Formulas Required

The template uses a combination of built-in Excel functions to automate calculations and ensure accuracy:

• SUMIFS(): Aggregates line item totals by client or date range.
• IF() and VLOOKUP(): Determines status (e.g., if due date passed → "Overdue").
• DATEADD() (via Excel Date Functions): Automatically calculates Due Date = Invoice Date + 30 days.
• =ROUND(TOTAL * TAX_RATE, 2): Formats tax to two decimal places.
• =SUMIFS(Invoice Line Items[Line Total], [Status], "Paid"): Calculates total paid revenue.
• MAX() and MIN() for finding the earliest/latest invoice or payment date.

Conditional Formatting

To improve usability, the template applies intelligent conditional formatting:

• Overdue Invoices: Cells in "Status" column turn red if due date is passed (using IF + DATE logic).
• Paid Invoices: Green background with a checkmark icon.
• High Value (>1000): Yellow highlighting for large invoices to draw attention.
• Missing Tax ID: Red warning in client records where tax field is blank.
• Duplicate Invoices: Alerts if an invoice ID already exists (using COUNTIF).
