The philosophy of the activity-based chargeback system is that SSG will be responsible for managing the unit cost of the individual voice services and the customer will be responsible for managing the consumption of services. The consumption of services will now be monitored through detailed reports generated by the chargeback system. In contrast to the simplified chargeback system, users will now be charged for the services actually consumed. Unfortunately, this new philosophy cannot be implemented for free. Many of the savings (both hard and soft) that accrued from billing simplification would be eliminated. For SSG, the cost to develop and implement the detailed billing system is estimated to be $700,000. Ongoing support of the developed systems, including maintenance of charging accuracy is estimated to be $1,200,000 per year. Similarly, the cost savings enjoyed by BCAG and ISDS from billing simplification will be eliminated when detailed billing is resumed.
