How to Record a Provision for Inventory Obsolescence Using an Allowance Account
Creating a reserve for stock unlikely to be sold due to damage, expiry, or lack of demand, using the prudence principle.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Inventory Obsolescence Expense | Expense (+) | 3,000.00 | - |
| Allowance for Obsolescence | Contra-Asset (+) | - | 3,000.00 |
💡 Accountant's Note
This follows the Prudence principle. Instead of reducing inventory directly, we create a 'bucket' (allowance) to show the estimated loss in value.
Practitioner & Systems Framework
💻 ERP Architecture
Set up an Allowance for Obsolescence contra-asset account in the ERP linked to the Merchandise Inventory account. Run a monthly slow-moving inventory report segmented by days-since-last-sale (0–90, 91–180, 181–365, 365+) and apply tiered provision rates (e.g., 10%, 25%, 50%, 100%). The ERP should update the allowance balance each period based on the current aging — it is a point-in-time estimate, not a cumulative addition.
⚠️ Audit Flags
Auditors test provision rates against historical actual write-offs to confirm they are reasonable and not systematically understated to inflate inventory values. Watch for management overrides that reduce the provision near year-end. A provision methodology that hasn't changed in years despite rising slow-moving balances signals stale estimates.
📄 Required Documentation
Inventory aging report by SKU, provision methodology memo (aging bands and rates), prior-period comparison showing actual vs. estimated write-offs, management sign-off on the provision calculation, and year-end balance reconciliation to the sub-ledger.
