Sheet Structure & Navigation

The template consists of five primary worksheets designed to work in unison:

• 1. Sales Forecasting Dashboard: The central hub displaying key performance indicators, forecasted sales trends, and inventory health metrics.
• 2. Historical Sales Data: A structured table capturing past sales performance by product, region, and date.
• 3. Current Inventory Levels: Real-time tracking of stock on hand, reserved quantities, and available stock across warehouse locations.
• 4. Forecasting Model & Calculations: The engine behind the forecasting process, housing formulas for trend analysis, seasonality adjustments, and automated predictions.
• 5. Product Master & Categories: A reference table listing all SKUs, product descriptions, category classifications (e.g., Electronics, Apparel), lead times, reorder points.

All data is organized within structured tables for ease of filtering and formula integration. The following are key table structures:

Formulas & Calculations

The template leverages advanced Excel functions to ensure dynamic and accurate forecasting:

• FORECAST.ETS(): Uses historical sales data to predict future monthly sales with automatic seasonality detection.
• SUMIFS() and AVERAGEIFS(): Calculate average monthly sales by SKU, region, or category for trend analysis.
• IF/AND Conditions: Determine "Action Required" status based on inventory levels relative to reorder points (e.g., IF(available < reorder_point, "Reorder", "Monitor")).
• Dynamic Date Ranges: Uses OFFSET or INDEX/MATCH to pull data from the last 12 months for trend modeling.

Conditional Formatting

To enhance readability and highlight critical inventory states:

• Red Fill: If Available for Sale < Reorder Point (indicating urgent need to reorder).
• Yellow Fill: If Available for Sale is between 20% and 80% of Reorder Point.
• Green Fill: If Inventory exceeds Reorder Point by more than 3x (indicating overstocking).
• Trend Arrows: In the Forecast Dashboard, up/down arrows show month-over-month forecast changes.
