Formulas Required

The template uses advanced Excel functions to ensure accuracy and automation:

• Avg. Monthly Sales Volume: =AVERAGEIF(SupplyList[Product ID], A2, SalesHistory[Sales Volume (Units)])
• Forecasted Sales (Units): =ROUND(AVERAGE(OFFSET(SalesHistory[Sales Volume (Units)], MATCH(A2, SalesHistory[Month/Year], 0)-6, 0, 6)), 1) * SeasonalFactor
• Seasonal Factor: =IF(MONTH(StartDate)=12, 1.35, IF(MONTH(StartDate)=7, 0.95, 1)) (Customizable per product category)
• Forecast Error (%): =ABS((Actual - Forecast) / Actual) * 100
• Reorder Alert Flag: =IF(CurrentStock < ReorderPoint, "REORDER NEEDED", "OK")

Conditional Formatting Rules

To enhance visual data analysis, the template includes the following dynamic formatting rules:

• Low Stock Alert: If Current Stock Level is below Reorder Point → Red background with bold text.
• High Forecast Error (>15%): Highlight in yellow to flag inaccurate models.
• Increasing Trend: Green arrow icon indicating rising sales volume over the last 3 months.
• Past Due Reorder: If Last Purchase Date is more than 30 days ago → Orange highlight.
