The SAML/SSO Taxation Model
For B2B SaaS, offering SAML/SSO (Single Sign-On) integration is the gateway to the enterprise. However, SaaS vendors historically weaponize SSO, moving it strictly into their highest-tier "Enterprise" pricing plans (the "SSO Wall of Shame").
While enforcing an "SSO Tax" drives revenue upgrades, it inherently compromises the baseline security of small-to-mid accounts by forcing them to rely on weak passwords and scattered credentials.
Economically, you must balance the immediate MRR gain of paywalling SSO against the long-term enterprise value risk of a credential stuffing attack on a non-SSO client that ultimately breaches your platform.
The MRR strictly generated by customers forced to upgrade solely to unlock SAML.
The reduced legal liability when a client uses SSO (IdP owns the authentication risk).
Evaluate the long-term impact of offering SSO as a standard feature across all paid tiers.
Action Items
Why do most B2B SaaS companies place SAML/SSO exclusively in their most expensive pricing tiers?
Lifecycle Management (Join/Mover/Leaver)
Identity economics isn't just about logging in; it's about offboarding. When an employee is terminated, how long do they retain access to your AWS console, CRM, or source code?
Manual offboarding has a 100% failure rate over a long enough timeline. Forgotten SaaS accounts (Shadow IT) result in "orphan accounts" which are prime targets for takeover, as nobody is monitoring them.
The ROI of automated SCIM (System for Cross-domain Identity Management) provisioning is realized through avoiding catastrophic, post-termination insider threats.
Active accounts tied to departed employees.
Protocol to automatically create/destroy accounts via the central IdP.
Conduct a manual access audit on your top 3 most critical SaaS applications.
