Following the success of this engagement, the client commissioned SAMexpert to perform a proactive SPLA compliance assessment across its wider infrastructure. This internal review validated a strong licensing posture, identified targeted improvements, and mitigated potential risks valued at seven figures under worst-case audit assumptions.

Together, these projects delivered significant cost avoidance, strengthened governance, and enhanced audit readiness.


Client Profile

  • Industry: Cloud & IT Services (UK and international operations)

  • Operations: Global cloud and managed services infrastructure

  • Engagements: Microsoft SPLA Audit Defence, Internal SPLA Risk Assessment


The Scope

Audit Defence. Faced with an official Microsoft SPLA audit, the client required a pre-submission risk assessment, validation of data and contractual scope, challenge of auditor assumptions and Effective License Position (ELP), and development of a strategic negotiation plan.

Internal SPLA Risk Assessment. Following the audit defence, the client commissioned SAMexpert to conduct a "mock audit" of its broader SPLA infrastructure, quantify both best- and worst-case compliance positions, identify cost-avoidance and risk-reduction opportunities, and provide recommendations to strengthen governance and audit readiness.


The SAMexpert Approach

Phase 1: Baseline Risk Assessment (Audit)

SAMexpert performed a comprehensive risk assessment before data submission:

  • Reviewed contracts, SPLA terms, and reporting history

  • Analysed system deployments and data integrity

  • Modelled potential exposure scenarios, both best- and worst-case

Phase 2: Data Validation and Auditor Engagement

  • Ensured all data packets were validated, cleansed, and defensible before submission

  • Identified anomalies, including decommissioned environments and misaligned onboarding timelines

  • Produced explanatory documentation to pre-empt auditor challenges

Phase 3: ELP Challenge

When the auditor issued their draft ELP, SAMexpert conducted a deep-dive analysis to identify misinterpretations, introduced overlooked surpluses and exclusions to offset shortfalls, coordinated multiple iterations of rebuttals and supporting evidence, and ensured the final ELP accurately reflected the client's actual licensing position.

Phase 4: Negotiation Strategy

A three-tiered negotiation strategy was developed. Disruption: challenging audit assumptions and highlighting Microsoft enablement failures. Alignment: positioning the client as a partner open to future licensing evolution. Timing: leveraging fiscal deadlines and audit fatigue for concessions.

Phase 5: Internal SPLA Risk Assessment (Group Infrastructure)

  • Conducted a mock SPLA audit replicating Microsoft's methodology

  • Reviewed every month between January 2019 and November 2023

  • Identified low-level compliance gaps with best-case deficit <£7K

  • Highlighted potential worst-case risks >£1.2M if auditors assumed different technical interpretations

  • Provided practical recommendations to reduce risk and improve data evidence collection
