The challenge

KOBI Education was managing employee payroll entirely through manual spreadsheets — spending days each month on calculations plagued by errors, missed deductions, and no audit trail.

  • Multi-day payroll processing with frequent human calculation errors
  • No centralized employee records or payroll history
  • Attendance tracking disconnected from salary calculations
  • No automated reporting, approvals, or audit logs
What we built

We built a full-stack MERN Payroll Management System that automated the entire payroll lifecycle — from attendance capture through salary calculation to one-click payslip generation.

  • Automated payroll engine handling deductions, allowances, and tax calculations
  • Attendance and leave tracking integrated directly into pay runs
  • One-click downloadable salary slips via PDF generation
  • Role-based admin dashboard with multi-level approval workflow
  • Full audit log and monthly reporting system
