In the online shop and for initial orders (new customers), payment in advance applies. Invoices, including partial invoices issued directly by our company, are due for payment within 7 days of the date of issue, net, free of charges and deductions, in particular without discount deduction. Bills of exchange or cheques shall only be accepted by separate agreement and only on account of payment. We reserve the right to allocate incoming payments to any multiple claims at our discretion. If the customer is in default of payment, we shall be released from all further performance and delivery obligations and shall be entitled to withhold outstanding deliveries or services or to demand advance payments or securities. Furthermore, regardless of fault, the customer is obliged to pay default interest of 5% per month, whereby we are entitled to claim bank interest in excess of this at the usual rate. In addition, the customer shall reimburse us for the reminder costs and fees of the collection agency incurred by us, which result from the regulation of the BMWA on the maximum rates of remuneration due to collection agencies. If we issue a reminder, we shall be entitled to charge reminder fees. If a significant deterioration in the financial circumstances of the customer occurs after conclusion of the contract or if circumstances become known which, in our view, are likely to reduce the creditworthiness of the customer, all claims shall become due for payment immediately. In this case, further deliveries shall only be made against advance payment. Withholding or offsetting by the customer due to counterclaims of any kind whatsoever is excluded. In the case of export transactions, the customer alone shall be obliged to ensure that the necessary export, customs and other authorisations and the like are obtained and maintained at his own expense. We give no warranty or guarantee whatsoever for the permissibility of the export of the purchased goods. Furthermore, the customer must return all export and customs documents and the like to us in the original, otherwise he is obliged to pay any value added tax. In addition, in the case of deliveries abroad, the opening of an irrevocable documentary letter of credit with a bank to be determined by us, usable against presentation of the shipping documents or forwarding acceptance certificate, is a prerequisite for our delivery.
