Overview

WrenchWorks is a manufacturing enterprise with staff spread across several facilities in different states, running payroll manually in spreadsheets. We built an HRMS covering attendance, leave management, and multi-state payroll processing.

The Challenge

Payroll calculations varied by state compliance rules and were done manually each cycle, attendance was tracked via biometric devices with no central rollup, and leave requests were approved over email with no audit trail.

The Solution

We built an HRMS that ingests biometric attendance data centrally, applies state-specific payroll rules automatically, and routes leave requests through an auditable approval workflow. Payroll runs generate compliant payslips and statutory reports per facility.

Key Features

  • Centralized biometric attendance ingestion across facilities
  • State-specific automated payroll rule engine
  • Auditable leave request and approval workflow
  • Automated statutory report generation per facility
  • Employee self-service portal for payslips and leave balances
  • Role-based HR admin console for multi-facility management

Results

  • Eliminated manual payroll calculation errors across states
  • Centralized attendance data previously siloed per facility
  • Reduced HR staff time spent on leave approval administration
  • Improved statutory compliance reporting turnaround
