   PayPal Giving Fund covers 100% of fees from a separate pool, but you give up branding control and you don't get donor contact info on every gift, which makes it bad as a primary channel and fine as a supplement.

The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd consider them: ## 1. Stripe (with the nonprofit discount) 2.2% + 30¢ for verified 501(c)(3)s, vs. the standard 2.9% + 30¢. This is my default answer. It's the most reliable processor, has the best API and the widest integration support, and almost every donation tool on this list sits on top of it anyway. You have to apply for the nonprofit rate - it isn't automatic. ## 2. Givebutter $0 platform fee and $0 processing fee under their "Givebutter Guarantee" - funded by optional donor tips at checkout. It's a genuinely full package: donation pages, peer-to-peer, events, auctions, and a basic CRM. Best all-around pick for a small-to-midsize org that wants one tool instead of four. Note the advanced CRM/automation moved behind Givebutter Plus, from $29/mo priced by contact-list size. ## 3. Zeffy The other zero-fee option, also tip-funded, and built only for nonprofits - donations, memberships, ticketing, recurring gifts. Pick this over Givebutter if your priority is purely "keep 100%" and you don't need the fundraising/CRM depth. The real cost of both: donor tips shave down the average gift, and you're locked into their checkout. ## 4. PayPal 1.99-1.9% + 30-49¢ nonprofit rate, monthly fee waived for 501(c)(3)s. I'd add this alongside whatever you pick as primary, not instead of it - a meaningful share of donors, especially older ones, simply prefer PayPal and will abandon a form without it. **PayPal Giving Fund** covers 100% of fees from a separate pool, but you give up branding control and you don't get donor contact info on every gift, which makes it bad as a primary channel and fine as a supplement. ## 5. Donorbox 2.95% platform fee on the free tier (higher for events/crypto/stock), plus processing. Worth the money specifically if recurring giving is your focus - it's the strongest of these at monthly donor management, multi-currency, and CRM integrations. Pro at $150/mo drops the platform fee to 1.75-2%, which pencils out past roughly $150-200K/year. ## 6. Square 2.9% + 10¢ online, 2.6% + 10¢ in person. Use it for the in-person side - galas, merch tables, events. No special nonprofit rate, but the hardware and POS are the best in class. ## One thing worth more than the platform choice Push major and recurring donors to **ACH/bank transfer**. Card processing runs 2-3% ($20-30 on a $1,000 gift); ACH is a flat $0.25-$1.00. Stripe, Donorbox, and Givebutter all support it. For an org taking large gifts, steering those to ACH saves more than any platform switch will. **Short version:** small org, want it free and simple → Givebutter. Recurring-giving-heavy → Donorbox. Any technical capacity or a custom site → Stripe direct. Add PayPal in all three cases.
