Formulas Required

The template includes a variety of dynamic formulas to ensure real-time accuracy:

• =SUMIFS(TimeEntries!D:J, TimeEntries!C:C, "Project X", TimeEntries!F:F, ">=" & StartDate) – Aggregates hours per project and date range.
• =VLOOKUP(A2, TeamMembers!A:B, 2, FALSE) – Pulls hourly rate based on team member name.
• =SUMIFS(TimeEntries!E:E, TimeEntries!B:B, [Project Name], TimeEntries!I:I, "Approved") – Calculates total approved hours per project.
• =IF(Invoice!G:G > Invoice!H:H, "Overdue", IF(Invoice!H:H < TODAY(), "Due Soon", "Paid")) – Auto-determines payment status.
• =SUMPRODUCT((TimeEntries!B:B = [Project Name]) * (TimeEntries!E:E)) – Calculates total time per project using array formula.
• =IF(Invoice!C:C = "", "No Project Assigned", Invoice!C:C) – Validates invoice-project linkage.

Conditional Formatting

The template uses conditional formatting to visually highlight critical data:

• Overdue Invoices: Cells in the "Payment Status" column turn red if due date is past today.
• High-Time Projects: Rows in Time Entries with duration > 10 hours are highlighted in orange.
• Paid vs. Unpaid: Invoices with status "Paid" are green; "Partial" is yellow; "Overdue" is red.
