CEVAP:

Two entries are required to record sale transactions:
• The first entry is necessary to record the earned sales revenue: The seller increases (debits) Cash (or Accounts Receivable, if a credit sale), and also increases (credits) Sales Revenue for the invoice price of the goods.
• The second entry records the expense side of the sales event (the cost of the merchandise sold): The seller increases (debits) Cost of Goods Sold, and also decreases (credits) Merchandise Inventory for the cost of those goods
