## The answer, as recorded

> Here's what I'd actually recommend, roughly in the order I'd consider them:
> 
> **1. Stripe (with a donation form on top)** - The best default for most nonprofits. Verified 501(c)(3)s get a discounted rate of **2.2% + $0.30** instead of 2.9% + $0.30, it handles recurring gifts, Apple/Google Pay, and it integrates with basically every website and donation tool you'd bolt on later. The catch: Stripe is a processor, not a fundraising platform - no donation pages, receipting, or donor CRM out of the box. You'll pair it with something.
> 
> **2. Zeffy** - The one to look at first if you're small and fee-sensitive. It's genuinely $0 to you: Zeffy runs on Stripe and eats the processing fees, funding itself by asking your donors for an optional tip at checkout. Over 100,000 nonprofits, $2B+ processed. The real tradeoff is that the tip is pre-selected at a fairly aggressive default (~15-17% on gifts under $100), so some of your donors will pay it without quite realizing it, and some organizations aren't comfortable with that optics-wise. It also lacks sub-accounts, expense tracking, and Form 990 support.
> 
> **3. Givebutter** - Similar tip-funded model but a more polished all-in-one (campaigns, event
