ABSTRACT

 

In the course of the project research, the design and implementation of a Computerized Invoicing System was Studies. The rapid increase in information technology have substituted the primitive system of invoicing. This advancement have helped in invoice updating since certain mistakes like sales calculation, alterations and irregular writings of clerks can now be avoided.

Personal Computers (PC) can now be used to call-up Charts, table and figures of various kinds to obtains an instant reading on the sales. This work reveals the millennium mechanism through which information could be stored modified and recalled instantly and accurately. If unavoidably includes the development of sales processing and information in business transactions.

Analytical method involved invoice input analysis of computerized invoicing system used in Bubbles Plaza.

1.0     INTRODUCTION

A computer system is a grouping of functional devices which have electronic ; electrical, and mechanical features respectively and have the capacity to accept and store data for reference purpose through a recall or retrieval mechanism to present a feed back to its users and have the capacity for communications and resource sharing.

The progress in information revolution resulted in the use of computer in information management which have shown high efficiency rate, specifically in sales services. Sales can be defined as he exchange of goods and / or services for a price which can be money or other goods / service on the other hand, invoicing is an expression or word that can be substituted for sales, once a sale is made; details of the transaction are taken and documented in form of invoice. These Operations of sales can be done through writing and description of the transaction; this is called involving operation. Computerized invoicing system tries to reduce the problem of manual handling of sales. Such problems include: Inaccuracies in calculations, fine wastage and inefficiency in service delivery.

As regards to this topic, computer systems are used to record sales and issue invoice to customers which have put off the burden of manual handling of sales.

In Bubbles Plaza, the use of electronic digital communication through which multi-media is transmitted have tremendously increased speed, accuracy and total efficiency. Also have increasingly integrated an internal scope and impact in sale management.
