With India being a favoured market world over for back office support services by Business Process Outsourcing (BPO) and Knowledge Process Outsourcing (KPO) businesses, the segment has grown by leaps and bound from the time of its inception in the mid-90s. There are several factors which have cumulatively contributed to this growth such as economy of scale, cost advantage and technical competency. One contributing factor is also the tax benefits enjoyed by the sector owing to such operations being zero rated under GST as export of service.
