The Impact of Ethoca Alerts on VAMP Ratios
VAMP Ratios Under the Unified Framework
Since June 2025, Visa has calculated the VAMP ratio by combining all reported fraud (TC40 data) with all processed disputes (TC15 data across categories 10, 11, 12, and 13) and dividing that total by settled card-not-present VisaNet transactions (TC05). This replaced the legacy structure where fraud and non-fraud disputes were tracked under separate programs, the Visa Fraud Monitoring Program (VFMP) and the Visa Dispute Monitoring Program (VDMP).
For MSPs, the implications are significant. A single ratio now captures everything. Every fraud report and every dispute, regardless of category, feeds the same calculation. The acquirer-level “Above Standard” threshold sits at 50 basis points, with the “Excessive” threshold at 70 basis points. At the merchant level, the “Excessive” threshold dropped from 220 basis points to 150 basis points in key regions as of April 2026.
That tightening forces MSPs to evaluate portfolio risk differently. It is no longer sufficient to monitor chargeback ratios alone. VAMP ratios demand visibility into total dispute and fraud activity at the descriptor level.
Where Ethoca Alerts Fits in the VAMP Calculation
Ethoca Alerts operates as a pre-chargeback notification system. When a cardholder initiates a dispute with their issuing bank, participating issuers generate an alert that is routed to the enrolled merchant or their service provider. That alert creates a response window, typically around 24 to 72 hours, during which the dispute can be resolved with a refund before a formal chargeback is filed.
From a VAMP ratio perspective, this matters because of what it prevents. If a dispute is resolved through an Ethoca Alert before the chargeback is processed, no TC15 is generated. That means the dispute component of the VAMP ratio is not impacted. Visa has confirmed that disputes resolved through pre-dispute solutions, including Ethoca Alerts, are excluded from the VAMP ratio calculation.
But there is a critical nuance that MSPs need to understand.
The TC40 Factor
Ethoca Alerts can prevent a chargeback. They cannot prevent a TC40 fraud report. If the issuing bank has already filed a TC40 associated with the disputed transaction, resolving the alert removes the TC15 but does not remove the TC40 from the VAMP ratio.
This distinction is essential for MSPs managing fraud-heavy merchant segments. In verticals like online gaming, digital goods, or subscription services, a meaningful percentage of disputes carry associated TC40 reports. Resolving those alerts still provides value by eliminating the chargeback, its fees, and its operational burden. But the fraud signal persists in the VAMP calculation.
So while Ethoca Alerts delivers reliable protection against the dispute component of vamp ratios, MSPs need complementary strategies to address the fraud component. Compelling Evidence 3.0, for example, can qualify TC40 fraud for exclusion when specific data-matching criteria are met.
VAMP ratios combine all fraud reports and dispute activity into a single metric, and for MSPs managing large merchant portfolios, exposure can compound quickly across descriptors and acquiring relationships. Ethoca Alerts can reduce the dispute component by resolving cases before TC15 records are generated, but TC40 fraud reports persist regardless. Understanding which part of the ratio each solution addresses is critical to building an effective compliance strategy. Our Free VAMP Toolkit breaks down exactly how the calculations work, where ratio exposure tends to accumulate, and which layered strategies have the most impact at portfolio scale.

Portfolio-Wide Alert Management for MSPs
Individual merchants may deploy Ethoca Alerts as a standalone prevention layer. MSPs cannot afford that approach. When you are responsible for hundreds or thousands of merchant descriptors across multiple acquiring relationships, alert management requires centralized orchestration.
This is where scalability becomes a competitive differentiator.
An MSP that integrates Ethoca Alerts across its entire portfolio gains two advantages. First, consistent alert coverage reduces the likelihood that any single merchant descriptor exceeds VAMP thresholds and triggers acquirer-level scrutiny. Second, centralized reporting provides the analytics needed to identify which merchants, verticals, or descriptor categories are contributing disproportionately to portfolio risk.
Without that centralization, alert management fragments. Response times vary. Some merchants resolve quickly. Others miss the window entirely. And the portfolio-level VAMP ratio absorbs the inconsistency.
Layering Ethoca Alerts With Complementary Solutions
Ethoca Alerts addresses the pre-chargeback stage. But VAMP ratios reflect the full spectrum of fraud and dispute activity. A comprehensive strategy for managing vamp ratios requires layered coverage across the dispute lifecycle.
At the point of inquiry, before a cardholder even initiates a dispute, enriched transaction data can reduce confusion and interrupt first-party fraud. Order Insight and Consumer Clarity both serve this function by sharing fulfillment details, merchant branding, and purchase data with issuer platforms and banking applications. For MSPs, deploying these capabilities across a portfolio reduces the volume of inquiries that escalate into disputes in the first place.
At the alert stage, Ethoca Alerts and Verifi CDRN provide parallel notification pathways. Running both ensures broader issuer coverage, since each network’s participating issuers differ. Visa RDR adds another layer of automated resolution by applying pre-configured refund rules at the moment a Visa dispute is filed.
And when chargebacks do occur despite preventive measures, structured representment becomes the recovery mechanism. Automated evidence assembly and reason-code-aligned rebuttals allow MSPs to pursue recoverable revenue without adding operational overhead.
Each layer addresses a different point in the lifecycle. Together, they create a coordinated framework that keeps vamp ratios below enforcement thresholds while preserving revenue and reducing unnecessary refund exposure.
Quantifying the Impact Across a Portfolio
Consider the math at scale. An MSP managing a portfolio that generates 50,000 card-not-present transactions per month across a given acquiring relationship needs to keep combined fraud and dispute counts below 750 events to stay under the 150 basis point merchant threshold.
