How often should 100% physical inventories be conducted?

• A. Monthly
• B. Quarterly or as often as required to maintain 100% inventory validity
• C. Annually
• D. Biannually

Answer: (B)

The key idea is keeping inventory records fully accurate by verifying every item in stock through a complete physical count. Conducting a 100% physical inventory on a regular cadence ensures the recorded quantities match what’s actually on hand, and any discrepancies are found and resolved promptly.

Doing this quarterly provides a practical balance: it’s frequent enough to catch and correct variances before they grow, while not being so frequent that it becomes unnecessarily burdensome. The phrase “as often as required to maintain 100% inventory validity” emphasizes that the timing should be driven by the need to keep records completely accurate. If a prior count reveals issues, the frequency should be increased to restore validity; if records remain accurate, the cadence can continue as quarterly.

Choosing monthly would be more than typically required for full counts and can be costly; annually or biannually risks letting discrepancies accumulate and undermines accuracy.
