Table Structure and Columns (Invoice Generator Sheet)

Formulas Required

• E5 (Subtotal): =C5*D5
• G5 (Tax Amount): =E5*F5/100
• H5 (Total per Line Item): =E5+G5
• Invoice Total at bottom: Use: =SUM(H:H) in cell H10 (adjust based on table size)
• Service ID Auto-Generation: In cell A5, use: =IF(A4="",1,A4+1) and drag down. This ensures each new service gets a sequential ID.

Conditional Formatting Rules

• Overdue Payments Highlight: On the Payment Log sheet, apply conditional formatting to highlight rows where the payment date is more than 15 days past due.
• Total Amount > $100: Highlight cells in the Total column with a green background if value exceeds $100 for quick visual tracking of high-value invoices.
• Negative Tax Rate Warning: Use conditional formatting to flag any Tax Rate field below 0% or above 25% (with an alert).
• Empty Client Field: In the Invoice Generator, if client name is missing (from drop-down in cell B1), highlight that cell in red.
