Verdict
Stripe Billing is the default subscription layer for SaaS teams already on Stripe Payments, with subscription management, smart retries, hosted invoicing, customer portals, and Stripe Tax integration on top of the payment rail. The pricing is 0.5% on recurring revenue at Standard or 0.8% at Scale, layered on top of standard Stripe payment fees. The cost flip happens when MRR crosses roughly $500K-$1M ARR and the percentage starts to compound, when a team selling globally would rather outsource sales-tax compliance to a Merchant-of-Record, when usage-based real-time metering becomes core to pricing (AI inference, infra), when an OSS maintainer needs creator-friendly fees, or when the finance organization needs proper ASC 606 revenue recognition.
Where alternatives win
Paddle operates as Merchant of Record at 5% plus 50c per transaction, with global VAT, sales tax, fraud, and chargebacks handled on your behalf; nets cheaper than Stripe Billing plus separate tax compliance tools for international B2B SaaS.
Lago is Apache 2.0 open source with a usage-based billing engine built for real-time event metering, adopted by Mistral, Groq, and Together.ai for AI inference billing where Stripe Billing's subscription-first model does not fit.
Chargebee Launch is free up to $250K ARR (the most generous free tier in the segment), with multi-gateway support that avoids Stripe-lock-in and add-on management plus workflows on Rise at $599 monthly.
Recurly Core at $199 monthly is the mid-market subscription pick with smart dunning that typically recovers 30-40% of failed renewals and ASC 606 revenue recognition on the Professional tier.
Polar is GitHub-native at 4% plus 40c per transaction with Merchant-of-Record tax handling, the right call for OSS maintainers monetizing GitHub sponsorships, paid actions, or premium releases.
Stripe Billing built on top of Stripe's payment infrastructure adds subscription management, smart retries, hosted invoicing, customer portals, and Stripe Tax integration. For developer-led teams already using Stripe Payments, adding Billing wins for that shape and the extra 0.5% fee is fair pricing for the breadth of features.
Where Stripe Billing is shape-mismatched: a SaaS selling globally that wants to outsource sales tax compliance entirely (Paddle's Merchant-of-Record model), a team building usage-based pricing where real-time event metering matters (Lago or Orb), an OSS maintainer monetizing GitHub work (Polar), or an enterprise needing revenue recognition depth (Recurly or Chargebee). Each pick below leads for one of those shapes.
Pick by your business shape. Global SaaS wanting MoR tax handling equals Paddle. Usage-based real-time billing equals Lago or Orb. OSS-friendly creator monetization equals Polar. Enterprise revenue recognition equals Recurly or Chargebee. Mid-market subscription depth equals Chargebee.
