Question About previous earning for UK tier 1 from the USA

Hi all I really can use your help,

I have a question regards the previous earning section of the point calculator

My wife is going to apply for UK tier 1 general visa here in the US as self employed. She owns her own LLC company. her Company made xxxxx.xx dollars per month and she paid all business related expenses from the company bank account. she also used the business bank account for her personal use (she wrote checks for bills and staff from the business account so no personal bank statements.) is it enough proof is she submit
1. The business bank accounts showing earnings, withdrawls and checks amounts?
2. A letter from her accountant stating the company net profits and her monthly owner draws (in the amount of the total checks she wrote)
3. business P&L and BS.

in the USA a pass true LLC does not pay taxes. the profit or loss is added to the owner personal return. and we have not filed yet.

your advice will be greatly appreciated
