I appreciate you for adding a post here in the Community. I'm here to share with you some information about the payroll services offered by QuickBooks Online (QBO).
At this time, QuickBooks offers the newest payroll services which are the Payroll Core, Premium, and Elite. Each plan has an exact rate and an add-on fee per employee per month. If you have one employee, then you'll only be paying for the payroll subscription and an additional fee for the employee per month.
Once you're subscribed to payroll, you may open the topics from this article for more hints about processing paychecks and handling payroll forms and taxes: Help on common payroll topics.
If you have any other questions about payroll or QuickBooks, please let me know by adding a comment below. I'm always here to help. Keep safe!