If that portfolio averages 400 non-fraud disputes and 200 TC40 fraud reports per month, the combined count of 600 keeps the ratio at 120 basis points. Still within tolerance, but with limited margin.
Now suppose dispute volume increases by 25% due to seasonal activity, promotional surges, or a shift in customer behavior. Non-fraud disputes climb to 500. Combined with the 200 TC40 reports, the ratio reaches 140 basis points. One more surge and the portfolio crosses the threshold.
Ethoca Alerts, effectively deployed, could potentially resolve a meaningful portion of those non-fraud disputes before they generate TC15 records. Reducing the 500 non-fraud disputes to 350 through timely alert resolution would bring the combined count to 550 and the ratio back to 110 basis points. That margin becomes the difference between compliance and remediation.
Those numbers are illustrative, but the principle is concrete. Alert-based resolution at scale compresses the dispute component of vamp ratios in a way that is both measurable and predictable.
Operational Considerations for MSPs
Deploying Ethoca Alerts at portfolio scale introduces operational requirements that go beyond simple enrollment. MSPs should evaluate several factors.
First, response time discipline. Ethoca Alerts provide a limited window. If internal workflows cannot consistently process and resolve alerts within that timeframe, the preventive value degrades. Automation and managed alert services address this by removing manual bottlenecks.
Second, alert-to-transaction matching. Accurate resolution depends on connecting each alert to its source transaction. Without direct integration between the alert feed and the merchant’s transaction records, refund decisions are made with incomplete context. That increases the risk of unnecessary refunds on one side and missed resolution windows on the other.
Third, analytics and threshold monitoring. MSPs need real-time visibility into which descriptors and merchants are trending toward VAMP thresholds. Reactive monitoring that relies on monthly reports creates blind spots. By the time a threshold breach appears in a report, fees and remediation requirements may already be in effect.
And fourth, strategic refund logic. Not every alert should result in an automatic refund. Transactions associated with repeat abuse, suspected first-party fraud, or high-value orders may warrant review before resolution. The goal is to reduce vamp ratios without encouraging cardholder behavior that increases long-term dispute volume.
The Compliance Advantage
MSPs that treat Ethoca Alerts as a core component of their VAMP compliance strategy position themselves differently in the market. Acquirers are under increasing pressure from Visa to manage portfolio-level risk. An MSP that can demonstrate consistent VAMP ratio management, supported by integrated alert coverage and transparent reporting, becomes a lower-risk partner.
That positioning has downstream effects. Lower risk translates to more favorable terms, fewer remediation demands, and stronger acquiring relationships. It also becomes a sales differentiator. Merchants evaluating service providers increasingly ask about chargeback management capabilities. An MSP that offers automated alert resolution, real-time ratio monitoring, and layered dispute prevention answers that question with substance rather than promises.

FAQs: The Impact of Ethoca Alerts on VAMP Ratios
How do Ethoca Alerts affect vamp ratios?
Ethoca Alerts resolve disputes before they escalate into chargebacks, which prevents TC15 records from being generated. Since TC15s are a component of the VAMP ratio calculation, timely alert resolution directly reduces the dispute portion of the ratio. ChargebackHelp integrates Ethoca Alerts into a managed workflow so MSPs can automate resolution across their entire portfolio.
Do Ethoca Alerts remove TC40 fraud reports from the VAMP ratio?
No. Ethoca Alerts prevent chargebacks but do not remove TC40 fraud reports that the issuing bank has already filed. The TC40 will still count toward the VAMP ratio. For fraud-specific exclusions, Visa’s Compelling Evidence 3.0 provides a pathway when matching criteria are met. ChargebackHelp can help MSPs deploy CE3.0 alongside alert-based solutions for broader ratio protection.
What is the current VAMP ratio threshold for merchants?
As of April 2026, the merchant “Excessive” threshold in key regions including the U.S., Canada, and the EU dropped to 150 basis points. Acquirer-level thresholds remain at 50 basis points for “Above Standard” and 70 basis points for “Excessive.” ChargebackHelp provides real-time monitoring to help MSPs track performance against these thresholds across all merchant descriptors.
Should MSPs refund every Ethoca Alert automatically?
Not necessarily. While many alerts are best resolved with a timely refund, transactions tied to suspected first-party fraud, repeat abuse, or high-value orders may benefit from additional review. ChargebackHelp helps MSPs configure alert rules that balance ratio protection with revenue preservation at portfolio scale.
Can Ethoca Alerts and Verifi CDRN be used together?
Yes. Running both provides broader issuer coverage since each network’s participating issuers differ. Combined deployment ensures that more disputes are intercepted before they become chargebacks. ChargebackHelp consolidates both alert feeds into a single platform through RESOLVE, simplifying management and improving response consistency.
How does VAMP enforcement work for acquirers?
Visa monitors acquirer portfolios monthly and identifies those exceeding program thresholds. Acquirers classified as “Above Standard” or “Excessive” face per-event fees and are required to implement risk mitigation measures. ChargebackHelp works with MSPs to reduce portfolio-level risk exposure before acquirer enforcement actions are triggered.
What other solutions complement Ethoca Alerts for VAMP compliance?
A comprehensive VAMP strategy layers multiple solutions. DEFLECT shares enriched transaction data at the point of inquiry to reduce disputes upstream. RESOLVE consolidates alert management across Ethoca Alerts, Verifi CDRN, and Visa RDR. RECOVER automates representment for chargebacks that warrant recovery. ChargebackHelp integrates all of these into a single platform built for portfolio-scale MSP operations.
