Entra ID SSO Integration Cost for a Line-of-Business App (2026)

The verdict in three sentences

When the CISO requires every new application to sign in through Microsoft Entra ID with MFA, an OpenID Connect integration is a short, well-defined project: 1,500 to 5,000 EUR and 2 to 4 weeks on the European market in 2026, including companies in London and Dublin. SCIM provisioning, an extra 2,000 to 6,000 EUR, is what actually eliminates orphaned accounts, because it disables access as soon as an employee leaves the directory. The Entra ID P1 licence, around 6 EUR per user per month, is often already included in your Microsoft 365 subscription.

What exactly you are buying

An SSO integration breaks down into independent components. Many quotes stop at the OpenID Connect sign-in, which covers authentication but not the account lifecycle.

The top of the range applies to older apps whose session handling must be reworked, or apps that also keep local accounts for contractors without a Microsoft account.

Licensing: what you already pay for

Before budgeting licences, check your Microsoft agreement. Conditional access, essential to enforce MFA by context, requires at least P1.

For a UK company pursuing Cyber Essentials, or an Irish one in scope of NIS2, SSO ticks several boxes at once: MFA on cloud services, centralised user access control, sign-in traceability and immediate revocation when someone leaves.

If the app is built by Kolonell, Entra ID SSO is priced within the custom app scope: 3,810 to 6,100 EUR (2,500,000 to 4,000,000 FCFA) for a simple app and 6,100 to 10,670 EUR (4,000,000 to 7,000,000 FCFA) for a medium app with SCIM and multi-tenant support.

Mini case study

Thomas, CISO of an 800-employee industrial mid-size company in Nantes (illustrative persona), must roll out a maintenance management app to 250 users. Without SSO, the service desk handles about 40 password reset requests a month at 15 minutes each, plus 15 joiners or leavers at 30 minutes of manual admin: 17.5 hours a month, or 875 EUR at 50 EUR per loaded hour. The OpenID Connect plus SCIM integration is quoted at 7,000 EUR; P1 licences are already included in Microsoft 365 E3. Payback: 7,000 divided by 875, i.e. 8 months, and zero orphaned accounts at the next audit.

FAQ

OpenID Connect or SAML?

For a modern web app, OpenID Connect is easier to maintain and better suited to mobile apps. SAML remains relevant for legacy tools, with integration costs often 10 to 20% higher.

Does the app handle MFA?

No, Entra ID enforces it before returning to the app. The app no longer stores passwords, which greatly reduces the attack surface.

What happens when an employee leaves?

With SCIM, their app account is usually disabled within 40 minutes of deactivation in Entra ID. Without SCIM, you need a manual process, the classic source of orphaned accounts.

Can we keep local accounts for contractors?

Yes, but it is better to invite them as external users in Entra ID. That avoids a second password policy and costs under 1,000 EUR to configure.

What timeline should we plan?

2 to 4 weeks, often including a week of waiting for the required admin rights on the Entra ID side.
