Formulas Required

The template leverages Excel's built-in functions to automate reporting and reduce errors:

• Log ID Auto-Generation: =TEXT(COUNTA(MaintenanceLog[Log ID])+1,"MNT-00#") — auto-generates unique IDs.
• Resolution Time (Hours): =IF([@Status]="Resolved", ([@Date Resolved]-[@Date Reported])*24, "")
• Status Color Logic: Uses conditional formatting with formulas to highlight status states.
• Client Summary Dashboard: Uses SUMIFS, COUNTIFS, and AVERAGEIFS to calculate KPIs per client (e.g., average resolution time, number of issues).
• Duplicate Detection: Formula checks for duplicate entries using COUNTIF.

Conditional Formatting

To enhance readability and prioritize critical information:

• Status Column: Red background for "Open", yellow for "In Progress", green for "Resolved/Closed".
• Resolution Time (Hours): Orange if > 24 hours, red if > 72 hours.
• Billing Status: Red text for "Not Invoiced", green for "Paid".
• Date Reported: Highlights entries older than 1 week in light gray.
