The Visa Dispute Monitoring Program, sometimes known as VDMP, is a program run by Visa with the aim of limiting the number of chargebacks issued. A merchant will be added to the program if their monthly chargeback volume reaches the Visa-set criteria. Punitive fines, operating limitations, and pricey annual evaluations will follow.
Entry into the Visa Dispute Monitoring Program is similar to a "probation period" for merchants, much like the analogous Visa Fraud Monitoring Program (VFMP). This indicates that, based on the volume of chargebacks made against you in the preceding month, Visa has determined that your current conduct is dangerous.
