I don't know the specifics in this case of course, but it's hardly unusual for companies to have some kind of internal billing between departments. This is, in fact, the best way I know of to get managers to realize and honestly consider the actual costs of their IT requirements. Ask anyone about backup and recovery policies, and you'll find out that ALL of their data needs to be backed up hourly, saved for 20 years, and MUST be restored within 30 minutes if a system crashes. Present them with monthly cost for that, and often they'll reconsider.
Charging per support ticket, and extra for rush jobs, would be another useful approach of the same kind.
