A flowchart-based tool can be used to build a logical structure. In the context of a customer relationship management (CRM) system, the logical structure can comprise an ordered set of questions and branching logic that are presented to a customer of the business when the customer contacts the business with an inquiry, such as for a sale or service inquiry or other interaction. An engine can run a session associated with the logical structure, with the session presenting questions, text, graphics, and the like dynamically to customer across a network, such as the Internet and a web site. Branching logic determines the appropriate information to present to the user based on answers to previous questions. The engine allows presentation of the information to the user/customer, by generating hypertext markup language (HTML) files to display the questions or other elements of the logical structure as part of a user interface on a client terminal of the customer.
