PROJECTHR, Payroll & Attendance Management for Indian SMEs
RATIONALEIndia has 63M+ SMEs, most running payroll on Excel. A SaaS at ₹199/employee/month that handles PF, ESI, PT, TDS and generates Form 16 automatically has an instant ROI story. NestJS cleanly separates payroll computation (deterministic, testable) from the API layer. PostgreSQL handles the relational structure of employees, components and pay periods well. PDF generation is server-side to avoid browser print inconsistencies.

⚠ RISK FLAGS
!Indian statutory rules (PF slabs, ESI threshold, PT state-wise) change yearly — externalise the tax rule engine so updates need no code deployment.
!Form 16 generation is legally sensitive; get a chartered accountant to review the computation logic before launch.
!Payroll is a zero-tolerance domain; write exhaustive unit tests for every computation path before going live.
