A sound inventory closing file does not begin with an adjustment entry. It begins by asking whether the movement from opening to closing inventory can be explained. A system report alone repeats the number without establishing its components. The file needs connected evidence about quantities, costs, rights, condition and transactions near period end.
This article proposes a practical working method, not a sequence prescribed verbatim by a single standard. Inventory measurement rests on IAS 2, while relevant subsequent information is assessed under IAS 10. Connecting each procedure to its purpose prevents closing from becoming signature collection without substantive review.
One page explaining the value movement
Start with an overall reconciliation and make every line traceable to detail. In a simplified educational example, opening inventory is SAR 400,000, net purchases and eligible added costs are SAR 1,200,000, and cost of sales is SAR 1,050,000. The expected balance before other differences is SAR 550,000.
If review establishes a quantity loss costing SAR 5,000 and a separate SAR 20,000 write-down, closing inventory becomes SAR 525,000. Assume no other movements. Each difference needs evidence and explanation, not a SAR 25,000 account described as “balancing adjustment.”
| Reconciliation step | Amount in SAR |
|---|---|
| Opening balance | 400,000 |
| Net eligible additions | 1,200,000 |
| Cost of sales | −1,050,000 |
| Approved quantity loss | −5,000 |
| Separate write-down | −20,000 |
| Closing balance | 525,000 |
Four evidence groups behind the number
Quantity evidence connects count sheets to locations, items and units of measure, with recounts of important differences and explanations of movements during counting. A carton-to-unit conversion error should not be treated as lost goods before the conversion is checked.
Rights and cutoff evidence covers goods held elsewhere, consignments, transfers and shipments near year end. Reconcile receiving and delivery timing with contractual terms and documents so that invoices, inventory and cost of sales do not land in inconsistent periods without justification.
Cost evidence examines completeness of purchasing costs, allocation, the approved cost formula and backdated movements. Select samples that can be independently recalculated and examine late invoices relating to held or sold goods. Agreement between ledger and subledger totals does not by itself demonstrate accurate underlying cost.
Condition and valuation evidence covers damage, slow movement, expiry, selling-price support and necessary costs. Do not use one blanket reduction to cover every inventory item unless analysis supports it. Different products and circumstances may need distinct assessments.
What can undermine an orderly-looking file?
All documents may be present while their versions are inconsistent: a count sheet before a transfer correction, a cost report after it and a ledger extract before the write-down was posted. Record each report's extraction date and scope, then reconcile again after approved entries. Identify the final version so that another reviewer can reproduce the same result.
Maintain a separate open-issues list with an owner, deadline and potential effect. An unconfirmed invoice should not disappear from the list merely because the closing deadline approaches. A clear unresolved matter and its information limits are better than a temporary entry nobody is assigned to revisit.
Before approval, review sales, returns and technical reports received after period end. Determine whether they reveal a condition existing at close or a new event. The exercise does not move every subsequent event into the previous year; it places evidence where it belongs.
Finally, ask someone who did not prepare the file to trace one item from count to cost to final balance. If they cannot, find the missing connection before seeking their signature. A successful file should not require a lengthy oral explanation every time. It should provide a clear route from physical goods and documents to the number supporting the financial statements.
