Apex Enterprise HR & Payroll Automation Portal
Streamlining biometric attendance, statutory tax compliance, and payroll for 1,800+ distributed enterprise employees.
How did NiyajTech automate enterprise payroll and biometric attendance?
NiyajTech developed a custom FastAPI and React enterprise HRM system integrated with on-premise biometric hardware across 6 corporate facilities. The platform automated statutory tax calculations (PF, ESI, TDS) and reduced 5-day payroll processing to under 4 minutes.
- Automated real-time biometric hardware sync eliminated manual CSV errors.
- One-click payroll engine generated 1,800+ salary slips in under 4 minutes.
- 100% compliance with Indian statutory payroll taxes (TDS, PF, ESI).
- Slack-integrated approvals accelerated leave processing by 92%.
The Transformation at a Glance
Engineered an enterprise-grade HRM and payroll software that connects biometric hardware across 6 regional warehouses with an automated salary calculation engine, reducing payroll processing from 5 days to under 4 minutes with 100% tax compliance.
Core Challenges & Bottlenecks
Before partnering with NiyajTech, the client faced significant operational hurdles that directly limited business growth and customer satisfaction.
Manual Biometric Excel Downloads Across 6 Regional Sites
Attendance data was trapped in standalone biometric hardware machines across Delhi, Noida, and Mumbai warehouses. HR spent the first week of every month manually merging corrupted CSV files.
Complex Indian Statutory Tax Computations (PF, ESI, TDS, PT)
Errors in overtime calculations, tax slab exemptions, and varying state professional taxes triggered frequent employee salary disputes and delayed compliance filings.
Opaque Employee Appraisal & Leave Approval Delays
Leave applications submitted over email took days for multi-level managers to approve, leaving shift planners blind to warehouse staffing shortfalls.
The Technical Architecture & Solution
NiyajTech engineered a scalable, clean-code architecture prioritizing sub-second speed, high availability, and automated workflows.
Real-Time Biometric Hardware IoT Webhook Ingestion
Created automated bridge software connecting on-premise biometric fingerprint/face scanners to a secure cloud API, updating attendance logs instantaneously.
One-Click Automated Payroll Engine with Encrypted PDF Slips
Developed a rule-based calculation engine covering PF, ESI, TDS regimes, and overtime multipliers. Generates password-protected salary PDFs dispatched automatically to employee emails and WhatsApp.
Slack & Web App Workflow for Instant Manager Approvals
Integrated Slack interactive webhook buttons and a responsive web dashboard allowing managers to approve leaves and shift swaps in under 10 seconds.
