Formulas Required

The template relies on several key formulas to automate data processing:

• =TEXT(TODAY(), "YYYY-MM-DD"): Auto-fills current date in the "Date Issued" field.
• =IF([@Due Date]="", [@Date Issued]+30, [@Due Date]): Ensures due date is 30 days after issue unless manually set.
• =[@Quantity]*[@Unit Price]: Calculates Subtotal dynamically.
• =[@Subtotal]*[@Tax Rate]: Computes tax amount based on selected rate.
• =[@Subtotal]+[@Tax Amount]: Final total per line item.
• =IF([@Payment Status]="Paid", TODAY(), ""): Auto-populates "Date Paid" when status changes to “Paid”.

Conditional Formatting Rules

To enhance usability and data visibility, the following conditional formatting rules are applied:

• Overdue Invoices: Highlight rows in red if "Due Date" is earlier than today and "Payment Status" is not “Paid”.
• High-Value Invoices: Apply yellow background to any invoice with Total Amount > $1,000.
• Paid vs. Unpaid: Green for “Paid”, red for “Unpaid”, and amber for “Partially Paid”.
• Zero or Negative Prices: Flag invalid Unit Price entries (≤ 0) with a warning icon and red border.
