Today,BPO industry is the fastest growing segment of the ITES (Information Technology Enabled Services). Factors such as economy of scale, cost advantage, utilization improvement and higher competency level have all lead to the growth of the Indian BPO industry an it is now growing by leaps and bounds.

Now-a-days India is the world's favored market for BPO companies, in comparison to other competitors, such as, Australia, China, Philippines and Ireland. This BPO boom in India is due to cheap labor costs and India's huge talent pool of skilled, English-speaking professionals. Research by the National Association of Software Services and Companies (NASSCOM) has revealed that quality orientation among leading BPO companies, 24/7 services, India's unique geographic location and the investor friendly tax structure have all made the BPO industry very popular.

Indian BPO companies offer varied services, such as, customer support (24/7 inbound / outbound call center services that address customer queries and concerns through phone, email and live chat),
Technical support (Interacting with potential customers and creating interest for the customer's services/ products. Up-selling, promoting and cross selling to existing customers and completing online sales processes), Telemarketing (Interacting with potential customers and creating interest for the customer's services/ products. Up-selling, promoting and cross selling to existing customers and completing online sales processes), Insurance processing (New business acquisition and promotion, claims processing, policy maintenance and policy management), Data processing ( Data entry from paper, books, images, e-books, yellow pages, web sites, business cards, printed documents, software applications, receipts, bills, catalogs and mailing lists), Forms processing, Bookkeeping (Maintenance of the customer's general ledger, accounts receivables, Accounts payable, financial statements, bank reconciliations and assets / equipment ledgers) and Internet / online / web research (Internet search, product research, market research, surveys, analysis, web research and mailing list research)

A BPO service provider usually administers and manages a particular business process for another company. BPOs either use new technology or apply an existing technology in a new way to improve a particular business process. India is currently the number one destination for business process outsourcing, as most companies in the US and UK outsource IT-related business processes to Indian service providers.
