Formulas Required

Status Auto-updates: Use nested IF and TODAY() functions: =IF(AND([@Status]="Active", [@Contract End Date] <= TODAY()+14), "Expiring Soon", IF([@Status]="Active", "Active", IF([@Contract End Date] < TODAY(), "Terminated", [@Status])))
Renewal Alerts: Conditional logic with: =IF([@Renewal Due Date] <= TODAY()+30, "Urgent - Renew in 30 Days", IF([@Renewal Due Date] <= TODAY()+60, "Action Required", ""))
Client Tier Calculation: Use VLOOKUP to assign value tiers based on contract amount: =IF([@Total Contract Value (USD)] >= 50000, "Platinum", IF([@Total Contract Value (USD)] >= 25000, "Gold", IF([@Total Contract Value (USD)] >= 10000, "Silver", "Bronze")))
Dashboard KPIs: Use COUNTIF and SUMIFS for totals: =SUMIFS([Total Contract Value (USD)], [Status], "Active")

Conditional Formatting Rules

Expiring Soon: Red fill with yellow text for rows where contract ends within 14 days.
Renewal Status: Color-coded: Green (Confirmed), Orange (In Progress), Red (Overdue).
Client Tier Highlighting: Use color scales: Platinum = Dark Blue, Gold = Yellow, Silver = Gray, Bronze = Light Gray.
