When an audit lands, it feels like one overwhelming demand. It is not. A Microsoft audit runs through a defined set of stages, and the leverage you have is very different at each one. The earlier you act, the more room you have to shape the number. This is the end to end map.
Stage one: the approach
Microsoft verifies licensing three ways, and the approach tells you which track you are on. A SAM engagement is voluntary and sales led, framed as a free optimization. A self verification is a contractual demand you cannot decline. A formal audit runs through a third party accounting firm under the MBSA audit clause. The wording of the first contact tells you which one you are facing, and your options narrow as you move from the voluntary track to the contractual one.
Stage two: scope and data request
Once an audit is live, the auditor defines scope and requests data. Some comes from scripts and inventory tools run across your estate, and a great deal comes from Microsoft own telemetry from Azure, Microsoft 365, and management tooling. This stage looks administrative but it sets the foundation for everything that follows. What you hand over, and how it is framed, shapes the draft.
Stage three: data collection and measurement
The auditor maps raw deployment data to licensable products and editions, then applies your entitlements. Each mapping decision moves money, because editions differ in price by multiples and auditors faced with ambiguity tend to map upward. Entitlements you cannot locate are entitlements the auditor will not credit.
Stage four: the draft Effective License Position
The auditor issues a draft Effective License Position, the reconciliation of deployment against entitlement. Many teams misread this as a verdict. It is an opening position built on assumptions, and it is where the defense begins, not where it ends.
| Stage | Leverage |
|---|---|
| The approach | Highest |
| Scope and data request | High |
| Measurement | Medium |
| Draft ELP and negotiation | Medium |
| Settlement | Lower |
Stage five: negotiation and settlement
The draft is contestable in full. Edition inflation, double counting, stale assets, virtualization assumptions, and unapplied downgrade rights all overstate exposure in predictable ways. Each correction that pulls the gap toward and below the 5 percent threshold changes the economics, because at or above 5 percent you reimburse verification costs and acquire licenses at 125 percent of price. Settlement is also where the audit can be separated from the wider commercial relationship so the renewal does not become a lever against you.
Your next step
The single most valuable move is to engage early, while you are still near the front of the sequence and your leverage is highest.
