Within Teamwork Projects, you can add expenses to your invoices.
Go to the Billing area of your project and select the Unbilled Expenses subsection.
There are filtering options available at the top of the expenses area.
To add a new expense choose Add Expense to the far right of the page.
You will then have the option to add information for the expense.
Once you have added the expense, you can move it to an invoice if you wish.
To do this, select the box to the left of the expense name and choose Move Items.
You can then choose the invoice you want to move it to from the dropdown menu.
You can also move one or multiple expenses to an invoice using drag and drop.
Note: Once an invoice has been completed, any attached expenses will be marked as billed.
