Hi matt240,
Thanks for posting in the Community!
The QuickBooks Online Mobile app is a simplified version of the software when accessed through a web browser. Payroll feature is unavailable in the mobile application at the moment. To get the best experience and be able to process payroll, we need to log in using a web browser like the Google Chrome or Safari browser.

Post again in the Community if you have other concerns. I am around to help you.
