BT-10 — Buyer reference

field2 rules

Every EN 16931, Peppol and XRechnung rule that constrains BT-10. 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-DE-15	fatal	Das Element "Buyer reference" (BT-10) muss übermittelt werden.
DE-R-015	fatal	The element "Buyer reference" (BT-10) shall be provided.

All rules

Check an invoice against every BT-10 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.
