Which of the following is an advantage of the Perpetual Inventory Method?

The advantage of the Perpetual Inventory Method is that stock levels are always up to date. This system continuously tracks inventory balances in real-time as sales and purchases occur. This immediate updating provides businesses with accurate and current information about their inventory levels, allowing for more effective management decisions regarding restocking, sales strategies, and inventory turnover.

In contrast, the other options, while they may have their own merits in different contexts, do not accurately describe the benefits of the Perpetual Inventory Method. For example, this method typically requires a higher initial investment in technology and systems capable of supporting continuous tracking, which contradicts the idea of a lower initial investment. Additionally, the Perpetual Inventory Method may necessitate more extensive training for staff to effectively use the system, rather than less. Lastly, because the method involves real-time updates, sales records are inherently linked to inventory management and must be updated continuously to reflect accurate stock levels, making the statement about not needing to update sales records incorrect.
