Sheet Names

Table Structures

The primary Invoice Master Data table is structured as a dynamic Excel Table (structured references) with the following columns:

Formulas Required

• Invoicing ID Auto-Generation: Use a helper column to count existing invoices and auto-generate the next number using: =IFERROR("INV-"&YEAR(TODAY())&"-"&TEXT(COUNTA($A$2:$A$1000)+1,"0000"), "INV-2024-")
• Due Date Calculation: =DATE(YEAR([@Date Issued]), MONTH([@Date Issued]), DAY([@Date Issued])) + VLOOKUP([@[Client ID]], Client & Vendor Registry!$A:$C, 3, FALSE)
• Subtotal: =[@Quantity]*[@[Unit Price (USD)]]
• Tax Amount: =[@Subtotal]*[@[Tax Rate (%)]]/100
• Total Amount Due: =[@Subtotal]+[@[Tax Amount]]
• Status Color Code: Conditional formatting based on value (e.g., red for "Overdue", green for "Paid").

Conditional Formatting Rules

• Overdue Invoices: Highlight rows where Due Date < TODAY() AND Status ≠ "Paid" in red.
• Pending Payments: Yellow background for invoices with Status = "Sent" but due date within 7 days.
• Status Indicator Icons: Use emoji icons (🟢, 🟡, 🔴) to represent Paid, Sent, Overdue.
• Total Amount Thresholds: Highlight any invoice over $100,000 in bold blue font.

User Instructions

1. Open the template and enable macros (if required for auto-generation).
2. Navigate to the Client & Vendor Registry sheet. Enter or verify all client/vendor data before creating invoices.
3. In the Invoice Master Data sheet, fill out each row using drop-downs and validated fields to prevent input errors.
4. The template automatically calculates totals, tax amounts, and due dates based on formulas.
5. Update the Status field as payment progresses (e.g., from "Sent" → "Paid").
6. Use the Summary Dashboard to monitor performance KPIs in real time.
7. Schedule monthly exports for tax reporting and audits via the Auto-Generated Reports sheet.
8. To maintain data integrity, avoid editing formulas directly. Use structured references only.
