Express will rate its own premium rate before calling the Enterprise Application those data will be processed and converted into express equivalent data. In order to have the Farmers premium for the existing 21st century rated premium it will call the web service which is available in the Enterprise Quote System to get the Farmers premium rate by sending the rated premium data back in the form of XML file which has been processed through Online Quote for Century Client. Web service is used to call the express EAI service to have Express premium for AUTO, HOME, and LIFE.

Express Application will provide a single platform for all Agents to make new polices in single platform. Currently eAgent allows agents to make a policy undergoing 6 different pages and validations which puts extra load on mainframe server's, increases cost and validation from servers. Express will provide agents with an option where they do not have to navigate to different pages and would be able to rate and issue a policy in a single page with web 2.0 advanced page design. This will fastened process and reduce the time constraints agent use to create a single policy traveling different pages and hitting mainframes each time they navigate the page. It will also increase the MIPS rate hence increasing the performance and reducing the cost.
