Running a SaaS on Stripe? Here's every fee you'll pay — subscription billing, failed payments, chargeback costs, and the exact pricing model to optimise your margins.
Stripe Billing adds 0.5–0.8% on top of your processing fee. For a $49/month SaaS, that's $0.25–$0.39 per subscriber per month. At 500 subscribers, that's $125–$195/month extra. The question is: does Stripe Billing save you that in engineering time?
Stripe Billing includes: proration, trials, dunning (auto-retry failed payments), metered billing, upgrade/downgrade flows, coupon codes, and revenue recognition. If you'd need to build even one of these, Billing pays for itself.
| Plan Price | Processing Fee | Billing Add-on (0.5%) | Total Fee | You Keep |
|---|---|---|---|---|
| $9/month | $0.56 | $0.05 | $0.61 | $8.39 |
| $29/month | $1.14 | $0.15 | $1.29 | $27.71 |
| $49/month | $1.72 | $0.25 | $1.97 | $47.03 |
| $99/month | $3.17 | $0.50 | $3.67 | $95.33 |
| $299/month | $8.97 | $1.50 | $10.47 | $288.53 |
For SaaS businesses, involuntary churn from failed payments is often 1–3% of MRR per month. Stripe Billing's smart dunning retries failed payments at optimal times, sending automatic email reminders — typically recovering 50–70% of failed charges.
At $50k MRR with 2% involuntary churn, that's $1,000/month lost. If Stripe Billing recovers 60%, you get $600/month back — far exceeding the 0.5% Billing fee ($250/month). For SaaS with any meaningful MRR, Stripe Billing pays for itself through dunning alone.
Stripe offers custom pricing for high-volume businesses. For SaaS, the key thresholds are:
| Factor | Stripe | Paddle | Lemon Squeezy |
|---|---|---|---|
| Processing fee | ~3.4–3.7% | 5% + $0.50 | 5% + $0.50 |
| Tax handling | Manual (+0.5%) | ✅ Included | ✅ Included |
| Merchant of Record | ❌ You are MoR | ✅ Paddle is MoR | ✅ LS is MoR |
| Global tax compliance | Via Stripe Tax | ✅ Automatic | ✅ Automatic |
| Developer flexibility | ✅ Highest | Medium | Limited |
| Best for | Custom SaaS builds | Global indie SaaS | Simple digital products |
Stripe is cheaper on pure processing — but if you're selling globally and need automatic VAT/GST compliance, Paddle or Lemon Squeezy act as Merchant of Record, removing your tax burden entirely. At early stage, the 5% fee can be worth the compliance simplicity.
