As the name suggests, the E-billing and Invoicing System is an application that is designed to computerize the billing part and in-voicing matters of the shops. The existing system involves a lot of man power. All the records are maintained through the files and registers. There is no security provided for the details that are stored in files and registers. So this application will help in computerizing the work related to the billing in shops. This will help in getting the clients details just in one mouse click. This will be one of the interesting applications that one can work on and implement in real time.
