Can I set billable tasks?
In PushWork you can choose if you want a specific time entry to be billable or not when you start it. You can set the currency in details page and hourly rate in team page of workspace. In the web app, simply click on the dollar sign to mark it as billable. Similarly, you can make earlier entries billable.
You can also create different projects and determine which of their subtasks should be billable. Time tracked under the billable projects or their billable tasks will automatically be added up as billable time.
