Common Seller Disputes with Buyers in 2026: Types and Triggers
Disputes spike from multi-party marketplaces (Rapyd/Code23). Top types:
- Product Dissatisfaction: Defects, unmet expectations (e.g., "not as described").
- Delivery Issues: Late/non-delivery, damage (transit woes).
- Payment/Chargebacks: Unauthorized, forgotten buys (8 Rapyd triggers: confusing descriptors, slow seller replies).
- Refunds/Returns: Disputes over eligibility (Markko/Code23).
Stats: Chargebacks from unrecognizable line items (multiple sellers/fees) lead to "forgotten" claims (Rapyd). Case Study: Marketplace buyer disputes $200 refurbished phone chargeback due to "unknown merchant"--seller wins with tracking + comms proving delivery.
Preempt: Use detailed listings ("genuine full-grain leather," eDesk).
