Table Structures and Columns (Main Maintenance Log)

The main data sheet uses structured Excel Tables to ensure scalability and formula reliability. The table is named Main_Maintenance_Log.

Formulas Required

• Next Due Date:
  =IF([@Status]="Completed",[@[Last Maintenance Date]] + [@Frequency], IF([@Status]="Overdue",[@[Last Maintenance Date]] + [@Frequency], ""))
• Days Until Next Due:
  =IF(AND([@Status]<>"Completed",[@[Next Due Date]]<>""),[@[Next Due Date]] - TODAY(), IF([@Status]="Overdue",TODAY() - [@Last Maintenance Date], ""))
• Overdue Indicator (for Conditional Formatting):
  =AND([@Status]<>"Completed",[@[Next Due Date]]<=TODAY())
• Asset ID Generation:
  =CONCATENATE(LEFT([@Category],2), "-", TEXT(TODAY(),"YYMMDD"), "-", RIGHT("00" & ROW(),3))
• Status Auto-Update (Dynamic):
  Use a VBA macro or formula-driven logic to update status based on due dates and completion.

Conditional Formatting Rules

• Overdue Items: Red fill, bold text for rows where [Next Due Date] < TODAY() and status ≠ "Completed".
• Pending Maintenance (within 7 days): Yellow highlight with warning icon.
• Completed Tasks: Green background with checkmark emoji.
• Status Column: Color-coded dropdown indicators (Red: Overdue, Amber: Pending, Green: Completed).

User Instructions

To use this template effectively for startup planning, follow these steps:

1. Customize Categories: Modify the dropdown lists in the "Equipment & Asset Register" sheet to match your startup’s infrastructure.
2. Add New Assets: Enter assets into the "Asset Register" – this auto-populates names and categories in the main log.
3. Schedule Maintenance: Fill out each row with relevant data. The system auto-calculates due dates based on frequency.
4. Update Status: Change the status field as work progresses. Use conditional formatting to identify risks early.
5. Analyze Dashboards: Use the KPI dashboard to assess maintenance load, identify bottlenecks, and forecast resource needs for scaling.

Pro Tip: Link this template with your startup’s project management tool (e.g., Asana or ClickUp) using Power Query or API integrations to sync data in real time.
