In order to create a new invoice you need to go to Accounting → Invoices→ Add invoice. You can add items manually to the invoice by inserting new rows or by clicking on the Add outstanding time/costs and select from the dropdown:
- Add from Timesheet – creates an invoice based on tracked time
- Add from Expenses – adds expenses to the invoice, but make sure they have the same currency as the invoices.
- Add from Projects – creates an invoice based on flat rate projects
- Add from Tasks – creates an invoice based on flat rate tasks
NOTE: If you select Add from Timesheet, there's the option to attach a time report to the invoice to offer more details about what you've been working on.
You can also create an invoice by going to Projects → Select a project → Overview → Click on Invoice Unbilled AR.
