Explanation:
What is Stock Valuation?
Stock valuation is the process of determining the value of a company’s inventory at the end of an accounting period. It includes raw materials, work-in-progress, and finished goods. The valuation directly affects the cost of goods sold (COGS) and net profit on the financial statements.

Why It Matters to the Sales Department
The sales department is responsible for setting selling prices and ensuring that products are priced in a way that maintains or increases profitability. Stock valuation helps them do this by providing insight into:

- The actual cost of producing each item.

- How cost fluctuations (due to inflation or changes in suppliers) impact the minimum price at which goods should be sold.

- What pricing strategy will result in a sustainable profit margin.

- In essence, it helps avoid selling below cost or overpricing in a competitive market.


How Stock Valuation Affects Profitability
The formula for profit is:

Profit = Revenue – Cost of Goods Sold (COGS)

Since stock valuation influences the COGS, it directly affects profit:

If inventory is overvalued, COGS is understated, and profits may look inflated.

If inventory is undervalued, COGS is overstated, and profits may appear lower.

Therefore, accurate stock valuation is crucial for setting prices that truly reflect business costs and profitability.
