Company Type distinguishes between several important types of companies.
Some Customer Types are used as constants. It's safe to add new sub-types of Customer or Provider.
Constants:
The following company types are reserved and should not be edited:
CustOrIntl - Super-type for both Customers and Internal companies. Used for the Project's customer drop-down field in order to allow projects for internal companies, as well as for customers.
Customer - Companies buying from you. Used frequently across the system. Please use Customer as a super-type when adding a new type of customer
Provider - Companies from whom you are buying. Used frequently across the system. Super-type of all providers
Internal - Refers to your own company
In order to add an additional company type you should create a sub-category of one of these top categories.
