Ethoca

What is Ethoca (Ethoca Alerts)?

Ethoca is a network for sharing data on disputed card transactions. It is owned by Mastercard, and the Ethoca Alerts product is widely known in the industry. When an issuer receives a cardholder's complaint about a payment, it sends the merchant an alert through the network while the dispute has not yet become a formal chargeback.

## How it works

The issuing bank records a customer complaint, for example "I don't recognize this purchase," and sends an alert to the merchant or its processor. The merchant usually has a limited window to respond by issuing a refund or cancelling the transaction. If the refund is made before a formal chargeback, the case is closed without a chargeback fee and without being counted in dispute statistics.

## Where it applies

In fintech and payments, Ethoca is used by processors and payment gateways connected to the network. In nutra and health products, alerts often come in on subscriptions and recurring charges where the customer does not recognize the descriptor. In dating, alerts are most often tied to paid subscriptions and trial periods.

## Impact

Alerts reduce the share of chargebacks that payment systems and banks consider when assessing risk. The lower that share, the smaller the chance of being placed in monitoring programs. However, a refund issued in response to an alert still costs money and product, so it must be factored into unit economics.

## Common mistakes

The main mistake is ignoring alerts or failing to set up automated handling, which lets the response window expire. The second is refunding alert-triggered disputes without analyzing the causes: if a confusing descriptor or weak onboarding is driving complaints, the problem needs to be fixed, or the flow of alerts will keep growing. The third is not matching alerts against your own transaction logs, which leads to refunds issued for incorrect matches.
