• Products/Services Table: Holds service or product ID (PK), description, unit price, category (e.g., IT Services, Maintenance), tax classification.
• Payments Table: Tracks payment ID (PK), invoice ID (FK), amount paid, date received, payment method (cash/check/online), and reference number.

Formulas Required

The template leverages powerful Excel formulas to ensure accurate and dynamic calculations:

• Tax Calculation: =IF([Tax Rate] > 0, [Total Before Tax] * [Tax Rate]/100, 0)
• Total Amount: =SUMPRODUCT(Quantity Column * Unit Price Column) + Tax Amount
• Due Date Calculation: =DATE(YEAR([Issue Date]), MONTH([Issue Date]), DAY([Issue Date])) + 30
• Status Update Logic (Conditional): IF(AND(TODAY() > Due Date, Status = "Sent"), "Overdue", IF(Status = "Paid", "Paid", "Pending"))
• Auto-Invoice Number: =CONCATENATE("INV-", TEXT(YEAR(TODAY()), "000"), "-", TEXT(MONTH(TODAY()), "00"), "-", ROW(A1))
• Running Balance (in Payments sheet): =SUMIF(Invoices!$B:$B, [Customer ID], Invoices!$G:$G) - SUMIF(Payments!$C:$C, [Customer ID], Payments!$D:$D)

Conditional Formatting

The template uses conditional formatting to highlight key business operations insights:

• Overdue Invoices (Red Background): If due date is before today and status is “Sent” → applies red fill.
• Paid Invoices (Green Background): When payment status equals "Paid" → green highlight.
• High-Value Invoices (> $10,000): Bold font and yellow background when total exceeds threshold.
• Missing Payment Info: If a payment record has no date or amount, applies orange warning border.
• Status Changes (Dynamic Color Coding): Shifts color based on status: blue (draft), green (sent), red (overdue).
