Q: I own a small business and have several large corporations as customers. One corporation offers payment in 15 days with a 2.5 percent discount or in 30 days with a 2 percent discount. I have opted for the 2 percent, 30-day deal. When I receive the check, however, I note they take a discount not only on my merchandise but on my sales tax and delivery charges.
