If you haven't set up a payroll item rate for an employee, you can
still use that item in a paycheck:
Enter the hours in the item's column, and click OK to
clear the warning message.
When you are finished entering hours for all employees, select
Preview check before creating and then click
When you reach an employee with hours but no rate for a payroll item, select
the rate field next to the hours and enter a rate.
QuickBooks will multiply the rate you entered by the hours worked, add it to
any other amounts on this paycheck, and calculate taxes and withholdings.
