Mobile Application brings together information from different sources to a single point of access. This is very vital information for shipping agents who operate in an industry where time of arrival, departure, approval, holds and even rejections from different entities will affect their next port schedule and could have a negative financial impact on the ports operator as well as the shipping agents.

This Mobile Application addresses the need for transparency in operations in an unprecedented way, pulling information from Port’s Authority systems, Marine Service provider systems, Customer Authority system, Port Operator system and the internet while providing a digital lighthouse in the palm of the shipping agent. This way, our customers are instantly informed about the actions happening in the real world.
