Find the right solution for your organisation

  • For companies

    Initial Situation 1 Solution 1: [web form, upload, monitoring]

    Your company has no ERP system and only wants to send a small number of invoices per month.


    Use our web portal to generate electronic invoices in various formats: XRechnung, PEPPOL BIS.
    Other functions: copying or adapting old invoices, uploading invoices in XRechnung or PEPPOL BIS format, monitoring.

    You can enter the following invoice types in the portal:

    • Commercial invoice
    • Corrected invoice
    • Self-billed invoice
    • Credit note
    • Partial construction invoice

    Initial Situation 2 Solution 2: [web form, upload, monitoring] + [email/SFTP/API]

    Your company sends many invoices per month and can directly create the requested XRechnung or PEPPOL BIS format in its own ERP system.


    An e-mail, SFTP or API interface can be created between your ERP and our PEPPOL Access Point.


    Initial Situation 3 Solution 3: [web form,  upload, monitoring] + [email/SFTP/API] + [mapping]
    Your company has an ERP system but cannot send invoices in XRechnung or PEPPOL BIS format.

    Your finance department or ERP system can send us invoices in internal format (TXT, CSV, PDF, XML) via upload, e-mail, SFTP or API interface. 

    A mapping tool converts the invoices into XRechnung or PEPPOL BIS and sends them via e-mail or PEPPOL.

    TXT, PDF or XML mapping can be developed according to customer requirements.

    CSV interface is standardized.

  • For service providers

    Initial Situation Solution

    As a service provider you send invoices on behalf of your customers.

    You can create invoices via the web portal or transfer them automatically via an e-mail, SFTP or API interface. In addition, different authorisation concepts can be provided.  

    Additional functions: Group solution


  • For public authorities

    Initial Situation Solution
    You are an authority or public institution and have to be able to receive electronic invoices.

    You will be added to the PEPPOL register through us and therefore comply with the applicable EU directive. An access to the Invoice Portal will be created for you, where you can process your invoices.

    We can convert the invoices from Xrechnung or Peppol BIS format into your private format (e.g. IDOC). 

    Communication can be created via email, sftp or API.
