DESIGN AN IMPLEMENTATION OF A COMPUTERIZED PREPAID BILLING INFORMATION SYSTEM

ABSTRACT
With the advance in technology more in particular in the field of computer related organization, a lot of things are now automated. As a matter of fact, Information technology has a vital role in the design and implementation of electric billing system. Almost all the big organization are developing their billing system because of the extraordinary benefit resulting from information technology. Information technology has enabled electric billing system to work successfully. To ease the operation of PHCN co-operation, researcher took up this study by critically understanding the work, procedure involved, analysis of the various steps and at the same time detecting problem in the present system and designing a new system that has solution to the problem of the existing system. The new design is computerized and is subject to modification at any given time. It also have this interaction feature and accurate in it's output. This program is designed using visual basic and access.
