Business Process Outsourcing (BPO) is the practice of contracting an external company to perform specific business functions — customer support, sales, collections, back-office work, or technical support — that were traditionally handled in-house.
BPO (Business Process Outsourcing) is the practice of hiring an external company to handle business functions that another company doesn't want to run in-house. When you call a bank's customer service number and an agent answers in a Bangalore contact center, that agent works for a BPO — the bank has outsourced its customer support function to that BPO.
BPOs have existed since the 1980s, but India became the global hub starting in the late 1990s when companies like Genpact, Wipro BPO, Infosys BPO, and TCS BPO scaled to handle outsourced work for Fortune 500 clients. Today the Indian BPO industry employs over 4 million people and generates $50B+ in annual revenue.
BPO stands for Business Process Outsourcing. Some adjacent acronyms cause confusion:
| Acronym | Full Form | Difference | |---|---|---| | BPO | Business Process Outsourcing | Outsourcing of business processes (broad) | | KPO | Knowledge Process Outsourcing | Higher-skill work: research, analytics, legal, financial | | ITES | IT-Enabled Services | Overlapping term often used in Indian regulation | | LPO | Legal Process Outsourcing | Specifically legal research, contract review | | RPO | Recruitment Process Outsourcing | Specifically hiring functions |
In simple words: BPO is the umbrella; KPO, LPO, RPO are higher-value subsets that require specialized knowledge.
BPOs typically handle one or more of these function categories:
Three main drivers:
India dominates the global BPO industry for several reasons:
Quality is the single biggest factor that separates winning BPOs from losing ones. Clients evaluate BPOs on:
Historically, BPO quality assurance was done by manually sampling 2-5% of calls — a process that scales poorly past 500 agents. Modern BPOs are shifting to AI-driven 100% audit coverage to deliver client-visible quality at scale.
In 2026, the BPOs winning new client RFPs are the ones that have already embedded AI in three places:
This shift is most visible in Indian BPOs working in regulated verticals — BFSI, Insurance, Healthcare, and EdTech — where client contracts increasingly require AI-monitored 100% audit coverage as a baseline.
Gistly is purpose-built for mid-market BPOs (200-500 agents) in India that need to deliver 100% audit coverage without enterprise-grade pricing or 4-6 week implementations.
The platform:

BPO (Business Process Outsourcing) is when one company pays another company to handle parts of its business — usually customer service, sales, or back-office work. When you call a bank's helpline and someone answers in a different city or country, you're probably talking to a BPO agent.
BPO covers any business process outsourcing — typically customer service, sales, or back-office work. KPO (Knowledge Process Outsourcing) is a higher-skill subset: research, analytics, legal work, financial analysis. KPOs hire more domain experts; BPOs hire more agents.
Five reasons: large English-speaking workforce, time zone alignment with Western clients for night shifts, established BPO ecosystems in major cities, cost advantage over US/UK labor, and multilingual capability for serving global brands.
AI is being embedded in three places: real-time agent assist (reducing AHT), AI-driven QA (replacing manual sampling), and compliance monitoring (catching violations in real time). The BPOs winning new RFPs in 2026 already have AI in all three layers.
