I have the same problems. Our Rest. use POS system and published daily activities to QuickBook online.

We use QuickBook payroll services.

At the end of the month, in P&L we have payroll records with Gross pay/Tips pay/ ER taxes accordingly; at the  Balance Sheet side, we have Undistributed Tips WH.  If my Journal Entry is to Dr. Undistributed Tips WH and Cr. Wages Expenses, that will lower the total Payroll expenses. 

How do I fix this problem?   

Thanks

Sandy
