If Stripe Radar (has a small fee per transaction) is enabled in an account, then an early warning (before chargeback) is sent via the `radar.early_fraud_warning.created` webhook event, which can be used for a pre-emptive manual review, or an automatic refund and cancellation. No dispute fee on a refunded transaction! There are services like Chargeblast, ByeDispute etc. which also help avoid disputes and chargebacks.
