Under the periodic inventory system, the purchases account is used to record
|
A periodic inventory system is a form of inventory valuation where the inventory account is updated at the end of an accounting period rather than after every sale and purchase. Show
The method allows a business to track its beginning inventory and ending inventory within an accounting period.

The yearly inventory purchases are recorded in the purchases account, which is a ledger listing all inventory purchases and their costs. Debit Credit Purchases xxx Accounts payable xxx At the end of the year, a physical inventory count is done to determine the ending inventory balance and the cost of goods sold. Debit Credit Inventory xxx Purchases xxx How Do You Calculate Cost of Goods Sold Using the Periodic Inventory System?The total in purchases account is added to the beginning balance of the inventory to compute the cost of goods available for sale. The ending inventory is determined at the end of the period by a physical count of every item and its cost is computed using inventory calculation methods such as FIFI, LIFO and weighted averages. This amount is subtracted from the cost of goods available for sale (or the cost of goods manufactured) to compute the cost of goods sold. The general formula to compute the cost of goods sold under the periodic inventory system is given below: Cost of goods sold (COGS) = Beginning inventory + Purchases – Closing inventory For example, XYZ Corporation has a beginning inventory of $100,000, has $120,000 in outgoings for purchases and its physical inventory count shows a closing inventory cost of $80,000. The calculation of its cost of goods sold is: Cost of Goods Sold = Cost of Goods Available – Closing Inventory Advantages of the Periodic Inventory SystemEasier to ImplementSince the periodic system involves fewer records and simpler calculation than the perpetual system, it is easier to implement. The simplicity also allows for the use of manual record keeping for small inventories. Ideal for Small BusinessesThe periodic inventory system is ideal for smaller businesses that maintain minimum amounts of inventory. The physical inventory count is easy to complete, small businesses can estimate the cost of goods sold figures for temporary periods. While the system may work for smaller businesses, it can prove to be highly problematic for large businesses due to its high level of inaccuracy. Since the periodic system is manual, it’s prone to human error and the inventory data can be misplaced or lost. The periodic inventory system doesn’t provide real-time data about the cost of goods sold or ending inventory balances. This makes it harder to ascertain the inventory on hand at any point in time. Most accounting software use a perpetual inventory system to track and update inventory purchases, sales and the cost of goods in real time. This way business owners are able to keep track of accurate COGS figures and adjust for obsolete inventory or scrap losses. The general ledger account Purchases is used to record the purchases of inventory items under the periodic inventory system. Under the periodic system the account Inventory will have no entries until it is adjusted at the end of the accounting year so that it reports the cost of the ending inventory. Under the periodic system, the cost in the account Purchases will be added to the cost of the beginning inventory to arrive at the cost of goods available. The cost of the ending inventory is computed through a physical count (or an estimate) and is subtracted from the cost of goods available to arrive at the cost of goods sold. Inventory Account Under the Perpetual Inventory SystemThe account Purchases is nonexistent with the perpetual inventory system. Under the perpetual inventory system, the cost of inventory items purchased are recorded directly into the account Inventory. Under the perpetual system, the costs of the goods sold are removed from the account Inventory when the goods are sold and are recorded in the account Cost of Goods Sold. As a result, the balance in the account Inventory should be the cost of the ending inventory. The periodic inventory system uses an occasional physical count to measure the level of inventory and the cost of goods sold. Periodic InventoryThe periodic inventory system is often used by smaller businesses that have easy-to-manage inventory and may not have a lot of money or the opportunity to implement computerized systems into their workflow. As such, they use occasional physical counts to measure their inventory and the cost of goods sold (COGS). COGS is an important accounting metric, which, when subtracted from revenue, shows a company's gross margin. The COGS under the periodic inventory system is calculated as follows: COGS = Beginning Balance of Inventory + Cost of Inventory Purchases - Cost of Ending Inventory
