Unzureichende Change-Order-Verwaltung verursacht Margen-Erosion bei Fortschrittsbillierung
Definition
Change orders occur daily in custom projects: Customer adds feature (+€10k), supplier raises material cost (+€5k), technical redesign required (+€20k). Manual process: email approval from customer → handwritten change order → sales engineer calculates impact → finance notified 1–2 weeks later → invoice adjustment applied to next cycle or forgotten. Multi-month projects = 10–30 change orders = high risk of missed cost recovery. Machinery manufacturers absorb cost overruns to 'maintain customer relationship' (implicit write-off).
Key Findings
- Financial Impact: €50,000–€300,000 annual margin loss per machinery manufacturer (10–30 change orders/year × €2k–€10k average unbilled cost per order). Example: 20 change orders/year, 40% not billed = 8 unbilled × €5k = €40k loss. Typical machinery builder margins: 15–25%; unbilled overruns = 1–2% margin erosion per year.
- Frequency: Continuous (1–5 change orders per project; 5–10 projects simultaneous)
- Root Cause: Manual email-driven change order approval; no structured workflow; cost capturing (procurement invoice linking to change order) not automated; 4–6 week lag from approval to invoice adjustment; change orders 'forgotten' if not explicitly escalated.
Why This Matters
This pain point represents a significant opportunity for B2B solutions targeting Agriculture, Construction, Mining Machinery Manufacturing.
Affected Stakeholders
Project Manager (change order initiation & tracking), Sales Engineer (cost calculation), Procurement (supplier cost capture), Finance/Controller (margin tracking, final account)
