A2Z Group: Workforce Operations Across 12,000 Employees and 100 Sites

ERPNext HR, Payroll & Finance Case Study

A2Z Group had grown to 12,000+ employees across 100+ sites and 40+ clients, but off-the-shelf HR tools couldn't keep pace, workforce data stayed fragmented across locations, and finance ran on spreadsheets and Tally with GST filed through a separate portal. Auriga IT built a tailored ERPNext platform to unify workforce operations, automate multi-component payroll with full Indian statutory compliance, give employees mobile self-service backed by geo-fencing attendance, and bring procurement, project-wise revenue tracking, and financial reporting onto the same system.

01 - About the Client

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, the company needed one ERP system built to support distributed workforce operations and finance at enterprise scale across 100+ sites and 40+ clients.

02 - Challenges Faced

What Was Holding A2Z Group Back

A2Z Group faced five critical system challenges: off-the-shelf HR tools that could not be customized for their workflows, scalability and integration limitations across 12,000+ employees and 100+ sites, employees lacking digital self-service access, no multilingual support for a diverse regional workforce, and finance operations running on spreadsheets and Tally with no single system to trace project-wise revenue.

A2Z Group needed a system that could handle operational complexity, workforce scale, regional accessibility, and financial traceability across every project and site. Existing tools and processes were creating friction across multiple critical workflows.

01
Lack of Customization
Off-the-shelf HR tools could not accommodate A2Z's specific workflows, multi-formula salary structures, manpower structures, and operational requirements across diverse industry verticals.
02
Scalability and Integration Issues
Managing 12,000+ employees across 100+ sites and 40+ clients demanded a platform that could scale and integrate cleanly with evolving HR, payroll, and Indian statutory compliance modules.
03
Limited Digital Access
Employees depended on calls and emails to connect with HR, slowing communication and making self-service — payslip access, leave balance, attendance regularization — nearly impossible for a distributed workforce.
04
Multilingual Requirements
A diverse workforce speaking different Indian languages needed a system that was accessible, localised, and easy to use across regions without language barriers.
05
Fragmented Financial Operations
Accounting ran on spreadsheets and Tally, GST was filed through a separate portal, and project-wise revenue and cost could not be traced without manual reconciliation across 100+ sites and 40+ clients.
03 - Solutions Developed

How Auriga IT Built the A2Z HR and Finance Ecosystem

Auriga IT delivered eight integrated solutions on ERPNext and Frappe HR: a centralized web HRMS platform with multi-component payroll, a cross-platform mobile app with full employee self-service, Aadhaar-based onboarding, roster management for distributed staff, a geo-fencing attendance-to-payroll pipeline with conflict resolution, Indian statutory compliance (PF, ESIC, PT, LWF, Bonus), multilingual access with a client ticketing panel, and a finance and procurement layer built on ERPNext's accounting module.

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

1

Centralized Web HRMS Platform

Auriga IT built the core HRMS on ERPNext and Frappe HR as a single web platform covering every stage of the employee and client lifecycle. HR administrators manage company and client records, employee master data, shift and attendance rules, leave policies, payroll processing, employee promotions, and role-based permissions from one desk.

Core HRMS Modules
Company and Clients
Entity, client, client site, and contract records in one place
HR
Employee master, check-ins, identity documents, shift type, and shift assignment
Payroll
Payroll entry, salary structure, tax exemption, benefit claims, and LOP reversal
Attendance and Leaves
Attendance import, daily attendance tool, leave application, allocation, and policy
Employee Promotion
Promotion workflow linked directly to salary structure and appraisal calculation
Masters and Role Permissions
ESIC subcodes, document types, designations, and role-based access control
Multi-Component Salary Structures

Payroll at A2Z operates on multiple salary formulas that vary by employee type, client, and contract structure. The platform handles the full range of earnings and deductions in one payroll run.

Earnings Components
Basic, HRA, CCA, incentives, overtime pay, arrears, and bonus — each with configurable formulas per employee grade
Statutory Deductions
PF, ESIC, Professional Tax (state-specific), Labour Welfare Fund, and TDS — calculated and deducted automatically
Arrear Processing
PF arrear, salary arrear, and incentive arrear handling with retroactive calculation and payroll adjustment

Cross-Platform Mobile App for Employees and Supervisors

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

Authentication and Security
Mobile OTP Login
SMS-based verification for secure employee access
Biometric Security
Fingerprint and FaceID support after OTP verification
Aadhaar Verification
Aadhaar number and identity checked before app access is granted
Mandatory Document Upload
PAN card, police verification, and other required documents submitted in-app
A2Z Group mobile HR app login screen with OTP authentication
A2Z Group employee mobile app secure login interface
A2Z Group ERPNext HR mobile app employee login screen
Employee Self-Service Features

Payslip Download
View and download salary slips by month in web, mobile, and PDF formats — on demand, without contacting HR
Leave Management
Apply for leave and track approvals with real-time leave balance visibility against custom allocation rules per client
Attendance Regularization
Employees raise regularization requests for missed check-ins directly from the app; supervisors approve or reject in-app
3

Aadhaar-Based Employee Onboarding

Employees' Aadhaar numbers and supporting documents including Aadhaar card, PAN card, and police verification reports were validated by HR before app access was granted, ensuring a secure and verified onboarding process aligned with Indian compliance requirements.

