* The monthly fee and variable service fee will be applied from the moment a paid level subscription is contracted beyond the free of charge available basic option. In all cases, upon subscription, credit card details will be asked for formalizing payment of the fixed monthly fee and the variable service fee, however those will only be charged to the corresponding users of Circular in Motion® with paid level subscriptions. The subscription fee charges will always be applied to the credit card used upon subscription. In the case the credit card limit is exceeded (meaning, if Circular in Motion® got a failed payment) we will warn the client. The client has the option to opt-in for generating an invoice for direct billing or to raise their credit card limit. If the client opts-in to receive an invoice for direct billing instead, a surcharge of 2,9% of the invoice value will be applied. The minimum invoice value amount will be of two (2) Euros per invoice.
