Formulas Required

The template implements advanced Excel formulas to automate calculations:

• Billing Rate Lookup (in Time & Billing Log): =VLOOKUP([@Employee ID], tblEmployees, 4, FALSE) — Pulls the daily rate from the master list.
• Subtotal Calculation: =[@[Hours Worked]] * [@[Billing Rate ($)]
• Total Invoice Amount: =SUMIFS(tblInvoices[Subtotal Amount ($)], tblInvoices[Client Name], [Client Name]) + (SUMIFS(...) * TaxRate)
• Invoice Number Generation: =CONCATENATE("INV-", YEAR(TODAY()), "-", TEXT(ROW()-1, "000")) — Auto-increments with each new invoice.
• Daily Utilization Rate (in Dashboard): =SUMIFS(tblTimeLog[Hours Worked], tblTimeLog[Date], ">=Start", tblTimeLog[Date], "<=End") / (Total Available Working Hours)

Conditional Formatting

To enhance readability and highlight critical data points, the following conditional formatting rules are applied:

• Overdue Invoices: Background color red for any invoice with a due date older than today (using formula: =([Due Date]).
• High Utilization (>85%): Green fill in the dashboard to indicate top-performing employees.
• Negative Hours: Red text for any negative hours logged (error check).
• Billing Rate Above Average: Light yellow highlight for rates exceeding department average.
