We do payroll each Wednesday. We input all the service tech’s time through Edit Time Entries in Service Management based on what they turn in on their time cards that morning. From there the time is sent to Payroll where we enter and process the checks. We have been told that we should not do any billing during the payroll process as is can impact the process. However, I'm not sure what it would impact as we have never done billing during payroll since I've been here.  I’m attempting to do some research on why we should not do this and if there is any reason why we can’t. Has anyone else had this situation?
