perpetual inventory system and periodic inventory system
*in a perpetual inventory system, a continuous record is kept for the cost of goods sold and the cost of stock on hand. it is usually employed for items that have high selling prices and costs that are easily determined. when a sale occurs and a perpetual inventory system is used, two journal entries must be made at the same time, namely one journal entry to record sales and another entry to record cost of sales.
**a periodic inventory system is used when items are sold at a very low rice, when the cost of the individual items is not easily determined, or when high volumes of items are sold. cost of goods sold can only be determined by counting the unsold items in the warehouse at the end of the accounting period. under the periodic inventory system, the amount in the stock account remains unchanged during the accounting period.
