Hi cbkamma

You have to run Time tracking by employees report for the payroll period and export to excel, then run pivot table report to get the hours by classes that you need. Remember that your employees have to enter hours by classes in their timesheets in order that you can run this report. If they do not add classes to their hours, there is no way to run hours by classes in QBO.

Hope it helps. Please let me know if any questions

Best,

Anthony
