I am looking for commerical enterprise-level shopping cart solutions that can be intergrated with SharePoint 2010. The shopping cart would handle services for new and existing customers (think telecom, not products - i.e. phone packages, internet packages, etc.). I have seen a number of shopping cart solutions that work great for products, but not so much for services, packages of services, customizations on services, etc.
We would need a solution that allows us to manage the available services, the available packages of services, and the available customizations to those services and packages. In addition, we would need to be able to provide existing customers a way to start the shopping cart process with their existing products and customizing from there.
SharePoint is our platform for our public website. I'd like to find all of the options out there so that I can review the different commercially available shopping cart solutions that may work for us. These can include solutions that have direct integrations with SharePoint as well as ones we would need to do some custom development to make the integration with SharePoint. "Integration" is from the customer interaction point-of-view, not necessarily the backend management of the shopping cart.
The only caveat I throw out there is that the solution itself needs to be .NET-based. No Java or other platforms.
I look forward to hearing what is out there and your personal experiences with the solutions. Thanks.
