We are trying to figure out if there is a way to consolidate customer and vendor info in NS. For example, we have a customer that is a customer of several subsidiaries in NS and also a vendor of subsidiaries. Is there a way to register transactions through 1 company that captures both customer and vendor info?

Currently this is not possible since customer and vendor are two different entity types. NS now allows sharing vendors and customers in between subsidiary and cross sub employees are coming, but as far as I know combined customer and vendor entity is not in their roadmap

i assumed so, so only solution would be to create a diffrent version of those customers and vendors...i.e..Google 1....Google 2

I believe you can create a relationship between them to denote that they are actually the same company (with two different relationships (customer/vendor) to your company). Haven't played with this feature extensively though so can't provide much help beyond the basics. Check out SA Answer Id: 9648 "Records as Multiple Types"
