You can raise an Invoice for your completed Job from the 'Invoices' tab

From the dashboard, select 'Jobs' 

Select your Job from the list and from the Job Details screen select 'Invoices' from the tabs at the top of the screen.

For Franchisee Partners, Invoices are automatically created when data has been uploaded from the mobile device and the status of the jobs is at [Data Received].

Whilst the invocie is at [Draft] status, you can delete using the trash can icon and re-generate the invoice using the button [Add Invoice]
