The verdict in three sentences
Adding SSO (Single Sign-On) via SAML or OIDC to a business application costs EUR 4,000 to 12,000 in Berlin in 2026, depending on protocol, number of identity providers and whether you add automatic provisioning. The return comes from reduced helpdesk tickets (up to 30% of requests are password-related) and stronger security through centralized MFA. Plan for 3 to 6 weeks of implementation depending on the complexity of the client directory.
Why SSO became a B2B prerequisite
CISOs no longer want to manage yet another username/password pair. SSO lets their staff log into your application with their corporate credentials (Azure AD / Microsoft Entra ID, Google Workspace, Okta). This centralizes security: when an employee leaves, deactivating their central account immediately cuts access to all applications, including yours.
Two protocols dominate: SAML 2.0, the incumbent required by most large accounts, and OIDC (OpenID Connect), more modern and suited to web and mobile applications. Many projects implement both to cover all clients.
SSO vs local accounts: security, cost, support
| Criterion | Local accounts | SSO SAML/OIDC |
|---|---|---|
| Password security | Your responsibility | Delegated to the client company |
| MFA | To be built | Inherited from provider (included) |
| Deactivating a user | Manual, risk of oversight | Immediate via central directory |
| Password helpdesk tickets | High (20-30% of tickets) | Near zero |
| Enterprise requirement | Often rejected | Expected standard |
| Upfront cost | Low | EUR 4,000 - 12,000 |
| Per-user cost | Rising | Marginal |
SSO shifts the cost: you invest once at integration, but you remove the recurring cost of password management and unlock enterprise contracts.
What each block costs in 2026
| Block | Indicative 2026 cost (EUR) | Timeline |
|---|---|---|
| SSO OIDC (1 provider) | 4,000 - 6,500 | 2-3 weeks |
| SSO SAML 2.0 (multi-providers) | 6,000 - 10,000 | 3-5 weeks |
| Centralized MFA + policies | Included via provider | - |
| SCIM provisioning (auto create/deactivate) | 3,000 - 6,000 | 2-3 weeks |
| Role & group mapping (RBAC) | 2,000 - 4,500 | 1-2 weeks |
| Annual maintenance | 1,200 - 3,000/yr | - |
SCIM provisioning is often underestimated: it automates account creation and deactivation from the client directory, avoiding manual management and strengthening compliance. It is a genuine differentiator with enterprise clients.
Mini case study
Sophie is CISO of a logistics company in Berlin (240 employees). Her route-management business application had 240 local accounts, generating roughly 35 helpdesk tickets/month for password resets, about 7 hours of monthly support. She integrates SSO SAML with Azure AD (EUR 8,500) and SCIM provisioning (EUR 4,500), EUR 13,000 total. Result: password tickets drop to near zero, saving 84 support hours/year (about EUR 2,500), and automatic deactivation of departing accounts removes a major security risk. Security and support ROI in a little over 2 years, not counting the contracts unlocked.

FAQ
How much does SSO integration cost in 2026?
Between EUR 4,000 and 6,500 for an OIDC SSO with a single identity provider, and EUR 6,000 to 10,000 for a multi-provider SAML SSO. Add EUR 3,000 to 6,000 for SCIM provisioning.
SAML or OIDC: which should I choose?
OIDC is more modern and suited to web/mobile apps; SAML is still required by many large accounts. If you target enterprise clients, plan for SAML, or even both protocols.
Does SSO include MFA?
Yes, MFA is inherited from the identity provider (Azure AD, Google, Okta). You do not have to build it: this is a major security advantage of SSO.
What does SCIM provisioning add?
SCIM automates account creation and deactivation from the client directory. When an employee leaves, their access is cut immediately, without manual intervention. It is a strong argument for CISOs.
How long does an SSO project take?
Between 3 and 6 weeks depending on protocol and the complexity of the client directory. A simple OIDC SSO takes 2-3 weeks; adding SAML and SCIM extends it to 5-6 weeks.
