All prices are net and payment must be made within 30 days of receipt of the invoice (electronic or paper), always prior to the date of shipment or collection. Special offers may have other conditions, which will be stated at time of offer. All invoices must be paid in full, including any bank commission fees that may be deducted. Late and overdue payments are subject to a 6% interest fee per year. The interest charges will start to accrue 30 days after the receipt date of invoice. Such interest is payable without the need for a further reminder. ARVI SA accepts payments by bank transfer or credit card (Visa, MasterCard) in Swiss Francs. In the event of partial or non-payment within a certain period of time, ARVI SA reserves the right to cancel the order and to charge the buyer a cancellation fee of 35% of the outstanding amount.
