Build a app for invoicing

Job ID: 31715165

Budget: £250 – £750 GBP

Hi
Looking for a app to be built which can be loaded onto a tablet.
App is going to be on a tablet for drivers who will bill customers and then print onto a mobile printer.
I would want a copy of the invoice sent to head office in real time.
In the office once driver has completed his job we can check reports os sales products best selling and print various reports etc
