The answer, as recorded
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 events and P2P and want it all in one place. **3. Donorbox** - The workhorse for clean, high-converting recurring forms: suggested amounts, one-click monthly upgrade, good embeds. Free Standard plan with a platform fee on top of processing; the Pro plan ($150/mo) lowers that fee, so it flips to worth-it at volume. Verify the current platform % on their pricing page before you commit - published comparisons disagree on the exact rate. **4. CharityEngine (SustainerIQ)** - The one to pick if recurring giving *is* your program and the dollars are meaningful. It's built specifically around the problem that kills sustainer revenue: involuntary churn. Automatic credit card updater via the card networks, intelligent failed-payment recovery rather than blind retries, pre-failure alerts. They claim ~98% sustainer retention and 90%+ recurring collection. Overkill for a $5k/mo program; the obvious choice at $100k+/mo, where recovering 20-30% of failed payments dwarfs any platform fee. **5. DonorPerfect or Bloomerang** - If you want recurring billing inside a real CRM rather than bolted on. DonorPerfect is the deeper fundraising database; Bloomerang is better for mid-sized teams without technical staff, with retention analytics as the selling point (its dunning is simpler - retries at 3, 7, and 15 days, then pauses the gift). ## For true subscription billing (memberships, dues, tiered access) **Stripe Billing** - Start here. Apply for the nonprofit discount: 2.2% + $0.30 instead of 2.9% + $0.30. Two important catches - memberships, event tickets, Amex, and international cards are **excluded** from the discounted rate, and Stripe Billing adds its own usage fee on top of processing. So the discount may not apply to the exact use case you're asking about. **Chargebee** - Only if you have genuinely complex billing (metered usage, mid-cycle proration, multi-currency, dunning workflows) that Stripe Billing alone can't express. There's no publicized nonprofit pricing; you'd have to negotiate directly. ## My actual advice Don't buy "subscription billing software." Pick the fundraising platform, and let it handle the billing. The only reason to reach for Stripe Billing or Chargebee directly is if you're selling memberships or program subscriptions that aren't tax-deductible donations - at which point you're a normal subscription business and the nonprofit-specific tools fit badly. Two things to weigh above price: whether the platform has a **card updater** (expired cards, not donor intent, cause most sustainer churn), and what its **failed-payment retry logic** does. A tool that silently pauses gifts after three tries will quietly cost you far more than a 3% platform fee.
