Is there a way to create a paycheck for last month?

Hi there, @wilberpt.

Yes, create an unscheduled check in QuickBooks Online Payroll. This way, you can pay your employee out of your regular payroll run. Here's how:

1. Go to the Payroll menu and select Employees.
2. Click Run payroll.
3. Find the employee you want to pay, and then select Create another check.
4. Enter employee compensation, including any salary adjustments, vacation or sick hours, and other pay types.
5. Confirm the pay period and check date.
6. Click Preview Payroll, and then select Submit payroll.
7. If you're creating a paper check, handwrite or print the check and give it to the employee by the check date.
8. Select Finish payroll.

For complete guidelines, you visit this article: Create unscheduled checks in Online Payroll.

There are also several payroll reports you can use to view useful information about your business and employees. You can check the functions of these reports in this article: List of payroll reports available in QuickBooks Online Payroll.
