The answer, as recorded

"Subscription billing" for a nonprofit usually means one of two things - monthly/recurring *donations*, or real *subscription billing* for memberships and dues. Here's what I'd actually recommend for each. ## For recurring donations (most nonprofits) **1. Givebutter** - My default recommendation for small-to-mid orgs. Genuinely free: 0% platform fee when donor tipping is on (3% if you turn tips off), with fundraising, a CRM, and engagement tools bundled. Recurring plans retry 3 times at 48-hour intervals, then pause until the donor updates their card. Main catch: phone support is gated behind the paid Plus tier (~$29/mo). **2. Donorbox** - Best pick once your monthly giving program is a real program. The deepest recurring-giving and donor-management features of the cheap tier, embeddable forms, multi-currency. It retries a failed charge twice more at 2-day intervals with a 10-day donor self-fix window, and covers card account-updater fees for expired cards - which matters a lot for churn on monthly donors. Costs ~2.95% platform fee on the free tier, plus add-ons (Zapier/API ~$17/mo). **3. Zeffy** - The choice if fees are the whole decision. 100% free - no platform fee *and* no card fee, funded entirely by optional donor tips, covering donations, ticketing, auctions, memberships, and newsletters. The tradeoff is less depth and less control than Donorbox, and you're asking your donors to subsidize the platform at checkout. **4. Bloomerang** - Pick this if you want a serious donor CRM first and giving tools second, especially for retention-focused programs. One important gotcha: if you use Bloomerang Payments as your processor, failed recurring payments are *not* retried at all. On other processors it retries at 3, 7, and 15 days. **5. GiveWP or Charitable** - Only if your site is WordPress and you want donations native to it rather than an embedded third-party form. ## For actual subscription/dues billing (memberships, program fees) **6. Stripe Billing** - The honest answer for most orgs with real subscription needs. Note the nonprofit discount (2.2% + $0.30 vs 2.9% + $0.30) applies to *donations only* - not memberships, tickets, or event revenue, which is exactly the thing you'd be billing. You also need >80% of volume to be tax-deductible donations to qualify. **7. Join It** - Purpose-built for membership dues. Stripe Billing and Chargebee are designed around SaaS anniversary-based billing and handle fixed renewal dates (e.g., "everyone renews January 1") poorly; Join It is built for that pattern. **8. Chargebee** - Overkill for most nonprofits, but the right call if you have complex plans, proration, invoicing, and dunning on top of Stripe or PayPal. **Short version:** Givebutter if you want free and simple, Donorbox if monthly giving is a core program, Zeffy if zero fees wins, Bloomerang if you need the CRM - and Join It rather than Stripe Billing if it's membership dues on fixed renewal dates.
