In accounting terms, operating expenses, or OE, and cost of goods sold, or COGS, are both considered expense accounts. In short, they measure different ways in which resources are spent in the process of running a business.
Cost of Goods Sold. The cost of goods sold, or COGS, is the cost of the products or merchandise actually sold to customers. COGS includes the cost your company incurred to purchase or create the physical inventory plus any additional direct labor, supply or shipping and transportation costs. When your company sells a product, the revenue and its corresponding COGS appear on the income statement.
