How to record only my Commission (net receipt) in as Income

Hi,

I am an agent and new to QuickBooks. 

I receive payments on behalf of Authors from Publishers. I deduct my commission and then pay the rest to the Author. 

Say, I receive £100 from the publisher, my commission is 10%, I would then pay the Author £90.

On the bank statement, it would show £100 coming in and £90 going out.

My Income  on the P&L should only be the £10.

How do I enter these transactions in QuickBooks to reflect this?

Also, I would need to send the Author a remittance advice showing the £100, less £10 Net £90

Is this possible?

Thanks
