Pre dispute alerts exist because a refund made before a chargeback is filed is cheaper than a chargeback in almost every way. You avoid the dispute fee, you avoid the work of a response, and in most cases the event does not count against your dispute ratio. The three main programs reach that result through different routes, with different card coverage and different time pressure. This article explains each one, compares them side by side and shows how to combine them.
How Ethoca alerts work
Ethoca is a collaboration network owned by Mastercard that connects card issuers with merchants. When a cardholder tells a participating issuer that a transaction is fraudulent or disputed, the issuer can send an alert through Ethoca to the merchant. The alert carries the transaction details so the merchant can find the order.
The merchant then decides what to do. The usual action is to refund the transaction and, for physical goods, stop the shipment if it has not left. When the refund is made in time, the issuer does not need to file a chargeback. Ethoca alerts cover cards from participating issuers rather than a single network, so they reach Mastercard cards and a share of Visa and other cards, depending on which issuers take part.
-
Two kinds of alerts exist, confirmed fraud alerts and customer dispute alerts.
-
The merchant must act within a short window, commonly between 24 and 72 hours.
-
Some alerts arrive after the issuer has already filed the chargeback, and those cannot be stopped with a refund.
Our Ethoca alerts page explains how NoChargeback routes these alerts and applies your refund rules.
How Verifi CDRN works
Verifi is owned by Visa. Its Cardholder Dispute Resolution Network, known as CDRN, works on the same principle as Ethoca. A participating issuer sends a notice when a cardholder disputes a transaction, the merchant reviews it and can issue a refund within the response window, which is commonly 72 hours. If the merchant refunds, the issuer closes the case without a chargeback.
CDRN coverage depends on which issuers participate. Many large US issuers do, and the network reaches cards from more than one brand, but coverage overlaps only partly with Ethoca. That partial overlap is the main reason merchants subscribe to both.
How Verifi RDR works
Rapid Dispute Resolution, known as RDR, is different in design. It is built into Visa's dispute flow, so it covers Visa transactions broadly rather than only cards from issuers who joined a separate network. You do not receive an alert to act on. Instead, you set rules in advance, such as amount limits, reason codes, card ranges or product types. When an issuer starts a Visa dispute, RDR checks your rules in real time. If a rule says refund, the transaction is credited automatically and no dispute is created.
Because the decision is automatic, RDR has no response window to miss. The tradeoff is that you must decide your rules carefully. A rule that is too broad refunds disputes you could have won, and a rule that is too narrow lets avoidable disputes through. A dispute resolved through rapid dispute resolution does not count as a dispute in Visa's monitoring, which is why RDR is central to staying under Visa VAMP.
Where Order Insight fits
Verifi Order Insight is not an alert but a data sharing tool. When a cardholder calls the issuer about a charge they do not recognize, the issuer can see your order details, such as the product, the delivery address and the merchant contact. Many inquiries end there because the cardholder remembers the purchase. Order Insight is also the route through which Visa Compelling Evidence 3.0 data can stop a qualifying fraud dispute before it is filed. Mastercard offers a comparable data sharing service through Ethoca.
Ethoca vs Verifi CDRN vs RDR side by side
The table summarizes how the three programs differ at the time of writing. Coverage and response windows change as issuers join or leave, so check current details with your provider.
| Feature | Ethoca alerts | Verifi CDRN | Verifi RDR |
|---|---|---|---|
| Owner | Mastercard | Visa | Visa |
| How it works | Issuer sends an alert, merchant refunds | Issuer sends an alert, merchant refunds | Rules decide in real time and refund automatically |
| Card coverage | Cards from participating issuers across networks | Cards from participating issuers across networks | Visa transactions |
| Time to act | Short window, often 24 to 72 hours | Short window, commonly 72 hours | No window, the decision is instant |
| Manual work | Review or automate each alert | Review or automate each alert | Set and tune the rules |
| Risk of a missed case | Alert ignored or late | Alert ignored or late | Rule too narrow |
| Main benefit | Reaches Mastercard disputes and fraud reports | Covers issuers outside Ethoca | Broad Visa coverage with no deadline |
What alerts cost and how to think about it
Every alert program charges per alert or per resolved case, and the price depends on the provider, your volume and your contract. Because pricing changes often, we do not quote numbers here. The useful comparison is not the alert price by itself but the alert price against the full cost of a chargeback: the lost sale, the processor dispute fee, the staff time, and the effect on your ratio and your relationship with the acquirer.
