PayslipPro – Smart Payroll Automation

Inspiration

Managing payroll manually is painful—especially for small HR teams juggling spreadsheets, emails, and last-minute salary slip corrections. We built PayslipPro to eliminate that chaos.

What It Does

PayslipPro automates salary generation, attendance tracking, earnings & deductions configuration, and one-click payslip distribution—while keeping everything structured around your organization.

HR admins can:

• Add or import employee details (with optional previous company docs)
• Configure salary components (earnings/deductions)
• Track attendance manually or monthly
• Generate & email branded payslips with a single click
• View logs and delivery status in real-time

How We Built It

We designed and developed the platform using:

• PostgreSQL for relational data modeling
• Node.js (Express) backend with REST APIs
• React (Next.js) frontend with Tailwind for UI
• HTML2PDF.app for generating professional-grade payslip PDFs
• AWS S3 for file storage (uploads, profile photos, documents)
• Email SMTP integrations for bulk payslip distribution

Challenges Faced

• Structuring JSON salary components dynamically to allow customization
• Designing a multi-step employee onboarding UX flow with validations
• Building an instant department/position creation from dropdown
• Handling large PDF generation queues during peak processing
• Ensuring data consistency across attendance & payroll modules

What We Learned

• How to build modular backend APIs that scale with organizational growth
• UX thinking behind HR admin workflows (from user interviews)
• How to handle real-world PDF generation at scale with API keys
• How to create reusable component logic for multi-tab forms
