Regarding multiple ownership?

Sorry if this is in the wrong spot, but couldn't think of where to post.

I have actually been wondering the past few days and figured that I may as well just ask...my friend and I are actually going into business together with ball pythons and have been splitting the costs of everything. This is where the 'MCMB' comes from (Madame Chong and Mr. Burgers). From what I understand, the TOS states that you can't have two people posting under one account, but is this waived in the case of two people working together under the same business name? Or how would we circumvent that to avoid breaking any of the posting rules? Obviously we are not a certified business yet as we are still in the process of setting things up, but I am still curious as to how this works.

Thank you in advance for your responses.
