Business process outsourcing (BPO) involves entrusting a
variety of business functions to external service providers, allowing companies to focus on their core operations. BPO is divided into two types: front-office and back-office outsourcing. Front-office outsourcing encompasses jobs that require direct interaction with customers, such as marketing, advertising, and assisting customers with difficulties. On the one hand, back-office outsourcing includes jobs that happen behind the scenes — examples include handling computer systems, managing finances, and personal management.
