This application can be very useful in reducing time at the billing section. In this project, we will strive to create a mobile app using which you can create invoice of the purchasing product without wasting time. User will select the product and scan the product’s barcode using mobile application and add it to the cart here user don’t have to type details & user will be able to directly see that item in the cart. It will manage the inventory as well as invoice will be generated automatically without any efforts. User will then just need to checkout at counter and pay the bill through online payment. This project will basically reduce manual work that happens at checkout counters for bill payment in shopping malls.
