Columns and Data Types

• Product ID: Text (e.g., P1001), unique identifier.
• Product Name: Text, descriptive name of the item.
• Category: Text (e.g., Electronics, Furniture) for filtering and grouping.
• Sales Forecast (per month): Number (integer), based on historical trends and seasonal factors.
• Current Stock: Number, reflects real-time inventory from the Ledger sheet via VLOOKUP or INDEX/MATCH.
• Reorder Point: Number, calculated as (Average Daily Demand × Lead Time) + Safety Stock.
• Recommended Order Qty: Number, derived using EOQ (Economic Order Quantity) model or safety stock buffer.

Formulas Required

• =FORECAST.LINEAR(NextMonth, SalesRange, DateRange): Predicts next period’s demand using linear regression.
• =AVERAGEIFS(HistoricalSales!C:C, HistoricalSales!A:A, [ProductID], HistoricalSales!B:B, ">="&StartPeriod): Calculates average sales for a specific product and time window.
• =VLOOKUP([ProductID], ProductMasterList!A:E, 5, FALSE): Retrieves lead time from Master List.
• =(AverageDailyDemand * LeadTime) + SafetyStock: Computes reorder point.
• =SQRT((2 * AnnualDemand * OrderCost) / HoldingCost): EOQ formula for optimal order quantity.

Conditional Formatting

• Red fill and bold text for rows where Current Stock < Reorder Point (critical alert).
• Yellow highlight when stock is between 70–90% of reorder point (warning zone).
• Green background if recommended order quantity = 0 (no action needed at current levels).
• Data bars in the "Forecasted Sales" columns to visualize trends.

User Instructions

1. Populate the Historical Sales Data sheet with actual past sales data (at least 12 months).
2. Enter current inventory levels in the Inventory Ledger.
3. Add all products to the Product Master List, including category, cost, and lead time.
4. The Planning View will auto-populate via formulas; no manual entry is needed.
5. Adjust forecasting parameters in the Forecasting Models & Settings sheet as business conditions change (e.g., seasonality factors).
6. Review alerts and recommended actions. Generate purchase orders based on "Recommended Order Qty".
7. Update the Inventory Ledger with new shipments to reflect real-time stock.

Example Rows

Note: Current stock is below reorder point—recommend order 60 units immediately.

Recommended Charts and Dashboards (Sheet 6)

• Line Chart: Monthly forecast vs. actual sales (over time) to monitor accuracy.
• Bar Chart: Top 10 products by forecasted demand for prioritization.
• Pie Chart: Inventory distribution by category (showing which categories are over/understocked).
• Gantt-style Timeline: Visualize reorder recommendations and expected delivery dates.
