What is BR-NL-01?
BR-NL-01 is a warning validation rule defined in the peppol-bis-3 specification (NLD national rules). It validates the CompanyID element under Party > PartyLegalEntity in the UBL invoice XML.
This is a soft validation failure. The invoice may pass initial transmission, but non-compliant values in this field can cause problems during tax audits, buyer-side processing, or downstream VAT reconciliation.

Why This Error Matters
KVK numbers help with business verification and are commonly expected on Dutch B2B invoices.
BR-NL-01 is a soft failure. The invoice may pass initial validation, but the non-compliant field can cause issues at the receiving end — tax authorities may flag it during audits, buyer ERP systems may fail to process it, or VAT reconciliation may produce mismatches. Fixing warnings before they accumulate prevents larger compliance gaps.
