Sheet Names

The template consists of five structured sheets to ensure organization and ease of use:

Table Structures and Columns

1. Invoice Summary (Main Sheet)

2. Line Items & Services Table

Formulas Required for Automation and Accuracy

• Auto-Generate Invoice Number: =CONCATENATE("INV-", YEAR(TODAY()), "-", TEXT(ROW()-1, "000")) (in cell A2 on Invoice Summary)
• Due Date: =DATE(YEAR([Date Issued]), MONTH([Date Issued]), DAY([Date Issued]) + 30)
• Total Amount: =SUM('Line Items & Services'!F:F) on Invoice Summary
• Tax Amount: =IF(LEN([Tax Rate])=0, 0, [Subtotal] * [Tax Rate]) in the line item table
• Invoice Status Logic:

  =IF(AND(TODAY() > DueDate, InvoiceStatus<>"Paid"), "Overdue", 
              IF(TODAY() < DueDate, "Pending", "Paid"))

Conditional Formatting Rules

• Overdue Invoices: Highlight in red if status is "Overdue" and due date is past.
