The main aims and objectives of the system are: • To design a web based invoicing system to replace some extent of human role in cases of unavailability of job. • To provide quick retrieval of customer’s invoice records on site or case of loss of original invoice. Also, the purpose of this software is to model a computerized invoice system to enable proper invoice generating for customers and control these records.

1. DESIGN AND IMPLEMENTATION OF AN ELECTRONIC INVOICING SYSTEM
The internet, without doubt, has played an important role in digitalizing business
processes across companies and organizations of all sizes. It has introduced multiple new
channels through which businesses can interact with their customers [1]. A report by
Gartner, an Information Technology (IT) research institution, reveals that 70% of all
customer interactions will move towards digital, more interactive settings and would be
experienced on demand through mediums such as web, mobile and social media
platforms by 2017. The generation of today understands technology more than ever and
require services delivered as quickly as possible, whenever and wherever they desire [2].
To achieve all these, companies do not have to make huge capital investments by
purchasing and maintaining software licenses for applications like Enterprise Resource
Planning (ERP), Inventory Management System (IMS) and Customer Relationship
Management (CRM) systems and installing them on individual hardware on the business
premises [3]. They can instead contain costs, deploy solutions quicker and minimize risk
by using this Electronic Invoicing System hosted by a third party and delivered over the
internet , Its purpose is to bring an inexpensive and easy solution to the business
operation needs of customers especially the Small and Medium-sized Enterprises
(SMEs). The system allows businesses to create and send computerized invoices to their
customers [4].
o STATEMENT OF PROBLEM
During the analysis and data collectionof this project, it was discovered that there existed
a manual form of collecting and storing customers’ invoices in other for them to be
attended to, and for future purpose [5].
That is to say that the process of daily task and activities are done manually which is

2. quite unfortunate; manual procedural execution produced delays in writing down all the
customer bought, at some instances the business owner can’t keep a proper record of the
goods and services sold out in a particular day, week or Month, which reduces result in
businesses.
Manual invoicing record keeping has resulted in many setbacks to the expected standard.
The setback encountered includes:
 Time wastage in writing down everything bought by some customers.
 Partial or total loss of invoice by both business and customers.
 Under recording of invoice analysis.
 Inefficiency of some members of staff due to laziness in searching of the invoice.
As a result of these problems, the manual system of invoice record information storage,
input and retrieval is very clumsy: inefficient and unbelievable.
o PURPOSE OF THE STUDY
To develop a computerized Electronic Invoicing software to carryout tedious work and
activities performed by human beings, in which they end up misplacing and discarding
some important files and costumers records. But if this (computerized Invoicing
software) is implemented and installed it will render remedy to this case.
o AIMS AND OBJECTIVES
The main aims and objectives of the system are:
 To design a web based invoicing system to replace some extent of human role in
cases of unavailability of job.
 To provide quick retrieval of customer’s invoice records on site or case of loss of
original invoice.
Also, the purpose of this software is to model a computerized invoice system to enable
proper invoice generating for customers and control this records.

3. o SCOPE
The researcher is concerned with an electronic invoice system. It cover all the operations
of companies and businesses in issuing receipts to customers which is the case study. It
deals with the digitalizing business processes of issuing of receipts to customers for the
services rendered or bought.
o ORGANIZATION OF STUDY
Chapter Two reviews the related literature under the following sub-headings: Invoicing
System, the review of the site, electronic invoicing system, Implementation of the new
mode of receipts, etc.
Chapter Three handles the System Methodology Analysis and Design as follows:
Introduction, the User Interface, Hardware and Software requirements, user
documentation, system backup, system maintenance, etc.
Chapter four is concerned with the system implementation and programming.
Chapter Five comprises of summary, conclusion and recommendation.
o LIMITATION OF THE STUDY
There are some limitations or constraints confronting this study, they are as follows
 TIME: I have a very little time to carry out this research this was the fact that I
combine the research work with my academic studies. You can agree with me that
time constraints is one of the limitations I experience while carry out this research
work.
 FINANCE: however, finance is another constraint I experience while carry out
this research. The lack of funds to carry out this research slow down the research
work. Despite the limitations every effort was geared towards accomplishing this
project.
