What about the first page of the financials showing Assets/Liabilities being balanced to the penny. Does that not strike you as strange. Do you often see a balanced budget in a startup?
Do you know what a balance sheet is? Assets = Liabilities + Owner's Equity.
I hope you business does well, because if you cannot balance your Assets, Liabilities and OE (to the Penny), then you will be in for quite a surprise at tax time.
I would also start checking staff pockets for the cash that is not hitting the books.
