Sheet Names

The template includes four primary sheets:

1. Invoice Entry: Main data input sheet for recording monthly invoices.
2. Summary & Productivity Metrics: Aggregated dashboard showing revenue, overdue amounts, and productivity indicators.
3. Payment Tracking: Monitors payments received and due dates with status flags.
4. Settings & Formulas: Hidden sheet containing all formulas, formatting rules, and version control information (for internal use).

Table Structures & Column Details

The core data table in the "Invoice Entry" sheet is structured to capture all essential invoice elements with clear data types:

All data fields are validated with appropriate data types: dates, currency (USD), text, and status flags. The "Total Amount" column is calculated automatically using a formula.

Formulas Required

The following formulas ensure dynamic calculations and automation:

• Total Amount = Units × Unit Price: Automatically computed in cell E3 for each row.
• Monthly Revenue Total: Uses SUMIFS to aggregate all "Paid" invoices by month across the sheet.
• Overdue Flag Detection: If Due Date < Today(), then Status is marked as “Overdue” using IF function.
• Auto-increment Invoice ID: Uses a formula with dynamic text and date to generate unique IDs (e.g., A1023-MYR).
• Due Date Reminders: Conditional formatting triggers a color alert when due dates fall within 7 days.

Conditional Formatting Rules

To enhance visual productivity and quick data interpretation, the following conditional formatting rules are applied:

• Status Color Coding: Green for "Paid", Yellow for "Pending", Red for "Overdue".
• Due Date Alerts: Rows where Due Date is within 7 days of today turn the row background orange.
• High-Value Invoices: Invoices over $1,000 are highlighted in bold blue text.
• Missing Data Warnings: Cells with empty "Client Name" or "Description" appear in red with a warning message.

User Instructions

1. Open the template and navigate to the Invoice Entry sheet.
2. Enter invoice details, ensuring all required fields are filled. The system will auto-calculate total amount.
