Formulas Required

The template includes several key formulas to automate calculations and enhance functionality:

• Stock Status Flag (in a helper column): =IF(Current Stock < Reorder Level, "Low Stock", IF(Current Stock <= 0, "Out of Stock", "In Stock"))
• Inventory Value (Current): =Current Stock * Cost Price
• Days Until Reorder: =IF(Lead Time > 0, (Reorder Level - Current Stock) / (Average Daily Usage), "N/A") – Requires additional usage data input.
• Total Inventory Value (in Summary Dashboard): =SUMPRODUCT(Inventory[Current Stock], Inventory[Cost Price])
• Stockout Risk Score: =IF(Current Stock < Reorder Level, 1, 0) – used in alerts.

Conditional Formatting Rules

To improve data readability and user alertness, the following conditional formatting rules are applied:

• Low Stock Highlighting: When "Current Stock" is below "Reorder Level," cells are highlighted in yellow with a red border.
• Out of Stock Cells: When stock count is 0, background turns red and text becomes bold.
• High Value Products: Products with inventory value exceeding 50% of total value are highlighted in green.
• Category-Based Color Coding: Each product category is assigned a distinct color (e.g., blue for electronics, green for supplies).
• Reorder Alerts: The "Reorder Alerts" sheet uses red highlighting to show products due within 5 days.
