## The answer, as recorded

Asked on 2026-10-01 through Claude (Anthropic) with web search (model claude-opus-5).

> Quick note on framing: "subscription billing for nonprofits" splits into two different products, and the right answer depends on which you mean - **recurring donations** (sustainer/monthly giving) or **true subscription billing** (memberships, dues, tiered access with proration, invoicing). I'll cover both, leading with recurring giving since that's the usual need.
> 
> ## For recurring donations (monthly giving)
> 
> **1. Zeffy** - My default recommendation for small orgs and anyone fee-sensitive. Genuinely 0% platform *and* 0% processing fees; they're funded by optional donor tips added at checkout. You keep 100% of every recurring gift. The tradeoff is real: your donors see a tip prompt, and the CRM/reporting is thinner than paid tools. If your monthly program is under ~$10k/mo, the fee savings almost certainly outweigh the feature gap.
> 
> **2. Givebutter** - Best free-tier feature set. Core product is free; with tips enabled the "Givebutter Guarantee" means no platform or processing fees, but with tips *off* you pay ~3% platform. Strong campaign pages, peer-to-peer, and events alongside recurring. Givebutter Plus from $29/mo scales with contact count. Pick this over Zeffy if you run even
