One system for biometric attendance, statutory payroll and the paperwork around both — so the hours on the register, the days on the muster and the money on the payslip are the same figures, worked out once.
Biometric devices sync on their own. Night shifts, rotating rosters and each employee's own weekly off are resolved per person per date — not assumed from a calendar.
PF, ESI, LWF, bonus and gratuity worked out per employee, with the registers, Form C and payslips that go with them.
Request, approve, cap. Hours past the statutory monthly cap move onto their own incentive line instead of quietly inflating the wage.
Accrual, register, encashment — and a balance the payslip agrees with, because both read the same figures.
Staff mark attendance, request leave and read payslips from the app; a gate kiosk covers everyone who does not carry one.
Every edit is recorded with who made it and when, and a month that has been audited can be frozen so even a super-admin cannot alter it.
