BNPL Dispute vs Chargeback: Key Differences and When to Use Each

BNPL disputes are internal provider processes; chargebacks are bank-mediated via card networks. Use disputes first--chargebacks risk account closure.

Per CFPB/FTC, chargebacks work for fraud but providers like Affirm contradict by treating BNPL as loans, not cards. Start with dispute.
