Master of Science / Department of Computing and Information Sciences / Mitchell L. Neilsen / Maintaining paper bills is always a tedious job and there is always a chance of missing the purchase orders or even the payment dates. But, using an online purchase order system makes it easier to enter and maintain the correct information. The main objective of this application is to keep track of all the purchase orders made by the faculty members or staff members of the department for their students or for their research work. All the purchase orders can be made just by one click by using the online purchase order system. The user needs to register with the website letting the admin know if he is an authorized user of the department. Once the admin gives the required permission the user can then create a new purchase order from the desired vendor registered with the department. He can also make the payment by providing the funding source through which the order will be paid. Then the orders are finalized and provided with an invoice in a pdf format which can also be printed. Additionally, there exists an Admin user who can manage/ view users and edit their PO’s according to the information provided by the user. The admin also has the permissions to add new vendors and manage them. This website is developed using the PHP Scripting Language which is one of the major technology used now-a-days to build various websites along with HTML, jQuery, CSS web technologies for a better design of the website. Major emphasis of this application is to build user interactive techniques for simplifying user needs and to provide specific products required by the user.
