Why run this now?

The law is coming

From 2026 B2B invoices in the EU must be machine-readable (ZUGFeRD / Factur-X / UBL). A plain PDF will no longer be enough.

Your supplier matters

Many accounting and ERP systems still emit invoices that do not comply. This check tells you immediately and gives you proof to send to your supplier.

No account, no risk

We only store your file encrypted for as long as the retention window. You can delete the report at any time via the share link.
