Unbilanzierte Zusatzleistungen und Abrechnungsverluste bei fehlender Änderungsantrag-Dokumentation
Definition
Construction contracts in Germany are governed by VOB/B (Vergabe- und Vertragsordnung für Bauleistungen). Article 4 VOB/B requires formal change order documentation and approval before contractors can claim payment for work outside the original contract scope. Without standardized, tracked change order processes, services are performed but either never invoiced or disputed during payment verification. Manual processes create gaps where verbal agreements are not captured in writing, leading to 'handshake' contracts with no audit trail.
Key Findings
- Financial Impact: €2,000–€8,000 per construction project in unbilled services; typically 1–3% of contract value lost to documentation gaps and payment disputes
- Frequency: Per change order cycle; 5–15 change orders per medium-sized project typical
- Root Cause: Manual change order initiation, lack of standardized templates, no centralized approval workflow, poor audit trail, contractor-subcontractor miscommunication on scope boundaries