For low value orders, an alert can cost more than the order. In that case it can still be worth paying for if your ratio is close to a network threshold, because the ratio risk outweighs the single order. When your ratio is comfortable, you can set rules that skip alerts or RDR refunds below a chosen amount and fight those disputes instead.
Which pre dispute alerts a merchant needs
The right mix depends on your card mix, your ratio and your margins. A practical way to decide is to look at where your disputes come from.
- 1 Pull six months of disputes and split them by network and by issuer.
- 2 If Visa disputes dominate, start with RDR, because it covers Visa broadly and needs no manual action.
- 3 Add Ethoca to reach Mastercard disputes and fraud reports from participating issuers.
- 4 Add CDRN to cover issuers that sit outside Ethoca.
- 5 Turn on Order Insight so issuers can resolve unrecognized charges and qualifying fraud cases before a dispute starts.
- 6 Review the results monthly and adjust refund rules by amount, reason and product.
Merchants with very low dispute volume may not need every program. Merchants close to a Visa or Mastercard threshold almost always do, because the cost of losing a merchant account is far higher than the cost of the alerts.
How to set RDR rules without giving away winnable cases
RDR rules are only as good as the data behind them. Start from your own dispute history, not from a default. Look at which reason codes you win and which you lose, and at which amounts the effort of a response stops paying off.
-
Refund automatically when the amount is below the level where a response is worth the time and fees.
-
Refund automatically on reason codes where you rarely win, such as fraud claims on digital goods with no account history.
-
Do not refund automatically on reason codes where you hold strong evidence, such as delivered orders with signature or heavy product usage.
-
Treat customers with earlier undisputed orders separately, because a fraud claim on their purchase may qualify for Compelling Evidence 3.0.
-
Review the rules every month and after any change in pricing, products or checkout.
The same logic applies to automated responses for Ethoca and CDRN alerts. One rule set for all three programs keeps decisions consistent and makes the results easy to compare.
Avoid paying twice for the same dispute
Ethoca and CDRN coverage overlap for some issuers, so the same dispute can trigger two alerts. RDR can also act on a Visa dispute that already produced an alert. Without deduplication you may refund twice or pay for two alerts on one order. A good alert setup matches each alert to the order, checks whether it was already refunded, and records which program resolved the case.
Measure whether your alerts work
Track three numbers every month: the share of disputes that arrived with an alert first, the share of alerts you resolved inside the window, and the disputes that still reached you without any warning. A low share of alerted disputes points to coverage gaps, which usually means adding a program. A low resolution rate points to slow handling, which usually means more automation.
Automate the response so no alert is missed
The weak point of Ethoca and CDRN is the response window. An alert that arrives on Friday evening and waits until Monday is a chargeback. Automate the decision with rules: refund automatically below a set amount, refund all confirmed fraud alerts for digital goods, cancel the subscription when the alert relates to a recurring charge, and send higher value cases to a person.
NoChargeback combines Ethoca, CDRN and RDR in one place with the same rule engine, and passes every case that becomes a dispute anyway to automated chargeback management. Put together, that is the chargeback prevention layer that stops avoidable disputes and leaves your team to fight the ones worth winning. You can see what each plan includes on our pricing page.
Check a dispute before you decide to refund
Pick the reason code and the evidence you hold. NoChargeback estimates the win chance so you know whether to refund through an alert or fight.
Is Ethoca better than Verifi CDRN?
Neither is better in general. They reach different sets of issuers, so each catches disputes the other misses. Merchants with meaningful dispute volume usually use both, plus RDR for Visa.
Does RDR work for Mastercard transactions?
No. RDR is a Visa program built into the Visa dispute flow. Mastercard disputes are covered by alerts from Ethoca and by issuers that participate in CDRN.
Do I lose the sale when I refund through an alert?
Yes, you refund the transaction. You avoid the dispute fee, the response work and in most cases the dispute record, which is usually worth more than defending a weak case.
Can an alert arrive after the chargeback is filed?
Yes. Some alerts are sent after the issuer has already filed a chargeback. Refunding in that case does not stop it and can lead to paying twice, so check the alert status before you refund.
