All data is organized across multiple sheets with intuitive navigation. The workbook includes real-time KPI tracking, automated calculations, visual dashboards, and conditional formatting to highlight trends and risks—all essential for proactive financial decision-making.

Sheet Structure

The Excel file contains the following sheets:

1. Invoice Entries: Core data input sheet where each invoice is logged.
2. KPI Dashboard: Centralized view of all monitored KPIs with charts and summaries.
3. Customer Summary: Aggregates customer-level data for performance analysis.
4. Monthly Trends: Shows invoice volume, total revenue, and payment status over time.
5. Help & Instructions: Step-by-step guidance for users new to the template.

Table Structure: Invoice Entries Sheet

This is the primary input sheet where all invoices are recorded. Each row represents a single invoice issued to a client.

If the invoice is marked as “Paid,” this field records when payment was received.

Flagged based on Days to Pay: “On Time”, “Late”, “Overdue”.

Formulas Required

• Invoice ID Auto-Generator: =TEXT(TODAY(),"YYYY")&"-"&TEXT(COUNTA(A:A)+1,"000")
• Due Date: =DATE(YEAR([@Date Issued]),MONTH([@Date Issued]),DAY([@Date Issued]))+[@Credit Term]
• Days to Pay: =IF([@[Payment Date (if paid)]]="",TODAY()-[@Due Date],[@[Payment Date (if paid)]]-[@Due Date])
• KPI Tag: =IF([@[Days to Pay]]<=0,"On Time",IF([@[Days to Pay]]<=30,"Late","Overdue"))
• Total Paid Invoices: (Used in dashboard) =COUNTIF(Status, "Paid")
• Average Days to Pay: =AVERAGEIF(Status,"Paid",[@[Days to Pay]])
• On-Time Payment Rate: =COUNTIF(KPI Tag,"On Time")/COUNTA(KPI Tag)

Conditional Formatting Rules

To enhance visual clarity and help users quickly identify critical issues:

• Overdue Invoices: Highlight rows in red if Status is “Overdue”.
• Late Payments: Orange fill for invoices where Days to Pay > 0 but ≤ 30.
• Paid On Time: Green highlight for invoices with Days to Pay ≤ 0.
• Due Within 7 Days: Yellow background if Due Date is within the next week (using =AND([@Due Date]>=TODAY(),[@Due Date]<=TODAY()+7))
• KPI Dashboard Cells: Use color scales to display KPI scores from low (red) to high (green).

User Instructions

2. Navigate to the “Invoice Entries” sheet.
