BPOSeats provides seat leasing and serviced offices in the Philippines for companies based overseas. We have over 14,000 seats across our locations, and we have been doing this since 2014. Here is how it works. You bring the team and manage the work. We provide the workstation, computer, dual fiber internet, backup power, air conditioning, IT support, security, and 24/7 access. Your office belongs to your company alone. We do not put you on a shared floor with other businesses. If you do not have a registered company in the Philippines, we can employ your staff for you through our Employer of Record service, so you can hire here without setting up a legal entity. We can also help you recruit, and you make the hiring decisions. We work with businesses in the United States, Australia, the United Kingdom, Canada, and New Zealand. Most need between 10 and 50 seats, though we start at 4 and go up to 200. Our clients typically run customer support, technical support, back office, sales, or admin teams. We are a good fit if you want your own office and your own people in the Philippines, with the building and infrastructure handled for you. We are not a managed BPO, so if you want another company to run the work itself, we are not the right choice.

Genpact, a digital business process management and services provider, started off in 1997 as a business unit of General Electric. In 2005 it became an independent unit to serve clients beyond GE and in 2007 became a publicly traded company. In a matter of two decades, it grew in leaps and bounds. In 2005 they had 19000+ employees. December 2016 that number stood at 77000+ with important offices in New York City, Palo Alto, London, and Delhi. They have keyed the word Lean Digital which integrates lean principles (creating value for customers with limited resources), design conceptualization, analytics and digital technologies with their domain and their extensive knowledge of the industry. Their service comes broadly in two forms: domain enabled solutions and digital operations. Their experience at GE has helped develop a culture that focuses on customers’ needs and requirements, teamwork and the striving for continuous improvement. This is what they believe led to them having a 90% + contract renewal rate. Their services range from customer service to finance and accounting to collections, IT managed services, application services to procurement. The industries covered by them are equally varied. Present in 23 countries across all continents, they believe they are generating impact for companies. In two decades there’s been no looking back and they believe, rightly, that they have changed the definition of business process service.
