Winning Cargo User & Data Management

I was approached by this international freight company and asked to add a function to their site that allows their customers to log-in and perform tasks such as browser shipments, and change their account profiles. They also wish to have a system that allows the staff to store new shipments into the database, modified existing shipments, and add new users to the system. Since each shipment involves an extensive amount of information, they also expect the system to have features like filtering, sorting, as well as allow them to download data to their local machine in the format of xlsx for recording purpose.
