BT-10

Buyer reference

Raw

Reference provided by the buyer so they can route the invoice internally. In Germany it is the central routing field for public-sector invoices.

Practical note

For invoices to German public bodies this field carries the Leitweg-ID (pattern: 04011000-12345-03); XRechnung makes BT-10 mandatory in general. For B2B any buyer reference is fine.
