Microsoft / SPLA Audit Process
The Microsoft SPLA audit process, mapped for hosters.
How a SPLA audit runs for service providers in 2026. The reporting trail auditors follow, the SPUR rules that decide the claim, and the buyer side defense.
How a SPLA audit runs for service providers in 2026. The reporting trail auditors follow, the SPUR rules that decide the claim, and the buyer side defense.
A Microsoft SPLA audit checks your monthly usage reports against deployed product. For hosters the defense starts long before the letter, in the reporting trail itself.
A Services Provider License Agreement lets a hoster license Microsoft products to deliver services to third parties. You report and pay monthly for what you deploy, with no upfront ownership.
That monthly model is the whole audit story. The review measures what you reported against what you ran.
Hosting providers, managed service providers, and software vendors who run Microsoft product for customers. The SPLA program sets the eligibility and reporting rules.
You report deployed product to your reseller every month and pay on that declaration. Accuracy of the monthly report is what an audit ultimately tests.
A SPLA audit reconstructs your usage history from reports and deployment. Each phase gives the hoster a checkpoint to scope and verify.
The Microsoft SPLA audit phases
| Phase | What happens | Your move |
|---|---|---|
| Notice | Audit firm named and scoped | Confirm the review period |
| Report pull | Monthly declarations gathered | Match reports to invoices |
| Deployment scan | Running product inventoried | Reconcile against reports |
| Draft claim | Gap and back period issued | Challenge SPUR mapping |
| Settlement | Number and terms agreed | Negotiate the back period |
An independent audit firm appointed under your SPLA, reporting to the Microsoft licensing desk. The Microsoft Product Terms and the SPUR define the rights they measure you against.
Auditors check whether your monthly reports match what you ran, and whether each product was licensed under the right SPUR rule. A disciplined software asset management practice keeps that trail clean. The gaps cluster in reporting and infrastructure.
The monthly report is the primary evidence. Auditors compare it against deployment scans and invoices, so any month that under declares becomes a finding with a back period attached.
Shared infrastructure raises hard questions about who consumed what. Confirm that internal use was licensed separately and that SQL Server cores on shared hosts were reported correctly.
The standard advice is to report conservatively, keep reports light, and sort out the detail if an audit ever comes. We disagree. In most of the 25 to 35 SPLA audits we defended in 2024 and 2025, light reporting was exactly what produced the back period and the penalty exposure. The buyer side move is the opposite: report accurately every month, keep your SPUR mapping current, and treat the monthly declaration as the audit defense it actually is. A clean reporting trail caps the claim before it starts. Hosters who reported well cut the final number by a median near 30 percent. Underreporting does not save money. It defers and compounds it.

For a hoster, the SPLA audit is decided months before the letter arrives. The monthly report you file is either your strongest evidence or the source of the claim.
The Services Provider Use Rights document defines how each product may be licensed for hosting. A claim turns on whether your reporting matched the current SPUR, not last year's.
Microsoft updates the use rights regularly, and a product licensed under a retired rule becomes a finding. Map each reported product to its current use right before an audit forces the question.
A Microsoft SPLA audit checks a service provider's monthly usage reports against deployed product. It reconstructs what you ran each month, compares it to what you declared, and issues a claim for any gap with a back period.
Any hoster, managed service provider, or software vendor that holds a Services Provider License Agreement. The audit clause in the SPLA gives Microsoft the right to verify your monthly reporting.
Auditors start with your monthly usage reports. They match each declaration against deployment scans and invoices, so the months where reported usage falls short of deployed product become the core of any claim.
The Services Provider Use Rights document defines how each Microsoft product may be licensed for hosting. A SPLA claim turns on whether your reporting matched the current SPUR, since products mapped to retired rules become findings.
The back period is set by your SPLA and the available reporting history, commonly two to three years. A clean monthly reporting trail is what limits how far the auditor can reach.
Gaps between reported and deployed usage, and stale SPUR mappings. In the reviews we defend these two issues account for the largest share of every disputed claim, well ahead of any other cause.
Yes. The SPLA claim is an opening position. You can negotiate the number, the SKUs applied, and the back period, especially when your monthly reports support a lower figure than the auditor assumed.
Hosters defend best by reporting accurately every month and keeping SPUR mappings current. Clean reports cap the claim before it starts, which is why the strongest defense is built long before any audit letter arrives.
Microsoft renewal moves, the EA framework, the M365 SKU framework, the Copilot framework, and the buyer side moves across the full Microsoft estate.
Used across more than five hundred enterprise engagements. Independent. Buyer side. Built for procurement and IT asset leaders facing a Microsoft review.
With SPLA, the audit is won or lost in the monthly report. The hosters who report accurately every month walk into the review with their defense already written.
