Writing Off Inventory at Market Cost or Less: A Guide for Small Business Owners

June 19, 2025 - 6 minutes read

For small business owners and inventory managers, managing inventory effectively is critical to keeping costs under control and ensuring profitability. However, there are times when inventory doesn’t sell as expected. Whether it’s due to damaged goods, shifts in consumer demand, or product obsolescence, knowing how to handle excess inventory is essential. One way to manage unsold inventory is through an inventory write-off.

What Is an Inventory Write-Off?

An inventory write-off is an accounting process used to remove unsellable or excess inventory from a company’s books. When an item’s value drops below its original cost (due to damage, market trends, or spoilage), a write-off adjusts the financial records to reflect this loss.

It’s a practical way to ensure your business’s financial statements stay accurate while reducing unnecessary carrying costs.

When Should You Write Off Inventory?

Businesses should consider writing off inventory under the following situations:

  • Damaged Goods: Products that are broken or unsellable due to manufacturing defects or mishandling.
  • Perishable Inventory: Items like food, beverages, or medicine that have expired or spoiled.
  • Obsolete Products: Goods that have lost consumer demand due to changes in industry trends, seasonal fluctuations, or new product releases.
  • Excess Stock: Overproduction or over-ordering that leads to unsold items.

If the estimated market value—including the potential cost of selling—is less than your book value, writing it off is often the best course of action.

The Process of Writing Off Inventory at or Below Market Cost

1. Evaluate Your Inventory

Start by conducting a thorough inventory audit. Identify products that are damaged, perishable, or obsolete. Assess their current market value, considering factors such as age, demand, and condition.

2. Determine the Write-Off Value

Calculate the new market value or recoverable amount of the inventory. If this amount is lower than the original book value, record the difference as a loss.

For example, if your inventory’s book value is $10,000 but the market value drops to $7,000, the $3,000 difference is recorded as a write-off.

3. Record the Entry in Your Books

To document the inventory write-off, use the following journal entry in your accounting software:

  • Debit the Cost of Goods Sold (COGS) or a designated “Loss on Inventory Write-Off” account.
  • Credit the Inventory Account to reflect the reduced stock value.

4. Review Tax Implications

Inventory write-offs can reduce your taxable income, providing a financial benefit to your business. Keep detailed documentation to justify the write-off in case of an audit, and consult with a tax professional or accountant to ensure compliance with local regulations.

5. Leverage Inventory Insights

Use insights from the write-off process to improve future inventory decisions. Address issues like over-ordering or stocking slow-moving products to prevent similar losses.

Here’s what one of our clients, a local boutique owner, had to say about implementing this approach:

“After learning about inventory write-offs, I was able to clear old stock and free up valuable storage space. It also helped me pinpoint which styles were underperforming, so I could make smarter buying decisions moving forward.”

Benefits of Writing Off Inventory

  • Accurate Financial Records

Writing off inventory ensures your financial statements reflect the true value of your assets. This transparency strengthens your position when applying for loans or seeking investors.

  • Reduced Storage Costs

Obsolete or unsellable inventory often takes up valuable storage space. Writing it off allows you to clear stock and focus on more profitable items.

  • Optimized Future Purchases

Analyzing write-offs helps highlight areas for improvement in your inventory management system, enabling smarter purchasing decisions that align with customer demand.

  • Tax Savings

Inventory write-offs may qualify as a deductible business expense, reducing your overall tax liability.

Preventing Inventory Write-Offs

While write-offs are sometimes inevitable, proactive planning can minimize their occurrence. Here are a few steps to maintain better inventory control:

  • Implement an Inventory Management System that provides real-time insights into stock levels and demand trends.
  • Adopt First-in, First-out (FIFO) practices to ensure older inventory gets sold before newer stock.
  • Forecast Demand Accurately by analyzing sales data and industry trends.
  • Offer Promotions or Discounts to clear slow-moving inventory before its market value declines.

Wrapping Up

Inventory write-offs are a crucial part of managing a business’s financial health. By understanding when and how to write off inventory valued at or below market cost, small businesses and inventory managers can protect their bottom line while maintaining clean, accurate financial records.
