The system helps address gaps in trade-in-services data, particularly in developing countries, and supports evidence- based policymaking. TiSSTAT is built on a Microsoft SQL RDBMS architecture and developed using Java with Spring Boot. The front-end/user interface is developed using the Angular JavaScript framework. TiSSTAT is currently available in English and French, with plans to expand to Arabic, Russian, and Spanish, while allowing questionnaires to be adapted to the language needs of end-user countries. The aim is to etablish a multi-year contract for an initial period of three (3) years with the option to extend for one (1) additional two (2) years period (3+2) at the sole discretion of UNCTAD.
