'In this business, it's easy to make big mistakes. We don't really need investors right now; our focus is still on providing honest-to-goodness service. We don't need to keep up with them,' said Raffy David, Pilipinas Teleserv's director for marketing and quality assurance, referring to other operators that continue to expand and ride on the call center boom in the Philippines.

Since it started in 2000, Pilipinas Teleserv has built a successful and sustainable business from providing 24/7 call center support and delivery services to the Department of Foreign Affairs and the National Statistics Office -- the former for passport renewal and the latter for procurement of legal documents such as birth certificates.

The company also launched last November a one-stop clearance service for the Philippine Overseas Employment Agency (POEA), which is meant for 'balikbayan' Filipino overseas contract workers. In 2002, Pilipinas Teleserv branched out into providing call center support for delivery services of local food chains McDonald's, Max's Fried Chicken, and Super Bowl of China.

This year, David said the company will focus on its recent expansion into third-party verification or TPV services.
