This project covered the design and development of the BOI Online Services System (BOSS) consisting of 3 major information systems, as follows: 1) Registration Information System, 2) Information System and 3) Compliance Information System. The BOSS aims to provide BOI the technical capability to handle the volume of transactions required to fulfill its mandate and deliver the services that the agency provides to its stakeholders and the public in general. Moreover, the agency also sought to enhance its Investment Leads Monitoring System (ILMS) and strengthen its capability to manage and process data and information crucial to boosting investment promotions for the country.
