Stock Audit

Stock Audit: Importance, Objectives, Process and Benefits

A stock audit, also known as an inventory audit, is a systematic examination and verification of inventory maintained by a business. It generally involves comparing physical quantities of stock with inventory recorded in the books of accounts and investigating significant differences.

However, stock audit is not limited to physical counting. Depending upon the scope of the assignment, it may also involve reviewing inventory valuation, storage practices, documentation, movement of goods, obsolete and slow-moving inventory, internal controls and compliance with applicable accounting requirements.

Stock represents a significant portion of the working capital of many manufacturing, trading and retail businesses. Therefore, discrepancies in inventory can directly affect profitability, financial reporting, working capital and even borrowing limits.

What is a Stock Audit?

Stock audit is the process of examining inventory records and comparing them with the actual inventory available at warehouses, factories, stores or other business locations.

Stock Audit vs Physical Stock Verification

Physical stock verification primarily involves counting or measuring the inventory physically available.

A comprehensive stock audit may go considerably further and examine:

• quantity of inventory;
• inventory records;
• valuation;
• purchase and sales cut-off;
• goods in transit;
• damaged inventory;
• obsolete inventory;
• slow-moving inventory;
• storage conditions;
• inventory controls; and
• reconciliation of differences.

Therefore:

Physical Verification = Checking Quantity

Stock Audit = Quantity + Records + Valuation + Controls + Risks

Why is Inventory Important?

Inventory can include:

• raw materials;
• work-in-progress;
• finished goods;
• stores and spares;
• consumables;
• trading goods; and
• other materials held for business purposes.

Errors in inventory can affect both the balance sheet and profitability of the business.

Who May Require a Stock Audit?

A stock audit may be required or requested by:

• company management;
• statutory auditors;
• banks and financial institutions;
• lenders;
• investors;
• group management;
• overseas parent companies; and
• other stakeholders.

The exact purpose and scope depend upon the circumstances of the assignment.

Why is Stock Audit Important?

Inventory is susceptible to errors, damage, theft, pilferage, incorrect valuation and record-keeping discrepancies.

Periodic stock audits help management obtain greater assurance over inventory records and controls.

1. Verification of Physical Stock

One of the primary objectives of a stock audit is to determine whether inventory shown in the books actually exists.

For example:

Stock as per Books: 10,000 Units

Physical Stock: 9,650 Units

Shortage: 350 Units

The difference should be investigated to identify its reason.

Possible causes may include:

• unrecorded sales;
• unrecorded consumption;
• theft or pilferage;
• damaged stock;
• incorrect stock entries;
• measurement differences; or
• timing differences.

The existing article also identifies matching book stock with physical inventory as one of the principal reasons for conducting a stock audit.

2. Detection of Inventory Shortages and Excesses

Stock verification may identify both shortages and excess quantities.

A shortage does not automatically mean fraud.

Similarly, excess stock does not necessarily mean that the company has gained inventory.

Both situations can indicate weaknesses in:

• purchase recording;
• sales recording;
• production records;
• stock transfers;
• material consumption;
• returns;
• inventory coding; or
• cut-off procedures.

Significant discrepancies should therefore be reconciled and their root causes identified.

3. Prevention of Theft, Fraud and Pilferage

Inventory is particularly vulnerable where goods are:

• high-value;
• easily movable;
• small in size;
• stored across multiple locations; or
• subject to weak access controls.

Regular physical verification can act as an important detective and preventive control.

The existing page similarly recognises that regular inventory audits can help prevent loss, fraud and pilferage.

4. Identification of Slow-Moving and Obsolete Stock

Businesses may continue carrying inventory that has little or no commercial value.

Stock audits can help identify:

• non-moving inventory;
• slow-moving inventory;
• obsolete goods;
• damaged goods;
• expired goods; and
• scrap.

Management can then determine whether appropriate action or accounting treatment is required.

5. Correct Inventory Valuation

Physical existence alone does not establish that inventory is correctly reported in financial statements.

Inventory must also be appropriately valued under the applicable accounting framework.

