The Balances area shows what the customer owes and what credits the customers has. There are two main types of balances:
Currency balances, which are shown in green and have a currency symbol. The balance represents money owed for the services associated with the balance. If there is a credit limit for the amount owed, that is shown with the balance.
Noncurrency balances, which are shown in blue and do not have a currency symbol. Noncurrency balances represent tokens, minutes, loyalty points, and so on, that are associated with the service.
