Why London

London is a Microsoft audit priority.

Banks, insurers, asset managers, magic circle law firms, and FTSE headquarters cluster here, and every one of them runs large Microsoft estates. High seat counts, complex data center footprints, and frequent mergers make this a target rich region for verification activity.

Dense enterprise estates

The City and Canary Wharf carry deep Microsoft 365, Windows Server, and SQL Server deployments. Scale is exactly what draws a formal audit under the MBSA audit clause.

Hosters and managed providers

The UK cloud and managed service market reports under SPLA every month. A 36 month lookback turns small reporting gaps into large back fee demands at the price file rate.

Merger driven drift

Acquisitions move licenses, tenants, and users faster than records keep up. That drift is where an auditor finds unlicensed use and pushes you past the 5 percent line.

What we do

What we do when the audit letter lands in London.

We take the same disciplined position whether the contact is a sales led SAM engagement, a contractual self verification you cannot decline, or a formal audit run through a third party accounting firm.

  • We run your own internal assessment first, before Microsoft counts, so you control the data and the narrative.
  • We challenge the auditor methodology and the Effective License Position line by line, because their count is not the final word.
  • We keep unlicensed use below the 5 percent threshold that triggers reimbursement of verification costs and license purchase at 125 percent of price.
  • For hosters we rebuild SPLA reporting discipline: monthly SAL reports on time, sealed daily authentication counts, customer mapping, and documented multi tenant boundaries.
  • We negotiate the negotiable. Back fees at the price file rate are fixed, but the penalty uplift of 25 to 125 percent is where we win room.
Two tracks

End customer and hoster defense, kept distinct.

The mechanics differ. We never blur them. A London enterprise faces a license position audit. A UK hoster faces a monthly compliance audit across a rolling lookback.

End customer track

Microsoft verifies licensing three ways. SAM tool output is not audit defense because Microsoft uses its own counting methodology and its own data from Azure, Microsoft 365, and management tooling. Declining the initial SAM review and running your own internal assessment first is a recognized defensive move. Read more in our Effective License Position explainer.

Hoster track

SPLA is monthly pay as you consume. Compliance is verified for every monthly cycle across a 36 month lookback, conducted by a Big Four firm under the MBSA audit clause. Reporting discipline is the structural defense. See the SPLA Reporting Discipline Playbook.
