Microsoft Licensing Audit
A Microsoft licensing audit — done by us, on your behalf, before Microsoft does it to you — is the single most undervalued defensive engagement an enterprise can run. We build an independent license position baseline across every Microsoft SKU in your estate, validate qualifying user counts, reconcile invoices against deployed inventory, surface dual-use rights and BYOL exposures, and produce the same effective license position (ELP) report Microsoft's Software Asset Management (SAM) engagement would produce — except with the buyer holding the pen.
This is the proactive engagement — you audit your own estate before Microsoft does. If Microsoft has already opened an audit against you, that is the reactive scenario: see Microsoft audit defense — under audit now.
Microsoft Negotiations is an independent advisory firm. Not affiliated with Microsoft Corporation. We hold no Microsoft channel revenue, no rebate exposure, and no LSP partner relationship — 100% buyer-side.
Why a Microsoft licensing audit you commission is the only audit you should ever face
Microsoft's audit will start with an information request you can't refuse.
Microsoft contractually retains the right to verify your compliance. The audit request typically asks for hardware inventories, user lists, virtualization configurations, deployment scripts, and 36 months of administrative data. Most enterprises hand it over without an internal baseline. Microsoft then computes the gap, names the finding, and presents an invoice. By the time you respond, the framing is set — and the framing favors Microsoft.
Auditors don't share the same dual-use rights interpretation you do.
Microsoft Product Terms include dual-use rights, BYOL allowances, and disaster-recovery exceptions that are genuinely usable — but the auditor's default interpretation excludes most of them. Without an internal audit that has already documented your dual-use rights position, you can't defend it under audit pressure. The defense argument needs to exist on paper before the audit begins.
"Qualified User" is the lever Microsoft pulls every time.
M365 E3/E5, F1/F3 Frontline, and many subscription SKUs are licensed per Qualified User. The contractual definition is broad. Microsoft's audit interpretation tends to be broader — counting contractors, service accounts, delegated mailboxes, and read-only users. An internal audit documents your operational definition with evidence (HR roster, AD attribute, MFA enrollment) so the Qualified User count is yours, not theirs.
Audit findings compound — the longer you wait, the worse the math.
Microsoft audits are retrospective. A shortfall identified today is computed against historical pricing — including SA renewals, true-up uplifts, and back-billing for 12–24 months. The longer an unaudited gap sits in your estate, the larger the historical recovery. The economic case for an internal audit is roughly $400K per $4M of annual Microsoft spend per year of estate drift.
Our six-phase Microsoft licensing audit methodology
Estate Discovery
We discover every Microsoft instance in the estate: M365 tenants, Azure subscriptions, on-premises SQL/Windows/Exchange/SharePoint servers, EA-licensed Power Platform environments, D365 deployments, Copilot tenant licenses, and CSP partner deployments. Discovery uses both Microsoft admin centers and on-premises inventory tools (SCCM, Tanium, or equivalent).
Entitlement Baseline
We build the entitlement baseline from your EA, MPSA, CSP, and SCE contracts. Every SKU is decomposed into base license, SA, online services component, virtualization rights, dual-use rights, and step-up rights. The baseline is the ceiling against which deployed inventory is measured.
Deployed-Inventory Reconciliation
We reconcile deployed inventory against entitlement: M365 assigned licenses, Azure subscription usage, on-premises server counts (cores, processors, OSEs), and SQL Server edition deployment. Every variance is logged: under-deployment (recoverable cost), over-deployment (compliance exposure), and configuration mismatches (audit risk).
Qualifying User & Dual-Use Documentation
We document the Qualified User count with evidence: HR roster, AD attributes, MFA enrollment, and email-account allocation. Dual-use rights are documented separately with use-case evidence (home-use, secondary device, BYOL). The documentation is the defense if Microsoft challenges either count.
Audit-Risk Quantification
We quantify audit risk: probable shortfall in dollars, range of likely findings, defensibility score per finding, and historical recovery exposure. The quantification answers the CFO question: "What's the biggest check Microsoft could plausibly hand us?" — and what's the smallest.
Remediation & Audit-Defense Brief
You receive a remediation plan (true-up at next anniversary, license demotion, architecture change, contract amendment) and an audit-defense brief that's pre-loaded for the moment Microsoft initiates verification. The brief is the difference between a $400K and a $40K audit outcome.
Major 2026 changes that affect this engagement
Four 2026 commercial events have together reset Microsoft EA economics: the EA Volume Tier collapse, the Unified Support 8–12% amplifier, the M365 E7 frontier bundle, and the July 2026 list-price uplift. Every engagement we run is sized against these four levers — the engagement cost is recovered first by pricing them correctly.
Level A–D pricing flattens; mid-market loses its discount base
A 6–12% structural lift before any SKU changes. Defended through MACC commitment engineering and co-term consolidation.
02 · Unified Support 8–12% AmplifierEvery EA dollar flows through as 8–12 cents of Unified Support
Now structural — modeled as a deal-level KPI. Cap negotiation or third-party Tier 3 migration is the defense.
03 · M365 E7 Frontier SuiteThe $99/user E7 bundle is the new top-of-stack upsell
E7 only outperforms components above ~65% Copilot adoption. Most enterprises should run a tiered E5/E7 population.
04 · July 2026 Lock-In WindowM365 list-price increases on 1 July 2026 — co-term before that date
5–9% recovery against the post-July uplift for any EA signed before the window.

Insurance Holding Group
16,000 employees | Pre-audit defense | Insurance & Financial Services
Pre-audit defense engagement. Internal audit identified $1.6M of probable Microsoft shortfall findings and documented defense for $1.2M of them — qualifying user definition tightening, dual-use rights documentation, and SQL Server core-count corrections. When Microsoft initiated SAM engagement six months later, the audit closed at $410K — versus the $1.6M starting exposure.
Manufacturing Group
9,800 employees | First-time internal audit | Manufacturing & Industrial
First internal audit since 2018. Surfaced $680K of historical SQL Server core-shortfall exposure and 220 dormant M365 E3 licenses. Remediated through a controlled true-up at next anniversary (not under audit pressure, so at standard EA pricing, not at audit-finding penalty pricing).
