Table Structures & Columns (Inventory Master List Example)

The primary data table is located on the Inventory Master List sheet, structured as a dynamic Excel Table with filtering and sorting capabilities.

Formulas Required

• Inventory Value Calculation:
  = [Current Quantity on Hand] * [Standard Cost per Unit]
  Placed in a calculated column: "Total Inventory Value ($)".
• Age of Stock (Days):
  = TODAY() - [Last Count Date]
  Helps identify stale inventory requiring review.
• Reorder Point Alert:
  = IF([Current Quantity on Hand] <= [Reorder Level], "Order Needed", "")
  Uses a hidden column for Reorder Level (set by procurement policy).
• Inventory Accuracy Rate (Dashboard):
  = (COUNTIF([Counted Quantity], [On Hand]) / COUNTA([On Hand])) * 100
  Calculated dynamically in the Audit Readiness Dashboard.

Conditional Formatting Rules

• High Variance Alerts: Highlight rows where |[Counted Quantity] - [On Hand]| > 10%, using red fill.
• Overdue Counts: If the difference between today and Last Count Date exceeds 90 days, highlight in yellow.
• Reorder Required: Use green text for items flagged as "Order Needed".
• Duplicate SKUs: Apply rule to detect duplicate entries using formula: =COUNTIF($A$2:$A$1000, A2) > 1.
