What is BPO? (Business Process Outsourcing)
BPO (Business Process Outsourcing) is the practice of contracting a specific business process to an external provider. Common BPO functions include customer support, payroll, finance and accounting, HR, and data entry. The provider delivers the outcome; the client pays a fixed or per-transaction fee.
In more detail
In a BPO arrangement, the client hands over an entire process (not just people) to a vendor. The vendor owns the workflow, the tools, the quality controls, and the workforce. The client specifies the outcome and SLAs (service level agreements), then receives regular reports on performance. BPO is most common in functions where a process is highly repeatable and where scale, standardization, or labor arbitrage create meaningful savings.
BPO grew rapidly starting in the 1990s as companies moved back-office work to India, the Philippines, and Eastern Europe. Today it spans everything from 24-hour customer contact centers to legal research, medical coding, and AI data labeling.
How BPO works
- Client and vendor define scope, SLAs, and pricing (fixed, per-transaction, or FTE-based).
- Vendor hires, trains, and manages the team on its own infrastructure.
- Vendor executes the process and reports against agreed metrics.
- Client audits quality and adjusts scope over time.
Front-office vs back-office BPO
- Front-office: customer support, telesales, lead qualification, live chat.
- Back-office: payroll, bookkeeping, AP/AR, HR administration, claims processing, data entry.

Common follow-up questions
BPO buys an outcome, such as calls answered or invoices processed. Staffing buys a person's time, where the client directs the work. BPO providers own the process and the people; staffing providers place people the client directs.
Front-office BPO covers customer-facing work such as contact centers and sales support. Back-office BPO covers internal operations such as payroll, HR, finance, and data processing.
No. BPO is about delegating a process. Offshoring is about where the work happens. BPO can be onshore, nearshore, or offshore.
