Chargeback alerts are notification services that warn a merchant when a customer begins a dispute, before it becomes a formal chargeback, giving a 24 to 72 hour window to issue a refund and prevent the chargeback entirely. Ethoca, owned by Mastercard, covers Mastercard issuers, and Verifi CDRN, owned by Visa, covers Visa issuers. Most merchants need both for full coverage, because the networks split by card brand. Alert fees typically run $17 to $30 per alert, against a dispute fee of $15 to $30 plus the transaction amount, and alerts can prevent 30 to 40 percent of chargebacks.
Two networks, one window, and a refund that stops the clock
There are only two real alert networks. Ethoca is owned by Mastercard, and Verifi is owned by Visa, and every consumer-facing brand in this market is buying from one or both and marking it up. When a customer contacts their bank to dispute a charge, the bank does not immediately process the chargeback. There is a brief window, typically 24 to 72 hours, before the dispute becomes formal. Ethoca alerts fire on Mastercard issuers, with an objective of acting within 24 hours, and Verifi CDRN gives about 72 hours on Visa. Refund inside the window and the chargeback never posts. Miss it and the dispute becomes a chargeback with a fee attached.
The economics are straightforward on a single order. Take an $80 order about to be disputed, with a $25 dispute fee, and compare the two paths. Refund on the alert and you lose the sale and pay the alert fee, which runs $18 to $29 for Ethoca and around $12 to $19 for Visa's Rapid Dispute Resolution. Let it become a chargeback and you lose the sale, pay the dispute fee, and take the ratio damage. One prevented dispute can pay for several alerts, if the SKU margin supports refund-first logic, and for most merchants it does. The alert fee is only one line, though: you have still refunded the sale, eaten the product and shipping, and paid to acquire a customer who disputed you.

The VAMP catch that the sales pages skip
Here is the part the alert providers do not put in the headline. Under Visa's VAMP program, alerts from Ethoca, CDRN, and RDR still count toward the merchant's VAMP ratio, because the TC40 fraud report is filed even when the chargeback itself is prevented. The alert prevents the chargeback, not the fraud report, and the ratio is computed from the report. Only Order Insight, the pre-dispute inquiry tool that shares order data with the issuing bank before a dispute exists, can potentially prevent TC40s, because it resolves the inquiry before it becomes a dispute at all. Verifi says Order Insight stops about 40 percent of chargebacks at that earlier stage.
The VAMP thresholds effective April 1 2026 put a merchant in the excessive band at a 1.5 percent ratio with at least 1,500 combined fraud and dispute records in a month, and enforcement is reported at roughly $8 per record above the threshold. That means a merchant can buy every alert on the market, prevent every chargeback, and still land in the excessive band, because the ratio counts the reports, not the chargebacks. Alerts are essential but not a complete shield, and a merchant who buys alerts to fix a ratio problem is buying the wrong tool for the job. The ratio is fixed by stopping the disputes from being filed, which is Order Insight's job, not the alert's.
Manual, automatic, and the coverage gap
Ethoca and CDRN are manual: someone on the merchant's side reviews each alert and decides whether to refund. Visa's Rapid Dispute Resolution is automatic: the merchant sets rules, such as refunding disputes under a dollar amount or in certain categories, and the system acts without human review, deciding a case in as little as one second. Most merchants need both the manual alerts and the automatic resolution, because the manual queue catches the cases that need judgment and the automatic rules catch the ones that do not. Neither covers 100 percent of BINs on its network, so even full coverage leaves gaps.
The practical setup is to run both networks, set RDR rules for the low-value disputes that should always be refunded, and review the manual alerts daily, because the window is measured in hours. A merchant processing $1 million a month at a 1.5 percent chargeback rate has roughly $15,000 of revenue in disputes every month, and a third of that is preventable with alerts. The alert program pays for itself on the prevented fees alone, and the ratio benefit, partial as it is, is a bonus. The mistake is treating alerts as the whole prevention strategy, when they are the last warning before the chargeback, not the first line of defense.
Frequently asked questions
What is the difference between Ethoca and Verifi CDRN?
Ethoca is owned by Mastercard and alerts on disputes from Mastercard issuers, with an objective of acting within 24 hours. Verifi CDRN is owned by Visa and covers Visa issuers, with about 72 hours to refund. Most merchants need both for full coverage.
How much does a chargeback alert cost?
Published price points run from $17 to about $30 per delivered alert, depending on network and volume, plus a monthly platform fee from most providers. A dispute fee runs $15 to $30 per chargeback, usually charged win or lose.
Do chargeback alerts fix my VAMP ratio?
Not fully. Alerts from Ethoca, CDRN, and RDR still count toward the VAMP ratio because the TC40 fraud report is filed even when the chargeback is prevented. Only Order Insight, which resolves the inquiry before a dispute exists, can potentially prevent TC40s.
What is Visa Rapid Dispute Resolution?
It is an automated product that refunds qualifying disputes per pre-set rules, such as disputes under a dollar amount, without manual review. A case can be auto-decisioned in as little as one second, which makes it the right tool for low-value disputes.
