The Challenge
The HR and operations teams struggled to maintain accurate daily attendance and monthly leave records due to a manual and disconnected tracking process. While employee work hours were logged consistently in TeamLogger, consolidating, classifying and updating structured monthly attendance sheets required significant manual effort.
Without an automated system, maintaining accuracy, consistency and timely reporting became increasingly difficult as the team expanded.
Key Pain Points
-
1
Lack of Centralized Daily & Monthly Visibility
-
2
Heavy Manual Effort for Daily Updates
-
3
Risk of Calculation Errors & Leave Miscounts
-
4
Delayed Reporting to Stakeholders
The Automation Solution
To eliminate manual attendance tracking and ensure accurate daily and monthly leave consolidation, a fully automated Attendance & Leave Management System was built using n8n, with TeamLogger as the primary data source and Google Sheets as the centralized reporting layer. The automation runs on a fixed daily schedule and handles data extraction, classification, sheet updates, formatting, and stakeholder notification without manual effort.
Automated Daily Execution
The workflow runs automatically every day and calculates the previous day’s date range in IST. This ensures accurate attendance processing without manual date selection and prevents reporting inconsistencies.
Monthly Sheet Identification
The system connects to the Google Sheets API and dynamically identifies the sheet for the current month based on the reporting date.This removes the need for manual sheet switching and ensures updates always occur in the correct sheet.
Employee Work Summary Collection
The workflow retrieves employee work summaries from the TeamLogger API for the selected date range. By pulling data directly from the source system, it ensures reliable and accurate attendance records.
Work Hour Processing
Employee work hours are converted from decimal format to HH:MM:SS and mapped to the correct day column in the monthly sheet.This eliminates manual time conversion errors and ensures structured data entry.
Automated Attendance Classification
Based on predefined hour thresholds, employees are automatically categorized as Present, Short Leave, Half Day, or Absent. This rule-based logic ensures consistent and unbiased attendance marking.
Attendance & Leave Updates
The workflow updates each employee’s daily status, increments cumulative totals, and synchronizes leave balances in the master sheet. This keeps monthly records accurate and centralized.
Visual Formatting
Using the Google Sheets batchUpdate API, conditional formatting is applied to visually distinguish attendance types, improving clarity for HR and management.
Automated Summary Email
Once processing is complete, a structured HTML email summarizing Absent, Half Day, and Short Leave employees is automatically sent to stakeholders, ensuring timely communication.
Stability & Scalability
Timezone handling, structured logic, and controlled API execution ensure smooth performance, making the system reliable and scalable as the organization grows.
