UK-based BPO firm Vertex on Tuesday said it will increase its headcount in the country to 20,000 employees over the next two years as it ramps up its operations in India.

The Vertex group, which had acquired domestic player Shell Transource last year, has about 6,000 people on its payroll (post-acquisition).

"The acquisition has helped Vertex emerge as a significant player in the domestic market. Going ahead, we have major expansion plans as part of which we will have 11,000-13,000 people by September next year," Vertex Group CEO Paul Sweeny told reporters here.

This will be increased to 20,000 people by September 2013, he added.

Vertex also expects its revenues from India to cross USD 100 million (about Rs 450 crore) by end of 2013, but Sweeny declined to comment on the current revenue figures.

"Over the last six months, we have had significant growth with nine big wins, which includes three of the top five telecom majors in India," Vertex India MD and CEO Keshav Gaur said.

He added that the clients spanned sectors like telecom, financial services, utilities, government, FMCG and retail.

In the government vertical, the company has been empanelled by the Unique Identification Authority of India (UIDAI) for enrolling people, apart from contracts from the tax department and utility companies.

Talking about the business opportunuties here, Sweeny said, "There is a huge potential in the domestic sector. The growth rate here is better than other counutries".

He added that the domestic market for BPOs has grown at a compounded annual growth rate of 35 per cent.

"New sectors like retail, media and DTH will drive the growth further and these factors will help boost our confidence in the Indian market," Gaur said.
