The billing system project is developed using VB.net and ms-access. A billing system is a software application which helps to generate invoices for a customer and their billing details. Earlier data was stored in excel sheets which were difficult to maintain for a large number of customers. It also had redundancy so this automated system solve those needs by a software which can keep track of the customer transaction and store each product details. Using this application we can manage customer details, product details and billing details in a database.So it becomes easy to access these records from anywhere. It also generates reports for billing and invoice details.
