Definition of Perpetual Inventory System
The inventory control method in which every inflow and outflow of stock are constantly updated, through an electronic point of sale system, is known as Perpetual Inventory System. The records maintained under this system are always up to date. In this system an inventory ledger is maintained to keep complete and continuous record of the receipts and issue of inventory in which the closing balance is the inventory in hand. The calculation of closing inventory can be done as under:
Inventory at the Beginning + Receipts – Issues = Inventory at the end
The inventory records are kept in Bin Card (Stores Keeper) and Stores Ledger (Cost Accounting Department). To ensure accuracy, physical verification of stock takes place at regular intervals, and they are compared with the recorded figures. If there is any shortage due to loss or theft, then it can be easily located, and corrective actions can also be taken immediately. Although the system is costly and complicated.
Definition of Periodic Inventory System
The inventory record system in which the movement of inventory is captured at a regular interval, say once or twice in a year, only after taking physical verification of stock is known as Periodic Inventory System. Normally, at the end of the financial year, the physical count of stock takes place after which the records are adjusted and updated accordingly. The following formula is used to track the cost of goods sold during the year:
Inventory at the Beginning + Purchases – Inventory at the end = Cost of Goods Sold
There are various shortcomings of this system as the amount of the cost of goods sold may include the goods lost or theft during the year. However, with the help of sales revenue, an estimation could be made regarding the lost inventory but this figure is not accurate. If the physical valuation of the stock is done more than once in a year, then this system can also cost higher. Discrepancies can be detected only at the end of the accounting period.
