Mastering the Visa VAMP Program: A Merchant’s Guide to Reducing Risk and Avoiding Fees

In the ever-evolving landscape of payment processing, managing fraud and chargebacks has become a paramount concern for merchants and acquirers. These risks have escalated due to the surge in online transactions, which are particularly vulnerable to fraud. In response to this growing challenge, Visa has introduced the Visa Acquirer Monitoring Program (VAMP), a next-generation framework aimed at improving fraud and dispute management.

Starting on April 1, 2025, Visa will retire its existing Visa Fraud Monitoring Program (VFMP) and Visa Dispute Monitoring Program (VDMP) in the Visa Europe region, replacing them with VAMP. This new program combines multiple initiatives under one umbrella and sets stricter guidelines for handling fraud and disputes, marking a significant shift in Visa’s approach to payment processing oversight.The purpose of VAMP is not only to streamline Visa’s existing fraud and dispute programs but also to offer a more robust and unified strategy for merchants and acquirers to mitigate risks associated with payment processing.

It is designed to improve the management of fraud, reduce chargebacks, and ultimately provide a more secure and reliable payment ecosystem. The changes introduced under VAMP will directly affect both merchants and acquirers, requiring them to adhere to new metrics and thresholds to remain compliant with Visa’s expectations. This transition is especially critical as Visa moves toward consolidating fraud and dispute monitoring programs, setting a clear path for how businesses must adapt.

Key Features of the VAMP Program

The Visa VAMP Program incorporates a number of key components that aim to better monitor and manage fraud and dispute activity. These components include the VAMP Ratio, enumeration monitoring, and new compliance thresholds. Each of these elements plays a pivotal role in assessing the performance of acquirers and merchants, as well as their overall risk exposure.

The VAMP Ratio is the cornerstone of the program. It is a metric that measures the ratio of fraudulent and disputed transactions to total settled transactions, providing a clear view of the risk an acquirer or merchant poses in relation to fraud and disputes. Visa will use this ratio to track merchants’ performance and to ensure that both merchants and acquirers are adhering to acceptable standards of fraud and chargeback management. If the VAMP Ratio surpasses certain thresholds, penalties may be imposed.

Enumeration Monitoring focuses on card testing fraud, which is a prevalent issue in the card-not-present (CNP) transaction environment. In card testing, fraudsters test stolen card details by making small-value transactions. If these transactions go unnoticed, they could result in significant financial loss. Enumeration monitoring helps Visa identify and address these types of fraud early, reducing the impact of such fraudulent activities.

Tighter Compliance Thresholds are being introduced to ensure that merchants and acquirers maintain their fraud and dispute levels within acceptable limits. These thresholds are part of Visa’s effort to protect consumers and merchants by holding all parties accountable. By establishing these limits, Visa ensures that businesses are actively managing risk, rather than allowing fraudulent activities or disputes to escalate.

Finally, Visa has adopted Risk-Based Enforcement measures. If an acquirer or merchant exceeds the established thresholds, they may face financial penalties or, in extreme cases, termination from Visa’s network. This is designed to provide a powerful incentive for businesses to stay within the acceptable levels of risk, ensuring that Visa’s global network remains secure and efficient.

Importance of the VAMP Program for Merchants and Acquirers

The introduction of the Visa VAMP Program signifies a substantial shift in the way merchants and acquirers must approach fraud and dispute management. For merchants, understanding how the VAMP Ratio works and ensuring that their performance falls within acceptable thresholds is essential to avoid penalties. The VAMP Program will have a direct impact on their business operations and profitability, as exceeding Visa’s thresholds could lead to hefty fines or, in the worst-case scenario, the termination of their merchant account.

Acquirers, on the other hand, will be held accountable for the performance of their merchant portfolios. If an acquirer’s merchants collectively surpass the VAMP thresholds, the acquirer may face penalties. In addition, acquirers will need to impose stricter limits on merchants who are deemed high-risk to protect their own portfolios. This means that acquirers must have effective risk management strategies in place to manage their merchant relationships and ensure that their portfolios meet Visa’s expectations.

In this context, merchants must work closely with their acquirers to ensure that their fraud prevention and chargeback management systems are aligned with Visa’s new standards. This partnership will be crucial in reducing the likelihood of reaching excessive fraud and dispute levels, thus safeguarding the merchant’s business and financial stability.

