Stripe Billing + Stripe Tax — Default stack for AI SaaS with usage-based pricing
AI SaaS almost universally needs usage-based billing. Stripe Billing has the best primitives for metered pricing, and Stripe Tax keeps tax compliance inside one vendor.
Pricing summary
Pay-as-you-go: 0.7% of billing volume. Or from €500/month (pay monthly, up to €80k volume/mo, 1-year contract, 0.67% beyond). Plus standard Stripe payment processing (1.5%+€0.25 EU cards).
Estimated monthly cost
| Stage | Stripe Billing | Total |
|---|---|---|
| $0 (starting) | Free | Free |
| $5k MTR | ~$35 | ~$35 |
| $25k MTR | ~$175 | ~$175 |
| $100k MTR | ~$700 | ~$700 |
Estimates exclude payment processing fees and App Store / Google Play platform cuts. MTR = monthly tracked revenue.
