What's the difference between online and corporate accounts?

Some billing contacts log in to the Billing Center to manage their GoToTraining billing info themselves. However, other billing contacts for larger accounts (referred to as "corporate" accounts) typically work with a LogMeIn representative to manage their account on a different self-service site called the Corporate Billing Portal.

Billing Center 

The Billing Center allows billing contacts to add and manage subscription plans, change billing frequency, view and print the billing history for each renewal, and update payment information.

Corporate Billing Portal

The Corporate Billing Portal allows billing contacts for "corporate" GoToTraining accounts to change billing contacts, edit Purchase Orders, and manage price quotes with a LogMeIn representative.

Billing contacts for these accounts must contact a LogMeIn representative to add subscriptions for additional products or change the billing contact for the account.
