Axure is used for prototyping the UI and you can download the latest prototype for accelerators.
At Litium we believe in packaging. Meaning as much prepared material possible to the setting up of an e-commerce project. As a solution architect or designer, it is usually very helpful to do wire frames or prototypes. This helps in the process of setting the functional scope and design of a project, and it is usually a powerful in communicating this to a customer.
