The Administrative Bottleneck

Why Growing Organizations Are Trapped Between Painful Spreadsheets and Costly Per-Seat HR SaaS

Managing workforce operations through manual Excel spreadsheets and paper leave slips leads to inevitable payroll calculation errors, delayed salary disbursements, inaccurate tax deductions, and statutory compliance penalties from EPFO and ESIC authorities.

However, subscribing to commercial HR platforms like Keka, Darwinbox, or GreytHR subjects companies to recurring per-employee monthly licensing fees (₹50 – ₹250/employee/month). As hiring expands, annual software expenses escalate drastically, while rigid policy rules prevent you from customizing shift rotations, unique overtime matrices, or specialized incentive formulas.

System Architecture

Statutory Compliance Logic, Biometric Sockets & Salary Encryption

Engineering a high-compliance human resource system requires solving stringent statutory rules, hardware latency, and sensitive compensation confidentiality:

1. Statutory Tax Computation Engine (Old vs. New Tax Regime)

Our calculation engine runs dual-regime tax simulations for every employee in real-time. It accounts for Section 80C deductions, 80D medical insurance, HRA exemption (least of rent paid over 10% salary, actual HRA, or 50%/40% of basic), standard deduction (₹75,000 under new regime), and marginal tax relief, automatically computing monthly TDS deductions with zero human error.

2. Asynchronous Biometric Device Push Listeners

When thousands of employees punch simultaneously during shift changeovers, direct database writes cause deadlocks. We run asynchronous TCP socket listeners that ingest raw hardware punches into Redis in-memory streams, automatically calculating punch intervals, night-shift spans, and late penalties in decoupled background workers.

3. Cryptographic Salary Vault (AES-256)

To protect sensitive executive compensation and bank account details from internal IT leaks, all financial columns in the database are encrypted at rest using envelope encryption (AES-256-GCM) with separate cryptographic keys managed through AWS KMS or HashiCorp Vault.

FAQ Guide

Frequently Asked Questions on Custom HRM Software Development

Why build a custom HRM software instead of subscribing to Keka, Darwinbox, or GreytHR?
Commercial SaaS HRMS platforms charge recurring monthly per-employee licensing fees (₹50 to ₹250/employee/month). As your team grows to 100, 500, or 2,000+ employees, your software costs multiply exponentially every year. A CodTeg Custom HRM is built 100% for your organization's exact hierarchy, shift rules, and appraisal cycles. You pay zero recurring per-employee license fees, gain unlimited staff accounts, self-host on private cloud/on-premise servers, and retain full IP and source code ownership.
How does biometric hardware (ZKTeco, Essl, Matrix) integrate with the custom HRM?
We connect directly with your biometric fingerprint, facial recognition, and RFID card hardware via automated TCP/IP push protocols and REST APIs. Inbound punch logs from all branch offices and manufacturing plants are ingested in real-time into the central cloud database, calculating overtime, late arrivals, half-days, and shift allowances automatically.
Does the payroll system automatically handle Indian statutory compliances like PF, ESI, PT, and TDS?
Yes. Our payroll calculation core is 100% compliant with Indian tax and labor laws. It automates Provident Fund (EPF/EPS with wage ceilings), Employee State Insurance (ESIC), state-specific Professional Tax (PT), Labour Welfare Fund (LWF), and Section 192 Income Tax (TDS) under both Old and New Tax Regimes, generating ready-to-upload EPFO ECR text files, ESIC monthly returns, and Form 16 Part A & B.
How does mobile attendance work for remote or field sales employees?
We provide cross-platform Employee Self-Service (ESS) mobile apps (iOS & Android) equipped with GPS geo-fencing and optional AI facial liveness verification. Field sales reps or remote employees can clock in only when within designated client coordinates, preventing proxy attendance with complete location telemetry.
How is confidential salary and employee personal data protected?
We implement enterprise-grade security including AES-256 field-level encryption on salary structures, bank account numbers, and Aadhaar/PAN details. Database access is strictly governed by Row-Level Security (RLS) and Role-Based Access Control (RBAC), ensuring department managers only see approved performance data while executive compensation remains restricted exclusively to authorized HR leadership.
Can you migrate our historical employee data, leave balances, and past payroll records?
Yes. We execute a seamless ETL data migration from Excel spreadsheets, legacy HR software, or biometric device databases. We map employee master profiles, active leave balances, historical salary slips, and tax investment declarations with 100% data validation before going live.
Can the custom HRM connect directly with corporate bank accounts for 1-click salary disbursement?
Yes. We integrate secure corporate banking payout APIs (ICICI Corporate Banking, HDFC Enet, RazorpayX, or Axis Bank) or generate standardized encrypted bank payout text/Excel files for bulk NEFT/RTGS salary disbursements with a single approval click.
