A buyer claims the order never arrived; the seller swears it was shipped. No proof, support drowns in email chains, resolution drags on for weeks. For a marketplace, every such dispute costs time, money, and trust. We built a dispute and arbitration system that automates up to 70% of conflicts and cuts resolution time to 48 hours. Over 5 years, we've delivered 50+ projects, and average dispute processing time dropped 5x compared to manual moderation. Automated returns handling reduces processing time by 60% (source: Stripe).
Problems the System Solves
- Incorrect dispute types: buyers often pick the wrong type, slowing things down. Our system validates data and suggests the correct scenario.
- Slow seller responses: if a seller doesn't reply within 48 hours, the dispute auto-resolves in the buyer's favor for clear cases (non-receipt, return refusal). This motivates fast action.
- Fraud: limit of 3 disputes per month per buyer, scoring based on dispute history, extra scrutiny for sellers with a dispute rate >5%.
How the Dispute System Works
Data Model
disputes ( id, order_id, buyer_id, seller_id, type: not_received | wrong_item | damaged | not_as_described | return_refused, status: open | waiting_seller | waiting_buyer | escalated | resolved_buyer | resolved_seller | resolved_partial | closed, desired_resolution: full_refund | partial_refund | replacement | return_and_refund, requested_amount (for partial_refund), created_at, resolved_at, auto_close_at ) dispute_messages ( id, dispute_id, sender_type: buyer | seller | admin, sender_id, message, attachments (jsonb), created_at ) dispute_evidence ( id, dispute_id, uploaded_by, type: photo | video | document, file_url, description, created_at ) Automatic Resolution Steps
- Buyer opens a dispute, selecting one of five types, and attaches evidence.
- System notifies the seller — they have 48 hours to respond.
- If the seller doesn't respond, the dispute automatically closes in favor of the buyer for types
not_receivedandreturn_refused. - If parties can't agree, the dispute is escalated to an arbitrator.
- The arbitrator reviews the conversation, evidence, and issues a final decision.
Manual vs. Automated Processing
| Parameter | Manual Processing | Automated System |
|---|---|---|
| Average resolution time | 5–7 days | up to 2 days |
| Support load | high | reduced by 40% |
| Error rate | up to 15% | less than 2% |
Automation is 5x faster than manual handling. Manual processing each dispute requires a moderator to verify evidence, communicate with parties, and make a decision — averaging 5–7 days. The automated system resolves obvious cases in 48 hours without human intervention, and for complex cases, the arbitrator gets the full picture in 10 minutes. Time savings of 80%.
Why Abuse Protection Is Critical
- A buyer can open at most 3 disputes per month.
- Dispute history is factored into scoring new users.
- Sellers with a dispute rate >5% of orders are placed under special monitoring.
- Evidence is stored for 180 days after dispute closure.
Example: a buyer ordered a smartphone for 25,000 RUB. 10 days after the expected delivery date, they open a dispute with type not_received. The seller doesn't respond within 48 hours — the system automatically refunds the full amount. The money is deducted from the seller's hold. The entire process takes 2 days without support involvement.
Technical Details: Financial Operations and Analytics
- Full refund: full amount + shipping cost (avg. 300 RUB). Deducted from seller's balance.
- Partial refund: agreed amount, remainder to seller.
- Ruling in favor of seller: money from hold transferred to seller.
- Replacement: hold retained until receipt of replacement confirmed.
All operations are atomic — balance change and dispute status update in a single transaction.
The arbitrator's workspace is a dedicated interface in the admin panel with dispute chronology, order summary, evidence, interaction history, and notification templates. Metrics: average resolution time, percentage of appealed decisions, quality rating.
Dispute analytics: data analysis helps identify problematic categories — the top 3 dispute reasons account for 60% of all cases. Sellers with abnormal dispute rates are candidates for review. Dispute-to-refund conversion rate is an indicator of system fairness.
Development Phases and Timelines
| Phase | Duration | Owner |
|---|---|---|
| Direct negotiation | up to 5 days | Buyer, Seller |
| Automatic resolution | 48 hours | System |
| Escalation to arbitrator | up to 72 hours | Arbitrator |
The full development cycle of a dispute system with arbitration interface, financial operations, and analytics takes 6 to 8 weeks. Timelines may vary depending on integration complexity and business logic requirements.
