BILLING-INFORMATION COOPERATIVE PROCESSING SYSTEM AND BILLING- INFORMATION COOPERATIVE PROCESSING METHOD

摘要

A billing information linked processing system with which billing subject information requested by a charging system and billing information calculated by a SaaS application can be compared, thereby eliminating billing losses. This billing information linked processing system is equipped with a charging system (1), and a SaaS application system (2) that provides a SaaS application to users and transmits user charge information to the charging system (1) on the basis of the type of charging for the SaaS application. The SaaS application system (2) obtains billing subject user information from the charging system for the charged month, and reports user charging information to the charging system on the basis of the billing subject user information. After the reporting to the charging system has been completed the SaaS application system confirms whether billing information which has not been registered in the charging system exists, and when unregistered information exists, information indicating that the unregistered information exists is reported to the operator of the SaaS application system.
