Build a Salary Slip Generator App

Create an easy-to-use mobile app that helps HR teams or freelancers generate structured monthly payslips based on salary components and download them as PDFs—perfect for fintech or HR utility app development.

Why Build a Salary Slip Generator App?

Small companies and freelancers often lack complex payroll software. A lightweight, mobile-first app that lets users generate PDF-based salary slips can be a huge time saver. This project teaches you form logic, PDF generation, conditional formatting, and structured document design in app development.

Core Features of the Payslip App

Let users enter employee details, salary structure (basic, HRA, allowances, deductions), and pay period. Automatically generate a formatted salary slip with gross and net pay calculations, downloadable as a professional PDF.

Key Features to Implement

Employee & Salary Input Form

Users can add employee name, ID, department, pay month, and detailed salary breakdown (earnings/deductions).

Dynamic Payslip Calculation

Automatically compute gross and net salary based on earnings and deductions, with tax and PF/ESI if applicable.

PDF Payslip Export

Generate and download printable PDF salary slips with branding, headers, and breakdown tables.

Payslip History & Templates

Save generated slips for reuse and allow exporting previous records for audit or printing.

How the App Works

The user starts by entering company and employee details, followed by the salary components. The app calculates totals automatically and formats the output as a PDF document that can be downloaded or emailed directly. Monthly payslips can be stored for reference or batch export.

  • Fill in employee and company information including job title, ID, and department.
  • Enter basic pay, HRA, bonuses, deductions, and taxes for the current month.
  • App computes net salary and generates a structured salary slip.
  • Download slip as PDF or share via email instantly.
  • View or reuse previous records through the payslip archive/history.
