BR-07 — Missing Buyer name
What it means
The Buyer name is missing. The invoice must state the name of the company or person receiving it — without it there's no unambiguous way to tell who the invoice is addressed to.
How to fix it
Check that the AccountingCustomerParty section of the invoice XML has the
name field filled in (RegistrationName or PartyName). If the invoice is
issued from accounting software (Jumis, Horizon, 1C, etc.), check whether
the buyer's record has its details fully filled in before the invoice is issued.
Example
Wrong: the buyer section has no name field at all.
Correct: <cac:PartyLegalEntity><cbc:RegistrationName>SIA Pircējs</cbc:RegistrationName></cac:PartyLegalEntity>.
