Method and apparatus for a system for sharing a business process in the form of a software application (computer program) between at least two organizations. The shared software application is typically in the form of one or more web pages having associated data and logic and accessed by a conventional web browser and transmitted over the Internet between the two organizations. The two organizations need not have a shared computer system or even a common computer operating system. The business process underlying the software application may be for instance a vendor/supplier relationship but can be other more complex relationships such as third party sales representatives, business consulting, or computer support. The system includes the ability to configure the business process in terms of the software application which would include business logic and draw on data in the form of a database maintained by one of the organizations. The system uses a host server which supports both the software application and the sharing process.
