Answer:
Certain accounts that are maintained exclusively by trading businesses include purchases, purchase returns, purchase discounts, freight on purchases, sales, sales returns, and sales discounts.
A purchases account records the transactions of purchasing stock or inventory, which is resold later. In case the stock is defective, it can be returned to the seller (manufacturer). This transaction is recorded in the purchase returns account. Sometimes, the trading business (buyer) may get a discount on goods purchased from the manufacturer (seller) for making an early payment. This discounted amount is recorded in the purchase discount account. Purchase discounts and purchase returns are both contra-expense accounts. A trading business may have to spend money for transportation of goods. These expenses are recorded in the freight on purchases account.
A sales account records the revenue earned from sale of products. Transactions relating to goods returned by customers are recorded in the sales returns account. Sales discounts offered by a trading business to its customers are an expense for the business and are recorded in the sales discounts account. Sales discounts and sales returns are both contra-revenue accounts.
