BT-25 — Preceding Invoice reference

field1 rules

Every EN 16931, Peppol and XRechnung rule that constrains BT-25. If one of them fails, the others are usually worth a look — a wrong value in one field tends to break several checks at once.

BR-55

fatal

Each Preceding Invoice reference (BG-3) shall contain a Preceding Invoice reference (BT-25).

All rules

Check an invoice against every BT-25 rule

…or paste the XML instead

Nothing is stored, and the whole invoice is checked, not just this rule. A PDF only works if it is Factur-X / ZUGFeRD — a PDF with the invoice XML inside it.
