Elektronische Rechnungsstellung (E-Invoicing) Compliance-Risiko und Bußgelder
Hard: €5,000–€1,000,000 per audit finding (Bußgeldkatalog). Soft: €50,000–€500,000 annually in manual rework, vendor dispute resolution, and audit defense costs. Logic: 15–40 hours/month manual invoice correction @ €150/hr = €2,700–€7,200/month (€32,400–€86,400/year).E-invoicing mandate (Wachstumschancengesetz 2024, phase-in through 2028) requires all B2B invoices to be machine-readable XML (XRechnung). Marketplace commission invoices—issued as credits, vendor payout deductions, or reversal adjustments—must comply. Manual commission reconciliation systems often generate PDFs or unstructured spreadsheets, failing audit trails. Betriebsprüfung (tax audits) flag non-compliant reconciliation records as evidence of bookkeeping violations (Buchführungsmängel) under GoBD. Platform operators face: (1) Bußgelder (€5,000–€1,000,000), (2) vendor vendor refund demands if commissions cannot be substantiated, (3) loss of vendor tax deductions (vendor liability shift to platform).
Kundenrücksendungen und Refundierungskosten durch Oversell-Stornierungen
€3,000–€12,000 annually per 1,000 orders. Calculation: 40 orders cancelled/year (4%) × €75 avg order value × 15% net loss (refunds + returns + reputational impact) = €4,500.When overselling occurs and orders are cancelled post-payment, multiple costs accumulate: (1) Refund processing (2–4 days; merchant absorbs payment processor fee: €0.30–€0.60 per refund). (2) Return shipping label issuance (€2–€5 per return). (3) Reverse logistics and restocking labor (€1–€3 per unit). (4) Marketplace penalty: High cancellation rates (>2%) trigger algorithm demotion, reducing visibility by 20–40%, translating to 5–10% sales impact. (5) Customer churn: Cancelled orders correlate with negative reviews; 1 star reviews reduce conversion by 10–15% on peers. (6) Chargeback risk: Customers dispute cancellations, triggering additional fees (€15–€25 per chargeback) and account suspension if >1% rate.
