Sheet Structure

The template is organized across six core sheets to ensure modular functionality and ease of navigation:

1. Inventory Master: Contains all product or item details, including SKUs, categories, suppliers, and units of measure.
2. Stock Levels: Tracks current inventory quantities across warehouses or locations in real time.
3. Demand Forecast: Uses historical data to predict future demand based on seasonality, trends, and business cycles.
4. Resource Allocation Plan: Links inventory needs to workforce, equipment, and logistics resources for efficient planning.
5. Reorder Points & Orders: Automatically calculates when reorders are needed based on safety stock and lead time.
6. Dashboard Summary: Provides visual summaries with key performance indicators (KPIs) such as inventory turnover, stockouts, and reorder frequency.

Formulas & Calculations

The template leverages built-in Excel functions and dynamic formulas for accuracy and automation:

• Forecast Demand Calculation: =Historical_Avg * (1 + Trend_Factor) * (1 + Seasonality_Adjustment)
• Reorder Point: =Safety_Stock + (Average_Daily_Usage * Lead_Time_Days)
• Order Quantity: =MAX(0, Reorder_Point - Current_Stock_Level)
• Inventory Turnover Ratio: =COGS / Average_Inventory (calculated in Dashboard)
• Stockout Risk %: =IF(Current_Stock < Reorder_Point, 1, 0) * 100%
• Days of Supply: =Current_Stock / Daily_Average_Demand (in Stock Levels sheet)

Conditional Formatting Rules

To enhance visibility and alert users to potential issues:

• Critical Low Stock (Red Highlight): When stock level < reorder point in Stock Levels.
• High Demand Alert (Orange): Forecasted demand > 120% of historical average in Demand Forecast.
• Out-of-Range Values (Yellow): If quantity exceeds max stock level or falls below min level.
• Missing Data Flag: In all sheets where a required field is blank, displays "⚠️ Missing" with red font.