4

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 and shift requirements.

5

Attendance-to-Payroll Pipeline and Geo-Fencing

Getting attendance data right is the upstream dependency for every payroll number. Auriga IT built the full pipeline — from geo-fenced check-in at each site through to final payroll processing — with conflict resolution logic and override controls that keep data clean at scale across 12,000+ employees.

Attendance Pipeline Flow
Geo-Fence Check-In
Location-verified entry at site boundary
→
OT Calculation
Overtime derived from actual hours and site data
→
Payroll Integration
OT and attendance feed automatically into payroll run
Attendance Data Sources and Conflict Resolution
Biometric Device Import
Attendance imported directly from biometric devices at sites where hardware is deployed
Mobile Geo-Fence Check-In
App-based location-verified check-in for sites without biometric hardware
Manual and System Override
Conflict resolution when biometric import, mobile check-in, and manually entered records differ — defined priority rules apply
Half-Day and LOP Logic
Half-day, late-in, and Loss of Pay scenarios computed automatically from shift rules; present overrides applied where eligible
6

Indian Statutory Compliance

Managing 12,000+ employees across multiple states means handling a different set of compliance rules per location. Auriga IT built each statutory requirement directly into the payroll engine rather than leaving it as a manual post-processing step, so contributions, challans, and reports are generated as a natural output of each payroll run.

Statutory Modules Configured
PF (Provident Fund)
Employer and employee PF contributions calculated per run; PF Challan generated for direct submission and PF Arrear Report for retroactive adjustments
ESIC
ESIC contribution calculated on applicable wages; ESIC subcodes configured per company entity; ESIC Report exported for challan filing
Professional Tax
State-specific PT slabs configured for each state A2Z operates in; deducted automatically based on employee location
Labour Welfare Fund
LWF deduction applied at the correct state frequency (monthly or half-yearly) per applicable state rules
Bonus
Statutory bonus computed in compliance with the Payment of Bonus Act; Bonus Report included in the payroll reporting suite
Salary Arrear Reporting
Salary Arrear Report generated for statutory filing when retroactive pay revisions affect prior periods
7

Multilingual Access and Client Ticketing Panel

The platform was designed to support multiple Indian languages, improving accessibility for employees across regions. A client-facing ticketing panel allowed attendance, payroll, and billing concerns to be raised directly for faster resolution across A2Z's 40+ client accounts.

8

Finance, Accounting, and Procurement Operations

Accounting ran on spreadsheets and Tally, GST was filed through a separate portal, and project-wise revenue and cost could not be traced without manual reconciliation across 100+ sites and 40+ clients.

Auriga IT centralized procurement, accounting, and financial reporting directly inside ERPNext, replacing the spreadsheet-and-Tally workflow with one connected system for capturing site-wise service requests, tracking purchase costs, reconciling bank transactions, and filing GST.

Procurement and Accounting Modules
Centralized Procurement
Service and material requests for housekeeping, electrical, and lift maintenance work captured directly against each client site, replacing manual spreadsheet tracking
Accounting Dimensions
Four dimensions, Project, Group, Zone, and Operating Personnel, break every transaction down by client contract, parent account, region, and manager
Purchase-Side GL Automation
Purchase entries post directly to the general ledger against equipment and material costs, with stock movement tracked in the same dashboard
Bank Reconciliation
Bank statement entries are matched against ERP payment entries, including cases where deductions or interest split one ERP entry across multiple bank-side entries
Project-Wise Revenue Tracking
Invoicing and payment are recorded against each project directly, so revenue and cost for any single project no longer needs to be reconstructed from spreadsheets
Address Auto-Fetch
Site addresses across 100+ locations are mapped once and auto-fetched onto every transaction, removing a manual entry step that previously allowed mismatched addresses
Statutory and Management Reporting
Trial Balance, Profit and Loss, and Balance Sheet reports are available on demand, alongside GST reports filed against A2Z's multiple state-wise GSTINs
Accounting Dimensions in Practice

Revenue and profitability can be filtered by any of the four dimensions on its own or combined, for example, checking a single zone's numbers, then narrowing further to one site within that zone, without rebuilding the report each time.

Project
Each client contract tracked as its own project for revenue and cost
Group
Clients with multiple sites or projects rolled up under one parent group
Zone
Regional grouping for territory-level revenue and cost views
Operating Personnel
Manager-wise profitability for personnel handling multiple projects

06 - Why This Case Matters

For Any Organization Managing a Large, Distributed Workforce

Any organization running facility management, security staffing, logistics, or field services at scale faces the same problem A2Z Group faced: off-the-shelf HR tools that don't fit real shift and site structures, no way to verify attendance without a supervisor physically present at every location, payroll that can't keep up with overtime calculated per site, compliance teams manually assembling PF Challans and ESIC reports from raw payroll data, and finance unable to trace revenue or cost back to a single project without reconciling spreadsheets by hand. Building geo-fencing, Aadhaar-based onboarding, multi-component payroll, Indian statutory compliance, mobile self-service, and accounting dimensions for project- and zone-wise financial visibility directly into one ERP platform — rather than bolting on separate point tools — lets workforce operations and finance scale together as headcount, site count, and client count grow.

