Need Payroll summary by job

How do I run a payroll summary by customer/subcustomer in QBO?  I need to be able to see the total wages to each job (customer/subcustomer) each month for accrued payroll entries. 

I found a report "Time Activities by Employee" that has the employee, job and hours, which is great, but no rate or amount.  I can see in each employees detail they have a set hourly rate, but it is not pulling into this report.  Is that because it needs to be set up somewhere in "Time"?

I don't currently have my jobs set up as projects, they are just customer/subcustomer.  Would setting up as projects give me the report I'm looking for?  Would setting up as projects give me better reporting or any real advantages over customer/subcustomer setup?  I just hesitate to start converting current jobs to projects and create a mess.
