Formulas Required

The following formulas are essential for automation and data integrity:

• Invoices Summary - Line Total Calculation: Use =SUMIFS([Invoice Details]!E:E, [Invoice Details]!A:A, [@Invoice ID]) to aggregate line totals per invoice.
• Invoice Details - Line Total: In the "Line Total" column: =Quantity * Unit Price
• Invoice Details - Tax Amount: In the "Tax Amount" column: =Line Total * (Tax Rate / 100)
• Audit Flag (Invoices Summary): Use conditional logic: =IF(OR(Tax Rate > 15%, Quantity > 100), "Yes", "") to flag high-risk or unusual entries for audit.
• Paid Status Color Logic: Conditional formatting based on text value (e.g., "Paid" in green, "Overdue" in red).

Conditional Formatting

To enhance visual clarity and aid audit reviewers:

• Audit Flag Column: Highlight cells with “Yes” in yellow background for immediate attention.
• Paid Status Column: Use color coding: green for "Paid", red for "Overdue", orange for "Partially Paid".
• Tax Rate & Line Total Columns: Highlight any values above industry average (e.g., tax rate > 10%) in light pink.
