A method is presented for providing a Customer hosted chat invitation to a browsing user. A service provider provides a Customer with a set of interactive invitation input objects, and the Customer creates and stores a set of customized invitation setup data from interacting with the input objects. The service provider runs custom code to generate, from the set of customized invitation setup data, an invitation program code module characterized by a set of programmatic invitation criteria. The invitation program code module is connected to a web page creating program code that resides on a web server operatively associated with the Customer site so that the browsing user's choices can be monitored and stored and, when selected invitation criteria are met by these choices, an invitation event is triggered. System claims to related subject matter are also presented.
