Each industry is different in determining costs of goods sold or cost of services rendered. Retail uses two distinct methods to calculate costs of goods sold. The first is called ‘Specific Identification’ whereby each item sold is specifically identified to its recorded cost. The second method is referred to as ‘Inventory Adjustment’ format. In this method, a beginning and ending balance is recorded along with the purchases throughout the year.
Last In First Out
Last In First Out or LIFO is a variation of the inventory adjustment method of accounting for the ending dollar value of inventory.
