For retailers marketplaces (>4,000 packages/month), shipping disputes account for 2-8% of total volume. If poorly managed, they can cause your NPS to drop by 30 points. If properly outsourced, they can improve it by +25 points and turn every incident into an opportunity to build customer loyalty.
NPS goes beyond measuring customer satisfaction and determines how loyal customers are to your brand. In e-commerce, delivery is the last point of contact before the final customer evaluation. NPS on both the buyer and seller sides reveals strong or weak signals about satisfaction, particularly when managing delivery incidents.
This strategic guide is intended for E-commerce Directors, Customer Success Managers, and Marketplace Managers who handle more than 4,000 shipments per month and are looking to transform their transportation dispute management from a cost center into a lever for improving NPS and competitive differentiation.
The Paradox of Transportation Litigation: Between NPS Impact and Management Costs
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, contact with Carrier, 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+ packages/month)
- Average Dispute Rate: 2-8% depending on the sector
- Monthly volume: 80-320 disputes to be handled
- Internal Annual Budget: €72,000 - €384,000
This workload often represents the equivalent of 2-3 FTEs dedicated solely to managing delivery incidents.
The Critical Impact on NPS: The Potential for Improvement
An NPS above 0 is considered a decent satisfaction score, but e-commerce leaders aim for much higher scores. Apple sells its products at a higher price than its competitors but enjoys an 87% customer loyalty rate thanks to its exemplary customer experience, particularly when problems arise.
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 turns every dispute into an opportunity to improve NPS, whereas internal management is content to limit the damage. For a marketplace, this equation is even more critical: a seller who is satisfied with how their disputes are handled becomes an ambassador for the platform.

Conclusion: From Constraint to Competitive Advantage
Outsourcing transport dispute management is no longer a matter of cost reduction, but rather a strategic transformation to drastically improve NPS. The ultimate goal remains reputation, and in e-commerce, this reputation is largely built on the ability to turn a problem into a positive experience.
Expert outsourcing not only maintains a high NPS, it improves it by an average of +25 points thanks to optimized processes, specialized expertise, and responsiveness that cannot be replicated internally.
Organizations that successfully complete this transformation and significantly improve their NPS share three common characteristics:
- Long-Term Vision: Investing in improving the customer experience rather than simply optimizing costs
- Expert Partner: Choosing a transport specialist vs. a general service provider to maximize NPS gains
- Rigorous Management: Systematic measurement of NPS improvement and continuous optimization
For retailers marketplaces handling more than 4,000 parcels per month, outsourcing represents a unique opportunity to transform a cost center of €270,000 into an investment of €51,000, generating €288,000 in additional revenue 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 such as Claisy, which combine transportation expertise, advanced technology, and a focus on NPS improvement, offer the surest path to this transformation.
