BPOs are also appointing domain specialists to improve their verticalized offerings. For instance, banking sector executives are hired to work on actuarial (risk assessment) roles at BPOs.

The BPO vertical focus is similar to what IT companies are doing. TJ Singh, research director at Gartner, however said that unlike IT companies, Indian BPOs have not appointed vertical heads or made major managerial changes. BPOs add vertical expertise by either making acquisitions or setting up bases in countries where a particular expertise exists. On May 2, BPO firm EXL Service Holdings acquired finance and accounting outsourcing service provider Outsource Partners International, deepening EXL's expertise in this space.

Others like Tech Mahindra , TCS and Aegis are also scouting for acquisitions in different geographies. Some Eastern European countries are excellent for accounting, while the US is good for healthcare experts.
