EInvoice Private – XML Viewer

An XML viewer and e-invoice validator for European invoices: open ZUGFeRD, XRechnung, Peppol UBL or Factur-X files and see within seconds whether they are valid, what they say and what to fix. The XML viewer works offline and the files stay on your device: no account, no upload, no tracking.

PDF AND XML MATCH?
A ZUGFeRD or Factur-X invoice is a PDF for people plus an XML file for software. When they disagree, your books record one amount and the page shows another. EInvoice Private compares them field by field (number, dates, amount due, totals, IBAN, seller, buyer) and lists every value missing from the page.

THE OFFICIAL RULES, OFFLINE
The check runs the unchanged official rule files on your device: EN 16931 validation artefacts (CEN) and the XRechnung Schematron (KoSIT), plus the UBL 2.1 and CII D16B schemas. Every result shows which rule versions were used. In our test on 2184 official and test invoices, our valid/invalid verdict matched the official KoSIT validator in every case.

WHOLE FOLDERS AT ONCE
Pick a folder (sub-folders included) or several files and get a table: file, format, seller, number, amount due, valid or invalid, first error, PDF/XML differences. Export the table as CSV for Excel or Google Sheets.

ERRORS IN PLAIN WORDS
For the common rules (BR-DE, BR-CO, BR) the app says what is wrong and how to fix it, in 31 languages. The rule ID and official text stay visible for your software vendor.

CREATE E-INVOICES

FREE AND PRO
Free: open, read and check single invoices without limit, the PDF/XML comparison, batches or folders of up to 3 files, and 3 new invoices per calendar month (counted on this device).
Pro (auto-renewing monthly or yearly subscription, or a one-time lifetime purchase with no renewal): unlimited invoices, batch and folder checks of any size, saved customers and items, your logo on the ZUGFeRD PDF, and a history of opened and created invoices with "duplicate as new".

PRIVACY
Invoices are read, checked and created on your device. The app has no account, no analytics, no advertising and does not send invoices anywhere. Purchases are handled by Google Play.
