Hi there @Andrei Borodin! I wanted to follow back up here to share what I found while digging in further. It appears that error is happening because you're using a version of QuickBooks Online Payroll that is currently incompatible with QuickBooks Time. At the moment, QB Time only integrates with QuickBooks Online Payroll Premium or Elite. 

You will still be able to use both products and can export reports from QuickBooks Time to bring the data to QuickBooks, but unfortunately, we won't be able to integrate them to perform that automatic sync. 

If you'd like any more information on how to navigate getting information back and forth, or if you want to explore other payroll options, please don't hesitate to let me know! I'm here to help with whatever is best for you and your business.
