    ABSTRACT

    The global community especially the technologically advanced world is striving to attain what has been the global information age. It is an age that is envisaged to go beyond the use of computers as a mere tool for fast information processing, rather they will also become medium for processing and transferring such information from one location to another at equal fast rate. As a result, it’s appalling that sales in developing country like Nigeria have not been able to benefit much from this revolutionized age of Information technology especially in the area of computerized Sales. A computerized sale management and control system is a computer program which takes the best out of a manual system and electronic cash registers features.

    An electronic point of sale gives you the ability to store client and supplier records, create quotations which can be later converted to invoices or cash sales, keep track and categorize your inventory in an easy way and generate reports at the click of a button! With today’s high performance computers and large storage devices one can easily run his/her business on an office computer (depending on the size of the business). However, SSADM as the research methodology was used which means structured system analysis and design methodology which is an internationally accepted software engineering model mainly used in most result oriented analysis. The new system was designed using hypertext preprocessor (PHP) programming language. While my sql was used for the data repository. This language was chosen because of its easy syntax and features for developing web based applications.

    CHAPTER ONE

    1.1 Introduction

    One of the great recent advances in the world of information technology is the rapid development of communication which has brought world into a global village, we can send mails electronically (e-mail), search for information (WWW), buy goods online (e-commerce), withdraw transfer money (e-banking), schooling online (e-learning), this has affected the society positive to a great extent, as result computerization of sales should not be exempt Application of technology in Sales has been adopted in developed countries for over two decades now, and this has been attributed to the desire of the governments of these countries to improve the efficiency of their goods and services, processes, accountability. Switching from a traditional cash register to a computerized sales system can be difficult - there are many factors to consider and some pitfalls to avoid. However the return on investment and benefits to your business can really make it worth your time and effort.

    In the most basic sense, a computerized sales system is a glorified cash register. The most basic sales system consists of a computer, a cash drawer, receipt printer, a monitor, and an input device such as a keyboard or scanner.

    • This method encourages fraud figures are easily manipulated and changed.

    1.4 Aim and Objectives of Study

    The aim of this project to design and implement a web based Point of Sale System for FPNO bookshop.This has the following objectives

    1. To provide full functional reports to management
    2. To be able to get a fast and accurate way of auditing records
    • Control those errors made by human beings due to shortcomings.
    1. And also make sure that problem accoutered in recording information is highly minimized.

    1.5 Significance Of Study
