BPO, or business process outsourcing, is the practice of contracting a specific business function — such as customer support, payroll, finance, or data processing — to an external provider rather than running it in house. The provider delivers the work to an agreed standard and service level, usually to reduce cost, access specialist skills, or scale a team faster than in-house hiring allows.
This guide defines BPO, sets out its main types, explains the onshore/nearshore/offshore models, and shows how it relates to KPO and IT outsourcing — then points to where to go deeper on choosing a destination.

Key terms
- Back-office BPO
- Internal-facing functions outsourced to a provider — finance and accounting, HR, payroll, data entry and processing.
- Front-office BPO
- Customer-facing functions — contact-centre support, sales, and customer experience.
- KPO (knowledge process outsourcing)
- A higher-skill branch of outsourcing covering judgement-based work such as research, legal and financial analysis.
What BPO actually means
Answer: BPO is delegating an ongoing business process to a third party that runs it for you to an agreed standard.
The key word is process. Rather than outsourcing a one-off project, a company hands over the continuous running of a function — answering customer queries, processing invoices, moderating content — to a provider who staffs, manages and delivers it. The client keeps control of strategy and direction; the provider supplies the people, tools and day-to-day management. Pricing is typically per seat, per hour, per transaction, or as a managed monthly fee.
The main types of BPO
Answer: BPO is categorised two ways — by function (back-office vs front-office) and by location (onshore, nearshore, offshore).
By function:
- Back-office — finance and accounting, HR, payroll, procurement, and data processing.
- Front-office — customer support, technical helpdesk, sales and customer experience.
By location:
| Model | Where | Trade-off |
|---|---|---|
| Onshore | Same country | Highest cost; no language/time-zone gap |
| Nearshore | A nearby country | Moderate cost; small time-zone gap |
| Offshore | A distant, lower-cost country | Lowest cost; larger time-zone/cultural gap |
Most cost-driven outsourcing is offshore. The trade-offs that matter when choosing an offshore destination — time-zone overlap, English proficiency, legal compatibility and cost — are exactly what our Kenya outsourcing pillar guide examines for one specific destination.
Why companies use BPO
Answer: The four classic drivers are cost, skills, scale and focus — with time-zone coverage a frequent fifth.
Outsourcing a function to a lower-cost country can cut the fully-loaded cost of a role substantially; for example, KenInvest benchmarks a fully-loaded Kenyan contact-centre seat at USD 870-1,160 a month against USD 3,770-5,290 in the UK and USD 4,920-6,890 in the US. Beyond cost, BPO gives access to skills that are scarce or expensive at home, lets a team scale up or down quickly, and frees internal staff for core work. For global operations, a provider in another time zone can extend coverage toward 24-hour service. Our cost of outsourcing overview breaks the economics down in detail.
BPO vs KPO vs ITO
Answer: BPO covers operational processes; KPO covers high-skill knowledge work; ITO covers software and IT.
The three overlap but signal different value. BPO is the broad term for operational processes. KPO — knowledge process outsourcing — covers analytical, judgement-based work like research, legal review and financial analysis, where the provider’s expertise (not just labour cost) is the point. ITO (IT outsourcing) covers software development and infrastructure. A single destination can serve all three: Kenya, for instance, supports front-office customer support, back-office finance and accounting outsourcing, and KPO-style legal and data work.
How to choose a BPO destination
Answer: Weigh time-zone overlap, English proficiency, legal/data-protection fit, talent depth and total cost — not headline salary alone.
The right destination depends on the function and the buyer’s home market. For UK and European buyers, time-zone overlap and English proficiency favour African and some Asian hubs; for US buyers, after-hours coverage and cost often matter more than real-time overlap. Comparing destinations side by side is the practical way to decide — see Kenya vs India and Kenya vs the Philippines for worked comparisons, and the Kenya BPO industry overview for one destination in depth.
Key Takeaways
- BPO is contracting an ongoing business function to an external provider, priced per seat, hour, transaction or managed fee.
- It splits by function (back-office vs front-office) and by location (onshore, nearshore, offshore).
- The drivers are cost, skills, scale, focus and time-zone coverage; KPO and ITO are specialised branches.
- The global market is ~USD 194 billion by 2025, with Africa projected to triple to ~USD 20 billion by 2030.

What are the main types of BPO?
By function, back-office (finance, HR, data) and front-office (customer-facing). By location, onshore (same country), nearshore (a nearby country) or offshore (a distant, lower-cost country). Knowledge-intensive work is often called KPO.
Why do companies use BPO?
Cost reduction, access to scarce or expensive skills, the ability to scale quickly, freeing internal staff to focus on core work, and extended time-zone coverage.
What is the difference between BPO, KPO and ITO?
BPO covers operational business processes; KPO covers higher-skill, judgement-based work (research, legal and financial analysis); ITO covers software development and IT infrastructure.
How big is the BPO industry?
The global BPO market is estimated at around USD 194 billion by 2025 (KenInvest, citing Gartner and Everest). Africa’s market is projected to roughly triple from USD 8 billion in 2023 to USD 20 billion by 2030.
