This is the solution where you decide what you need. Maybe you require several webshops with different designs, currencies or functionality - or you have a chain where each location is a separate store, but you would like a way to manage them from a central admin interface. Do you use an ERP system that we currently don't support? If we get proper documentation and a test environment we can probably make the integration. The list is long. Tell us about your requirements, and we will let you know what we can do.
