I dont understand your goal @AYRHVAC
I got this: You have and are the owner of a verified listing. Thats fine so far.
But what do you mean or trying to achieve "for another company that I am allowing access to my site."
Please elaborate what you mean accessing any listing of an other company to your site.
I don't get this wording
