Over-licensing
Paying for more than is used. Most common in organisations with high staff turnover.
How it shows up
- Subscriptions assigned to users who left and were never deprovisioned.
- Multiple users assigned identical premium SKUs when a shared plus a smaller tier would cover the actual usage.
- Duplicate coverage across overlapping programmes (for example, Microsoft 365 plus standalone Office bought separately).
- Perpetual licences forgotten after a project was cancelled, sitting unused but still valid.
