ForE-retailers and Marketplaces (>4,000 parcels/month), transport disputes represent 2-8% of total volume. Poorly managed, they reduce your NPS by 30 points. Properly outsourced, they improve it by +25 points, and turn each incident into a loyalty-building opportunity.
NPS goes beyond measuring customer satisfaction and determines how many customers are loyal to your brand. In e-commerce, delivery represents the last point of contact before final customer evaluation. NPS for both buyers and sellers reveals strong and weak signals about satisfaction, particularly when it comes to managing delivery incidents.
This strategic guide is aimed at E-commerce Directors, Customer Success Managers and Marketplace Managers who manage more than 4,000 shipments a month and are looking to transform their transport dispute management from a cost center into a lever for NPS improvement and competitive differentiation.
The Paradox of Transport Litigation: Between NPS Impact and Cost of Management
The Economic Reality of Internal Disputes
Internal management of transport disputes generates considerable hidden costs:
Actual cost per dispute (Internal Management)
- Agent time: 45-90 minutes per case (investigation, Carrier contact, follow-up)
- Blended hourly cost: €35-45 (salary + charges + overhead)
- Average total cost: €75-100 per dispute (data from Vinted and other European pure players)
Typical volume (4,000+ parcels/month)
- Average litigation rate: 2-8% depending on sector
- Monthly volume: 80-320 disputes to handle
- Annual Internal Budget: €72,000 - €384,000
This workload often represents the equivalent of 2-3 FTEs dedicated solely to managing delivery incidents.
Critical Impact on NPS: Potential for Improvement
An NPS above 0 is considered a fair satisfaction score, but e-commerce leaders aim for much higher scores. Apple sells its products at a higher price than its competitors, but enjoys 87% customer loyalty thanks to an exemplary customer experience, particularly in the event of a problem.
Litigation-NPS correlation: Potential for Improvement
- Résolution < 48h : Amélioration NPS +25 points vs gestion interne standard
- 3-7 day resolution: NPS improvement +5 points (vs -15 internally)
- Resolution > 7 days: NPS impact -25 points (vs. -45 internally)
- Proactive communication: Bonus +10 extra points
Expert outsourcing transforms every dispute into an NPS improvement opportunity, whereas in-house management merely limits the damage. For a marketplace, this equation is even more critical: a seller who is satisfied with the way his disputes are managed becomes an ambassador for the platform.

Conclusion: From Constraint to Competitive Advantage
Outsourcing transport dispute management is no longer a question of cost reduction, but of strategic transformation to drastically improve NPS. The absolute grail remains reputation, and in e-commerce, reputation is largely built on the ability to transform a problem into a positive experience.
Expert outsourcing doesn't just maintain a high NPS: it improves it by an average of +25 points, thanks to optimized processes, specialized expertise and a responsiveness impossible to reproduce in-house.
Organizations that succeed in this transformation and significantly improve their NPS share three common characteristics:
- Long-term vision: Investment in improving the customer experience rather than simply optimizing costs
- Expert partner: Choosing a transport specialist vs. a generalist service provider to maximize NPS gains
- Rigorous management: systematic measurement of NPS improvement and continuous optimization
For e-tailers and marketplaces managing more than 4,000 parcels a month, outsourcing represents a unique opportunity to transform a €270,000 cost center into a €51,000 investment, generating an additional €288,000 in sales thanks to improved NPS.
The question is no longer "should we outsource?" but "with whom and how can we maximize NPS gains?". In this context, specialized solutions like Claisy, which combine transport expertise, advanced technology and an obsession with NPS improvement, offer the surest route to this transformation.
