How do perpetual and periodic inventory systems compare in terms of fraud detection and reconciliation requirements?

• A. Perpetual systems have more detection risk; periodic systems are always accurate.
• B. Only periodic systems require reconciliations.
• C. Perpetual systems cannot detect misstatements.
• D. Perpetual records reduce misstatement risk; periodic systems have less timely detection; both require reconciliations.

Answer: (D)

The main issue is how the timing of updating inventory affects fraud detection and the need for reconciliations. In perpetual inventory systems, inventory and cost of goods sold are updated continuously as transactions occur. This ongoing tracking makes discrepancies between what’s recorded and what’s physically on hand easier to spot, so misstatements due to errors or theft are detected more promptly, reducing the risk of fraud going unnoticed. In periodic systems, updates happen only at the end of the period after a physical count, so many misstatements can linger for longer and detection is less timely. Reconciliations are necessary in both setups: perpetual systems involve reconciling the perpetual records with physical counts plus cycle counts to ensure accuracy, while periodic systems rely on a physical count at period end and a reconciliation to update inventory and COGS. So perpetual records reduce misstatement risk and offer more timely detection, whereas periodic systems have less timely detection; both require reconciliations.
