Around the world, many countries are progressively implementing information systems that exchanges electronic information for work efficiency and information exchange standardization. However, Panama Canal faced difficulties in introducing the Canal Single Window because few practical guidelines and technical specifications exist. In full recognition of the absence of Single Window guidelines for maritime transport, the Panama Canal defined its own formats and standardization and implemented the first Canal Single Window in the year 2004 to declare all formalities and requirements to the Panama Canal. From there on, the Panama Canal made many upgrades to the system based on business changes. By the year 2015 the Panama Canal implemented a whole new Canal Single Window, including changes to the infrastructure and development tools. Furthermore, the Republic of Panama, as OMI member state, was called to facilitate the reporting formalities in electronic format via single window, among other challenges in the Logistic Sector. Therefore, Panama decided to re-used the current Canal Single Window and upgrade it to the Maritime Single Window of Panama (VUMPA). The VUMPA is the place where all information is reported once and made available to various competent authorities and other services provides. More than automate processes and its complexity, the most difficult part was to change the processes of people. In the first implemented phased, all government formalities are declared in VUMPA, and the declared information is shared among all government authorities. Highlights of the implementation (1) solve issues on regulatory procedures, legal matters, implementation methodologies; (2) redefine collaboration processes among the stakeholders of maritime transport; (3) Change Management, among others. Benefits include significant savings in cost and time for users.
