SMALL NOTE: ON THAT 30 DAY OAY PERIOD Most business pay on a 30 day pay period NORMALLY. Some that are tight on cash pay on a 45 or even 60 day pay cycle. Ask anyone who works in a company ACCOUNTS PAYABLE Department. On the other side , if you are selling to a questionable company , you hold off shipments in leu of payment via CIA (CASH IN ADVANCE). BP is good for the money currently.
