What is the inventory system in which the inventory records do not show the amount available for sale?

The inventory system where inventory records do not show the amount available for sale is known as the "periodic inventory system." In this system, inventory levels are not continuously updated with each transaction; instead, physical counts of inventory are conducted at specific intervals, typically at the end of an accounting period. This means that sales and purchases are recorded, but the actual quantity of inventory on hand is only determined during these periodic counts. As a result, real-time inventory data is not available, which can complicate inventory management.
