I used a vendor for hosting my condo on Airbnb. But I am having trust issues now for some reasons as I have no access to how much they are getting paid through airbnb for the listing of my condo. How can I get access to what airbnb is paying my vendor as I am the owner and we have an agreement on the percentage I should be getting from the payout.
You have no access to this information, as it is not within your account. There are other ways to have a "joined" hosting construction, like the host/admin and co-host options. Consult the HELP files for this for more details.
