The question asked, verbatim: best payment processing for nonprofits

Brands named, in the order the engine gave

1. Stripe recommended
   Stripe directly (2.2% + 30¢ with the nonprofit discount) - If you have any technical capacity or a website you control, this is the baseline everything else should be measured against.
2. EIN recommended
   Eligible 501(c)(3)s with an EIN get 2.2% + 30¢, but you have to apply - email [email protected].
3. Amex recommended
   The catch: over 80% of your Stripe volume must be tax-deductible donations, so ticket sales, memberships, and auctions get billed at standard rates, and Amex/international cards are excluded.
4. Zeffy recommended
   Zeffy - if you're small and fee-sensitive - Genuinely $0 platform fee and $0 processing fee;
5. Givebutter recommended
   Givebutter - best all-around if you want real fundraising tools - $0 platform fee, processing up to 2.9% + 30¢, and donors can elect to cover fees.
6. PayPal recommended
   PayPal (1.99% + 49¢ charity rate) - Worth having alongside a card processor rather than as your primary.
7. RallyUp recommended
   RallyUp - if you run raffles, auctions, or sweepstakes - 0% platform fee on donation and P2P pages, passes Stripe/PayPal fees through without markup.
8. Donorbox mentioned
   Who I'd skip: Donorbox at 3.95% + 30¢ (1.75% platform fee stacked on 2.2% Stripe) is hard to justify when Givebutter charges no platform fee for comparable tooling.
9. Square mentioned
   And Square at 2.6% + 10¢ is built for retail, not donations - no nonprofit rate, weak recurring-gift handling.

The answer, as recorded

# Payment processing for nonprofits The honest framing: you're paying two separate things - a **platform fee** (the fundraising software) and a **processing fee** (the card networks' cut, which nobody escapes). Most "best platform" advice conflates them. Here's what I'd actually recommend, roughly in order: **1. Stripe directly (2.2% + 30¢ with the nonprofit discount)** - If you have any technical capacity or a website you control, this is the baseline everything else should be measured against. Eligible 501(c)(3)s with an EIN get 2.2% + 30¢, but **you have to apply** - email [email protected]. The catch: over 80% of your Stripe volume must be tax-deductible donations, so ticket sales, memberships, and auctions get billed at standard rates, and Amex/international cards are excluded.

Zeffy - if you're small and fee-sensitive** - Genuinely $0 platform fee and $0 processing fee; they survive on optional donor tips (~15-17% of donation amount, ~80% of donors opt in). For a small org where every dollar matters, nothing else competes on cost. The real tradeoff is that your donors see a tip prompt at checkout - some boards hate that, and you're dependent on a company whose revenue model is donor generosity. ([zeffy.com](https://www.zeffy.com/blog/payment-gateway)) **3. Givebutter - best all-around if you want real fundraising tools** - $0 platform fee, processing up to 2.9% + 30¢, and donors can elect to cover fees. You get campaign pages, peer-to-peer, events, and a usable CRM. This is where I'd point most mid-size orgs that want features without a platform tax. ([g2.com comparison](https://www.g2.com/compare/donorbox-vs-givebutter-vs-zeffy)) **4. PayPal (1.99% + 49¢ charity rate)** - Worth having *alongside* a card processor rather than as your primary. The rate is excellent and some donors simply will not type a card number but will click PayPal. Confirm your charity status at [paypal.com/charities](https://paypal.com/charities). International donations add ~1.5%. ([societ.com](https://www.societ.com/?p=101868)) **5. RallyUp - if you run raffles, auctions, or sweepstakes** - 0% platform fee on donation and P2P pages, passes Stripe/PayPal fees through without markup. Narrower use case but good at it. ([rallyup.com](https://rallyup.com/?p=22698)) **Who I'd skip:** **Donorbox** at 3.95% + 30¢ (1.75% platform fee stacked on 2.2% Stripe) is hard to justify when Givebutter charges no platform fee for comparable tooling. And **Square** at 2.6% + 10¢ is built for retail, not donations - no nonprofit rate, weak recurring-gift handling. ([bloomerang.com](https://bloomerang.com/blog/nonprofit-credit-card-processing), [goharness.com](https://goharness.com/blog-posts/square-alternatives-for-nonprofits)) **Two things that matter more than the rate itself:** - **Recurring giving is where fees compound.** A 1.5-point difference is noise on a one-time $50 gift and significant on a $50/month donor over three years. Optimize for your recurring base. - **Ask whether donors can cover fees.** Givebutter, Zeffy, and most modern platforms offer this, and a meaningful share of donors say yes - which often matters more than shaving 0.4% off your rate. One caveat on the numbers above: these are the advertised rates as of now, and nonprofit discount terms (especially Stripe's 80% volume rule) change and get enforced unevenly. Verify your specific eligibility before switching anything.
