Table Structures & Columns (Invoice Data Sheet)

The main Invoice Data sheet features a structured table named InvoicesTable, which is essential for maintaining clean, organized data. The table includes the following columns with appropriate data types:

Formulas Required

The template utilizes several key formulas to automate data calculation and validation:

• Invoice ID: =CONCAT("INV-", YEAR(TODAY()), "-", TEXT(ROW()-1,"000"))
  This auto-generates a unique, sequential invoice number based on the current year.
• Due Date: =DateIssued + 30
  Automatically sets the due date 30 days after issue.
• Total Amount: =Quantity * UnitPrice
• Tax Amount: =TotalAmount * TaxRate
• Grand Total: =TotalAmount + TaxAmount
• Status Color Tagging (Conditional Formatting): Uses formulas to trigger color changes based on status.

Conditional Formatting Rules

• Overdue Invoices: If Status = "Overdue" AND Due Date < TODAY(), apply red highlight with bold text.
• Paid Invoices: If Status = "Paid", apply green background and checkmark icon.
• Due Soon: If Due Date is within 5 days from today, highlight in yellow with orange border.
• Total Amount > $1000: Apply bold and blue text to high-value invoices for quick visibility.
