Abstract: The present invention provides a software based system for end-to-end handling of communication services that includes a set of Web based interfaces. The set of Web interfaces can permit a user to view, search and select a set of communication services of different providers, each service being presented with a real-time price for the service. Contracts can be automatically generated for selected ones of the communication services. The contracts can specify the real-time price for each service. An order status of the communication services can be monitored using the set of Web based interfaces. Invoices can be generated for the communication services. When different providers provide the communication services, a single integrated bill can be provided for services of the different providers. Usages of the communication services can be viewed online by selectable user categories, which decompose into per-user usage entries.
