Formulas Used in the Template

The template leverages simple yet powerful Excel formulas to ensure accuracy and reduce manual input errors:

Invoice Number (A1): =IFERROR("INV-"&TEXT(TODAY(),"YYYY")&"-"&TEXT(ROW()-1,"000"), "") – automatically generates a unique, sequential invoice number.
Due Date (C1): =B1+14 – sets payment due 2 weeks after invoice issuance.
Subtotal (H1): =F1*G1
Tax Amount (J1): =H1*(I1/100)
Total Amount Due (K1): =H1+J1
Payment Status (L1): Use Data Validation to create a dropdown with options: “Pending”, “Paid”, “Overdue”.

Conditional Formatting Rules

To enhance visual clarity and improve invoice tracking, the following conditional formatting rules are applied:

Overdue Invoices: If the current date exceeds the Due Date (C1), cell K1 turns red with white text.
Paid Invoices: When Payment Status is "Paid", the entire row background changes to light green.
Pending Invoices: Rows with status "Pending" are highlighted in yellow to draw attention.
Subtotal & Total Formatting: Amounts are formatted using currency format with two decimal places for consistency.
