Required Formulas for Automation & Accuracy

• =IF(COUNTIF(ClientDetails[Client ID], A2)>1, "Duplicate", "Valid") – Ensures uniqueness of Client IDs.
• =TEXT(TODAY(), "mm/dd/yyyy") – Auto-populates current date in 'Last Contact Date' or 'Date Issued' fields.
• =IF(ProjectsAndTasks[Status]="Completed", "✓", IF(ProjectsAndTasks[Progress %] = 100%, "✓", "")) – Visual confirmation of completion.
• =SUMIF(BillingAndInvoicing[Client ID], ClientDetails[@Client ID], BillingAndInvoicing[Amount Due]) – Calculates total revenue for each client dynamically.
• =IF(AND(BillingAndInvoicing[Due Date] <= TODAY(), BillingAndInvoicing[Status]="Pending"), "Overdue", IF(BillingAndInvoicing[Status]="Paid", "Paid", "On Time")) – Flag for overdue invoices using conditional logic.
• =ROUND(AVERAGEIFS(ProjectsAndTasks[Progress %], ProjectsAndTasks[Client ID], ClientDetails[@Client ID]), 2) – Computes average project progress per client.

Conditional Formatting Rules

• Overdue Invoices: Red fill with white text for any invoice where Due Date is earlier than today and Status ≠ Paid.
• Pending Follow-Ups: Yellow highlight for entries in Communication Log where Next Action Required exists and Status Flag is Pending.
• Project Completion: Green fill with checkmark emoji (✓) when Progress % = 100% or Status = Completed.
• High-Value Clients: Light blue background for clients with Total Revenue > $50,000 (configurable threshold).
• Client Status: Color-coded status tags: Green (Active), Gray (Inactive), Red (Lost).
