Understanding Chargebacks: Why Customers File and How Merchants Lose

Chargebacks occur when customers dispute transactions through their bank, often for "item not received" (INR), fraud, or quality issues. In 2026, fraud accounts for 70% of claims, per Mastercard reports, but friendly fraud (legit customers exploiting policies) makes up 30%.

Merchants lose 60-80% of disputes due to poor evidence or missed deadlines. Mini Case Study: An e-commerce apparel seller lost a $500 INR claim because they submitted only a shipping label--no POD photo. The bank sided with the customer. Lesson: Always include GPS-verified delivery proof.

How Customers Lose Chargebacks: Banks overturn 40% when merchants prove delivery or matching IP data. Visa reports 65% of INR claims reversed with tracking.
