Stock Counts and Inventory Controls: Getting the Evidence Right the First Time
An inventory count that fails audit scrutiny cannot be repeated after the year end. What the auditor needs to see, and how to plan the count so the evidence holds.
Inventory is the one balance where a missed opportunity cannot be recovered. If the year-end count is poorly executed, the auditor cannot go back in time. The consequences run from expanded testing and higher fees to a qualified opinion on a single line item.
For product businesses, distributors and manufacturers in the mid-market, the count is the single highest-stakes control event of the year, and it is often planned two weeks in advance by people who have other jobs.
What the auditor is actually testing
The count itself is not the objective. The auditor is testing whether your system quantity can be relied on, whether cut-off is clean, and whether the valuation applied to those quantities is supportable. Three separate assertions, three separate sets of evidence.
Planning the count
Write a count instruction document and circulate it before the day. It should specify the count date and time, who counts and who supervises, how the warehouse is divided into zones, how count sheets are controlled and sequenced, whether counting is blind, how recounts are triggered and how goods in transit and consignment stock are handled.
Freeze movements during the count. If a full freeze is impossible, document the movement log and reconcile it afterwards. Auditors accept controlled movement; they do not accept undocumented movement.
Use two-person teams where value is concentrated. One counts, one records. Independence from the day-to-day custodian of that zone matters more than speed.
Cut-off is where the errors live
Record the last goods received note number and the last despatch note number at the moment of the count. Almost every inventory misstatement traced during fieldwork comes back to these two numbers being missing or wrong.
Then test around them. Take the last ten receipts before the cut-off and the first ten after, and confirm each is recorded in the correct period. Do the same for despatches. Keep the workings.
Valuation and provisioning
Cost includes purchase price, import duties and the costs of bringing inventory to its present location and condition. It does not include storage of finished goods, administrative overhead or selling costs. Standard costing is acceptable if variances are analysed and material variances are allocated back.
Provisioning needs a policy and consistent application. Ageing bands with defined provision percentages are defensible. A single management estimate written at year end is not. Produce an ageing report at the count date and apply the policy mechanically, then document any override with a reason.
Cycle counting as the year-round alternative
Businesses with reliable perpetual systems can move away from a single disruptive year-end count. That requires evidence: a documented cycle count programme, coverage of high-value items several times a year, adjustment analysis showing accuracy rates and investigation of variances above a threshold.
If your accuracy rate is above ninety-five per cent by value and you can prove it across twelve months, the conversation with your auditor changes entirely.
The practical sequence
Six weeks before the count, agree the approach with your auditor. Four weeks before, circulate instructions and confirm attendance. Two weeks before, run a trial count on one zone and fix what breaks. On the day, control the sheets and record the cut-off numbers. Within five days, reconcile counted quantities to the system, investigate variances above threshold and post adjustments with an explanation attached.
Done this way, inventory stops being the item that holds up sign-off.
