The answer, as recorded

# Best payment processing for nonprofits The key thing to understand first: **there are two separate fees** - the payment processor (Stripe/PayPal, who actually moves the money) and the platform (the donation form/CRM layer on top). Many "cheap" platforms make it up on one side or the other, so compare the all-in cost per $100 gift. Here's who I'd actually name, in order: ## 1. Stripe (with the nonprofit discount) - the default answer for most **2.2% + 30¢** for eligible 501(c)(3)s, down from 2.9% + 30¢. The catch: at least 80% of your Stripe volume has to be tax-deductible donations to qualify. Best recurring-donation infrastructure in the business, clean API, and nearly every nonprofit platform integrates with it - so you're not locked in. If you have any technical capacity at all, start here. [Stripe nonprofit rates](https://www.zeffy.com/blog/stripe-for-nonprofits) · [Stripe for nonprofits overview](https://checkoutpage.com/blog/stripe-for-nonprofits) ## 2. PayPal for Nonprofits - the cheapest percentage, and donor trust **1.99% + $0.49** for approved nonprofits vs. 2.89% + $0.49 standard. Lowest rate of the mainstream options, and a lot of older donors simply trust the PayPal button more than a card form. The 49¢ fixed fee means it loses to Stripe on small gifts (on a $10 donation PayPal takes ~69¢ vs. Stripe's ~52¢), so the real answer is usually **run both** and let donors pick.

Zeffy - if you're small and budget is genuinely the constraint **Truly $0** - no platform fee, no processing fee. They cover it by asking donors for an optional tip at checkout (~80% tip, averaging 15-17%). 50,000+ nonprofits use it. Real downsides: you're letting a third party solicit your donors on your checkout page, no crowdfunding or text-to-give, weak team permissions, and refunding the tipped portion is awkward. For a small org where 3% actually matters, the tradeoff is usually worth it. [Zeffy reviews, pros and cons](https://donorbox.org/nonprofit-blog/zeffy-reviews) ## 4. Givebutter - best free-ish all-in-one with real features **2.9% + 30¢** cards, **1.9% + 30¢** ACH, with the platform fee covered by donor tips - but if you turn tips off, you pay a **1-5% platform fee** instead. Strong on events, peer-to-peer, and campaign pages. Good middle ground between Zeffy's bare-bones free and a paid platform. [Givebutter vs Stripe fees](https://paymentproviders.io/compare/stripe-vs-givebutter?focus=fees) ## 5. Donorbox - good forms, but watch the stacking **2.95% platform fee on the Standard plan, on top of** Stripe/PayPal processing - and it jumps to **3.95%** if you use ticketing, peer-to-peer, or memberships. That's a real ~5-6% all-in. Worth it only if the forms and donor management save you staff time you'd otherwise pay for. [Donorbox fee structure](https://betterworld.org/blog/nonprofits/top-nonprofit-fundraising-software-alternatives-to-donorbox-in-2026/) ## 6. Bloomerang - if you need a CRM more than a checkout Subscription, not per-transaction: CRM from **~$125/mo** annually, Fundraising from **~$40/mo** bundled. Makes sense once donor relationship management is the actual bottleneck. Processing is separate on top. [Bloomerang pricing](https://toolradar.com/compare/bloomerang-vs-donorbox) ## 7. Classy (Bonterra) - enterprise only **$2,000-$8,000 setup plus $3,000-$15,000/year.** Only pencils out above roughly $2M raised annually, and you want dev resources. Don't look at this if you're under that. [Classy cost estimates](https://projectcostestimator.com/blog/nonprofit-fundraising-platform-cost-2026) ## Two I'd skip - **Square** - 2.6% + 10¢ with **no nonprofit discount** and no fundraising-specific features. Fine for an in-person bake sale or gala card reader, wrong for your main donation flow. [Square for nonprofits](https://goharness.com/blog-posts/square-alternatives-for-nonprofits) - **PayPal Giving Fund** (distinct from PayPal for Nonprofits) - 0% fees, but PayPal holds the donation and disburses to you on their schedule, and **you don't get the donor's contact info**. That makes it a dead end for building a recurring donor base. Great for a passive "donate via PayPal's charity directory" channel, bad as your primary. ## What I'd actually do Most nonprofits under ~$500K raised: **Zeffy or Givebutter for the donor-facing pages, Stripe nonprofit rate + PayPal as the processors underneath.** That's the lowest total cost with no meaningful feature sacrifice. Two things to insist on regardless of who you pick: **enable ACH/bank transfer** (1.9% vs. 2.9%, and the savings are large on major gifts), and **turn on "donor covers the fee"** - a majority of donors check it, which effectively zeroes out processing. Also confirm before signing that you can **export your donor list** in full; that's the thing that actually locks you in, not the fee. **Sources:** - [Stripe for Nonprofits: Fees, Setup, and Alternatives](https://www.zeffy.com/blog/stripe-for-nonprofits) - [Stripe for nonprofits: fees, discounts, and donation setup](https://checkoutpage.com/blog/stripe-for-nonprofits) - [PayPal vs Stripe: Which Payment Processor Is Best for Nonprofits](https://rallyup.com/learn/paypal-vs-stripe-which-payment-processor-is-best-for-nonprofits/) - [Zeffy Reviews: Pros, Cons, and Real User Experiences](https://donorbox.org/nonprofit-blog/zeffy-reviews) - [Stripe vs Givebutter fee comparison](https://paymentproviders.io/compare/stripe-vs-givebutter?focus=fees) - [Top alternatives to Donorbox in 2026](https://betterworld.org/blog/nonprofits/top-nonprofit-fundraising-software-alternatives-to-donorbox-in-2026/) - [Bloomerang vs Donorbox](https://toolradar.com/compare/bloomerang-vs-donorbox) - [Nonprofit fundraising platform cost 2026](https://projectcostestimator.com/blog/nonprofit-fundraising-platform-cost-2026) - [Best Square alternatives for nonprofits](https://goharness.com/blog-posts/square-alternatives-for-nonprofits) - [Nonprofit credit card processing](https://bloomerang.com/blog/nonprofit-credit-card-processing)
