Today we are talking about the Visa Acquirer Monitoring Program and the latest updates that merchants need to understand before enforcement begins.
Visa has introduced major changes to its monitoring systems through the updated VAMP framework. The Visa Acquirer Monitoring Program now combines fraud monitoring and dispute monitoring into a unified structure that changes how merchants and acquirers measure risk.
For ecommerce merchants and payments teams, these changes are significant. The new rules affect how fraud ratios are calculated, how disputes are counted, and how monitoring thresholds are applied across acquirer portfolios.
In this episode I break down what the updated Visa Acquirer Monitoring Program means for merchants, how VAMP threshold changes will affect fraud monitoring, and what steps organizations should take to prepare for October 2025 VAMP enforcement.
Understanding these changes now will help merchants avoid unexpected fees, monitoring program escalations, and operational disruptions later.
What you’ll hear in this episode
- How the Visa Acquirer Monitoring Program consolidates fraud and dispute monitoring
- What VAMP threshold changes mean for merchant fraud ratio reduction
- Why double counting fraud disputes is creating confusion for merchants
- How the new Visa dispute fee structure affects ecommerce payments fraud management
- What prevention tools under VAMP can help merchants reduce monitoring risk
- Why acquirer collaboration for VAMP is critical for compliance

Episode notes & key takeaways
Why the Visa Acquirer Monitoring Program is changing
Let’s reset the room for a moment.
The Visa Acquirer Monitoring Program has historically tracked merchant risk through separate monitoring systems. One program focused on fraud rates, while another focused on dispute activity.
With the introduction of VAMP, Visa is consolidating those programs.
This fraud and dispute monitoring consolidation means merchants must now monitor both fraud alerts and disputes together rather than managing them independently.
The shift creates a new framework for Visa payments risk program oversight.
Merchants who previously managed acceptable levels in one category may now find themselves approaching thresholds faster under the new combined ratios.
Understanding VAMP threshold changes
One of the most significant elements of the updated Visa Acquirer Monitoring Program is the adjustment to monitoring thresholds.
VAMP threshold changes affect how merchants are categorized within Visa’s risk tiers.
Merchants exceeding certain fraud or dispute levels may enter monitoring programs with escalating requirements, additional oversight, or higher fees.
These excessive fraud thresholds are designed to push merchants toward stronger fraud controls and dispute management processes.
For merchants operating at scale, these thresholds require careful fraud monitoring and ratio management.
Double counting fraud disputes and operational confusion
Another issue generating significant discussion across the industry involves double counting fraud disputes.
Under the new framework, certain fraud alerts and disputes may both contribute to the same monitoring ratio.
This can create confusion for merchants who previously tracked these events separately.
When fraud alerts later become disputes, merchants may see the same incident contribute multiple signals to monitoring metrics.
Understanding how these metrics interact is essential for accurate merchant VAMP preparation.
Prevention tools and merchant preparation
Visa has also introduced new rules around prevention tools under VAMP.
Merchants may use certain chargeback prevention tools and dispute resolution services to help reduce dispute activity.
However, merchants must carefully evaluate how these tools interact with monitoring rules and dispute reporting.
Chargeback prevention under VAMP requires both technology solutions and strong internal processes.
Merchants should ensure their fraud systems, dispute workflows, and reporting processes align with the updated program structure.
Preparing for October 2025 enforcement
Enforcement for the updated Visa Acquirer Monitoring Program is scheduled to begin in October 2025\.
That timeline gives merchants a limited window to review their fraud ratios, dispute volumes, and monitoring exposure.
Merchant preparation should include reviewing fraud prevention systems, improving dispute management strategy for merchants, and coordinating with acquirers to understand portfolio monitoring expectations.
Acquirer monitoring rules will play a major role in how merchants are evaluated under the updated framework.
Strong collaboration with acquiring partners will help merchants navigate these changes more effectively.
The key takeaway from this episode is simple.
The Visa Acquirer Monitoring Program is evolving, and the new VAMP structure changes how fraud and disputes are measured across the payments ecosystem.
Merchants who understand these changes early will be better positioned to manage risk, reduce fraud ratios, and avoid unnecessary monitoring penalties.
Stay vigilant, stay informed, and keep moving fraud forward.
