Ausgangs- und Eingangsbelege erhalten Skontosatz und Frist, mit Vorgaben bei Kunden und Lieferanten. Das PDF ergänzt automatisch einen Skontohinweis (oder nutzt neue Textvorlagen-Variablen); bei Schlussrechnungen gilt der Skonto für die Restforderung. Skontobedingungen werden aus E-Rechnungen (#SKONTO# und ZUGFeRD) sowie von der KI-Vorbereitung übernommen. Die Bankzuordnung erkennt Zahlungen abzüglich Skonto innerhalb der Frist und bietet sie in der Vorschlagsübersicht direkt an. BWA-Erlöse und -Aufwand berücksichtigen gebuchten Skonto im Zeitraum der Zahlung. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
