Stock Audit Red Flags: What Chartered Accountants Look For in Inventory Records

Your CA calls. "The auditor flagged some discrepancies in your inventory valuation. We need to discuss."

Your stomach drops. What discrepancies? You've been running this business for 15 years. You know your stock.

Except you don't. Not the way an auditor does. What feels normal to you looks like a red flag to them.

That conversation could go two ways: simple clarification, or weeks of document requests, questions, and potential adjustments that hit your P&L.

The difference is usually preparation, not innocence.

Why Stock Audits Matter More Now

Inventory audits have intensified for three reasons:

1. GST Cross-Verification

Pre-GST, inventory records lived in isolation. Now they connect to:

• Purchase invoices (GSTR-2A)
• Sales invoices (GSTR-1)
• E-way bills (movement tracking)
• Stock transfers (between branches)

Mismatch between your physical stock, your books, and GST filings creates automatic flags.

2. Bank Scrutiny on Working Capital

If you have inventory-backed credit, your bank cares deeply about stock accuracy. Their valuation of your assets depends on your inventory.

False or inflated inventory that secures credit is fraud. Banks and their auditors know the patterns.

3. Tax Authority Focus

Income tax scrutiny on inventory has increased. Specifically:

• Unexplained stock increases (where did it come from?)
• Suspicious write-offs (tax planning or actual losses?)
• Year-end inventory manipulation (profit smoothing)

The 12 Red Flags Auditors Are Trained to Spot

1. Perfect Round Numbers

What they see: Closing stock of exactly ₹50,00,000. Or exactly 1,000 units of every product.

Why it's suspicious: Real inventory almost never ends in round numbers. Round numbers suggest estimation, not counting.

What they do: Request physical count, sampling of high-value items, verification of counting methodology.

How to avoid: Actual physical counts produce non-round numbers. If your counts come out round, that's actually suspicious - recount.

2. Significant Year-End Inventory Movement

What they see: Massive purchases in March. Or huge write-offs in the last week of the financial year.

Why it's suspicious: Classic profit manipulation pattern. Buy more to inflate assets and defer expenses. Or write off to create losses.

What they do: Compare year-end inventory to monthly averages. Ask for documentation of unusual movements.

How to avoid: If legitimate reasons exist (seasonal stocking, discovered obsolescence), document them contemporaneously - not during audit.

3. Inventory Growth Exceeding Sales Growth

What they see: Sales up 10%, inventory up 40%.

Why it's suspicious: Why are you holding more stock relative to sales? Either you're overbuying, inflating values, or recording purchases that didn't happen.

What they do: Compare inventory turnover ratios year-over-year. Analyze by category. Ask about business justification.

How to avoid: If genuine (anticipating growth, supplier deal, bulk purchase), document the business rationale at the time of decision.

4. No Shrinkage or Write-Offs

What they see: Zero inventory losses for the entire year.

Why it's suspicious: Every business has some shrinkage - damage, theft, obsolescence, expiry. Zero losses suggests you're not monitoring or not reporting.

What they do: Sample physical counts, especially of perishables or high-theft items. Ask about your loss tracking process.

How to avoid: Track and record actual losses. A realistic shrinkage rate (1-3% depending on industry) is expected and acceptable.

5. Gross Margin Fluctuations Without Explanation

What they see: Gross margin jumps from 22% to 28% in one quarter, then back to 23%.

Why it's suspicious: Suggests possible inventory valuation manipulation. Undervalue inventory = higher COGS = lower profit. Then reverse.

What they do: Deep dive into that quarter. Check for valuation method changes, unusual write-offs or write-backs.

How to avoid: Consistent valuation methods. Document any changes and their rationale before year-end.

6. FIFO/LIFO Inconsistencies

What they see: Valuation method changes between periods. Or different methods for different products without logical basis.

Why it's suspicious: Method shopping for tax advantage. FIFO in inflationary times shows lower profit, LIFO shows higher.

What they do: Check consistency with prior years. Request documentation of method selection rationale.

How to avoid: Pick a method, document it, stick with it. Changes need solid business justification.

7. Negative Inventory Balances (Even Temporary)

What they see: System shows -47 units of a product at some point during the year.

Why it's suspicious: Means you sold more than you recorded buying. Either purchases are unrecorded (black money?) or sales were backdated.

What they do: Investigate the specific items. Trace transactions around the negative period.

How to avoid: Real-time inventory systems that prevent billing without stock. If temporary negatives happen, fix them immediately and document why.

8. Intercompany/Related Party Inventory Transfers

What they see: Large stock transfers between your business and related entities, especially near year-end.

Why it's suspicious: Profit shifting. Moving inventory to loss-making entity to balance books.

What they do: Verify transfers at arm's length prices. Check if goods actually moved. Look for round-trip transactions.

How to avoid: Document transfers with proper invoices, delivery challans, and business purpose. Price at market rates.

9. Old Inventory Not Written Down

What they see: Items sitting in inventory for 2-3 years at original purchase value.

Why it's suspicious: Old inventory loses value. Not writing it down inflates assets and understates losses.

