Inventory Write Off – Definition & Impact

Inventory write off definition

An inventory write off occurs when an inventory item is removed from the company’s accounting records because the item is no longer considered to have value.

The reasons for the removal can include:

• damaged goods
• missing items
• obsolescence
• malfunctioning items that don’t meet QA specifications

In short, that material or finished good is no longer able to help production or sales.

Oracle NetSuite that explains “when inventory value is totally eliminated, that loss is recorded in the contra account or cost of goods sold (COGS) accounting, depending on the significance of the write-off.”

Inventory write off summary

Inventory write offs have a direct impact on the way companies report their cost of goods sold (COGS) and the accuracy of the financial reports. That said, write-offs are rarely a simple accounting event. They often indicate deeper manufacturing problems like:

• excess stock
• inaccurate forecasting
• product lifecycle misalignment
• operational breakdowns.

Companies can however reduce write-offs by detecting the conditions that caused them and reacting as early as possible. To do so they look for the following:

• ERP (Enterprise Resource Planning) – inventory levels remaining high while sales orders or consumption rates decline, indicate excess or slow-moving stock.
• MES (Manufacturing Execution System) – scrap rates, defect rates, or rework levels increasing, indicate that produced inventory may become unusable
• APS (Advanced Planning and Scheduling System) – forecast demand drops or shifts while production plans remain unchanged, creating a mismatch that leads to overproduction and obsolescence.

Uncontrolled inventory write off risks.

There are several ways in which write-offs create multiple operational and financial risks in manufacturing environments:

• Inaccurate financial reporting – Inventory remains overstated, therefore balance sheet and profit/loss will also be distorted. As a result, executive and investor decisions will be made based on incorrect information.
• Buildup of excess and obsolete inventory – Poor demand planning and/or disconnected systems can lead to over-production. If inventory does not match actual demand, write-offs will rise as products expire or lose relevance.
• Production planning breakdown – Planning and scheduling systems (APS & ERP) depend on accurate inventory. Unusable inventory should be written off. If not, the systems will assume that materials are available, resulting in delays or shortages during production.
• Quality and handling failures – Damage to items typically indicates issues related to manufacturing execution, such as variability in processing or inadequate storage of items. Write offs will then be symptomatic of the problem, rather than addressing the root cause.
• Cash flow constraints – Cash tied-up in unused inventory means reduced liquidity. This limits the ability of a company to invest in raw materials, equipment or process improvements.

5 Benefits of effective inventory write off management

There are 5 main benefits to managing inventory write offs effectively:

1. Accurate financial reporting – Write offs done on a timely basis allow financial statements to accurately represent the value of assets. Improved decision making and improved compliance with GAAP and IFRS reporting standards are a direct result.
2. Improved demand and supply alignment – By identifying obsolete or excess inventory early in the process, manufacturers can adjust forecasts and production schedules. This results in more reliability of ERP and APS systems as inputs for planning.
3. Better production efficiency – Removing unused inventory will prevent false availability signals. Production teams will be able to rely on correct data and eliminate downtime and scheduling conflicts.
4. Root cause identification – Tracking write offs allows for the isolation of issues including, but not limited to, poor forecasting, supplier variability or process defects. Data from MES can be used to determine where in the production process the defect occurred and what conditions existed.
5. Optimized working capital – Reducing unnecessary inventory frees up cash. This enables reinvestment into higher-value activities such as new product development or capacity expansion.

6 step inventory write off process

Here is an inventory write off process sequence that helps manufacturers achieve accuracy, traceability, and compliance.

1. Log unusable inventory

Inventory is identified as unusable due to cycle count, quality inspection, or system alert. The most frequent causes of unusable inventory are damage, expiration, and/or obsolescence, due to fluctuations in customer demand.

2. Verify and conduct root cause analysis

The team confirms that the inventory is unusable. Teams also review MES and quality data to identify if the problem occurred at the production, warehousing, or external stages.

3. Assess the valuation

The finance teams assess the dollar amount associated with the write off. This entails determining the book value of the inventory and whether a full or partial write off is necessary.

4. Approval and documentation

Prior to making the necessary adjustments to the accounting records, internal controls require official approval. A workflow within ERP system usually automates the approval process, ensuring compliance and a clean audit trail.

5. Accounting entry

The inventory is removed from the accounting records, and the corresponding expense is recognized. This step updates both operational inventory levels and financial statements.

Step 6: Continuous Improvement

Any insight gained from the write-off is fed back into the planning and execution processes. Examples of potential changes include updated forecasting models, alternative suppliers, and process improvements.

Inventory Write Off FAQ

Inventory Write Off vs. Inventory Write-Down

Inventory write offs and write-downs are commonly confused; however, they represent two different types of losses in inventory value.

An inventory write off is the removal of inventory completely from all records because the inventory has no residual value.

An inventory write-down is the reduction in value of inventory that can still be sold; the sale price is usually below the original purchase price.

Write-downs are typical in industries that have volatile prices whereas write-offs are specific to inventory that is unusable.

Inventory Write Off vs. Scrap

Scrap is defined as the physical material that is unable to be produced into the intended product(s) due to defects and/or poor quality.

Inventory write off represents the financial acknowledgment of that loss.

MES systems track scrap at the manufacturing level while ERP systems formally document the write off in the company’s accounting system.

Inventory Write Off vs. Obsolescence

Obsolescence is defined as a condition where inventory is no longer needed due to the need for a new product or service.

An inventory write off is the method by which the company acknowledges that their inventory is no longer useful.

Demand planning and lifecycle management are two tools used to prevent obsolescence from resulting in an unnecessary write off.
