Which system scans items at sale and automatically deducts from inventory?

• A. Perpetual inventory system
• B. Periodic inventory counting
• C. Set order points system
• D. Point of sale system

Answer: (D)

A point-of-sale system is designed to scan items at the moment of sale and automatically deduct those items from inventory. This ties the checkout process directly to stock levels, giving real-time updates so the inventory count reflects every sale as it happens. A perpetual inventory system, while it tracks inventory continuously, requires the proper data flow from sales to inventory records and can be implemented with a POS, but the act of scanning at checkout and updating stock in real time is the hallmark of a POS system. A periodic inventory counting method updates stock only after physical counts at intervals, so it does not automatically deduct items at the moment of sale. A set order points system focuses on when to reorder stock rather than updating inventory counts during each sale.
