A2Z Group

A2Z

A2Z Group

Engineering Solutions & Workforce Operations — India

Founded in 2002 by IIT alumnus Mr. Amit Mittal, A2Z Group is a major engineering solutions provider across power, telecom, waste management, and renewable energy. With over 12,000 professionals across India and beyond, the company required a robust HR and payroll ecosystem capable of supporting distributed workforce operations at enterprise scale.

02 — Challenges Faced

What Was Holding A2Z Group Back

A2Z Manpower needed an HR system that could handle operational complexity, workforce scale, and regional accessibility. Existing systems were creating friction across multiple critical workflows.

Lack of Customization

Off-the-shelf HR tools could not accommodate A2Z’s specific workflows, manpower structures, and operational requirements.

Scalability & Integration Issues

Managing 12,000+ employees across 100+ sites and 40+ clients demanded a platform that could scale and integrate cleanly with evolving modules.

Limited Digital Access

Employees depended on calls and emails to connect with HR, slowing communication and making self-service nearly impossible.

Multilingual Requirements

A diverse workforce speaking different Indian languages needed a system that was accessible, localised, and easy to use across regions.

03 — Solutions Developed

How Auriga IT Built the A2Z HR Ecosystem

Auriga IT implemented a tailored ERPNext and Frappe HR solution that unified workforce management, employee self-service, payroll processing, geo-based attendance, and supervisor workflows into one scalable platform.

Centralized Web-Based HR Platform

Auriga IT developed a centralized ERP solution to streamline HR processes and automate payroll activities across A2Z’s distributed workforce. The platform connected core HR functions in a single operational system, improving consistency and efficiency across locations.

Cross-Platform Mobile App for Employees and Supervisors

A mobile app was launched on both the Play Store and App Store, giving employees and supervisors direct access to essential HR workflows without depending on manual intervention from HR teams.

Authentication & Security

Mobile OTP Login

SMS-based verification for secure employee access

Biometric Security

Fingerprint and FaceID support after OTP verification

A2Z Group mobile app login screen with authentication flow

A2Z Group secure login screen with mobile authentication

Employee Features

Geo Check-Ins

Location-based attendance and workforce tracking

Leave Management

View balances, request leave, and track approvals

My Pay

View and download salary slips by month

Profile Management

Update personal details, documents, and family records

Aadhaar-Based Employee Onboarding

Employees’ Aadhaar numbers and supporting documents such as Aadhaar card, PAN card, and police verification reports were validated by HR before app access was granted, ensuring a secure and verified onboarding process.

Roster Management for Distributed Staff

Auriga IT implemented a web-based roster management solution that allowed supervisors to manage customized schedules for security and hospitality staff across the country, aligned with A2Z’s specific workforce needs.

Geo-Fencing and Payroll Automation

Geo-fencing technology was integrated to calculate overtime accurately based on employee attendance and location. That overtime data then flowed directly into payroll processing for timely and precise compensation.

Multilingual Access and Ticketing Support

The platform was designed to support multiple Indian languages, improving accessibility for employees across regions. A client-facing ticketing panel also allowed attendance, payroll, and billing concerns to be raised directly for faster resolution.
