The first 30 days after an SAP audit notification are critical. Actions taken — and mistakes made — in this window have a disproportionate impact on the final outcome. If you have received an SAP audit letter, contact us before responding to SAP or providing any documentation.
A global manufacturing group with operations across 14 countries received notification of an SAP software audit covering their global ERP estate. SAP's initial communication framed the audit as a routine compliance review — standard language designed to reduce the urgency of the client's response and lower their defences before the measurement process began.
The client's IT leadership initially engaged directly with SAP's audit team, providing system access and preliminary usage data before retaining specialist counsel. This is a common and costly mistake. Within eight weeks of the audit notification, SAP's measurement team had identified what it characterised as a $4.8M licence gap, covering indirect access, modified users, and engine licensing under SAP's S/4HANA transition framework.
The client's position was further complicated by three factors:
By the time the client retained us, SAP had already issued a formal preliminary findings letter and was pressing for settlement within 45 days. The situation was serious — but far from settled.
Our first action was to formally halt the audit process. We issued a response to SAP's audit team challenging the methodology, timeline, and preliminary findings, and invoked the client's contractual rights to an independent technical assessment. This reset the process to a neutral starting point and bought critical time — removing the artificial 45-day settlement pressure that SAP had imposed.
We conducted our own independent technical measurement of the client's SAP estate using the same tools SAP uses — but applying the contractual licence definitions rather than SAP's preferred expansive interpretations. The independent measurement identified four categories of error in SAP's preliminary findings: incorrect indirect access attribution (21 third-party systems counted as direct users), legacy system double-counting (two decommissioned systems incorrectly included), incorrect engine licence classification for three manufacturing modules, and a methodology error in SAP's USMM data extraction that had been misapplied to a cloud-hosted system.
We prepared a comprehensive technical defence document that addressed each element of SAP's preliminary findings with specific contractual evidence: licence agreement definitions, deployment records, decommissioning documentation, and technical architecture diagrams demonstrating the correct classification of indirect access scenarios. This 140-page document established the evidentiary basis for our challenge to SAP's $4.8M claim.
Armed with a technically robust counter-position, we engaged SAP's audit resolution team — not the account team — for commercial negotiation. Our former SAP licensing director led the discussion, navigating both the technical disputes and the commercial framing. We explicitly separated the audit settlement from the S/4HANA migration conversation, refusing SAP's attempt to bundle them and exposing the inappropriate pressure tactic to SAP's own management chain.
Settlement was reached at $200K — covering one genuinely unresolved indirect access scenario that our technical assessment confirmed was within SAP's contractual rights to include. Beyond the settlement, we negotiated an audit lock-out provision (no further SAP audit for 36 months), a formal indirect access clarification letter that protected the client's current architecture, and an S/4HANA migration commercial framework that was significantly more favourable than SAP's standard proposal.
The engagement delivered a 96% reduction in SAP's initial claim, avoiding $4.6M in licence liability. The 36-month audit lock-out provision and the S/4HANA migration commercial framework were additionally valued by the client's CFO at a further $2.1M in risk-adjusted value over the following three years.
The client's General Counsel noted that "the quality of the technical defence document — and the team's knowledge of SAP's own methodology — fundamentally changed SAP's position. They knew immediately they were dealing with people who had sat on the other side of that table."
"SAP came in with a $4.8M claim and seemed very confident. Within four months, Atonement Licensing had dismantled their methodology, challenged their findings on every significant point, and settled for $200K. The knowledge they brought — from the inside — was decisive."General Counsel — Global Manufacturing Group
