Dispute toolkit for peer-to-peer marketplace sellers
Problem
Sellers on Vinted, Depop and similar P2P marketplaces lose disputes automatically: the platform refunds the buyer within hours, lets them keep the item, and answers every appeal with 'our decision is final'. A seller who shipped a £320 tent with photo and weight evidence had to take Vinted to the Scottish small-claims court himself to recover his money, and posted his story because no practical guidance existed for other sellers.
Opportunity
A toolkit for P2P sellers: structured evidence capture (timestamped packing photos, courier weight lookups, drop-off proof) plus a Letter Before Action generator and court-form filing assistant mapped to the seller's jurisdiction, priced as a flat or success fee.
Market analysis
The pain is acute and documented across r/vinted and r/LegalAdviceUK threads, but the legal-document half of the idea is already commoditized (free Citizens Advice templates, CaseCraft AI for small-claims filing). The genuinely uncovered gap is pre-dispute evidence capture built for casual P2P sellers, which no incumbent does.
Market · Casual and semi-pro sellers on Vinted, Depop and eBay in the UK/EU, a large and growing seller base with recurring dispute losses and active community demand for practical guidance.
Pricing · Adjacent comparables: chargeback-recovery firms (Justt, Chargeflow) charge success fees; consumer small-claims tools fit a flat per-claim fee of roughly £15-40, which matches the one-off nature of the purchase.
Pros
- + Acute, emotionally charged pain with viral court-victory stories doing the marketing.
- + Pre-dispute evidence capture (timestamped photos, courier weight proof) is a real gap no incumbent fills for P2P sellers.
- + Flat-fee, one-shot purchase fits how casual sellers actually want to pay.
Cons
- − One-time-use product: every customer is churn, so acquisition cost never amortizes.
- − Letter-before-action and filing help already exist free (Citizens Advice) or cheap (CaseCraft AI).
- − Per-jurisdiction legal mapping (England, Scotland, EU) is heavy lifting for a solo builder.
- − Willingness to pay of casual sellers is low relative to typical dispute values.

The defensible wedge is the evidence half, not the legal half. Letters before action and MCOL filing are already served by free templates and CaseCraft-style tools, and chargeback firms like Justt and Chargeflow cover merchants, not casual Vinted sellers. What no one offers is the habit-forming pre-shipment ritual: timestamped packing photos, courier weight receipts and drop-off proof assembled into a dispute-ready bundle at listing time. That data is the only thing a platform’s automated refund decision cannot wave away, and it converts an unwinnable appeal into a winnable small claim. A solo builder should ship UK-only first (Scotland and England have different small-claims tracks) and treat jurisdiction expansion as a separate product decision.