The auditor may therefore examine:

• costing methodology;
• purchase cost;
• production cost;
• overhead allocation;
• net realisable value;
• damaged goods;
• obsolete goods; and
• valuation consistency.

The original article also identifies correct inventory valuation as an important purpose of stock audit.

6. Accurate Profit Determination

Inventory has a direct impact on the cost of goods sold and therefore on profit.

For a trading or manufacturing business:

Opening Stock + Purchases/Production Cost – Closing Stock = Cost of Goods Sold

If closing inventory is overstated, profit may also be overstated.

If closing inventory is understated, reported profit may be understated.

Reliable inventory records are therefore essential for accurate financial reporting.

7. Strengthening Internal Controls

A stock audit can reveal weaknesses in the organisation’s inventory-control system.

For example:

• unrestricted warehouse access;
• material issued without authorisation;
• stock transfers without documentation;
• delayed entries;
• negative inventory;
• absence of periodic reconciliation;
• weak segregation of duties; or
• inadequate review of obsolete stock.

Management can use these observations to strengthen the Internal Control System.

8. Verification of Storage Conditions

Physical verification also provides an opportunity to examine whether inventory is appropriately stored.

Auditors may observe:

• storage layout;
• identification and labelling;
• physical security;
• segregation of damaged goods;
• segregation of obsolete stock;
• fire and safety arrangements;
• stock stacking; and
• protection from deterioration.

Poor storage practices can result in financial loss even when inventory records are otherwise accurate.

9. Assurance for Management and Shareholders

Management relies upon inventory information for:

• production planning;
• purchasing;
• sales decisions;
• working-capital management;
• cash-flow forecasting; and
• profitability analysis.

A properly conducted stock audit increases confidence in the underlying inventory information.

The existing article similarly notes that stock audit can provide assurance to management and shareholders regarding inventory management and storage systems.

10. Assurance for Banks and Financial Institutions

Stock audits can also be important where inventory is hypothecated against working-capital facilities.

Banks may need assurance regarding:

• existence of stock;
• quantity;
• valuation;
• ownership;
• insurance;
• ageing;
• drawing-power calculations; and
• adequacy of security.

The existing article also identifies assurance to banks and financial institutions regarding hypothecated stock as an important purpose of stock verification.

Stock Audit Process

The scope of a stock audit should be planned based on the nature of inventory, number of locations, transaction volumes and purpose of the assignment.

Step 1 – Understand the Business and Inventory

The auditor should first understand:

• nature of business;
• type of inventory;
• warehouses;
• factories;
• inventory accounting system;
• ERP/software;
• inventory movement;
• valuation method; and
• significant inventory risks.

Proper planning is important for an effective audit. You may also refer to our Internal Audit Planning Guide.

Step 2 – Obtain Inventory Records

Relevant information may include:

• stock ledger;
• item-wise inventory;
• location-wise inventory;
• ageing report;
• purchase register;
• sales register;
• production records;
• goods receipt notes;
• material issue notes;
• stock-transfer records; and
• previous stock-audit reports.

Step 3 – Conduct Physical Verification

Inventory may be physically:

• counted;
• weighed;
• measured; or
• otherwise verified depending upon its nature.

Special attention may be given to high-value and high-risk items.

Step 4 – Perform Test Counts

The auditor may perform test counts in both directions.

Floor to Sheet: Physical stock → inventory records.

This helps test whether physically available goods are properly recorded.

Sheet to Floor: Inventory records → physical stock.

This helps test whether recorded inventory actually exists.

Step 5 – Reconcile Physical and Book Stock

Differences should be recorded and reconciled.

For example:

The auditor should obtain explanations and supporting evidence for significant differences.

Step 6 – Perform Cut-Off Testing

Cut-off testing helps determine whether purchases and sales around the verification date have been recorded in the correct accounting period.

The auditor may inspect:

• last goods receipt before year-end;
• first goods receipt after year-end;
• last dispatch before year-end; and
• first dispatch after year-end.

