A way to seperate billed hours from non-billed hours
Perhaps there is a way to do this already.. I often bill hours here and there, sometimes a side project will have a few hours here and there that I only bill at the end of a month or quarter. I need to be able to separate invoiced hours from non-invoiced hours when I create invoice or at least on the timesheet report. I suppose I could make a note on a task when I've billed for it.. but thats not very elegant.. and I know I'll forget.
Any suggestions?
