Billing-Fehler in Settlement-Berechnungen führen zu Refund-Cascades

2 verified sources

Definition

Manual PPA billing introduces calculation errors in 1–3% of invoices (industry standard). Given average PPA invoice values of €5,000–€50,000, errors trigger refunds of €50–€1,500 per incident. With 50+ invoices/month, this represents €2,500–€45,000 annual refund exposure. High-value customer dissatisfaction can lead to PPA non-renewal, eliminating 3–20 years of contracted revenue.

Key Findings

  • Financial Impact: €50,000–€500,000 annually (refunds + foregone contract renewals); 10–30 hours dispute resolution per billing cycle
  • Frequency: 1–3% of invoices; ongoing throughout contract term
  • Root Cause: Manual formula implementation in spreadsheets; inconsistent data source selection (spot vs. intra-day vs. settlement prices); staff turnover and lack of standardized billing procedures; inadequate testing of settlement logic before invoice issuance
