How WorkOS bills you
The pricing model is per connection / mau-based. Enterprise-readiness APIs (SSO, SCIM Directory Sync, Audit Logs, AuthKit) with a famously generous free tier and clean per-connection pricing for B2B SaaS. Best suited to: enterprise sso & scim for b2b.
What to watch for on the bill
- Per-connection SSO/Directory Sync pricing ($125/connection/mo) scales with customer count, not revenue, the most common complaint
- A single SSO customer can cost more than a SaaS vendor's own lowest-tier plan, blocking SSO-on-all-tiers strategies
- Audit log and SIEM streaming add-ons stack additional monthly costs
- Costs can become unpredictable as enterprise connections accumulate
