Enterprise SSO for a Web App (2026)

The verdict in three sentences

Adding SSO (Single Sign-On) to a SaaS costs 5,000 to 18,000 EUR in 2026 depending on protocols and provisioning. It's not just another technical feature but a condition of sale to enterprise accounts: without SSO, the client's IT department blocks. SCIM and fine-grained role management turn a SaaS into an "enterprise-ready" product.

SSO integration cost in 2026

The budget depends on supported protocols (SAML 2.0, OIDC), the number of identity providers (Azure AD/Entra, Okta, Google), and whether you add automatic user provisioning (SCIM).

Standard protocols (SAML, OIDC) are unavoidable: enterprise accounts use Azure AD/Entra ID, Okta or equivalent, and require one of these two protocols.

SAML, OIDC, SCIM: who does what

These three building blocks meet distinct needs. Confusing them leads to vague quotes and disappointed client expectations.

SCIM is the real differentiator: it automatically creates, updates and disables accounts from the client company's directory. It's a strong argument for IT departments managing hundreds of users.

SSO as a sales lever

SSO often makes the difference between a signed contract and a lost deal. Many enterprise buyers reserve SSO for their "Enterprise" plans and bill it as an extra, raising the average deal size. Above all, without SSO or SCIM, the client's IT department refuses deployment on security and access-governance grounds. Adding SSO means unlocking an entire customer segment.

Mini case study

Julie, CEO of a 20-person HR SaaS vendor in Lyon, loses a 45,000 EUR/yr deal because the prospect (2,000 employees) requires SSO and automatic provisioning. She orders a SAML + OIDC + SCIM integration with role mapping: 15,000 EUR, delivered in 10 weeks. Result: the deal signs, and SSO becomes a standard argument that unblocks two more enterprise prospects that year. At 45,000 EUR per contract, the integration is paid back with the first client.

FAQ

SAML or OIDC: which to implement first?

SAML 2.0 remains the most requested by legacy enterprise accounts. OIDC is more modern and suited to API-first architectures. Ideally support both to cover all prospects.

What does SCIM concretely bring?

SCIM automatically syncs accounts from the client's directory: creation on hire, disabling on departure. It removes manual management and reassures IT departments on access governance, especially beyond 100 users.

How long to add SSO?

3 to 5 weeks for a simple SSO, 9 to 14 weeks with SCIM and role management. The availability of the client-side IdP (for testing) is often the limiting factor.

Does SSO justify a higher pricing tier?

Yes, it's a common practice: reserving SSO for the "Enterprise" plan raises the average deal and frames the integration and support effort. Many vendors bill it as an extra.

Can SSO be added to an existing app?

Yes, SSO integrates into an app already in production without a full rewrite. You add a compatible authentication layer and map roles. Plan a test phase with the first client's IdP.
