PDF Xpansion SDK
The PDF Xpansion SDK provides features, methods and functionality that let software developers create PDF and PDF/A enabled applications and software solutions. It offers a wide range of options for creating and editing PDF, PDF/A and XPS documents, for displaying and printing them on paper, for conversions between these formats, exporting and/or importing from/to other file formats.
Moreover, PDF Xpansion SDK comes with eInvoicing functionality for the formats Peppol BIS Billling, Factur-X, XRechnung. It enables software developers to integrate EU-compliant electronic invoicing functionality (create, display, convert, and read electronic invoices) according to EU standard 16931 in applications.
The SDK is made to integrate those functions into both Windows desktop applications for the PC and for Windows Apps. The pricing model is flexible, since it allows a modularized purchase of separate functionality, so only those features have to be paid for that are really needed.

Facturwise
Facturwise is an invoicing platform for EU freelancers and small businesses with ZUGFeRD and Factur-X e-invoicing compliance built into every plan — including free.
Germany mandates e-invoicing from 2027, France from September 2026. Most tools charge extra for compliance or don't support both standards. Facturwise generates fully compliant ZUGFeRD 2.4 and Factur-X 1.0.8 invoices automatically — no plugins, no configuration, no extra cost.
Every invoice is a hybrid PDF/A-3 document with structured CII XML embedded inside — human-readable for your client, machine-readable for their accounting software.
Beyond compliance: multilingual invoices in 6 languages, 30 currencies, SEPA QR codes for zero-fee bank transfers, automated recurring billing, payment reminders, expense tracking, client management, quotes, credit notes, and a financial dashboard.
Start free, no credit card required.
