When you track time in Teamleader (see this article), you'll probably want to continue by billing this to your clients (see this article). If you do so, the tracked time will be grouped by type, e.g. task type, meeting or call.
You will not see any details on the invoice, as you have the option to send a time tracking report along with the invoice. To open the timetracking report, simply click the arrow on top of the invoice and choose "Timetracking report".
If you then send the invoice (read this article for more information), you'll have the option to add the timetracking report as an attachment.
Much like other Teamleader documents, the timetracking report is also customizable. To do so, simply navigate to Settings > Document layout > Start setup > Timetracking report.
