Can payroll set in the practice be moved to a company?

HHi there, 

Welcome to the Community. It's great to learn you're using QuickBooks to help streamline your work. Rest assured, I'll be happy to share more info and help steer you in the right direction.

Based on what you've described above, you'll have to manually migrate your data from one account to the other. QuickBooks Online allows you to export your some of your data. Here's a helpful article that shows you how to: Export some of your data. For importing your data to the other account, I encourage you to check out this helpful article as it shows you how to: Import your data into QuickBooks Online.      

You're also more than welcome to look into third-party migration apps on our app store by visiting http://www.apps.com. I recommend choosing an app that suits your business need based on the app description and reviews.   

Feel free to ask other questions, I'm here to help guide you in the right direction.
