Hi there, @jeff128.
Currently, the option to add a payroll feature in QuickBooks Online Mobile App is unavailable. You may do the payroll using a web browser.
To know more details about the available feature in QB Mobile App, you can check out this article: Compare mobile app features.
For future reference, you may consider checking out our Resource page: Help Articles.
I'll be here if you have other questions. Let me know in the comment section and I'll help you further. Take care.
