What is the most effective method for determining the current amount of inventory in real-time?

The most effective method for determining the current amount of inventory in real-time is digital inventory tracking. This method utilizes software and technology to provide an accurate and up-to-date overview of inventory levels as transactions occur. It efficiently tracks stock levels, sales, and shipments, allowing for immediate updates to be reflected in the inventory database. In contrast, while physical counts provide a snapshot of inventory at a specific moment, they are time-consuming and do not reflect real-time changes. Estimated calculations may lead to inaccuracies due to reliance on assumptions rather than actual data. Customer feedback does not provide reliable information about inventory levels since it is subjective and can vary widely. Thus, digital inventory tracking stands out as the most effective approach in maintaining accurate and real-time inventory information.
