IT due diligence software licensing adds the entitlement measurement an architecture and security review leaves out, so the largest hidden software cost is priced before close.
IT due diligence software licensing is the part of the IT diligence workstream that standard reviews treat lightly and publishers treat seriously. An IT diligence team will assess architecture, security, and technical debt, but the licence position underneath those systems is where a target's largest hidden cost usually sits. We add the licensing measurement that turns an IT review into a complete one.
IT due diligence software licensing is different from the rest of the workstream because it measures entitlement, not function. A system can be well architected, secure, and modern, and still be deployed far beyond what its licences permit. That gap does not show up in an architecture review or a security assessment. It shows up when a publisher audits after a change of ownership, which is a common trigger. We reconcile deployed usage against entitlement for the publishers that matter and quantify the exposure so it joins the rest of the IT diligence findings as a priced item.
Inherited software licensing exposure is usually latent and unquantified in standard due diligence, and it lands as a publisher audit after close. As of June 2026, public reporting shows SAP pursued AB InBev for a figure in the region of 600 million dollars, and the Diageo Great Britain Ltd v SAP UK Ltd judgment, [2017] EWHC 189 (TCC), confirmed indirect access can require licensing. An IT diligence review that skips licensing leaves the largest software variable unpriced.
| IT diligence area | Typical focus | Licensing exposure |
|---|---|---|
| Infrastructure | Architecture and resilience | Processor based licence breaches |
| Applications | Fit and technical debt | Named user and edition overage |
| Cloud and SaaS | Consumption and tooling | Autorenewal and duplicate seats |
| Security | Controls and posture | Tooling licensed below deployment |
| Change of control | Continuity of service | Consent and reprice triggers |
A standard IT due diligence review is built around capability and risk. It asks whether the architecture will scale, whether the security posture is sound, and whether technical debt will slow the combined business. Those are the right questions, but none of them measures entitlement. A platform can pass every architectural test and still be deployed far beyond what its licences permit, because the deployment that creates exposure is invisible to a review that looks at how systems are built rather than how they are licensed. The result is that the single largest hidden cost in many estates sits outside the scope of the workstream meant to surface it.
IT due diligence software licensing fixes that by treating entitlement as its own measurement. We take the deployment data the IT review already gathers, such as server inventories, virtualisation maps, and user directories, and we reconcile it against the licence entitlement for each material publisher. Virtualisation is a frequent culprit, because spreading a licensed workload across a cluster can multiply the licensable footprint without anyone changing a contract. The output joins the IT diligence report as a quantified line, so the deal team weighs the licence liability against the other findings and prices it with the same discipline.
The licence finding belongs in the IT diligence report as a quantified line, not a footnote. We deliver a range by publisher, the renewal and audit events that will move it, and the change of control terms that depend on deal structure. That lets the deal team weigh the software liability against the other IT findings and price it into the offer. Because we are independent and paid only by the acquirer, the figure is built to survive the investment committee. We provide commercial and licensing advisory, not legal advice, and recommend your own counsel for the interpretation of any contract term.
