Physical Verification

Definition

Physical verification is the systematic physical counting, measurement, inspection or confirmation of inventory and comparison with the corresponding book or ERP balance.

Verification principlePlan → Freeze / Control Movement → Count → Record → Recount → Compare → Investigate → Approve → Adjust → Prevent Recurrence

Objectives

Establish physical inventory accuracy.
Identify shortages, excesses, wrong locations and unidentified stock.
Validate ERP balances and master data.
Detect transaction and process weaknesses.
Support financial and inventory reporting.
Provide evidence for authorized adjustments.

Verification Methods

Method	Application
Annual physical inventory	Broad or complete inventory verification
Cycle counting	Continuous verification of selected items
ABC counting	Higher frequency for high-value items
Criticality counting	Frequent verification of critical materials
Location count	Verification of all items within a location
Blind count	Counter does not see the book balance before counting

Counting Procedure

Define scope and counting schedule.
Issue counting instructions and responsibilities.
Control material movements during the count.
Prepare item and location lists.
Physically count or measure stock.
Record quantity, batch, serial and condition where required.
Perform independent recounts for discrepancies.
Compare physical and ERP balances.
Investigate root causes.
Authorize approved adjustments.
Verify corrective actions.

Variance Analysis

Quantity Variance = Physical Quantity − Book Quantity

Value Variance = Quantity Variance × Applicable Unit Value

Variances should be investigated before adjustment. Typical causes include unposted receipts, unposted issues, wrong UOM, location errors, duplicate transactions, counting errors, damage, unauthorized movement and master-data problems.

Controls

Use controlled count sheets or system count documents.
Separate counting from approval of adjustments where practical.
Require recounts above defined tolerance.
Maintain evidence of investigation.
Review recurring variance by item, location, department and process.
Do not use routine adjustments to conceal process failures.

KPIs

Inventory Accuracy

Items or quantities matching the book balance within tolerance.

Count Completion

Planned versus completed counts.

Variance Value

Value of identified discrepancies.

Adjustment Rate

Frequency/value of authorized inventory adjustments.

Common Errors

Counting while uncontrolled movements continue.
Counting duplicate locations twice.
Ignoring damaged or quarantined stock.
Using incorrect UOM.
Adjusting stock without root-cause investigation.
Failing to distinguish timing differences from true shortages.
