Formulas Required

The template uses dynamic formulas to automatically update values and detect trends:

• =VLOOKUP(A2, Inventory!A:B, 2, FALSE): Links usage records to inventory descriptions.

Conditional Formatting

The template includes visual cues to help users quickly identify issues:

• Low stock items (Current Stock < Reorder Level) are highlighted in red.
• Items with cost increases over 10% from average are shaded in yellow.
• The Dashboard sheet uses green for positive trends and red for negative variance.
• Alerts appear as bold text with warning icons (simulated via color).