The existing article also specifically identifies cut-off analysis as an important inventory audit procedure.

Step 7 – Verify Goods in Transit

Goods in transit require special attention because they may not be physically available at the company’s premises on the verification date.

The auditor may review:

• invoices;
• transport documents;
• e-way bills;
• goods receipt records; and
• subsequent receipt.

Step 8 – Review Inventory Ageing

Inventory should be classified according to age and movement.

For example:

0–90 Days → 91–180 Days → 181–365 Days → More than 365 Days

Older inventory may require investigation for obsolescence or reduced realisable value.

Step 9 – Review Inventory Valuation

The auditor may review whether inventory valuation is consistent with the applicable accounting framework and company policy.

Where relevant, reference may be made to guidance issued by the Institute of Chartered Accountants of India.

Step 10 – Review Inventory Controls

The stock audit should also evaluate relevant controls, such as:

• warehouse access;
• purchase receipt;
• material issue;
• stock transfer;
• stock adjustments;
• system access;
• approval controls;
• inventory coding; and
• periodic reconciliation.

Step 11 – Discuss Audit Findings

Before finalising the report, significant differences and control weaknesses should ordinarily be discussed with responsible personnel.

Management explanations and supporting evidence should be considered.

Step 12 – Issue Stock Audit Report

The final report may include:

• scope;
• methodology;
• inventory verified;
• significant discrepancies;
• ageing observations;
• valuation issues;
• control weaknesses;
• root causes;
• risks; and
• recommendations.

Important Stock Audit Procedures

Several procedures can improve the effectiveness of a stock audit.

ABC Analysis

ABC analysis categorises inventory according to value or importance.

A Category: High-value inventory requiring greater attention.

B Category: Medium-value inventory.

C Category: Lower-value inventory.

Audit effort can then be concentrated on higher-risk items.

The existing page also identifies ABC analysis of high-value, obsolete, dead, slow-moving and scrap items as an important reason for inventory review.

Inventory Ageing Analysis

Ageing analysis helps identify stock that has remained unused or unsold for long periods.

Such inventory may require:

• management review;
• provision;
• write-down;
• disposal; or
• alternative commercial action.

High-Value Item Testing

High-value inventory generally deserves greater audit attention because even a small quantity discrepancy can create a significant financial impact.

Sample Testing

Where inventory consists of thousands of items, verifying every item may not always be practical.

The auditor may select samples based on:

• value;
• risk;
• quantity;
• movement;
• unusual characteristics; and
• random selection.

Surprise Stock Verification

Surprise verification can be useful where management considers theft, pilferage or manipulation to be a significant risk.

Because the verification date is not known in advance, opportunities for temporary adjustment of records may be reduced.

Common Issues Identified During Stock Audit

Stock audits can identify both quantity differences and broader control weaknesses.

Physical Stock Shortage

Physical quantity is lower than inventory recorded in the books.

Possible causes include theft, unrecorded consumption, recording errors or incorrect stock movements.

Physical Stock Excess

Physical quantity exceeds book records.

Possible causes include unrecorded purchases, incorrect issues, sales returns or system errors.

Negative Inventory

ERP systems may show negative quantities because of delayed or incorrect transaction posting.

Negative stock can indicate weaknesses in inventory recording and cut-off controls.

Obsolete Inventory

Inventory may remain in the books despite no longer having meaningful commercial use.

Damaged Stock

Damaged inventory may require separate identification and appropriate valuation consideration.

Stock at Third-Party Locations

Inventory stored with:

• job workers;
• consignment agents;
• warehouses;
• logistics providers; or
• other third parties

may require separate verification or confirmation.

Incorrect Inventory Coding

Duplicate or incorrect item codes can distort inventory quantities and ageing reports.

Weak Documentation

Missing goods receipt notes, stock-transfer documents or material issue records can make inventory movement difficult to verify.

Stock Audit and Internal Audit

Stock audit can form part of a broader internal audit programme.

