Formulas Required for Productivity Improvement

The template includes a set of robust formulas designed to improve data accuracy and reduce repetitive tasks:

• Tax Calculation: =Total Amount * Tax Rate / 100 – automatically applies based on client or item settings.
• Discount Application: =Total Base * Discount % / 100 – dynamically adjusts final invoice value.
• Status Validation (Conditional): Uses IF statements to determine if an invoice is overdue based on current date and due date (e.g., =IF(TODAY()>Due Date, "Overdue", "Up to Date")).
• Automated Aging Reports: In the Pending Payments sheet, formulas calculate days overdue using: =TODAY()-Due Date.
• Total Revenue per Day: Daily Summary Dashboard uses SUMIF with date ranges to show daily totals.

Conditional Formatting Rules for Productivity Tracking

• Overdue Invoices: Cells in the "Status" column are highlighted red if due date is less than 30 days ago.
• Paid vs. Pending: Green background for "Paid", yellow for "Due in 7–30 days", red for overdue.
• High-Risk Clients: Conditional formatting flags clients with payment history below 90 days within last year (highlighted in orange).
• Tax Compliance Warning: If tax rate is not set, row turns amber to prompt user action.
