A professional outsourced payroll provider is a company that manages all payroll-related functions for other businesses. They handle tasks such as calculating employee wages, processing tax deductions, ensuring compliance with local and federal regulations, issuing payments, and generating pay stubs. Outsourcing payroll helps businesses save time, reduce the risk of errors, and avoid legal issues related to tax filings or labor laws. These providers often offer additional services like benefits administration, time and attendance tracking, and HR support, allowing companies to focus on their core business operations.
