Headquartered in Hanoi, Vietnam, Add-On Development (AOD) currently maintains a group of certified and experienced developers. Today, as a Microsoft Gold Certified Partner, we perform software development for clients worldwide. In Europe, AOD has sales offices in Utrecht, the Netherlands, and Vejle, Denmark; and across the Atlantic, we have an office in Toronto, Canada. Furthermore, we staff Project Managers in a number of other locations scattered around the world. Formed on February 29, 2008, as a joint venture between VietSoftware International and Add-On Products (AOP), AOD was set up to specialize in the development of high-quality software based on Microsoft technologies. Initially, development of AOP software projects was transferred from other areas of the world to AOD in Hanoi. In doing so, our efforts were mainly focused on optimizing our hardware and software infrastructure and on developing efficient business routines. In this process, our certifications were obtained and best practices were established. We also developed our abilities in overcoming cultural barriers, which is a key to successful project completion across continents. AOD is characterized by being flat, dynamic, flexible, and project oriented. While applying efficient processes, the newest technology and modern means of communication, only a few staff members are devoted to administrative duties.
