Official rule sets up to date: EN 16931 1.3.17 · Peppol BIS 3.0.20 · XRechnung 3.0.2 (KoSIT 2.6.0). Last checked against the sources on 12.10.2026.
What the viewer shows
The upload runs the same check as the validator. When the invoice can be read, you see the seller, buyer, line items, VAT and totals, and payment details when the file has them. The preview stays on the page when the rules find errors.
The findings under the preview are the full validation: every error with its rule code and where it is in the file.
Which files you can open
XRechnung in UBL or CII, a ZUGFeRD or Factur-X PDF with the invoice embedded, Peppol BIS Billing 3.0, and other UBL 2.1 invoices. The format is detected from the file. The limit is 10 MB.
KoSIT validator — XRechnung is checked against the same KoSIT rules.
