How I set entering billable time to the quarter hour in quickbooks online?
Appreciate the response however, I'm not sure this answers my question exactly. I enter my time using the weekly timesheet. There if I want to put in 1.75 hours it doesn't calculate as one and three-quarters of an hour. It assigns a off number to the time. I would like to make sure time is billed by the quarter hour. .25, .5, .75. How do I do that so I don't get times that are .10, .15, .40 etc? Thanks!
