Plastic Trade System is developed for the purpose of computerizing the maintenance of raw materials, product, customer, supplier, employee and other information, which replaces all the records that are handled manually. There are many records such as customer information, supplier information, employee information, purchase details, sales details, product details, raw material details etc… Since it involves a lot of work so it is very difficult task for the user to maintain all these manually. This program is written in a small and easy way to access each form by clicking on the command buttons on main screen. It provides the flexibility to work on the system very easily. The user does not need to remember the entire menu system. It is a user’s friendly program.

This project will manage the sales and purchase activities which are done in the company, maintaining the stock details and the records. The details regarding attendance, salary and purchase details are also maintained. The user will consume less time in calculation and the sales activity will be completed within minutes whereas manual system will make the user to write it down which is a long procedure and it also consumes a lot of time. This system reduces paper work and the user can spend more time on monitoring the company. This product aims to be user friendly and easy to use.
