B2B Edition allows you to have multiple companies with the same name. The "Customer Group ID" will be the unique identifier for each company.

As a reminder, each time a new company is created, a customer group is automatically created in BigCommerce. BigCommerce however does not allow for customer groups with the same name.

So what will happen if you add a new company in B2B Edition with a duplicate name, the system will automatically add some random characters to the end of the customer group name in BigCommerce to make this possible.