An internal audit may examine the complete inventory cycle:

Purchase → Receipt → Storage → Production/Consumption → Transfer → Sale → Dispatch → Accounting

The auditor evaluates not merely the final stock quantity but also the controls governing inventory movement.

For further understanding, see What is Internal Audit? and our Internal Auditing Checklist.

Stock Audit and Statutory Audit

Inventory can be a significant financial statement item, particularly for manufacturing and trading businesses.

Statutory auditors may therefore need appropriate audit evidence concerning inventory depending upon its materiality and the circumstances of the audit.

A separately conducted stock audit can provide useful information, but the statutory auditor determines the audit procedures necessary for the statutory audit engagement.

Businesses can read more about our Statutory Audit Services in India.

Stock Audit for Banks and Working Capital Finance

Stock audits are commonly associated with businesses enjoying working-capital facilities secured against inventory and receivables.

Verification of Hypothecated Stock

The auditor may examine whether stock reported to the bank:

• exists;
• belongs to the borrower;
• is properly valued;
• is adequately insured; and
• is free from significant discrepancies.

Drawing Power

Depending upon the lending arrangement, drawing power may be calculated based on eligible inventory and receivables after applying prescribed margins.

Incorrect inventory information can therefore affect borrowing limits.

Identification of Obsolete Stock

Old or obsolete inventory may not provide the same security value as readily saleable inventory.

Ageing analysis therefore becomes important from a lender’s perspective.

Stock Audit for Manufacturing Companies

Manufacturing companies generally have more complex inventory flows.

Raw Materials

The auditor may examine:

• receipts;
• quality acceptance;
• storage;
• consumption;
• purchase returns; and
• closing quantities.

Work-in-Progress

WIP verification may require understanding:

• stage of production;
• quantity;
• completion percentage;
• production records; and
• valuation methodology.

Finished Goods

The auditor may verify:

• quantities;
• product codes;
• batches;
• storage;
• ageing;
• dispatch records; and
• valuation.

Stores and Spares

Stores and spares can become slow-moving or obsolete and should therefore be periodically reviewed.

Stock Audit for Foreign-Owned Companies in India

Indian subsidiaries of foreign companies may have additional inventory-control requirements because local inventory reporting may also need to comply with global group policies.

Group Reporting and Local Books

Differences can arise between:

• ERP data;
• Indian accounting records;
• physical inventory; and
• overseas group reporting.

Stock audit can help identify and reconcile these differences.

Imported Inventory

Auditors may need to understand:

• goods in transit;
• customs documentation;
• foreign-currency purchases;
• landed cost;
• import duties; and
• inventory received after the reporting date.

Related-Party Inventory Transactions

Inventory purchased from or sold to overseas group companies may require appropriate documentation and reconciliation.

For foreign-owned companies, inventory review may therefore form part of a broader Audit & Assurance engagement.

Benefits of Regular Stock Audit

A properly planned stock audit can provide several benefits.

Better Inventory Accuracy

Regular reconciliation helps keep inventory records aligned with physical quantities.

Improved Working Capital Management

Identifying excess and slow-moving stock helps management reduce unnecessary capital blocked in inventory.

Better Fraud Prevention

Regular verification increases the likelihood that shortages and unauthorised movements will be detected.

Reliable Financial Reporting

Accurate quantities and valuation improve the reliability of financial statements.

Improved Operational Controls

Stock audit findings can help management strengthen procurement, warehousing, production and dispatch controls.

Better Decision-Making

Reliable inventory information assists management in purchasing, production planning, sales and cash-flow management.

How Often Should Stock Audit Be Conducted?

There is no single frequency suitable for every organisation.

Frequency may depend upon:

• inventory value;
• transaction volume;
• nature of goods;
• risk of theft;
• number of locations;
• lender requirements;
• management requirements; and
• strength of existing controls.

Annual Verification

Annual verification may be appropriate for certain organisations and reporting requirements.

Periodic Verification

Higher-risk businesses may perform quarterly or monthly cycle counts.

Continuous Cycle Counting

Large organisations may continuously verify selected categories throughout the year rather than counting the entire inventory only once.
