• Product Name: Text (up to 50 characters)
• Category: Text (dropdown list: Electronics, Construction Supplies, Apparel, etc.)
• Forecast Columns (Q1-Q4): Numeric integers or decimals
• Last Quarter Sales: Numeric (integers only)
• Current Stock Level / Reorder Point: Numeric, non-negative integers
• Lead Time (Days): Integer between 1–60 days

Formulas Required

• =SUM(Q1:Q4 Forecast) – Total annual forecast per product.
• =IF(Current Stock <= Reorder Point, "Order Now", "OK") – Alerts for low stock.
• =ROUNDUP((Forecasted Demand / 4) * Lead Time / 30, 0) – Estimated monthly reorder quantity (adjusted to nearest month).
• =AVERAGE(Historical Sales Data) – Used in the Forecast Summary sheet for baseline.
• =PERCENTILE.EXC(..., 0.75) – To calculate 75th percentile of historical sales for conservative forecasting.

Conditional Formatting

To enhance usability and quick data interpretation:

• Sales Growth Rate: Conditional formatting on forecast growth vs last quarter: green if increased, red if decreased.
• Forecast Accuracy Score: Color scale based on percentage difference between actual and forecasted sales (if updated).

User Instructions

2. Input Historical Sales: Fill in "Last Quarter Sales" from previous quarter (e.g., Q4 2023).
3. Add Forecast Values: Use past trends or market analysis to estimate Q1–Q4 demand. Use the forecast guidance in Sheet 5 if needed.
4. Set Reorder Points: Based on average weekly sales × lead time (recommended).
