The verdict in three sentences
Adding SSO authentication (SAML or OIDC) to a B2B application costs in 2026 from 6,000 EUR (one protocol, one identity provider) to 18,000 EUR (multi-IdP, MFA, roles). SCIM provisioning (automatic account creation/deactivation) adds about 4,000 EUR. Budget 3 to 6 weeks; SSO has become a contractual requirement to sell to large accounts.
SAML, OIDC, SCIM: who does what
SSO vocabulary often scares people, but the logic is simple: SSO delegates authentication to the client's directory (Azure AD, Okta, Google Workspace). SAML and OIDC are two protocols for this; SCIM manages the account lifecycle.
| Building block | Role | 2026 cost (EUR) |
|---|---|---|
| OIDC SSO (1 IdP) | Modern delegated login | 6,000 - 9,000 |
| SAML SSO (1 IdP) | Classic enterprise standard | 7,000 - 10,000 |
| Multi-IdP (SAML + OIDC) | Several enterprise clients | 12,000 - 18,000 |
| SCIM provisioning | Auto create/deactivate | +3,500 - 4,500 |
| MFA / access policies | Second factor, policies | +2,000 - 4,000 |
Integration by identity provider
Cost also varies with the client's directory. Here are 2026 orders of magnitude by identity provider, protocol, and timeline.
| Identity provider | Recommended protocol | Timeline | Integration cost (EUR) |
|---|---|---|---|
| Azure AD / Entra ID | OIDC or SAML | 3-4 weeks | 6,000 - 10,000 |
| Okta | SAML or OIDC | 3-4 weeks | 6,500 - 10,500 |
| Google Workspace | OIDC | 3 weeks | 6,000 - 9,000 |
| Multiple directories | SAML + OIDC | 5-6 weeks | 12,000 - 18,000 |
Once the first IdP is integrated, adding a similar directory costs much less, because the SSO foundation is already in place.

Sophie, VP Product of an HR SaaS vendor in Nantes, must deliver SAML SSO to sign a contract with a large account of 2,500 employees. She picks SAML SSO + SCIM: the large account requires automatic account deactivation when an employee leaves. Budget 13,000 EUR (9,000 SAML + 4,000 SCIM), 5-week timeline.
The contract represents 60,000 EUR/year in subscription, impossible to sign without SSO. So SSO is not a cost but a revenue unlocker: 13,000 EUR one-off to secure 60,000 EUR/year recurring, i.e. payback within the first few months. Every future large account reuses the SAML foundation, making the next enterprise sales faster to deliver.
FAQ
SAML or OIDC: which to choose? OIDC is more modern and lightweight, ideal for new directories; SAML is still required by many legacy large accounts. Budgeting OIDC costs 6,000 to 9,000 EUR, SAML 7,000 to 10,000 EUR.
What is SCIM for? SCIM automatically creates, updates, and deactivates accounts from the client's directory, essential for security-conscious large accounts. Budget around 4,000 EUR on top of SSO.
Is MFA included? MFA is usually handled by the client's directory (Azure AD, Okta). Adding access policies on the application side costs 2,000 to 4,000 EUR depending on the rules.
Can several enterprise clients be supported? Yes, with a multi-IdP setup that handles several directories at once. The budget then lands between 12,000 and 18,000 EUR.
What timeline to deliver SSO? Budget 3 to 4 weeks for a single IdP and 5 to 6 weeks for multi-IdP with SCIM and access policies.
