Credit Notes Support (v1.6.0)

Generate PEPPOL-compliant Credit Notes with automatic validation:

use Darvis\UblPeppol\UblBeBis3Service;

$service = new UblBeBis3Service();
$service->createCreditNoteDocument();  // Not createDocument()!
$service->addCreditNoteHeader('C2026-001', '2026-01-21');
$service->addBillingReference('F2026-050', '2026-01-15'); // REQUIRED (BR-55)
// ... add parties, lines, totals ...
$xml = $service->generateXml();

Key Points

• Use createCreditNoteDocument() instead of createDocument()
• addBillingReference() is REQUIRED (PEPPOL BR-55)
• All amounts must be POSITIVE (credit nature = document type 381)
• Use addCreditNoteLine() instead of addInvoiceLine()
