ABSTRACT

This project work, is a computerization it computerized cash invoicing system of an organization. Different source of INVOICE whose scope and limitation are based on.

Sales and purchased invoice/ invoices inquiry on total balance and generation of report. But before we venture into that, attention should be drawn to the introductory part, the literati on review, and later the analysis of the existing system, and the design of the new system. Since there is constrain in time, this project will not go on exhaustive treatment of every expected module, module, rather will represent only sales and purchases invoice modules with two other operational modules subset of the broad menu. Nevertheless, there is provision for onward development of those expected modules and for other source of invoice and other operations to suit any organization. It is not the intention here to treat each module separately hence the entire project is menu driven to cover some of the facilities present. Lastly, it is an optimistic fact that after going through the text, one would be able to. 1. Know what is achieved have a clear knowledge of the project have a clear knowledge of the project be able to in prove it to suit other organization in reaction to other source and problems.

ORGANIZATION OF WORK

This project work “Design and implementation of Computerized cash invoicing system” is actually organized into two phases, the front page and the main write-ups. The front page comprises of title page, certification page, approval page, dedication page, acknowledgment, abstract, organization of work and table of content.

The second page consist of seven chapters, chapter one talks about the introduction to computer attendance scheme for patients information system for nurses, statement of problem, purpose of the study, aims and objectives, scope and limitation of the study.

Chapter two is the review of the relevant literatures.

Chapter three gives the relevant information about the existing system.

Chapter four and five deals with the design and implementation of the new system.

Chapter six is the documentation of the project work while chapter seven comprises of the recommendation, summary and conclusion.
