I suppose GDC will implement two buttons to your customer order management page you received the URL in your invoice Please forward my refund to Neo900 UG Please send my refund to this account: "BIC:____; IBAN:_____; Bank Name:____" Then you'll receive a mail from GDC asking you to visit your customer order management page and select either of both. I don't know exactly what Nikolaus is planning to do, but this approach seems least effort for customers and him. cheers jOERG
