Thank you for your comprehensive response. I agree, when you enter time in tenths of an hour directly into an invoice, the invoice will print in tenths of an hour. However, the problem occurs when I enter a single time activity for a client in tenths of an hour. When I add that billable time to an invoice, the printed version of the invoice converts it to hours and minutes. For example, if I bill a client .3, on the printed invoice it shows as 0:18. Is there any way to prevent this from happening?
