Table Structures & Data Types

1. Sales History Table (Sheet: Sales History)

2. Product Catalog Table (Sheet: Product Catalog)

3. Stock Levels & Movement Table (Sheet: Stock Levels)

Key Formulas Used

• Sales Forecast (Sales Forecast Sheet): Uses a combination of =FORECAST.ETS() for exponential smoothing and seasonality, with adjustments based on trend analysis.
• Dynamic Stock Balance: In the Stock Levels sheet, uses a running sum via =SUMIFS() and OFFSET()-based cumulative calculations to track inventory changes over time.
• Reorder Alert Logic: Conditional formula: =IF([Stock Balance] <= [Reorder Level], "REORDER", "OK")
• Predictive Demand Calculation: Incorporates seasonal indices using =AVERAGEIFS() and normalization factors from historical data.
• Automated PO Suggestion: Formula determines required order quantity: =MAX(0, [Forecasted Demand for Next 30 Days] - [Current Stock]) + Safety Stock

Conditional Formatting Rules

• Stock Level Status: Green (≥ Reorder Level), Yellow (Between Reorder and Max), Red (< Reorder Level).
• Sales Forecast Variance: Color-coded bars showing over-forecast vs under-forecast (Red: >10% variance; Green: <5% variance).
• Inventory Turnover Rate: Conditional formatting highlights products with turnover below industry benchmark.
• Date-based Alerts: Highlight rows where stock is low and lead time exceeds current date, indicating urgency.
