The question asked, verbatim: best subscription billing software for nonprofits

Brands named, in the order the engine gave

1. Donorbox recommended
   Donorbox - my default recommendation.
2. Zapier mentioned
   ~2.95% platform fee on the free tier (plus processing), with add-ons like Zapier/API around $17/mo.
3. Zeffy mentioned
   Zeffy - genuinely $0 to the organization: no platform fee, no processing fee, funded by an optional donor tip at checkout.
4. Givebutter mentioned
   Givebutter - similar tip-funded model (0% with tips on, ~3% if you turn them off), but a broader free suite: fundraising pages, peer-to-peer, events, and a built-in CRM.
5. Neon CRM mentioned
   Neon CRM - the one I'd name when memberships with dues, tiers, and renewals are the core model (associations, museums, clubs).
6. Bloomerang mentioned
   Bloomerang - small-to-mid nonprofits that want recurring gifts plus a real donor-retention CRM in one place, from about $25/mo.
7. Stripe mentioned
   Stripe Billing - if you're already on Stripe and your plan catalog is simple.
8. Stripe Billing mentioned
   Stripe Billing - if you're already on Stripe and your plan catalog is simple.
9. Chargebee mentioned
   Chargebee - when pricing gets complicated (tiers, proration, multi-currency, entitlements) and you don't have engineers to spare.
10. Recurly mentioned
    I'd skip Recurly here - it starts around $249/mo plus 0.9%, which only pencils out at high volume.

The answer, as recorded

Most "subscription billing for nonprofits" questions are really one of two things: recurring **donations/memberships**, or true **subscription billing** for earned revenue (course fees, SaaS-style programs, paid memberships with entitlements). Here's who I'd actually name, in order. ## For recurring giving and memberships (most nonprofits) **1. Donorbox** - my default recommendation. The deepest recurring-donation management of the low-cost tools: donor self-service portals to update cards, failed-payment recovery, upgrade asks, and good form conversion. ~2.95% platform fee on the free tier (plus processing), with add-ons like Zapier/API around $17/mo. Best if monthly giving is a real program you manage, not a checkbox. **2. Zeffy** - genuinely $0 to the organization: no platform fee, no processing fee, funded by an optional donor tip at checkout. Unbeatable on cost for small US/Canada 501(c)(3)s. Tradeoff: you're pushing the ask onto your donors, and the recurring/CRM depth is thinner than Donorbox. If you're under a few hundred thousand in online revenue, the savings usually win. **3. Givebutter** - similar tip-funded model (0% with tips on, ~3% if you turn them off), but a broader free suite: fundraising pages, peer-to-peer, events, and a built-in CRM. Pick this over Zeffy if you run campaigns and events, not just a donate button. Givebutter Plus is ~$29/mo for the extra layer. **4. Neon CRM** - the one I'd name when *memberships* with dues, tiers, and renewals are the core model (associations, museums, clubs). Auto-billing, renewal workflows, and membership status live inside the CRM instead of being bolted on. **5. Bloomerang** - small-to-mid nonprofits that want recurring gifts plus a real donor-retention CRM in one place, from about $25/mo. Strongest on retention reporting; billing is adequate rather than sophisticated. ## For actual subscription billing (earned revenue, paid programs) **6. Stripe Billing** - if you're already on Stripe and your plan catalog is simple. ~0.7% of billing volume, self-serve customer portal, best-in-class API. Note Stripe's separate nonprofit processing discount is applied for through Stripe directly, not automatic. **7. Chargebee** - when pricing gets complicated (tiers, proration, multi-currency, entitlements) and you don't have engineers to spare. Strong dunning/revenue recovery out of the box; pay-as-you-go starts around 0.80% of billing value. I'd skip **Recurly** here - it starts around $249/mo plus 0.9%, which only pencils out at high volume. **Practical note:** whatever you pick, confirm it supports ACH/bank debit for recurring gifts. Card expirations and declines are the single largest source of monthly-donor churn, and ACH churns at a fraction of the rate. Also verify current fee structures directly with each vendor - Givebutter and Zeffy in particular have changed their tip/fee models more than once.
