basically my problem is an android app for field sales reps, with logon data for sales reps, crud for customers, crud for sales order, products, discounts with a backend in php and mysql for admin tasks, like create new sales reps to use mobile for order taking, crud for customers, crud for products, crud for sales order
Field Sales Reps solution.
Backend with PHP & MySQL, basically for admin task on system, CRUD for sales reps data, customers, products and sales orders, backend should have one login screen and user should be able to manage the sales reps which will be using the android application.
Android application, basically an order taking, login screen based on backend sales reps data, crud for customers in application, products and discounts for consulting and creating sales order with customer informations, products data and discounts, all of this synchronized with backend, would be nice if app works offline, with a local database and synchronization with backend.
One app that could be used as example is inSitu Sales, the sales option, with customer, items and sales order.
