Device management apparatus, non-transitory computer-readable storage medium, and device management method that can update a table based on data received from a device

摘要

Provided is a device management apparatus that performs accurate billing processing. A billing-management unit, based on billing-counter information having cumulative data received from a device, updates registered information in a billing-management table that includes updated data that is updated based on the cumulative data; and a system-control unit, based on comparison results of comparing the cumulative data and the updated data, controls updating of registered information in the billing-management table by the billing-information-management unit. By comparing cumulative data received from a MFP and updated data registered in a billing-management table, a system-control unit can determine whether or not a problem has occurred in cumulative data received from a MFP. As a result, even when for some reason a problem occurs in cumulative data received from a MFP, updated data in which a problem has not occurred can be managed.
