## The answer, as recorded

> Here's what I'd actually recommend, roughly in the order I'd bring them up:

The recurring donation form is genuinely the best part of the product: multi-step checkout, donor-managed subscriptions (donors can update cards/amounts themselves), and failed-payment retry. Embeds anywhere, sets up in an afternoon. Costs a platform fee on top of Stripe/PayPal processing.
> 
> **2. Zeffy** - Recommend this first if budget is the binding constraint. 0% platform fee *and* 0% on recurring gifts; they cover processing costs and monetize via an optional donor tip at checkout. Over three years, a $25/month sustainer costs you literally nothing versus ~$80+ elsewhere. Tradeoff: the tip prompt is prominent, and the CRM side is thinner than paid tools.
