Table Structures and Columns (Inventory Master List)

The primary data hub is the Inventory Master List, structured as an Excel Table with the following columns:

Formulas Used for Automation and Accuracy

The template leverages dynamic formulas to reduce manual input errors and improve audit readiness:

• Product ID Auto-Increment: Uses =IF(A2="", MAX($A$1:$A$100)+1, A2) to assign unique IDs.
• Current Stock Quantity: Formula in the table: =SUMIFS(Transaction Log!C:C, Transaction Log!A:A, [Product ID], Transaction Log!D:D,"Addition") - SUMIFS(Transaction Log!C:C, Transaction Log!A:A, [Product ID], Transaction Log!D:D,"Sale")
• Low Stock Alert: =IF([Current Stock Quantity] < 5, "REORDER", "OK")
• Audit Flag Logic: =IF(ABS([Physical Count]-[Current Stock Quantity])>2,"Discrepancy Detected","No Issue")
• Inventory Value (USD): = [Current Stock Quantity] * [Cost Price]

Conditional Formatting Rules

To enhance visual oversight and prepare for audit review, the following conditional formatting rules are applied:

• Low Stock Items: Highlight in yellow if quantity is less than 5.
• Discrepancy Detected: Red fill with white text when the Audit Flag shows a mismatch.
• Expired or Discontinued Products: Gray background if Status is “Discontinued.”
• Selling Price Below Cost: Light red highlight if Selling Price < Cost Price (to flag potential pricing errors).
