plus is $29/mo for advanced tools. This is what I'd pick if you want one system rather than a stack. ([Givebutter](https://givebutter.com/alternatives/donorbox)) ### 3. Donorbox - if you want a plain, boring, reliable donation form No monthly fee on Standard, 2.95% platform fee (up to 3.95% on some features and on crypto/stock). Pro is $150/mo and drops the platform fee to 1.75-2%, which pencils out somewhere around $300-400K in annual online giving. Best for small orgs that want minimal setup and don't need a CRM. ([Donorbox review](https://nonprofitpoint.com/donorbox-review/)) ### 4. Zeffy - genuinely $0 to you, but read the fine print No fees at all to the nonprofit; Zeffy's revenue comes entirely from an optional tip prompted to your donor, defaulted around 15-17%. Roughly two-thirds of donors leave one. The recurring complaint in reviews is donor confusion - people don't always notice the tip or find the opt-out, and some read it as a surprise charge. If your donor base skews older or is fee-sensitive, that friction is a real cost even though it doesn't show on your statement. Great fit for very small, volunteer-run orgs where every dollar of overhead matters more than checkout polish. ([Zeffy reviews](https://www.zeffy.com/blog/zeffy-reviews), [critical take](https://givebear.io/blog/is-zeffy-really-free)) ### 5. PayPal Giving Fund - as a supplement, not your primary PayPal covers 100% of processing fees for enrolled charities, so it's the only true zero-fee option. The catch: it only applies to donations that come through PayPal's own charity/fundraiser surfaces, not your website checkout, payouts arrive on a delay, and you get limited donor data. Enroll for the free money, but don't build your program on it. ([Kindful](https://kindful.com/blog/best-nonprofit-payment-processors)) ### 6. Helcim - if you do significant in-person or high-volume card payments Interchange-plus pricing with volume discounts, which beats flat-rate once you're past roughly $50-100K/yr in card volume. Worth pricing out if you run a thrift store, clinic, or ticketed venue. ([Kindful](https://kindful.com/blog/best-nonprofit-payment-processors)) ### 7. GoFundMe Pro (formerly Classy) - only at enterprise scale Custom annual contract, genuinely best-in-class peer-to-peer and event fundraising. Not worth the cost below ~$5M/yr raised. ([MonkeyPod](https://monkeypod.io/articles/435-comparing_the_top_nonprofit_fundraising_software_solutions)) ## What I'd actually do Under ~$250K/yr online: **Givebutter with Stripe's nonprofit rate**, plus PayPal Giving Fund enrollment on the side. If you're tiny and truly can't absorb any fee, **Zeffy** instead - accepting the donor-tip tradeoff. Over ~$1M or heavy on peer-to-peer events: get quotes from **GoFundMe Pro** and compare against Givebutter Plus before signing anything annual. One thing worth knowing regardless of choice: the "donor covers the fee" checkbox typically gets 60-80% uptake and moves the needle more than a 0.7% rate difference does. Turn it on wherever your platform supports it. **Sources:** - [Stripe - Fee discount for nonprofit organizations](https://support.stripe.com/questions/fee-discount-for-nonprofit-organizations) - [Givebutter - Stripe for Nonprofits](https://givebutter.com/blog/stripe-for-nonprofits) - [Givebutter vs Donorbox pricing](https://givebutter.com/alternatives/donorbox) - [NonprofitPoint - Donorbox Review 2026](https://nonprofitpoint.com/donorbox-review/) - [Zeffy reviews from real nonprofits](https://www.zeffy.com/blog/zeffy-reviews) - [Givebear - Is Zeffy Really Free?](https://givebear.io/blog/is-zeffy-really-free) - [Kindful - 8 Best Nonprofit Credit Card Processing Options in 2026](https://kindful.com/blog/best-nonprofit-payment-processors) - [MonkeyPod - Comparing Top Nonprofit Fundraising Software](https://monkeypod.io/articles/435-comparing_the_top_nonprofit_fundraising_software_solutions)
