Rechnungsabweichungen und fehlende Leistungsabgrenzung bei Wartungsverträgen

1 verified sources

Definition

HVAC technicians bill by work units (1 AE = 15 minutes). Without integrated time-tracking, 3-8% of billable hours are either not invoiced or incorrectly billed. German service companies face revenue leakage from travel-time disputes, overlap between deployment fees and work units, and unclear transition costs (10+ km threshold per HGZ Berlin pricing model).

Key Findings

  • Financial Impact: €8,000–€25,000 per technician annually (estimated 3–8% unbilled hours at €150–200/hour rate)
  • Frequency: Continuous (every invoice cycle)
  • Root Cause: Manual work-unit tracking without real-time integration; no automated reconciliation between dispatch logs and invoices; ambiguity in billing thresholds (deployment fee overlap, travel-time assignment).

Why This Matters

This pain point represents a significant opportunity for B2B solutions targeting HVAC and Refrigeration Equipment Manufacturing.
