Hi there eliva13-ca-gmail,
Thanks for reaching out about editing your employee's pay periods. QuickBooks Online Payroll is a great tool able to help you pay your employees for the hours they've worked. I can provide some information about changing the pay period for your employee.
To change the pay period for an employee, go to the Payroll tab, then Employees. Click on the name of the employee in question, then scroll down to Employment details. Click on edit in that section, then in Pay schedule, you can either select a preexisting pay schedule, or add a new one. Don't forget to Save
If you have any other questions, feel free to reach out here.
