Zahlungsverzug durch Retentionen nach VOB/B § 16

2 verified sources

Definition

Payment retention (Retentionen) is mandatory under German construction law. Principals withhold 5-10% of progress invoices; this amount is often held until final completion or converted to warranty guarantees (Gewährleistungssicherheit). Manual processes cause delays in (1) invoice submission, (2) defect verification, (3) retention release paperwork, and (4) final account settlement.

Key Findings

  • Financial Impact: €50,000-€150,000 annually (per €1M annual contract value), measured as opportunity cost of withheld cash at typical 5% annual borrowing cost. For a contractor with €5M revenue and 60-day average retention: €41,666 in annual working capital drag.
  • Frequency: On every invoice (monthly or per milestone). For a contractor with 50 active projects: ~50-100 payment cycles/month affected.
  • Root Cause: Manual payment processing, lack of automated dispute resolution, slow retention-to-guarantee conversion, paper-based final account documentation.
