Formulas Required

The template uses dynamic Excel formulas to automate calculations and maintain data integrity:

• =IF(D4 < E4, "Low", IF(D4 <= 0, "Out of Stock", "Normal")): Determines reorder status based on stock vs. reorder point.
• =TODAY() + G4: Calculates next reorder date using lead time (in days).

• =VLOOKUP(A2, InventoryMaster!A:B, 2, FALSE): Fetches product name from master table.

Conditional Formatting

The template uses conditional formatting to visually highlight critical data:

• Red background for stock levels below reorder point in Weekly Stock Levels.
• Yellow highlighting for any negative balance or returns exceeding sales.
• Green fill when inventory is above 80% of safety stock level.
• Pulse animation (in Excel with conditional formatting) on alerts to draw attention to urgent items.
