If I missed including an employee in a previous pay period, can I retroactively create a pay cheque for him?

Hi gamebreakers, 

QuickBooks makes it easy to pay your staff, even if it's retro-active pay. Rest assured, I'll be glad to provide the steps you need in order to create a paycheque for your employee.

Here's how you can process the cheque you've described above:

1. Select Payroll >  Employees from the left side menu
2. Select Run payroll
3. Under Pay period, select the correct dates from the drop down menu
4. Select the Pay date (keep in mind that you cannot enter a date that is earlier than the date you first started using the QuickBooks Online Payroll service)
5. Input the pay details as needed
6. Select Preview payroll
7. Select Submit payroll
8. Select Finish payroll

Give this a try and let me know how you make out. I'll be one message away in case you need anything else.
