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.

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.

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.
