A BPO (Business Process Outsourcing) company is a third-party service provider that handles another companys business processes, functions, or operations. BPO is a method of subcontracting various business-related operations to third-party vendors. BPO companies can provide support for standard business functions such as customer service, accounting, payroll, and human resources management. BPO call centers are teams of outsourced agents who handle incoming and outgoing customer calls for other businesses. Companies benefit from BPO by achieving more flexibility and cost efficiency. By outsourcing a dedicated task such as payroll to a specialized BPO company, they may make cost savings that can be passed on to clients. BPO is an industry unto itself, with companies specializing in facilitating BPO to companies around the world.
