Unbilanzierte Wartungskosten und verlorene Abrechnungen

3 verified sources

Definition

In residential portfolios, maintenance costs are typically passed to tenants via monthly surcharges or annual accounting settlements. Manual intake and dispatch create billing gaps: (1) Contractor invoice arrives → no automated receipt/acknowledgment, (2) Invoice filed manually → risk of misplacement or duplicate payment, (3) Cost allocation to tenant account requires manual lookup → errors cause billing delays or tenant disputes, (4) Year-end accounting finds 5–10% of invoices not yet billed to tenants. For a 200-unit portfolio with €50,000 annual maintenance spend, a 2–3% leakage represents €1,000–€1,500 in unbilled costs annually.

Key Findings

  • Financial Impact: €5,000–€20,000 annually per portfolio: (1) Unbilled maintenance costs (2–5% of maintenance spend): €1,000–€5,000 annually for typical 200-unit property; (2) Duplicate invoice processing (1–2% error rate): €200–€500 annually; (3) Billing disputes and follow-up labor (10–15 hours/month @ €20/hour): €2,400–€3,600 annually; (4) Bad-debt provision for disputed/unrecovered costs (0.5–1%): €250–€500 annually. Larger portfolios (500+ units): €15,000–€40,000 annually.
  • Frequency: Continuous; affects 5–10% of all maintenance invoices processed.
  • Root Cause: No centralized invoice tracking system. Invoices managed via email, paper folders, or basic spreadsheets with no automated matching to tenant accounts or cost allocation workflows.
