Pre-dispute resolution refers to the act of resolving a potential issue before the customer formally raises a dispute against you.
Pre-dispute tools provide you with additional control over your dispute strategy and can help to resolve disputes before they count towards your dispute ratio.
For example, Checkout.com's Rapid Dispute Resolution (RDR) is a pre-dispute tool which can resolve Visa disputes in real-time by accepting liability and refunding the customer when your custom rules are met.
