We are always willing to help you, but you need to help us too.
I know it is difficult to get your company to pay all the outstanding, but I hope you could get your account to settle the outstanding for 2013 plus the invoice for this shipment.
Total: Euro5,403.26 + 774.60= Eur 6177.86
I will arrange your shipment once I received your payment.
I hope you understand my position here, as we need to report to my Germany office.
