Hello, 

Thanks for reaching out to the Community for help. I'll shed some light on the key differences between QuickBooks Online and QuickBooks Self-Employed. 

QuickBooks Self-Employed doesn't have the ability to integrate with third-party applications, and can't be integrated with TSheets. The Self-Employed platform is also designed for an independent person that runs a business without any employees. TSheets is designed to help you streamline employee hours. 

If you're looking to utilize the TSheets app, I recommend staying with QuickBooks Online. This platform has the ability to sync with tons of different third-party apps. 

I hope this helps. If you have any other questions, just let me know. 

Have a good day.
