I've got your back on processing off-cycle payroll in QuickBooks Online. QuickBooks allows you to create unscheduled checks to process additional payroll. To do so, you can follow the steps below:
Sign in to your QBO account.
Click Payroll from the left menu, then select Employees.
Select Run payroll.
Find the employee you want to pay and choose Create another check.
Enter employee compensation, including any salary adjustments, vacation or sick hours, and other pay types.
Confirm the pay period and check date.
Select Preview Payroll, and then select Submit payroll.
You might want to run payroll reports in your QBO. This will help you view useful information about your business and employees.
Our doors are always open to help you again if you have any other concerns or follow-up questions about adding extra payroll. It’s nice to work with you, @nyron-cameron.
