Description

The PDF Xpansion SDK 17 offers features, methods, and functionality that allow software developers to create PDF/A-enabled applications and software solutions. It provides a variety of options for creating, editing, and printing PDF, PDF/A, and XPS documents. These can be used to display and print them on paper and for conversions between these formats and exporting or importing from/to any other file format. PDF Xpansion SDK 17 also includes eInvoicing functionality for formats ZUGFeRD Factur-X, XRechnung, and Factur-X. It allows software developers to integrate EU-compliant electronic billing functionality (creation and display of electronic invoices, as well as the reading and printing thereof) according to EU standard. The SDK allows you to integrate these functions into Windows desktop apps for the PC as well as Windows Apps. It allows for modularized purchases of different functionality. This makes it very flexible and only the features that are actually required can be purchased.

Description

Rechnungswandler.de serves as an online e-invoicing solution tailored for freelancers and small enterprises in Germany. This platform facilitates the transformation of invoice data input through a form or extracted from various file types, such as PDF, Word, Excel, and scanned documents, into compliant XRechnung or ZUGFeRD formats based on EN 16931 standards. Users have the ability to review the extracted data and download the finalized invoice, while a viewer tool allows for the examination of incoming e-invoices. Since both the conversion and viewing processes occur locally within the browser, users' invoice files remain secure and are not uploaded during these tasks. The platform offers premium features that include the preservation of the original document layout, the capability for batch conversions, storing customer information, utilizing reusable templates, sending payment reminders, and generating validation reports. Additionally, an optional AI feature can assist by recommending any missing information. Users have the flexibility to create new invoices via the web form or modify existing documents, all without the need for desktop software installation. A free tier with certain usage restrictions is available, alongside paid plans that can be purchased for 24-hour access, monthly subscriptions, or annual memberships. Overall, Rechnungswandler.de combines convenience, security, and advanced features to streamline the invoicing process for its users.
