• =SUMIF(Invoice!C:C, "Paid", Invoice!E:E): Sums all paid invoice amounts across the sheet.
• =IF(DATE(2025,6,30) - [Due Date] < 0, "Overdue", "On Time"): Flags overdue invoices in red.
• =SUMIFS(Payments!E:E, Payments!D:D, A1): Calculates total received from a specific customer.

Conditional Formatting Rules

To enhance readability and user awareness:

• Cells with "Overdue" status are highlighted in red.
• Due dates past 14 days are shaded light orange.
• All zero or negative values in the Quantity or Unit Price columns turn gray with warning message.
• Total amounts over $10,000 in any invoice trigger a yellow highlight for review.
