Changes to the invoicing process!

DekaBank Deutsche Girozentrale has switched to electronic invoices!
From now on all invoices will go through our partner OpusCapita Software GmbH.

Please note that the process described does not concern invoices for special assets of the financial investment management company Deka Immobilien Investment GmbH / WestInvest Gesellschaft für Investmentfonds mbH, represented by Deka Immobilien GmbH. Likewise this process does not concern invoices that have DekaBank Deutsche Girozentrale Luxembourg S.A. as the invoice recipient.
The benefits for you as a supplier are as follows:

  • time and cost savings when generating digital invoices
  • transparency during invoicing
  • quicker processing and delivery of invoices
  • legal and VAT compliance when delivering electronic invoices

For the invoice delivery process, our partner OpusCapita will make the following delivery options available to you through its Business Network:

  • Electronic invoicing (eInvoice)
  • E-mail invoicing in PDF format
  • Invoice submission using the “OpusCapita Business Network”

To do this, you must register your company once using the OpusCapita Business Network’s Onboarding Service. Simply follow the link below to start the onboarding process via “Registration”.
If you have any questions, please contact our partner OpusCapita Software GmbH on +49 (0) 231-3967-350.
There are no connection or transaction costs charged for invoice delivery.
Please note that for us to process your invoice efficiently, you must include our order number or a Deka contact with their e-mail address in your invoices. Only then can we guarantee that we will process your invoice promptly and accurately. Invoices without an order number or the name of a Deka contact will be rejected in the future.
We would also like to point out that your invoice(s) should be sent only once and using only one delivery method. Duplicate invoices cause unnecessary payment and processing delays!
If you want to send invoices via e-mail in PDF format, please now use the relevant company’s official e-mail address:
