BKK WIRTSCHAFT & FINANZEN is legally obligated to receive and process electronic invoices from suppliers and service providers via digital channels without media disruption.
The invoice receipt platform at https://portal.b4value.net/edi is available for the transmission of electronic invoices.
Invoice issuers have the option of creating invoices in a standardized format or uploading and sending an invoice that has already been created. The transfer of invoices via the PEPPOL network and by email is also supported.
Background:
Section 4 of the Federal E-RechV (E-Invoicing Ordinance) specifies the requirements for the invoice data model and transmission. The public administration accepts XRechnungen (XInvoices) and other electronic invoices that comply with the European standard EN 16931 and the E-RechV. In addition, e-invoices to BKK W&F must meet the terms of use of b4value.net GmbH.
Further information about the XRechnung standard is available at www.xoev.de/de/xrechnung.
Important:
- Electronic invoicing is mandatory for invoice issuers. Exceptions are regulated in § 3 paragraph 3 of the E-RechV. If you are not obliged to submit electronic invoices, please send your invoices by e-mail or post to BKK WIRTSCHAFT & FINANZEN (Bahnhofstraße 19, 34212 Melsungen).
- Even if you are not obliged to do so, invoice issuers can also use XRechnung. Processing is significantly shorter due to the technical runtimes and therefore also has significant advantages for invoice issuers.
We will be happy to answer any questions you may have about XRechnung on 0561 51009 800.
Note: The XRechnung requirements described do NOT apply to insured persons. If insured persons would like to send us something, please use the e-mail address info@bkk-wf.de .

Permitted file types for embedded documents are: “png”, “pdf”, “jpg”, “jpeg”, “xlsx”, “ods” and “csv”. Attachments may not contain any active content (e.g. macros). Changes to these restrictions will be announced via the invoice receipt platform.
- Invoice documents with attachments that require a paper-based mode of dispatch under other legal provisions (e.g. proof of export or customs documents) remain unaffected by the above provisions.
Invoice transmission
- Only the aforementioned invoice receipt platform is to be used for the transmission of electronic invoices. This requires prior registration and activation of the desired transmission channels.
- Electronic invoices sent by other means cannot be taken into account.
- It is not permitted to send invoices with the same invoice number both in electronic form and on paper. Please only use the electronic invoice format in future in order to reduce the number of possible duplicates.
