ERP payroll

I am in need of an ERP payroll system for my large sized business which includes more than 200 employees. My main focus is automated calculations for any payroll processing, and so I’m hoping to find a system that can easily integrate automated payroll calculations into my existing workflow. Additionally, I would prefer if the system has the ability to customize deductions for employees, as well as integrated time and attendance features. If you have a system that can meet these requirements, please send in any relevant proposals. Thank you for your time.
