"I'd like to get this sorted out in one go so I can avoid repeatedly asking the owner for more information. I wasn't quite sure what the best way to deal with this, so I wanted to get some input on this."
Not much that you can do except give him the cc statement and ask that he label each transaction as either Business A, B, or personal. It's best to have Business A pay for their charges, Business B pay for their charges, and the owner pay for the personal charges out of their personal account. LLC's should not be paying for owner's personal expenses (even if recording them to their equity account) as this risks losing the liability protection that the LLC was created to provide.
