Robert,
I don't believe your merchant will allow you to have two companies on the same merchant account (use two different names).
I have asked my merchant account (humboldt bank) in the past about that and they told me that I would have to start a new merchant account for the second company.
But, what your merchant account doesn't know won't hurt them.
If you wanted to use one merchant account for two companies than both will show up as the same business name ("Bali Kingdom"). Something you can look into is a generic name for your multiple companies.
I currently use "Douglas Foster Enterprises" for my multiple companies so I can use my one merchant account. I may soon switch to "oxx enterprises" and I just let customers know at checkout and on their invoices that they will be charged by "Douglas Foster Enterprises" and before they finish the checkout they must agree that they know (checkout question).
I wish you good luck, I would say one merchant is a much better way to go.
P.S. You must always remember that with multiple companies on one merchant account means more money being charged. So, make sure that your merchant account limit is set high enough. I just received a call from our merchant account two days ago complaining because we charged $5,000 more than our limit already this month. They don't like the extra liability but in most cases are willing to up your limit.
