Formulas Required for Automation and Accuracy

• Reorder Point Formula (in Inventory Master): =Safety_Stock + (Average_Daily_Sales * Lead_Time_Days)
• Average Daily Sales Calculation: Use this formula in the Forecasting Engine: =AVERAGE(Sales_History[Sales Volume]) / 30
• Moving Average (3-Month): =AVERAGEIFS(Sales_History[Sales Volume], Sales_History[Sales Month], ">="&DATE(YEAR(TODAY())-1,MONTH(TODAY()),1), Sales_History[Sales Month], "<="&TODAY())
• Seasonality Multiplier (in Settings): Users define monthly multipliers (e.g., 1.3 for December) which are applied in forecasting.
• Forecasted Sales (Future Months): =ROUND(Average_Daily_Sales * 30 * Seasonality_Multiplier, 0)
• Last Updated Timestamp: Use VBA or a formula like: =IF(OR([@Product Name] <> "", [@Current Stock] <> ""), TODAY(), "")

Conditional Formatting for Visual Clarity

• High Sales Volume: Apply green gradient to top 10% of sales volume entries to identify best-sellers.
