If overhead was a poor word to use, then how about this for project breakdowns,

I need my projects in QB to look something like this:

Job Invoiced total: $1,000

- company initial commission 15%: $150

= $850

- labor: $100

= $750

- materials: $100

= $650

- commissions to salesman 50% = $325

= $325

- commissions to owner = $325

= $0

How can I put in the company commissions 15% without it being taken out of any bank account?
