Overview

W2S HRM was built to unify HR operations into a single intuitive system, enabling teams to manage hiring, employee records, shift patterns, leave tracking, attendance, payroll processing, and exit formalities with accuracy and compliance.

The Payroll module automates salary processing, tax deductions, pay slip generation, and biometric syncing to ensure precision and efficiency in every pay cycle.
