SECTION VIII AIDING AND PROTECTING BUSINESS Discounts A person with a small capital would not be able to engage in mercantile business were it not for the time allowed him to pay for the goods in which he deals. In order, however, to secure prompt payment, and to reduce the risk of carrying his account, the seller frequently deducts a certain per cent for the payment of a bill before it is due. This is called a cash discount. The bill generally states the time of the credit with the allowance for earlier payment. In the following bill, the credit is 60 days, with a reduction of 2% if the bill is paid within 10 days. Written Exercises 1.
