Statutory Audit of a Manufacturing Company — Key Focus Areas and Checklist 2026

Introduction

A statutory audit of a manufacturing company is not simply about checking whether the figures in the financial statements add up. The real challenge is understanding how those numbers are generated—from procurement of raw materials to production, inventory movement, sales and ultimately the financial statements.

For auditors in 2026, manufacturing audits require a closer look at inventory controls, fixed assets, production records, statutory compliance, related-party transactions, borrowings and the reliability of accounting systems. The objective is not only to identify errors but also to determine whether the financial statements present a true and fair view of the company’s financial position.

Key Focus Areas

1. Inventory and Stock

Inventory is generally one of the most sensitive areas in a manufacturing audit. Auditors should verify:

Physical stock verification and reconciliation with books

Raw materials, work-in-progress and finished goods

Slow-moving and obsolete inventory

Valuation of inventory as per the applicable accounting framework

Consumption of raw materials against production

Stock transfers between locations

Goods lying with third parties

Cut-off for purchases, production and sales

A difference between physical stock and the books should never be treated as a routine reconciliation issue without understanding its underlying reason.

2. Property, Plant and Equipment

Manufacturing businesses generally have significant investments in plant and machinery. The audit should cover:

Additions and supporting purchase invoices

Capitalisation of expenditure

CWIP and ageing of pending projects

Physical verification of major assets

Depreciation and useful lives

Disposals and scrapping of machinery

Repairs and maintenance incorrectly capitalised as assets

CARO 2020 also contains specific reporting requirements relating to property, plant and equipment and intangible assets.

3. Production and Cost Records

The auditor should understand the production cycle rather than relying only on the accounting ledger.

Key checks include:

Raw material consumption

Production quantities

Normal and abnormal wastage

Production yield

Labour and manufacturing overheads

Power and fuel consumption

Job work

Process loss

Costing of finished goods and WIP

Where the company falls within the prescribed classes, the applicability and maintenance of cost records under Section 148 should also be examined.

4. Revenue and Sales Cut-off

Revenue should be tested from both accounting and operational perspectives.

Auditors should reconcile:

Sales Register → GST Returns → E-Invoices/E-Way Bills → Dispatch Records → General Ledger

Particular attention should be given to:

Sales recorded near year-end

Goods dispatched but not invoiced

Invoices raised but goods not dispatched

Sales returns and credit notes

Export sales

Discounts and rebates

Related-party sales

A mismatch between books and GST/statutory records can be an important audit red flag. ICAI’s recent disciplinary updates also demonstrate the importance of not relying blindly on management records where material discrepancies exist.

5. Purchases and Trade Payables

The auditor should verify whether purchases are genuine, properly recorded and supported.

Important procedures include:

Vendor master review

Purchase invoice verification

GRN matching

Three-way matching of PO, GRN and invoice

Vendor balances and confirmations

Unrecorded liabilities

Purchases around year-end

Debit balances in trade payables

Related-party vendors

6. Statutory Dues and Compliance

Manufacturing companies normally have multiple statutory obligations. The audit should cover applicable:

GST

TDS/TCS

Provident Fund and ESI

Income tax

Professional tax

Labour-related dues

Customs duties

Other applicable statutory liabilities

The focus should not be limited to whether a liability appears in the ledger. The auditor should also examine whether the liability was correctly calculated, paid on time and reconciled with statutory returns.

7. Borrowings and Working Capital

Manufacturing businesses often have substantial working-capital facilities.

Key areas include:

Bank reconciliations

Cash-credit/OD accounts

Stock statements submitted to banks

Drawing power calculations

Term loans

Interest calculations

Security and charges

Loan covenants

Utilisation of borrowed funds

The figures reported to banks should be compared with the underlying accounting records wherever relevant.

8. Related-Party Transactions

Review:

Directors and relatives

Group companies

Common vendors/customers

Loans and advances

Purchases and sales

Rent and service arrangements

Management remuneration

The auditor should ensure that transactions are properly authorised, recorded and disclosed as required.

9. Internal Financial Controls

Manufacturing companies depend heavily on controls over:

Purchase → Stores → Production → Inventory → Sales → Collection

Weak controls at any stage can directly affect the financial statements.

The auditor should assess controls over authorisation, segregation of duties, inventory movement, purchase approvals, sales invoicing and system access.

10. Accounting Software and Audit Trail

The audit should also consider whether the accounting system maintains an appropriate audit trail and whether changes to accounting records can be identified.

For financial years commencing on or after 1 April 2022, auditors have reporting responsibilities relating to the audit trail under Rule 11(g).

Practical Manufacturing Audit Checklist

Review internal controls and process flow

Verify physical inventory and reconcile differences

Test inventory valuation and provisions for obsolete stock

Verify additions and disposals of fixed assets

Review CWIP and capitalisation

Test purchases and vendor balances

Test sales and year-end cut-off

Reconcile GST returns with books

Review statutory dues and outstanding liabilities

Verify bank balances, borrowings and interest

Review related-party transactions

Check provisions and contingent liabilities

Review production records and cost information

Check applicable CARO 2020 clauses

Verify audit-trail compliance

Review subsequent events

Obtain management representations

Ensure appropriate disclosures in the financial statements

Conclusion

A good manufacturing audit goes beyond ticking documents against ledger balances. The auditor needs to understand the business cycle and connect physical operations with financial information.

The most effective approach is to identify the areas where a manufacturing company’s numbers can realistically go wrong—inventory, production costs, fixed assets, revenue cut-off, statutory dues and working capital—and then design audit procedures around those risks.

In 2026, the expectation from a statutory audit is increasingly clear: do not just verify the numbers; understand how the numbers were created.
