Customize open-source Jbilling software for store application

POS Create a robust and responsive point-of-sale interface that pulls from existing Jbilling page data (Customer, Create Order, Create Invoice), and create new features that are not native to Jbilling, such as a cash register open button, standard receipt generator, and bar code read/generation. The database schema will also have to be changed slightly to include order due dates, order locations (rack number), and order status (in-transit, in process, etc.). Customer Page Create a customer sign-up page that will be linked to Jbilling. Customer data will need to be validated by an admin.
