Payroll Management System

A payroll solution integrated with biometric attendance and automated salary payouts.

Chapter 02

The Story

Attendance was tracked on a biometric machine that never talked to payroll — every salary run meant manually cross-referencing punch logs. I connected the biometric device directly into payroll processing, with salary payouts automated through Cashfree.

By linking hardware registers directly to calculation databases, manual ledger entry errors dropped to zero. Authorized salary payments route securely through API nodes, updating sheets instantly.

How It Was Built

Technical Approach

The system connects local biometric hardware registers to a centralized SQL ledger. Cashfree APIs are mapped with transactional check constraints to process direct-to-bank payroll disbursements securely.

Employee Profiles

Staff registry mapping roles, structural details, and customized wage categories.

Biometric punch sync

Syncs fingerprint and face registries directly to active attendance logs.

Payroll Computation

Calculates monthly wages, incentives, and attendance bonuses automatically.

Cashfree Payouts

Automated API node dispersing payouts directly to employee bank routes on payroll approval.

Payout Status Checks

Ledger tracking transaction results and triggering automatic retry pipelines on API failures.

Operational Reports

Consolidated month-end workforce costs, attendance graphs, and bank transaction audits.

The Challenge

"Syncing local biometric hardware registers into the cloud payroll system and securely handling Cashfree payout failures was the core challenge."

Because biometric attendance data formats differ across local machines and network connections can drop unpredictably, cross-referencing punch sheets manually was slow.

To solve this, I designed a buffer sync agent. The local agent fetches hardware records, formatting shifts to post to cloud payroll ledgers while maintaining retry queues to reconcile Cashfree payout API statuses safely.
