Use an existing invoice PDF
Keep the layout of a compatible invoice PDF. Enter the invoice data and compare it with the original by hand.

- Compare the document and data
- Save a separate enriched copy
Compatibility Embedding XML alone does not make an existing PDF PDF/A-3 or ZUGFeRD compliant. Signed, encrypted and unsupported PDFs are excluded.

Use the DocumentStudio template builder to give your ZUGFeRD PDFs your own look while keeping the invoice data intact.
Logo and brand color
Import your logo and choose a brand color, with the option to enter an exact hex value.

Three layouts to start from
Linear

Questions about the app
What does DocumentStudio do today?
It is a desktop app for preparing outgoing invoices and exporting XRechnung XML or generated ZUGFeRD PDFs. It includes local customer details, company settings, saved drafts, invoice styling and export history. Bookkeeping, payment reconciliation and incoming-invoice automation are outside the current scope.
Does it work without an internet connection?
Yes. Invoice authoring, the app's checks and file export run locally and work offline. Installation, updates and support are agreed as part of the pilot setup.
Is the app available in these four languages?
This website is available in German, English, Russian and Polish. The application interface is currently in German. DocumentStudio creates German XRechnung and ZUGFeRD formats; it is not presented as a connection to other countries' national invoicing platforms.
Can I use a PDF I already have?
Yes, if it is compatible. You enter the structured invoice details and manually compare them with the PDF before saving an enriched copy. The original stays unchanged. This is not automatic OCR or a general conversion of arbitrary PDFs into conforming ZUGFeRD files.
Which computers can I use?
Windows 11 x64 and macOS builds are being evaluated. The exact installation and supported workflow are checked in a guided pilot before routine use. There is no public self-service download on this page.
What can a pilot include?
One company profile, one reusable invoice style, representative test invoices and an agreed file destination. Your IT partner can help define installation, training and support. Price and license terms are agreed for the actual scope.
