HR & Payroll System
Complete HR management system with payroll processing, leave management, performance reviews, and automated PDF salary slip generation.
Overview
Modules include: employee profile with documents, department and designation hierarchy, shift management, attendance via biometric device import, monthly payroll with allowances/deductions/overtime/bonus, income tax calculation as per Bangladesh tax slab, leave management with approval workflow, performance appraisal, and automated salary slip PDF email.
Problem
The company was using Excel sheets for payroll and had 3 HR staff spending a full week each month just calculating salaries. Tax calculations were error-prone and salary slips were printed and physically distributed, costing paper and time.
Solution
Built an automated payroll engine that processes 800+ employee salaries in under 2 minutes using batch processing. DomPDF generates individualized salary slip PDFs which are emailed automatically via job queue. A tax engine applies the current Bangladesh income tax slabs and generates annual tax certificates.
Outcomes
- Payroll processing time: 4 days → 2 minutes
- Zero calculation errors since deployment
- HR team saves 40 hours/month
- Tax certificates auto-generated annually
