Sheet Names and Structure

1. Inventory Master: Central database of all products, including SKUs, categories, units, and suppliers.

5. Dashboard Summary: A visual overview of key metrics such as stock turnover rate, low-stock alerts, total value on hand, and top-selling items.

Table Structures and Data Types

Formulas Required

• Stock Balance Calculation: In the "Stock Levels & Movement" sheet, use: `=SUMIFS(Quantity, Type, "Purchase") - SUMIFS(Quantity, Type, "Sale")` to calculate net stock.
• Reorder Alerts: Use `=IF(Balance < Reorder Level, "⚠️ Low Stock", "")` in the Inventory Master sheet to flag items needing restocking.
• Monthly Revenue Summary: In Sales & Orders, use `=SUMIFS(Total Amount, Status, "Completed", Date, ">=DATE(2024,1,1)")` to calculate monthly income.
• Inventory Turnover Rate: Use `=Total Cost of Goods Sold / Average Inventory Value` (calculated across periods) to evaluate efficiency.
• Automated Supplier Evaluation Score: Calculate a weighted score based on lead time, delivery accuracy, and order fulfillment rate using: `=0.4*(On-Time Rate) + 0.3*(Lead Time Score) + 0.3*(Response Time)`.

Conditional Formatting Rules

• Low Stock Flagging: Highlight cells in the "Inventory Master" sheet where stock level is below reorder point using a red background with bold text.
• Sales Performance: In the Sales & Orders sheet, highlight top 5 selling products in green; underperformers in yellow.
• Out-of-Stock Warnings: Flag any product with zero stock (using `=IF(Balance=0, "⚠️ Out of Stock", "")`) with a red border and warning icon.
• Supplier Risk Score: Apply color gradients to supplier performance scores: green (≥90%), yellow (75–89%), red (<75%).
