Inventory Control System

                 records the supply and purchase of goods & items, which are issued, returned, purchased or used.

                 Billing System
                 When we visit a shop for buying something, the billing software records and prints the memo of the
                 transaction we make.

                 The person at the counter has to just enter the name of the product with its quantity, and the billing
                 is automatically done. If there is a gadget like bar code reader then the operator at the counter has to
                 just scan the bar code which lies in the packing and enter the quantity of the product and the billing is
                 automatically done.
