Formulas Required for Advanced Functionality

• Sales Forecasting Model: Uses a combination of =FORECAST.LINEAR(), =TREND(), and custom exponential smoothing formulas that reference the Historical Sales Data sheet with time-series decomposition.
• Confidence Interval Calculation: Implements standard error formulas based on residuals: Forecast ± (Z-score × Standard Error).
• Bills Overdue Indicator: Uses conditional logic: =IF(TODAY() > [Due Date], TODAY() - [Due Date], 0)
• Risk Level Assignment: =IF([Days Past Due] >= 30, "High", IF([Days Past Due] >= 15, "Medium", "Low"))
• Forecast Accuracy: =AVERAGE(ABS((Actual - Forecast) / Actual)) * 100, calculated dynamically from historical data.
• Dynamic Dashboard KPIs: Uses =SUMIFS(), =COUNTIF(), and structured references for real-time updates.

Conditional Formatting Rules

• Bills Overdue (Red Fill): Apply red background to rows where "Days Past Due" > 0.
• Risk Level Coloring: Use color scale: Low (Green), Medium (Yellow), High (Red).
• Forecast Accuracy Rate: Green if ≥ 90%, Yellow if between 85%–89%, Red otherwise.
• Status Flag Color Coding: "On Track" = Green, "At Risk" = Orange, "Delayed" = Red.
• Trend Arrows in Dashboard: Insert small up/down icons using data bars and icon sets to show sales trend direction.