What they do: Age analysis of inventory. Request explanation for old items still at full value.

How to avoid: Regular aging analysis. Write down slow-moving/obsolete items progressively, not in one big year-end adjustment.

10. Purchase Invoice Clustering

What they see: 40% of annual purchases from new vendors, all in March.

Why it's suspicious: Could be false purchases to inflate inventory. Or genuine purchases being pushed to year-end for cash flow reasons (but then why new vendors?).

What they do: Vendor verification. Payment trail check. Physical verification that goods exist.

How to avoid: If genuine purchases, document why (new supplier relationship, bulk deal). If not genuine... don't do it.

11. Inventory Without Supplier Invoices

What they see: Physical stock present, but no clear paper trail for how it got there.

Why it's suspicious: Unrecorded purchases = black money transactions. Or stock recorded at wrong values.

What they do: Request invoices for each category. Cross-verify with bank/payment records.

How to avoid: No purchase without proper invoice. Period. Even cash purchases need documentation.

12. Count Dates Far From Period End

What they see: Physical count done on March 15, year-end is March 31.

Why it's suspicious: Roll-forward calculations can be manipulated. Actual position on March 31 is unknown.

What they do: Ask for reconciliation of movement between count date and year-end. May request recount.

How to avoid: Count as close to year-end as practical. If gap exists, meticulously document all movement in between.

What Actually Happens During a Stock Audit

Phase 1: Planning

Auditor reviews:

• Prior year inventory records
• Accounting policies
• Known issues from last audit
• GST filings and apparent mismatches
• Industry-specific risk factors

They arrive with areas of focus already identified.

Phase 2: Physical Verification

Options:

• Full count observation (small inventories)
• Test counts (large inventories)
• Statistical sampling (very large)

What they're checking:

• Does physical quantity match books?
• Is counting methodology sound?
• Are items properly labeled/identifiable?
• Are damaged/obsolete items segregated?

Phase 3: Valuation Review

Checking:

• Cost determination method
• Market value comparison (lower of cost or NRV)
• Overhead allocation (for manufactured goods)
• Foreign exchange treatment (for imports)

Phase 4: Cut-off Testing

Critical area. Verifying:

• Goods received before year-end are included in inventory
• Goods shipped before year-end are excluded
• No double-counting between inventory and COGS
• Purchase invoices match goods receipt dates

Phase 5: Documentation Review

Connecting:

• Physical count → Inventory records
• Inventory records → Purchase invoices
• Purchase invoices → Vendor payments
• Everything → GST returns

When Auditors Ask Questions

The Right Way to Respond

Be prepared: Have documents ready. Fumbling for papers suggests disorganization or avoidance.

Be specific: "We wrote down ₹2.3 lakhs of obsolete items in November based on this aging analysis" beats "Yeah, we do write-offs sometimes."

Be honest: If you don't know, say so. "I'll need to check that and get back to you" is better than guessing wrong.

Be proactive: If you know of an issue, raise it first. Auditors respect transparency.

The Wrong Way to Respond

Defensive: "We've always done it this way" doesn't address whether it's correct.

Vague: "Stock is somewhere around that number" doesn't inspire confidence.

Evasive: "I'll have my assistant look into that" for the fifth time suggests avoidance.

Combative: Arguing with auditors rarely helps. You can disagree professionally, but fighting damages the relationship.

Red Flags You Can Fix Before They're Red Flags

Round Numbers

• Do actual counts
• Record precise figures
• If naturally round, document why

Year-End Spikes

• Spread purchases through the year
• If year-end deals are genuine, document in advance
• Keep contemporaneous records of business decisions

No Shrinkage

• Track actual losses monthly
• Create write-off register
• Realistic shrinkage is expected

Old Inventory

• Quarterly aging analysis
• Progressive write-downs
• Document obsolescence decisions

Valuation Inconsistency

• Written valuation policy
• Consistent application
• Changes documented with rationale

The Technology Angle

Audit-ready inventory systems provide:

Real-time accuracy:

• No gaps between physical and book
• Every movement logged
• Automatic reconciliation

Audit trails:

• Who changed what, when
• Original values preserved
• Cannot be backdated

Report generation:

• Aging analysis on demand
• Valuation by method
• Variance reports

Cut-off documentation:

• Timestamped transactions
• GRN-invoice matching
• In-transit tracking

A retail client implemented proper inventory software before their audit. Auditor spent 2 days on inventory instead of the planned 5. Comment in audit report: "Inventory records well-maintained with clear audit trail."

That comment builds credibility for future audits. Auditors remember smooth processes.

The Bottom Line

Auditors aren't trying to catch you doing something wrong. They're trying to verify that what you've reported is accurate.

The businesses that struggle with stock audits aren't necessarily dishonest. They're disorganized. They don't track properly. They don't document decisions. They don't prepare.

Every red flag in this article is something you can address before the auditor ever arrives. Accurate counts. Consistent methods. Contemporaneous documentation. Honest shrinkage reporting.

Do these things throughout the year, not just in March, and stock audits become verification exercises rather than investigations.
