Inventory Write-Offs: How to Do Them Properly and What They're Telling You
Every business that carries physical inventory will eventually write some of it off. Products expire. Goods get damaged. Markets move on and leave products obsolete. This is a normal cost of doing business.
What's not normal — or at least shouldn't be — is write-offs that happen because of process failures: poor ordering decisions, inadequate storage, no expiry management, inadequate receiving checks.
Understanding how to do a write-off correctly, and how to read write-off patterns, gives you both cleaner books and better operational intelligence.
Write-Down vs. Write-Off: The Accounting Distinction
These terms are used interchangeably in conversation but have different technical meanings.
Write-down: You reduce the carrying value of inventory from its original cost to a lower value — typically its net realizable value (what you can actually sell it for). The inventory still exists; it's just worth less than you originally recorded.
Example: You bought 100 units at Rs. 200. The market price has dropped and you can only realistically sell them for Rs. 120. You write the inventory down to Rs. 120/unit. The reduction (Rs. 80/unit × 100 units = Rs. 8,000) is recognized as a loss.
Write-off: You remove the inventory from your books entirely — its value goes to zero. This is used when the inventory has no recoverable value: it's expired, destroyed, unsellable, or has been confirmed missing.
Example: 50 units of a product have passed their expiry date and cannot be sold or donated. You write them off: Rs. 200/unit × 50 units = Rs. 10,000 removed from inventory and recognized as a loss.
When to Write Off Inventory
Expiry or obsolescence: Products past their sell-by or expiry date. Products that have been superseded by newer versions and can't be sold.
Damage: Goods damaged in storage, transit, or handling to the point they can't be sold. This should be documented with photographs and damage assessment.
Confirmed missing: When a cycle count or stocktake confirms that inventory shown in the system doesn't exist. If it can't be located after investigation, it needs to be written off.
Quality failure: Products that fail quality inspection after production or receiving, with no path to rework or return.
Theft confirmed: When investigation confirms that shrinkage was the result of theft and the quantity can't be recovered.
The Accounting Entry
When you write off inventory, the accounting treatment is:
Dr. Loss on Inventory Write-Off (expense — hits your P&L) Cr. Inventory (asset — reduces your balance sheet)
The loss flows through your income statement as an operating expense. It reduces your gross profit.
For a write-down (not a full write-off):
Dr. Inventory Impairment Loss (expense) Cr. Inventory (reduced to net realizable value)
Your accounting software should handle this automatically when you record a write-off or write-down transaction — crediting the inventory account and debiting the appropriate expense account based on the reason code.
VAT Considerations
In Nepal and most VAT jurisdictions, when you claim input VAT on goods you purchased, you're expected to have sold those goods (generating output VAT). Goods that are written off — particularly if they're destroyed — may trigger a requirement to reverse the input VAT you originally claimed.
The specific rules vary by jurisdiction and product category. Consult your tax advisor about write-off VAT treatment in Nepal — particularly for larger write-offs.
The Process: How to Execute a Write-Off Properly
Step 1: Identify and document. What's being written off, why, quantity, and cost value. Photographic documentation for damaged goods. Count records for missing inventory.
Step 2: Get approval. Inventory write-offs above a defined threshold should require management approval before processing. This is a financial control that prevents unauthorized removal of inventory value. Your approval workflow should include write-off authorization.
Step 3: Record in the system. Create the write-off transaction with the correct reason code, quantity, and value. The inventory record is reduced, and the accounting entry is created.
Step 4: Physical disposal (if applicable). Expired or dangerous goods need appropriate disposal. Keep disposal records — particularly for products subject to regulatory requirements.
Step 5: File the supporting documentation. The write-off record should be linked to the supporting documentation (damage report, count record, disposal confirmation). This creates the audit trail.
What Write-Off Patterns Tell You About Operations
Here's where write-offs become operationally useful rather than just an accounting exercise.
High write-offs on expired goods → Your expiry management is weak. You're not tracking expiry dates or not dispatching FEFO. See batch and lot tracking for how to fix this.
High write-offs on damaged goods → Storage conditions, handling procedures, or packaging have a problem. Investigate where damage is occurring in the supply chain.
High write-offs on obsolete goods → Demand forecasting is failing, or buying decisions aren't being challenged enough. Products are being bought in quantities that exceed demand, or held too long without a clearance process. Dead stock management needs attention.
Write-offs concentrated in specific locations or categories → A specific warehouse zone, product category, or handling process has a problem worth investigating.
Write-offs with no clear reason → Your investigation process before write-off is inadequate. "Unknown" or "adjustment" as write-off reasons is a red flag — it may indicate that discrepancies are being cleared with a write-off instead of understood.
If you're doing significant write-offs regularly, you have a process problem — not an inventory problem. The write-offs are the symptom; the root cause is almost always in procurement, storage, handling, or inventory accuracy management.
The Financial Statement Impact
Write-offs reduce inventory (asset) and increase operating expenses (reducing profit). For businesses with significant inventory on the balance sheet, a large write-off can have material impact on:
- Gross margin (lower, due to higher COGS or impairment loss)
- Balance sheet inventory value (lower, which may affect borrowing calculations if inventory is used as collateral)
- Tax position (write-offs reduce taxable income, which may be a planning consideration)
For businesses approaching financial close, a complete write-off review should be part of the pre-close process — not left to year-end when the write-offs have been accumulating all year.
