The question asked, verbatim: best payment processing for nonprofits

Brands named, in the order the engine gave

1. Stripe recommended
   Stripe - The default for most nonprofits.
2. third-party recommended
   Its biggest advantage isn't the fee - it's that donors stay on your branded page instead of being bounced to a third-party site, which measurably reduces drop-off.
3. Pay recommended
   It integrates with nearly every CMS and donation tool, and handles recurring gifts, Apple Pay, and Google Pay cleanly.
4. Amex recommended
   Caveat: the discount doesn't cover Amex (3.5%) or international cards.
5. Zeffy recommended
   Zeffy - If your top priority is keeping 100% of every dollar, this is the answer.
6. Givebutter recommended
   Givebutter - The one I'd pick over Zeffy if you need more than a donate button.
7. PayPal recommended
   PayPal - Worth adding alongside Stripe rather than instead of it, purely because some donors trust the PayPal button.
8. PayPal Giving Fund recommended
   Separately, PayPal Giving Fund offers genuinely zero-fee processing for verified 501(c)(3)s.
9. Square recommended
   Square - Specifically for in-person fundraising: galas, community events, merch tables.
10. Bloomerang recommended
    Bloomerang / Kindful - If you want processing and donor management in one system rather than stitching tools together.
11. Bloomerang / Kindful recommended
    Bloomerang / Kindful - If you want processing and donor management in one system rather than stitching tools together.

The answer, as recorded

# Best payment processing for nonprofits Here's what I'd actually recommend, roughly in the order I'd consider them: **1. Stripe** - The default for most nonprofits. Verified 501(c)(3)s can get a discounted rate of **2.2% + $0.30** (vs. the standard 2.9% + $0.30) by emailing [email protected]. Its biggest advantage isn't the fee - it's that donors stay on *your* branded page instead of being bounced to a third-party site, which measurably reduces drop-off. It integrates with nearly every CMS and donation tool, and handles recurring gifts, Apple Pay, and Google Pay cleanly. Caveat: the discount doesn't cover Amex (3.5%) or international cards. **2. Zeffy** - If your top priority is keeping 100% of every dollar, this is the answer. Truly $0: no platform fee, no per-transaction fee, no monthly fee. It's funded by an optional tip donors are prompted to add at checkout. The trade-off is that the tip prompt sits in front of your donors, and the feature set is narrower than the big platforms. Best for small-to-mid orgs with straightforward needs. **3. Givebutter** - The one I'd pick over Zeffy if you need more than a donate button. Free when donor tips are on; 3% platform fee if you turn tips off. You get peer-to-peer fundraising, event ticketing, auctions, text-to-give, and a built-in CRM - a genuinely broad toolkit for the price. **4. PayPal** - Worth adding *alongside* Stripe rather than instead of it, purely because some donors trust the PayPal button. Nonprofit rate is **1.99% + $0.49**. Note the math: that high fixed fee makes it worse than Stripe on small gifts (~5.3% vs ~4.2% on a $15 donation) and better on large ones. Separately, **PayPal Giving Fund** offers genuinely zero-fee processing for verified 501(c)(3)s. **5. Square** - Specifically for in-person fundraising: galas, community events, merch tables. Fast onboarding, good hardware, and it's the easiest option when you need to take cards at a physical event. **6. Bloomerang / Kindful** - If you want processing and donor management in one system rather than stitching tools together. Bloomerang runs 2.4% + $0.30 for nonprofits. You pay a bit more per transaction for the integrated donor data and campaign tooling. **My short version:** Stripe for your website + Square for events covers most organizations well. If budget is genuinely tight, go Zeffy (pure $0) or Givebutter (more features, still effectively free). Add a PayPal option if your donor base skews older or you already have a PayPal following.
