I believe the issue is that the "Billable rate" box was unchecked under QB Time / Preferences.

This will, at least, allow the employee to enter a billing rate.

Checking the "Billable Rate" box in Preferences will then get the check box to show when entering time.

As the time is approved and brought into QBO a billing rate will be assigned with the time entry.

However, I would like for the employees to not have to enter their Billable Rate on every entry, as this is prone to entry errors and is unnecessarily time consuming.  QBD Professional Services used to do this with Billing Rate Level Lists that were assigned to the employee.  Is there a way to assign a billable rate to an employee and avoid entering their Billable Rate on every entry?
