Chargeback Fundamentals
On this page
Core concepts for understanding the dispute ecosystem.
The Chargeback Lifecycle
Customer Complaint → Issuer Review → Chargeback Filed →
Merchant Notification → Representment (optional) →
Pre-Arbitration → Arbitration → Final Decision
Timeline
| Stage | Timeframe | Action Required |
|---|---|---|
| Dispute Window | 60-120 days from transaction | Customer files with issuer |
| Merchant Response | 20-45 days (network-dependent) | Submit representment |
| Pre-Arbitration | 30-45 days | Issuer challenges response |
| Arbitration | 45-90 days | Network makes final ruling |
Key Concepts
Liability Shift
The party responsible for fraud losses depends on:
- EMV chip presence
- 3D Secure enrollment
- Transaction type (CNP vs. CP)
See EMV Liability Shift for the full matrix.
Compelling Evidence
Documentation that can overturn a dispute:
- Proof of delivery (signed, with tracking)
- Customer communication
- IP/device fingerprint matching
- Previous undisputed transactions
See the full Compelling Evidence Guide for network-specific requirements.
Digital Goods Chargebacks
Digital goods chargebacks are harder to fight because there's no physical delivery to prove. The key evidence for digital: IP at purchase, device fingerprint, download timestamps, account activity logs, and usage after purchase.
For the full evidence strategy (what to collect, how to package it, CE 3.0 requirements for digital), see Digital Goods Evidence.
