## The answer, as recorded

Asked on 2026-10-23 through Claude (Anthropic) with web search (model claude-opus-5).

> ## My actual recommendations, in order
> 
> **1. Zeffy - start here if you're small or mid-size.** Genuinely 0% platform and 0% processing fees; they survive on optional donor tips (~80% of donors opt in). Nothing else nets you 100% of a donation. Tradeoffs: narrower feature set than the big platforms, and your donors see a tip prompt at checkout, which some boards dislike. For a budget under a few million in annual giving, the math is hard to argue with.

> 
> **2. Stripe direct - best if you have any dev capacity or a custom site.** Apply for their nonprofit discount and you drop from 2.9% + $0.30 to **2.2% + $0.30**. Requirements: 501(c)(3) proof (EIN/IRS letter) and 80%+ of your Stripe volume from tax-deductible donations. Best-in-class API, recurring billing, and no monthly fee. This is the right foundation if you're building your own donation flow or your CRM plugs into Stripe.

> **3. PayPal at the nonprofit rate - add it, do
