Formulas Required

The template utilizes powerful Excel formulas to automate calculations:

• =SUMIFS(Stock Movement Log!D4:D1000, Stock Movement Log!C4:C1000, A2, Stock Movement Log!B4:B1000, "Sale"): Calculates total quantity sold for a product.
• =SUMPRODUCT(Purchase History!C3:C50, Purchase History!D3:D50): Computes total cost of purchases (with dynamic array).
• =IF(Stock Level < Reorder Point, "Reorder Needed", "OK"): Flags low stock automatically.
• =C2 - D2 (in Stock Movement Log): Calculates new stock level after transaction.
• =VLOOKUP(A2, Product Inventory Master!A:B, 2, FALSE): Fetches product description from master table.
• Dynamic Range References: Using named ranges for ease of update and formula management.

Conditional Formatting

The template applies conditional formatting to highlight key cost control issues:

• Red fill when inventory falls below reorder point in the Product Inventory Master.
• Yellow highlight when total purchase cost exceeds 10% of projected quarterly budget.
• Green background for products with cost variance under 5%.
• Fade animation on stock levels that have changed in the last week (to indicate volatility).
• Data bars in the Cost Variance Analysis to show deviation magnitude visually.
