As a management company you should help the owner to set the listing up under their profile and then add you as a cohost.
The owner can then add in the percentage for you to be paid for whatever commission you have agreed will be paid for your services.
Why would you need to pay the host when the Airbnb system is already set up for the host to retain the income for their property and for you to be paid the commission agreed for your support.
If you are going to promote yourself as a property management company you really need to familarise yourself with how Airbnb works before promoting your services to potential clients.
