PDF Xpansion SDK E-Invoicing by soft Xpansion is a comprehensive software development kit for creating, processing, and managing electronic invoices in compliance with international standards. It simplifies integration into existing applications and supports structured invoice data in XML as well as hybrid PDF/A formats, including common standards such as ZUGFeRD, Factur-X, and XRechnung. The SDK enables developers to create, edit, display, and extract data from compliant invoices, supporting automated digital invoicing workflows, legal conformity, and straightforward connection with accounting or enterprise resource planning (ERP) systems.
The PDF Xpansion SDK v17.2.7 update adds support for ZUGFeRD 2.4, allowing applications to generate and process e-invoicing documents that align with the latest version of the German and European e-invoicing standard based on EN 16931 (European Norm 16931). For software developers, this support ensures continued compatibility with evolving regulatory requirements, improves interoperability with trading partners and public sector systems, and reduces the risk of invoice rejection caused by outdated schemas or validation rules. By targeting ZUGFeRD 2.4, applications built on the SDK can handle current e-invoicing profiles with greater reliability while remaining suitable for long-term maintenance in compliance-focused environments.
