SoftSlate Commerce is a powerful and highly flexible shopping cart program written purely in Java and JSP. A Free Edition is available for stores selling 100 products or less. The Standard Edition has no restrictions of any kind and also includes the complete source code for the application. We have been continuously improving SoftSlate Commerce based on feedback from our clients since 2004 and it is now installed on hundreds of sites. SoftSlate integrates with several major payment gateways including PayPal and Authorize.net, as well as UPS and USPS. The interface is entirely CSS-based for easy customizations of the look-and-feel. A great many other features exist. SoftSlate was designed from the ground up to be extended and customized. In many senses it is not only an application but also a framework, for building a unique solution to any ecommerce project you have. If you need help implementing a solution, SoftSlate provides custom development and support services.
