Experimental evaluation demonstrates a reduction in payroll processing time by approximately 78%, elimination of manual compliance errors, and improved resource utilisation through data-driven allocation decisions. is designed to serve organisations with 50 to 10,000 employees, making it suitable for both growing enterprises and large-scale corporations.
