DESIGN AN IMPLEMENTATION OF A COMPUTERIZED TELEPHONE BILLING SYSTEM (A CASE STUDY OF NITEL ENUGU)

CHAPTER ONE

INTRODUCTION

Billing System is System that tracks customer usage of services, and calculates the impact on a customer’s account, based on the price of the services A computer-based billing system is necessary for handling and preparing of accurate bills for customers. The new system will facilitate the prompt preparation of bills, easy retrieval of information, security to vital information and resource sharing among the billing department. The previous billing system lacked the flexibility to quickly update services and provide customers with an acceptable level of detailed information. It is also programmer intensive to maintain,” said Miguel Echeverria, manager, information and technology. In addition to the new billing system, customer bills have been redesigned to better serve customers. The new design is much more user friendly. Accounts with multiple water services will now have an account summary page followed by a detail sheet for each service. All accounts will receive a new account number that will have a nine-digit customer number followed by a sevendigit premise number.

The billing system is presently handling manually by the marketing department. The marketing department took over the function of revenue billing from the traffic department in the 80’s. Their main function is to raise customer’s bills of all statutory charges against users for the services rendered to them. The role at which the bills are prepared with the increasing number of customer is insignificant. There are procedural ways in which these bills are being prepared. A staff has to raise as many bills as the number of the customer increases. Hence, a thorough investigation and analysis of the manual billing method enables me to gain understanding on the true nature of their problems and design a computerized billing system that would bring solutions to the problem inherent
