Sheet: Payment Tracker

Sheet: Invoice Summary (Calculated)

This sheet automatically updates using formulas and is not directly editable except for user-defined settings. It provides a high-level overview:

• Total Number of Invoices
• Total Revenue Generated (before tax)
• Total Tax Collected
• Net Total (after tax)
• Outstanding Balance (Unpaid Invoices)
• Average Invoice Value

Formulas Required

• Tax Amount = Quantity × Unit Price × (Tax Rate / 100)
• Total Amount = (Quantity × Unit Price) + Tax Amount
• Status Logic: Uses IF statements to determine status based on date and payment data.
• Outstanding Balance: SUMIF of all invoices where Status = "Sent" or "Draft", minus Payment Tracker entries.
• Average Invoice Value: =AVERAGE(Invoice Summary!Total Amount)
• Cash Flow Status: IF(SUM(Payment Tracker!Amount Paid) > SUM(Invoices!Total Amount), "Positive", IF(SUM(Payment Tracker!Amount Paid) < SUM(Invoices!Total Amount), "Negative", "Neutral")))

Conditional Formatting Rules

• Overdue Invoices: Cells in the “Status” column highlight red if the Date Due is less than today’s date.
• Paid Invoices: Green background with bold text when status = "Paid".
• Late Payments: Payment Tracker entries where "Date Received" > due date are highlighted in orange.
• High Revenue Entries: Total Amount > $500 is marked in yellow to flag large invoices.
