Treesoft Zugferd Creator
If you want to create a ZUGFeRD invoice from an XRechnung and the corresponding PDF invoice, then this tool is just what you need.
You can download the free open source tool, which we have already compiled for you, here. It is a command line tool.

However, we recommend using Treesoft ZUGFeRD Creator. This tool has a graphical user interface that makes it much easier to use. In both cases, you will need an XRechnung invoice and a corresponding PDF invoice in /A-3 format.

Price
Depending on the version you choose—FREE, BASIC, PLUS, or PRO—in combination with the token package you select, creation costs between EUR 0.20 and EUR 2.00—the choice is yours.
Order tokens in the online shop
Downloading the e-invoice toolkit and setting up a token account does not entail any obligation on your part.
Convert PDF to XRechnung
If you want to convert your PDF invoice into an e-invoice (i.e., XRechnung), then Treesoft PDF2XRechnung Converter is just what you need. Of course, the converter also generates a ZUGFeRD invoice at the same time.
