The Retail Store Management System is a system designed for managing i.e. for ordering, arranging and selling goods.

The Retailer checks for the availability of goods in the store. If the stock of goods is less, then retailer places order for goods. While ordering the goods, goods area received at store, the retailer then arranges them by product or by price, and then retailer makes payment. If the stock of goods is available then he will arrange goods for selling.

The retailer then sells the goods directly to the customer. The customer buys the items from retailer. The retailer prepares bill for goods purchased by the customer, he receives amount by credit or by cash from customer. The supplier supplies the goods to the store in the system. The overall system is used to manage the goods in the store.
