Correct. You can have ABC and XYZ companies set up with their own templates, customers, items, etc. and the login info (which is a system-wide table) will determine which templates and data they use. Both share the same folders on the IIS server so you'll want to be sure each company uses customized templates with unique names unless you want them to look the same. Also, be sure the item image names are unique unless, again, they share items.
