IBIS subscriptions renew monthly on a continuous basis until terminated either by client election or for non-payment.  Clients may cancel the service by logging into Account Management and selecting the 'Cancel' menu option. As long as service is canceled prior to the billing date, no service fees will be incurred for the following month.  If service is canceled on or after the billing date, no refund or proration of fees is provided.  Regardless of whether cancellation takes place before or after the billing date, access to billed services will continue until the end of the month for which they have been paid.

Service will also be terminated if the billing charge is not honored by the credit card issuer due to invalid instructions, insufficient credit limit or an expired card. In each of these situations, IB will attempt to send an email notification of the matter prior to the initiation of the upcoming service period in an attempt to ensure continuity of service.
