Yes, you can! If you wish to send one invoice to your client with all your worked hours from multiple projects, it is now possible with the Projects to invoice feature. This feature lets you create an invoice with any number of projects you want for the same client, and then you can choose to include worked hours and expenses for any selected period of time.
To charge a client for worked hours related to a project, simply select the Projects to invoice action from the Projects menu.
On the following screen, set a specific date range to create an invoice for worked hours and expenses included in that period only.
Locate the client you wish to bill and click the Invoice client option from the Action menu:
When you are done, click Create invoice. You will then be able to complete the invoice created with
your project hours and expenses.
