Testimonial from Client?

QSoft Vietnam is an absolute pleasure to work with. They promptly did exactly as instructed, demonstrated an agile and smart approach to their designs and made multiple changes in no time. We thus, never fell behind the schedule in any stage of project revolution and were well assured of the satisfiable work quality. All individuals I worked with were very friendly, professional and spoke excellent English. Another selling point that deeply impressed me is QSoft Vietnam's charging policy. The outsourcing rate given by QSoft Vietnam is very competitive. We will definitely hire them again and again.
