This app supports reading and writing electronic invoices according to the UN/CEFACT Cross-Industry-Invoice (CII) standard in the following profiles:

• BASIC

• EN 16931

• EXTENDED

• XRECHNUNG

All profiles except for "XRECHNUNG" can be embedded in a PDF file, known as ZUGFeRD or Factur-X.

This app cannot read or write UBL invoices. It also does not provide any special way of sending or receiving e-invoices (e.g. Peppol). Instead, it focuses on the conversion between ERPNext's internal data model and the XML format of the above standards.

To download the XML file (XRechnung), open a Sales Invoice and click on "..." > "Download eInvoice".

When you open the print preview of the Sales Invoice and click on "PDF", the generated PDF file will have the e-invoice XML embedded. An exception is the E Invoice Profile "XRECHNUNG", which is intended to be a plain XML file. In this case, the PDF will not have the XML embedded.

To import a new eInvoice, create a new E Invoice Import and upload the XML or PDF file. After submitting the E Invoice Import, you can create a mapped Purchase Invoice.
