The Top 10 Inventory Valuation Mistakes
1. Inconsistent Valuation Methods: The Foundation-Shaking Error
The Problem in Detail
Inconsistent application of inventory valuation methods represents one of the most damaging yet subtle errors businesses make. This occurs when companies inadvertently switch between FIFO, LIFO, or weighted average methods across different periods, product categories, or business locations without proper documentation or justification.

Product Category | Q1 Method | Q2 Method | Q3 Method | Impact |
---|---|---|---|---|
Main Products | FIFO | FIFO | FIFO | ✓ Consistent |
Accessories | FIFO | Weighted Avg | LIFO | ⚠ Inconsistent |
Real-World Example: MidWest Electronics
MidWest Electronics, a $4.2 million distributor, unknowingly used FIFO for their main product line while applying weighted average to accessories. This inconsistency occurred due to a system upgrade that changed default settings.
