To change your customer information, we require a written request form. You can find the form in our download centre: For address changes, you can find the form for doing so here. For changes to bank details, you can find the form for doing so here.

We would be happy to change your receipt text or your clearing name (the display of your name on the account statement of the cardholder).

To do so, we need you to send an email to serviceDE@nets.eu with your business partner number and the new receipt text/clearing name.

We would be happy to help with the change. You can reach us on the Freephone number +49 69 7922 4060 or via email at serviceDE@nets.eu and please remember to indicate your customer number.

We would be happy to send your mail to an alternative address. To do so, we need you to send an email to serviceDE@nets.eu with the following information:

• your business partner number (you can find this at the top of your credit card statements or terminal invoices),
• • the new address for sending invoices,
• indication of whether credit card statements and/or terminal invoices should be sent to this address.

Unfortunately, we are unable to send mail to a PO box.

Send us your new bank account details, ideally using our form (link to the form for change of bank details). If you do not use the form, please note the following:

• original signature (fax or letter), gladly scanned and attached to an email to serviceDE@nets.eu,
• SEPA direct debit mandate authorisation – purpose-of-payment text (for example: all payments and direct debits, payments for credit card transactions, terminal direct debits),
• for the respective account, conclude an agreement regarding debit card direct debits (officially ‘collecting receivables via direct debit from POS authorisations using service data centres’).

IMPORTANT: Please do not yet submit any sales via the card terminal!

The device has not yet been converted to your information and there is a risk that your sales will not reach you.

Please contact +49 69 7922 4060 or send an email to serviceDE@nets.eu. We will be happy to help with the remaining necessary steps.

Please note: Do not allow the new owner to use the card terminal. The device still has your information. If you do not intend to continue your contracts with us, then please inform us of this in writing. Please note that we require the information for your credit card contract and for your terminal contract. You are welcome to inform us of the successor to your business via email to serviceDE@nets.eu.

Simply call +49 69 7922 4060 or send an email to serviceDE@nets.eu, We will be happy to help you with the next necessary steps.

In the Concardis portal, you have access to your information at any time of day. In the portal, overviews of your conducted transactions as well as your statements for credit cards and invoices from your terminal are available to you for download and print. We do not send invoices separately via email.

If you are unhappy with your terminal or you need a different model (wireless, Wi-Fi function), we would be happy to advise you.

To this end, please contact our Freephone service number on +49 69 7922 4060.
