Licences get bought in a hurry, assigned to people who later leave, layered with add-ons that duplicate what the base plan already includes, and renewed automatically on a date nobody has in their diary. This guide sets out how to reconcile what you are billed for against what is assigned and what is genuinely used, where the waste consistently hides, the six-step process for running the audit, how to read the admin centre reports without misclassifying mobile-only and quarterly users, how to right-size plans without silently removing security controls, what the exercise typically saves a UK business, why renewal timing decides when you actually bank it, and the mistakes that turn a cost exercise into a security incident.
