What are Organizations?
Organizations are the umbrella to a specific set of divisions. They can be determined however your team sees fit and can span multiple physical addresses if need be.
Busch Systems Headquarters could be an Organization with an Office and Warehouse as separate divisions within that Organization.
Busch Systems could be an Account with Busch Systems Canadian Headquarters as an Organization with multiple Divisions within it. Within the Account could also be Busch Systems US Headquarters within multiple Divisions within that Organization as well.
