7. Invoicing and payment

a) Our invoices shall be paid in full within 10 days of issue. Even if payment is made early, the client shall not be entitled to deduct any discounts. Bills of exchange or cheques, which we are not obliged to accept, shall be provided exclusively on account of performance. Payment shall only be deemed to have been made upon their encashment or discharge.
b) For partial invoices the same terms of payment as specified for the overall contract shall apply. In any case, partial deliveries may be invoiced separately.
c) If payment is delayed, a default interest rate of 12% p.a. shall be applied. The costs incurred through the intervention of a lawyer in the case of default of payment – as far as appropriate and necessary - shall be borne by the client in accordance with the Austrian Act on the Tariff of Lawyers' Fees (RATG).  These costs shall be borne by the client in particular in the case of damages. Additionally, payment reminders may be charged at a rate of EUR 25 each.
d) We may rescind the contract or demand damages on the grounds of non-performance if a payment deadline of one week set by us as of the due date is not complied with. Any claims for damages (due to wasted expenses, lost profits, etc) shall not be compromised by our rescission. 
e) If financial circumstances deteriorate substantially after conclusion of the purchase contract or if we later learn that they are significantly worse than assumed, we shall be entitled to make delivery contingent on the client’s previous settlement of any and all payments due, including payments for other deliveries from us. If delivery has already been performed, we shall be entitled to reclaim the goods and to retain them until the client has fulfilled all payment obligations to us. Any debts collateralised by bills of exchange with a later maturity date shall also become due without delay. The provisions of this paragraph shall also apply if we have included bills of exchange and we receive unfavourable information about the acceptor’s or the drawer's financial situation 
f) The client can only set off his claims against claims that have been determined indisputably and legally effective, but in no way against counterclaims from other legal transactions. The client does not have any right of retention.
