Ace AAT Level 4 External Auditing 2026 – Audit Your Way to Success!

The main idea is to ensure that the inventory balance reported by the company actually exists at the reporting date. Inventory is prone to overstatement if items recorded as on hand aren’t physically there, so auditors focus on confirming the existence of stock through physical counts, direct observation in the warehouse, and reconciling the counted quantities with the inventory records. This verification helps prevent assets being misstated simply because they were imagined or fictitious.

While other assertions matter for inventory—such as that the entity has the rights to the stock (rights and obligations), that the amount is measured properly (valuation), and that all existing inventory is recorded (completeness)—the risk most directly tied to the balance sheet amount is whether the inventory actually exists. If existence isn’t demonstrated, there’s no point in assessing valuation or rights, because the asset itself may not be real.
