Abstract: The computer-implemented international trade system is the business logic of an expert system which manages, guides and integrates the complete export/import trade process of single cross-border merchandise trade transactions on behalf of a buyer and seller, each accessing the system remotely using personal computers and web browsers. This system is designed to be accessed by users in an application service provider environment, and utilizes a combination of currently existing e-commerce technology, computer server technology, extensible markup language, encryption software, and database software, all integrated and controlled by a unique series of software applications created around the business logic. The object of the invention is to minimize time, costs, risks and required process knowledge, while maximizing the probability of a successful outcome, for cross-border merchandise trade transactions, especially for small to mid-sized firms worldwide.
