Answer:
Although UCC 4-205 might cover the bank, I argue in favor of requiring the customer to endorse the check as it is made out (in the business name). If he wants, he can sign his name under that, but that would not be necessary if the check is going into an account captioned with the business name (in addition to the sole proprietor's name).
