To clarify,

We have 2 companies each in their own QB file.

However, we use 1 cc for both (different users).

Company A is in a QB file with the CC.  Company B is in a separate QB file without the cc.

However, company B still has to pay off some of the CC.

This being said, how do I record the payments from company B, if I can't pull up the bank account that is making the payment in company A's file?

Does it make sense to create a fake bank for company B in company A's file?

I still can't figure out what would be the best way to go about this.

Thank you
