We always send our invoices as PDF-files via e-mail. If you have placed an order with us, please also check your SPAM folder for your invoice. Should you like to receive your invoice by regular mail, please contact our customer service team.
Invoices for subscriptions are usually sent out approximately two to four weeks after ordering the subscription. Please remit your payment within 14 days. Should you have selected advance payment when ordering, your invoice will include the remark “Amount received”.
For single issue orders, you’ll receive the invoice along with the order confirmation, right after the ordering process has been completed. In this case, the invoice also carries the “Amount received” remark.
