The verdict in three sentences
Integrating a business app with Microsoft Entra ID SSO via OpenID Connect costs EUR 2,000 to 6,000 (about USD 2,200 to 6,500) and ships in 2 to 4 weeks. Adding SCIM provisioning (about EUR 3,000) creates and disables accounts automatically, closing the most common gap: the former employee who keeps access. With Entra ID P1 licenses at about EUR 6 per user per month for conditional access, a mid-size company sees on average 20% fewer password tickets.
Integration options and their cost
The security lead of a mid-size company wants one rule: no internal app without SSO. Budget depends on the protocol, the state of the existing code and role management.
| Option | Use | Indicative 2026 budget | Timeline |
|---|---|---|---|
| Basic OpenID Connect | SSO login, roles managed in the app | EUR 2,000 to 3,500 | 1 to 2 weeks |
| OpenID Connect + Entra ID roles | Entra groups mapped to business roles | EUR 3,500 to 6,000 | 2 to 3 weeks |
| SAML 2.0 (legacy app) | Compatibility with existing code | EUR 3,000 to 7,000 | 2 to 4 weeks |
| SCIM provisioning | Automatic create, update, disable | EUR 3,000 | 1 to 2 weeks |
| Multi-directory (subsidiaries, B2B partners) | Several Entra tenants, external guests | EUR 5,000 to 10,000 | 3 to 5 weeks |
| Audit and logging | Sign-in logs exported to the SIEM | EUR 1,500 to 3,000 | 1 week |
For a recent app, the most common scenario (OIDC + roles + SCIM) lands between EUR 6,500 and 9,000.
Entra ID licenses and recurring costs
Basic SSO is included in Microsoft 365 subscriptions. Advanced security features require a higher license.
| License | Key features | Indicative 2026 price |
|---|---|---|
| Entra ID Free (included in M365) | SSO, default MFA | EUR 0 |
| Entra ID P1 | Conditional access, dynamic groups, advanced SCIM | about EUR 6 per user per month |
| Entra ID P2 | Identity protection, access reviews, PIM | about EUR 9 per user per month |
| Microsoft 365 E3 | P1 included | about EUR 36 per user per month |
| Microsoft 365 E5 | P2 included | about EUR 57 per user per month |
| Integration maintenance | Secret rotation, library updates | EUR 500 to 1,500 a year |
Check your Microsoft 365 contract first: many mid-size companies already pay for P1 through E3 without using it on their business apps.
Rollout method
Week 1: register the app in Entra ID, define roles and groups. Week 2: development and testing on a staging environment. Weeks 3 and 4: SCIM, conditional access (managed device, location), gradual cutover and removal of local passwords. Keep a break-glass account outside SSO, protected and logged, for Microsoft incidents.

Sophie, CISO of a 900-employee manufacturing company, runs 12 business apps, 5 of them without SSO. Her help desk handles 300 password tickets a month at EUR 18 per ticket, or EUR 5,400 a month. She integrates the 5 apps with OIDC and SCIM at EUR 7,500 each, or EUR 37,500. Result: 20% fewer tickets, saving EUR 1,080 a month, and above all accounts disabled within 15 minutes of a departure instead of 9 days on average. The direct savings pay back the project in 35 months, and the avoided risk justifies the decision long before that.
FAQ
How much does integrating an app with Entra ID SSO cost?
Budget EUR 2,000 to 6,000 for OpenID Connect, plus EUR 3,000 for SCIM provisioning. A legacy SAML app can reach EUR 7,000.
Do we need an Entra ID P1 license?
Not for basic SSO, which is included in Microsoft 365. P1, at about EUR 6 per user per month, is needed for conditional access and dynamic groups.
How long does the project take?
From 2 to 4 weeks per app depending on the code and the need for SCIM. Several apps can be handled in parallel on a shared foundation.
What happens if Microsoft is down?
A break-glass account outside SSO, with hardware MFA and logging, keeps you in control. Entra ID outages remain rare, with a 99.99% availability commitment.
Does SSO help with NIS2 compliance?
Yes, it centralizes strong authentication and access traceability required for many mid-size companies. Combined with SCIM, it also documents access revocation.
