Bochum, Germany., June 14, 2022 – soft Xpansion has released PDF Xpansion SDK 16. The latest version of its developer libraries for implementing classic PDF and PDF/A features (create, edit, display, convert between formats, export, import) as well as modern eInvoicing functionality (create, read, validate,
visualize) in software applications.

The release comes shortly after this year’s FACTUR-X/ZUGFeRD Developer Days which took place on May 19 & 20. soft Xpansion also participated in this event. Two days were packed with technical lectures and exchange of views on eInvoicing, including information on the newest specification formats FACTUR-X/ZUGFeRD 2.2 and XRechnung 2.2. The practical relevance of the event was underlined by case studies on the use of ZUGFeRDor XRechnung in public administration (project of the city of Reutlingen) and in companies (Adolf Wuerth GmbH & Co. KG).

The PDF Xpansion SDK 16 supports the two newest FACTUR-X/ZUGFeRD and XRechnung eInvoicing formats as well as all older specifications. In addition, the export of XRechnung in UN/CEFACT syntax as UBL syntax is now also possible. And there are more innovations, independent of the electronic invoices subject: PDFs can now be signed digitally with solutions offered by third-party providers or with own crypto providers. Last but not least, optimizations for the PDF viewer and for the PDF/A conversion features have been implemented.
