Errors and savings come from one of two areas. Rate and Tariff or Physical Inventory. Rate and tariff means that customer is not accurately charged for service according to the tariff or contract. Or subtler the application of the tariff itself as often configuration will determine when specific charges are applicable. The second area is Physical Inventory, which means that customer cannot be charged for lines that are either not at the location or not in service. TIG has developed a proprietary method for identifying these opportunities quickly and taking corrective action. All errors and refunds are pursued regardless of the size. Once all errors corrected, cost savings recommendations are made and those approved by the customer are implemented. Typical customer has hundreds of open issue at any one time.
