What Is an Inventory Adjustment?

An inventory adjustment is the process of correcting stock quantities or values in your system so they match the actual physical inventory. Adjustments usually happen due to damage, theft, counting errors, or valuation changes.

Why Are Inventory Adjustments Important?

Inventory adjustments keep accounting records accurate and compliant. They directly affect cost of goods sold, pricing accuracy, and financial reporting, giving management a true picture of business health.

Types of Inventory Adjustments

1. Decreasing quantity – Used when physical stock is less than recorded stock.

2. Increasing quantity – Used when physical stock is more than system stock.

3. Re-evaluation – Quantity remains the same, but item value is corrected.
