Records needed for this question
Registered service locations, fee schedules and location-change logs.
How to investigate
Compare billable location units with active registrations rather than employee headcount.
An illustrative review decision
An emergency-location service can be billed separately from the voice line. Match the location record and applicable service terms rather than assuming the charge duplicates ordinary connectivity or address maintenance.
What can lead to the wrong conclusion?
A remote employee and a registered emergency location are not always equivalent billing units.
The result to retain
A location-fee mapping for carrier clarification.
