Table Structures and Data Organization

The core of the template is structured around interlinked tables across multiple sheets, ensuring data integrity and automation.

Sheet 1: Planning View (Main Dashboard)

This sheet serves as the executive summary. It features a consolidated table showing:

• Product ID
• Product Name
• Forecasted Sales (Monthly, Quarterly)
• Current Inventory Level
• Safety Stock Level (calculated)
• Reorder Point Potential Stockout Risk (Auto-flagged)

Sheet 2: Sales Forecasting Model

This sheet contains the analytical engine for demand prediction. It includes:

Sheet 3: Inventory Tracking & Replenishment

This sheet manages real-time inventory status and automates reorder triggers.

Sheet 4: Historical Data (Raw Inputs)

A centralized database for past performance. Used as the foundation for forecasting.

Formulas Required

• Forecasted Sales Volume: =FORECAST.LINEAR(B2, $C$2:$C$13, $B$2:$B$13) × D2 × E2 (adjusts for seasonality and trend)
• Safety Stock: =STDEV.P(INDIRECT("Sales Forecasting Model!C:C")) × 1.645 (95% service level)
• Reorder Point: =AVERAGE(Daily Demand) * Lead Time + Safety Stock
• Order Recommended?: =IF((C2 + D2) < G2, "Yes", "No")
• Demand Variance: =ABS(F2 - C2)/F2 (used in performance KPIs)

Conditional Formatting Rules

• Highlight rows where Order Recommended? is "Yes" in red with bold text.
• Circle cells in the "Forecasted Sales" column that are below 10% of historical average (potential under-forecast).
• Color-code inventory levels:
  • Green: On-Hand Inventory ≥ Reorder Point
  • Orange: On-Hand Inventory between 50% and 90% of Reorder Point
  • Red: On-Hand Inventory < 50% of Reorder Point — high risk
• Apply data bars to the "Forecasted Sales" column to visualize growth trends.
