Building a Defensible ELP Before Microsoft Does

PUBLISHED MARCH 14, 2026 · UPDATED MAY 6, 2026

The auditor will build your Effective License Position. The stronger move is to build your own first, from the data Microsoft can actually see.

When a Microsoft audit reaches its end, the auditor produces an Effective License Position, the reconciliation of what you deployed against what you own. The mistake most organizations make is to meet that number for the first time when the auditor presents it. The stronger move is to build your own defensible ELP before Microsoft does. This top of funnel article explains how.

What an ELP is and why it decides the outcome

The Effective License Position compares deployment to entitlement across your estate and shows where you are covered and where you are short. It is the document that drives the financial result. The contract clause means that if unlicensed use is 5 percent or more of total use, you reimburse verification costs and acquire licenses at 125 percent of price. Whoever builds the ELP first frames that conversation.

Why a SAM tool position is not the same thing

A SAM tool can give you a useful inventory, but it is not audit defense. Microsoft uses its own counting methodology and its own data from Azure, Microsoft 365, and management tooling, and that calculation governs. A clean SAM tool ELP can still differ from Microsoft's number. A defensible ELP anticipates how Microsoft will count, not just how your tool counts.

How to build a defensible ELP

10,000 licenses5005 percentCosts reimbursed, 125 percent pricing
10,000 licenses9009 percentCosts reimbursed, 125 percent pricing

These figures are indicative, but they show why finding and closing gaps before an audit can change which side of the line you land on.

Build it first, defend from control

An organization that walks into an audit with its own defensible ELP responds to the auditor with evidence rather than surprise. It can challenge the method, correct the count, and keep unlicensed use below the threshold that triggers the heaviest terms. Building the ELP first is the difference between negotiating your position and receiving it.
