The answer, as recorded

Here's who I'd actually point you to, roughly in order: **1. Stripe (with the nonprofit discount)** - 2.2% + $0.30 for verified 501(c)(3)s instead of the standard 2.9% + $0.30. This is my default recommendation if you have anyone technical (or a platform that plugs into it). It's the most reliable infrastructure, handles recurring giving and ACH well, and nearly every donation tool integrates with it. On $100K/year that discount alone saves ~$700. **2. Givebutter** - Best all-in-one if you don't want to build anything. Donation forms, events, peer-to-peer, and a basic CRM, and the platform itself can cost you $0 because it's funded by optional donor tips. The catch: donors see a tip prompt at checkout, and platform fees run 1-5% if you turn tips off. Great fit for small-to-midsize orgs. **3. Zeffy** - The genuinely zero-fee option, built only for nonprofits - donations, tickets, memberships, recurring, all with no cut taken from you. Same tradeoff as Givebutter but more aggressive: the donor-facing tip ask is prominent and defaults high, which some orgs find pushy. If your budget is tight and you're okay with that, it's hard to beat on pure cost. **4. PayPal (nonprofit rate)** - 1.99% + $0.49. Worth having *alongside* your main processor rather than as the only one, because a real slice of donors will only give through PayPal or Venmo. Note the high fixed fee: it's cheaper than Stripe on large gifts, worse on small ones - the crossover is around $85. **5. PayPal Giving Fund** - Separate from the above, and genuinely free: PayPal covers 100% of processing fees for enrolled charities. Restricted in how funds flow (disbursed monthly, donor data is limited), so treat it as a supplement, not your primary channel. **6. Square** - 2.6% + $0.10 in person, 2.9% + $0.30 online. Pick this if a meaningful share of your giving happens at galas, walks, or in-person events - the hardware and tap-to-pay experience is better than the alternatives. No nonprofit discount, though. **7. Helcim** - Interchange-plus pricing that typically beats Stripe and PayPal once you're above roughly $50K/month in volume. Only worth the switching cost at that scale. **8. Donorbox or Bloomerang** - If you want donor management bundled in. Donorbox is 2.95% platform fee on the free plan (or $150/mo Pro at 1.75-2%) *plus* processing; Bloomerang runs 2.4% + $0.30 with a real CRM behind it. Two things that matter more than the rate you pick: turn on **"donor covers the fees"** at checkout - a large majority opt in, which effectively zeroes out your cost - and offer **ACH/bank transfer** for gifts over ~$500, since it's usually capped around $5 instead of a percentage.
