BR-08 — Missing Seller postal address
What it means
The Seller postal address is missing. EN 16931 requires the invoice to state the seller's address — a legal and practical requirement, not just a formality.
How to fix it
Check that the AccountingSupplierParty section of the invoice XML has a
PostalAddress block filled in (at least a city and country code). This
block is often missing when the company profile in the accounting
software isn't fully filled in.
Example
Wrong: the seller section has no PostalAddress block.
Correct: <cac:PostalAddress><cbc:CityName>Rīga</cbc:CityName><cac:Country><cbc:IdentificationCode>LV</cbc:IdentificationCode></cac:Country></cac:PostalAddress>.