Since businesses often carry products in the thousands, performing a physical count can be difficult and time-consuming. Imagine owning an office supply store and trying to count and record every ballpoint pen in stock. Now multiply that for an office supply chain. This is why many companies perform a physical count only once a quarter or even once a year. For companies under a periodic system, this means that the inventory account and cost of goods sold figures are not necessarily very fresh or accurate. The cost of goods sold includes elements like direct labor and materials costs and direct factory overhead costs. Perpetual InventoryThe perpetual inventory system keeps track of inventory balances continuously. This is done through computerized systems using point-of-sale (POS) and enterprise asset management technology that record inventory purchases and sales. It is far more sophisticated than the periodic system of inventory management. Perpetual inventory is a highly detailed system. Changes in inventory are accurate (as long as there is no theft or damage to any goods) and can be easily accessed immediately. The COGS account is also updated continuously as each sale is made. The information collected digitally is sent to central databases in real-time. Because it involves the use of technology, it requires very little effort from businesses (if at all):
This type of inventory system can be very costly because of the cost associated with implementing and maintaining the infrastructure. Using the system is much easier and simpler than the periodic system. Not only does it allow for real-time monitoring, but perpetual inventory is also much more accurate than physical counts. And since each product has a barcode attached, companies can get more detailed information about everything that goes in and out of their warehouses. At a grocery store using the perpetual inventory system, when products with barcodes are swiped and paid for, the system automatically updates inventory levels in a database. Key DifferencesOne of the main differences between these two types of inventory systems involves the companies that use them. Smaller businesses and those with low sales volumes may be better off using the periodic system. In these cases, inventories are small enough that they are easy to manage using manual counts. The perpetual system may be better suited for businesses that have larger, more complex levels of inventory and those with higher sales volumes. For instance, grocery stores or pharmacies tend to use perpetual inventory systems. The technological aspect of the perpetual inventory system has many advantages such as the ability to more easily identify inventory-related errors and can show all transactions comprehensively at the individual unit level. Some of the other main differences between these two types of inventory management are:
Under the perpetual system, managers are able to make the appropriate timing of purchases with a clear knowledge of the number of goods on hand at various locations. Having more accurate tracking of inventory levels also provides a better way of monitoring problems such as theft. What Is More Effective, Perpetual Inventory or Periodic Inventory?The perpetual system is generally more effective than the periodic inventory system. That's because the computer software companies use makes it a hands-off process that requires little to no effort. Products are barcoded and point-of-sale technology tracks these products from shelf to sale. These barcodes give companies all the information they need about specific products, including how long they sat on shelves before they were purchased. Perpetual systems also keep accurate records about the cost of goods sold and purchases. Should My Business Use Perpetual Inventory or Periodic Inventory?The nature and type of business you have will factor into the kind of inventory you use. It may make sense to use the periodic system if you have a small business with an easy-to-manage inventory. You can make updates to your accounts manually using this system. If you have a larger company with more complex inventory levels, you may want to consider implementing a perpetual system. The software you introduce into the workflow will make it easier for you to update and maintain your inventory. What Are the Disadvantages of a Periodic Inventory System?There are several disadvantages of using a periodic inventory system. It can be cumbersome and time consuming as it requires you to manually count and record your inventory. And because this is a physical count, there is a higher chance of error. It also isn't as updated as a perpetual system, as it is done at periodic intervals rather than continuously. Does Amazon Use Periodic or Perpetual Inventory?Amazon uses a perpetual inventory system. That's because of the sheer volume of goods that go in and out of its warehouses. In what account are purchases recorded when the periodic inventory system is used?Under the periodic inventory system, all purchases made between physical inventory counts are recorded in a purchases account.
What is used to record purchases on account?A purchase journal is used to record and summarise all purchases made in a given month or period. Purchases can be merchandise inventory for resale, materials used to render a service, raw materials used in manufacturing, and other types of purchases in connection with the nature of the business.
What account is debited to record the cost of merchandise purchased under the periodic inventory system?Under the periodic system, merchandise purchases are recorded in the purchases account, and the inventory account balance is updated only at the end of each accounting period.
Does periodic inventory Use purchases?In a periodic inventory system, no continuous record of changes is kept. The yearly inventory purchases are recorded in the purchases account, which is a ledger listing all inventory purchases and their costs.
