Table Structures and Column Definitions

All tables are structured using standardized data types and consistent naming conventions to ensure clarity and interoperability. Each sheet uses relational logic where applicable, allowing seamless cross-sheet references.

1. Product Inventory Master

The Total Value column uses a simple formula to calculate the product of unit cost and stock level.

2. Purchase History Log

The Total Cost (USD) column applies a formula: =Quantity Purchased * Unit Cost.

Formulas Required

• Total Inventory Value: =SUMPRODUCT(UnitCost, StockLevel) in the master sheet.
• Average Cost per Unit: =AVERAGEIF(Purchase History Log!Unit Cost) for a given product.
• Monthly Expenditure Forecast: Uses moving averages based on past 6 months of purchase data in the Purchase History sheet.
• Inventory Turnover Ratio: =Cost of Goods Sold / Average Inventory (calculated via VLOOKUP and SUMIFS).
• Stock Level Alerts: Uses IF statements to flag low stock: IF(StockLevel < ReorderPoint, "Low", "")
• Cumulative Cost Tracking: Uses SUMIFS to track total cost by category and time period.

Conditional Formatting Rules

This template applies dynamic conditional formatting to highlight critical cost trends:

• Red Highlight: When Total Value exceeds 90% of the monthly budget limit (in the Dashboard).
• Yellow Highlight: If stock levels are below reorder thresholds.
• Green Background: For products with a cost variance < 5% from average.
• Critical Warning: Applies to any product whose unit cost has increased by more than 10% over the last 6 months (based on historical purchase data).

User Instructions

Users are advised to follow these steps for effective implementation:

1. Enter product details and initial stock in the Product Inventory Master sheet.
2. Add all purchase transactions with accurate dates, quantities, and unit prices in the Purchase History Log.
3. Set reorder thresholds by updating values in the Reorder Alerts & Thresholds sheet (e.g., 50 units for critical items).
4. Each month, run the dashboard to review cost control metrics and identify areas of over-investment.
5. Update cost values whenever price changes occur due to supplier negotiations or market shifts.