07 - More ERPNext Work by Auriga IT

A2Z Group's HRMS runs on the same ERPNext and Frappe foundation Auriga IT uses across other large-scale implementations. For another look at how that foundation holds up at enterprise scale, see how Kapila Cattle Feed unified five manufacturing plants on one cloud ERP.

08 - Frequently Asked Questions

Questions About This ERPNext HR and Finance Project

What challenges did A2Z Group face with their existing HR and finance systems?

A2Z Group faced lack of customization in off-the-shelf HR tools, scalability and integration issues across 12,000+ employees and 100+ sites, limited digital access for employees who had to rely on calls and emails for HR queries, no multilingual support for a diverse regional workforce, and finance operations running on spreadsheets and Tally with no single system to trace project-wise revenue.

What HR, payroll, and finance solution did Auriga IT build for A2Z Group?

Auriga IT designed a tailored ERPNext and Frappe HR based system that included a centralized web HRMS platform, cross-platform mobile app with OTP and biometric login, Aadhaar-based onboarding, geo-fencing for attendance and overtime, a full attendance-to-payroll pipeline with conflict resolution, multi-component salary structures, Indian statutory compliance (PF, ESIC, PT, LWF, Bonus), payroll automation, roster management for distributed staff, multilingual support, a client-facing ticketing panel, and, on the finance side, centralized procurement, accounting dimensions, bank reconciliation, and statutory financial reporting.

What does the A2Z Group HRMS web platform include?

The HRMS covers company and client records, employee master data, attendance and shift management, leave policies, multi-component payroll processing with statutory deductions, employee promotions, and role-based permissions, alongside dedicated payroll, attendance and leave, and HR analytics reports, all managed from one ERPNext desk.

What features did the A2Z Group mobile HR app include?

The app included OTP login, biometric security using fingerprint and FaceID, Aadhaar verification, mandatory document upload, employee profile view, geo-fenced check-in and check-out, payslip download in web, mobile, and PDF formats, leave management with real-time leave balance visibility against custom allocation rules, and attendance regularization requests.

How did geo-fencing improve attendance and payroll?

Geo-fencing improved attendance accuracy by capturing location-verified check-ins across all sites. This data, combined with biometric device imports where available, fed into conflict resolution logic that resolves discrepancies between different attendance sources. Overtime was then calculated precisely from actual hours and location data, and flowed automatically into the payroll processing engine for accurate compensation.

How does the platform handle Indian statutory compliance?

Indian statutory compliance is built directly into the payroll engine rather than handled manually after each run. The platform automatically calculates PF and ESIC contributions, generates PF Challans and ESIC Reports for filing, applies state-specific Professional Tax slabs, handles Labour Welfare Fund deductions at the correct frequency per state, computes statutory bonus per the Payment of Bonus Act, and generates Salary Arrear Reports when retroactive pay revisions affect prior periods.

What technology stack was used for the A2Z HR platform?

The solution was built on ERPNext using Frappe HR and Payroll modules, supported by a cross-platform mobile app for Android and iOS, OTP and biometric authentication, Aadhaar verification workflows, geo-fencing based attendance logic, a multi-component payroll engine with Indian statutory compliance modules, and a multilingual interface for regional accessibility.

Can ERPNext handle HR and payroll for large Indian enterprises?

Yes. This case study demonstrates ERPNext and Frappe HR successfully managing 12,000+ employees across 100+ sites in India. The platform supports Aadhaar-based onboarding, multi-component salary structures, Indian statutory compliance (PF, ESIC, PT, LWF, Bonus), multi-site roster management, geo-fencing attendance with conflict resolution, and multilingual interfaces, making it a strong choice for large Indian enterprises with distributed workforces.

What finance and accounting capabilities were built into the A2Z Group ERPNext platform?

The platform centralizes procurement for site-wise service and material requests, replacing spreadsheets and Tally. Four accounting dimensions, Project, Group, Zone, and Operating Personnel, break every transaction down for site- and manager-wise reporting, purchase entries post automatically to the general ledger with stock tracking, bank statements are reconciled directly against ERP payment entries, and Trial Balance, Profit and Loss, Balance Sheet, and GST reports are generated on demand.

How does A2Z Group track project-wise revenue and manage GST across multiple states?

Invoicing and payment are recorded against each project directly, so revenue and cost for any single project, site, or zone are available from the accounting dimensions without manual reconciliation. GST reports are generated per A2Z's state-wise GSTINs directly inside ERPNext, replacing the earlier workflow of filing GST through a separate portal.
