6. Difference between Periodic vs Perpetual Inventory
The periodic inventory system and the perpetual inventory system are two distinct approaches to managing inventory in a business. The primary difference between these systems lies in how inventory transactions are recorded and tracked.
The periodic inventory system involves updating inventory records periodically, typically at the end of an accounting period. Purchases and sales are recorded in separate accounts, and the cost of goods sold (COGS) is calculated only at the end of the period. This method requires a physical count of inventory to determine ending inventory and COGS.
On the other hand, the perpetual inventory system maintains real-time inventory records. Every purchase, sale, or return is immediately recorded in the inventory account, providing up-to-date information on inventory levels, COGS, and ending inventory. This system relies on the use of technology, such as barcode scanners and inventory management software, to track inventory movements accurately.
In summary, the key difference is that the periodic system updates inventory records periodically, while the perpetual system updates records continuously, allowing for more accurate and timely inventory management.
7. What is Perpetual Inventory?
Perpetual inventory is a method of tracking and managing inventory where the quantity and value of each item are continuously monitored and updated in real-time as transactions occur. This system provides a clear and up-to-date view of inventory levels, which helps businesses make informed decisions regarding purchasing, stocking, and sales.
Under the perpetual inventory system, each inventory item has a dedicated account in the general ledger. Whenever a purchase, sale, or return is made, the corresponding inventory account is immediately adjusted. This ensures that the inventory balance is always accurate, making it easier to determine the cost of goods sold (COGS) and ending inventory at any given point.
The perpetual inventory system is especially beneficial for businesses dealing with high-value or perishable items, as it helps prevent stockouts, reduces the risk of overstocking, and enhances overall inventory control.
8. Perpetual Inventory System Journal Entry
In a perpetual inventory system, journal entries are made to record inventory-related transactions in real-time. For example, when a company purchases inventory on credit, the journal entry would look like this:
Debit: Inventory Account
Credit: Accounts Payable
This entry reflects the increase in inventory (debit) and the corresponding increase in accounts payable (credit).
When a sale is made, the journal entry would involve reducing the inventory and recognizing the revenue. Here’s an example:
Debit: Cost of Goods Sold
Credit: Inventory Account
Credit: Sales Revenue
This entry captures the decrease in inventory (credit), the cost of goods sold (debit), and the revenue generated from the sale (credit).
These are just a couple of examples of the many journal entries involved in a perpetual inventory system, highlighting how inventory transactions are recorded in real-time.
9. How You Define Perpetual Stock?
Perpetual stock, also known as perpetual inventory, refers to the continuous and real-time tracking of inventory levels and values within a business. It involves the use of technology and systematic recording to monitor every inventory-related transaction, including purchases, sales, returns, and adjustments. The perpetual stock system provides an accurate and up-to-date view of inventory quantities and values at any given moment.
Businesses that adopt a perpetual stock approach maintain dedicated inventory accounts in their general ledger for each type of inventory item. These accounts are updated automatically as transactions occur, ensuring that inventory levels are always current. This enables businesses to make informed decisions about reordering, pricing, and overall inventory management.
The perpetual stock system offers several advantages, such as improved accuracy in tracking inventory, better control over stock levels, reduced risk of stockouts or overstocking, and enhanced financial reporting by facilitating the calculation of cost of goods sold (COGS) and ending inventory in real-time.
10. What is Perpetual System?
The perpetual system, also known as the perpetual inventory system, is an inventory management method that involves continuously and immediately updating inventory records as transactions occur. This approach provides a real-time view of inventory levels and values, making it easier for businesses to manage their inventory effectively.
Under the perpetual system, inventory transactions such as purchases, sales, returns, and adjustments are recorded in dedicated inventory accounts in the general ledger. This means that the inventory balance is always accurate, allowing for precise calculations of metrics like cost of goods sold (COGS) and ending inventory.
