Once you have made a firm commitment in writing to your vendor of choice, you cannot gain any advantage by paying them late or withholding funds. You ultimately must pay your bills, so you might as well pay on time to avoid establishing two potentially fatal business sins: a bad reputation and bad credit.
Many people try to establish deal leverage or try to get an underhanded credit float by paying bills late. This approach will backfire, is a waste of time and proves you are not paying attention to the critical tasks your time requires. There is no reason to upset vendors and force them to hold you in disdain for paying them late. If you need a loan, get one from a lender, or ask the vendor if they will provide special terms or financing.
