Step-by-Step Guide to Building AI Agents for Chargeback Management

Phase 1: Chargeback Analysis & Strategy Development

Step 1: Comprehensive Chargeback Audit

Begin by analyzing your historical chargeback data to understand patterns, reason codes, and win/loss rates across different transaction types and customer segments. This analysis forms the foundation for training your AI agents and developing effective dispute strategies.

Key Analysis Activities

• Reason Code Analysis: Categorize chargebacks by reason codes and identify the most common dispute types
• Win Rate Assessment: Calculate win rates by reason code, transaction amount, and evidence type
• Timeline Analysis: Map response times versus success rates to optimize agent timing
• Evidence Mapping: Document what evidence types are most effective for each chargeback category
• Fraud Pattern Identification: Identify common fraud indicators and customer behavior patterns
• Cost Impact Analysis: Calculate the full cost of chargebacks including fees, lost revenue, and processing time
• Volume Projections: Analyze seasonal trends and growth patterns to plan agent capacity

Strategic Framework Development

Develop a strategic framework that defines when to fight chargebacks versus when to accept them based on win probability, cost-benefit analysis, and customer lifetime value. This framework guides AI agent decision-making and ensures optimal resource allocation.

Data Requirements Planning

• Transaction Data: Payment details, amounts, timestamps, merchant categories
• Customer Data: Purchase history, account age, geographic location, device information
• Dispute History: Previous chargebacks, outcomes, evidence submitted, response times
• Fraud Signals: Velocity checks, IP analysis, device fingerprinting, behavioral patterns
• Evidence Repository: Receipts, shipping confirmations, communication logs, terms of service
