Only the QuickBooks Administrator can do this.
When you install QuickBooks, payroll is turned on by default. Depending on your company
needs, however, you may want to:
Turn payroll off if, for example, you have no employees or you use another
program to track your payroll.
Turn payroll on if you had previously turned it off.
Open the Payroll and Employees preferences.
Select Full payroll to access all the payroll features in QuickBooks.
Select No payroll to turn off all payroll features in QuickBooks.
