Future statements or account balances will exclude voluntary amounts unless specifically included at the time statements are created/balances are viewed. If you are on an accrual basis and need to recognize voluntary fees only when they are paid (i.e. prevent them from reporting as an outstanding Accounts Receivable balance in your accounting software) you can contact Support to have this feature enabled.

2. Select the Statements tab within the Billing module.