Role of Acquirers in the VAMP Program

Acquirers play a pivotal role in the Visa VAMP Program, as they are responsible for monitoring and managing the performance of their merchant portfolios. If an acquirer’s group of merchants exceeds the VAMP thresholds, the acquirer could face penalties. These penalties are structured as follows:

  • $5 per fraudulent or disputed transaction for acquirers whose merchants fall into the Above Standard VAMP Ratio category.

  • $10 per fraudulent or disputed transaction for acquirers whose merchants fall into the Excessive VAMP Ratio category.

Acquirers must stay vigilant about the performance of their merchants, especially those in high-risk industries. By tracking the VAMP Ratios of their merchants and taking proactive steps to reduce fraud and disputes, acquirers can protect themselves from penalties and ensure continued business relationships with Visa.

Why VAMP Matters for Businesses

For merchants, the introduction of the VAMP program means that they will need to invest more in fraud prevention and chargeback management strategies. High levels of fraud or disputes can not only result in financial penalties but can also harm their relationships with acquirers, which may limit their access to payment processing services. The VAMP program is thus a powerful incentive for merchants to improve their payment processes and reduce their exposure to fraud.

Acquirers, on the other hand, must also take the necessary steps to monitor and support their merchants in managing risk. As Visa holds acquirers accountable for the overall performance of their merchant portfolios, acquirers must be proactive in ensuring that their merchants stay compliant with Visa’s new standards. This partnership between acquirers and merchants is critical for reducing fraud, minimizing disputes, and maintaining a healthy financial ecosystem for all parties involved.

Role of the VAMP Ratio in Monitoring Fraud and Disputes

One of the most crucial aspects of the Visa Acquirer Monitoring Program (VAMP) is the introduction of the VAMP Ratio. This metric is designed to provide Visa with a comprehensive overview of how well both merchants and acquirers are managing fraud and disputes. The ratio helps assess the risk exposure of businesses by comparing fraudulent and disputed transactions against the total number of settled card-not-present (CNP) transactions. It is a powerful tool to measure the level of fraud and disputes within a merchant’s operations and a key indicator of risk within an acquirer’s portfolio.

Card-Not-Present (CNP) Transactions and Their Impact on the VAMP Ratio

The VAMP Ratio is specifically relevant to card-not-present (CNP) transactions, which are transactions made without the physical presence of the card. These types of transactions are particularly vulnerable to fraud because card details are entered manually, and no physical verification is possible. Examples include online purchases, phone orders, and transactions through mobile apps. For these types of transactions, merchants face a higher risk of fraud, which is why Visa has placed a significant emphasis on monitoring them.

The focus on CNP transactions reflects the reality of the modern payment ecosystem, where e-commerce and digital payments are becoming increasingly prevalent. As more consumers shop online and conduct business digitally, CNP transactions have become the norm, thus increasing the potential for fraud. By using the VAMP Ratio to track the rate of fraud and disputes in CNP transactions, Visa aims to ensure that businesses take steps to safeguard against these risks and prevent fraudulent activities that could compromise the overall security of its payment network.

For merchants, the key to staying compliant with the VAMP program is to understand the dynamics of CNP transactions and implement strategies to reduce fraud. This includes utilizing tools like 3D Secure authentication, fraud detection algorithms, and transaction monitoring systems that can detect suspicious patterns. As fraud within CNP transactions continues to be a significant concern, taking proactive measures will not only help merchants maintain compliance but also protect their bottom line from the financial repercussions of fraud and chargebacks.

Understanding the Compliance Thresholds: Initial and Future Standards

Visa has established specific compliance thresholds for both merchants and acquirers to ensure that their fraud and dispute levels remain within acceptable limits. These thresholds are a core part of the VAMP program, providing a clear framework for how businesses should manage their risk profiles. By setting these benchmarks, Visa can better monitor merchant and acquirer performance, as well as enforce actions when thresholds are exceeded.

For acquirers, Visa has defined two key thresholds:

  • Above Standard VAMP Ratio: This threshold refers to a higher-than-acceptable ratio of fraud and disputes relative to the total number of transactions. The initial threshold for acquirers, starting on April 1, 2025, is set at N/A, meaning that this metric is not applicable in the first phase of the program. However, in 2026, Visa will introduce an Above Standard VAMP Ratio threshold of 0.3%.

  • Excessive VAMP Ratio: This refers to a significantly elevated level of fraud and disputes within a merchant’s or acquirer’s portfolio. For acquirers, the initial threshold for an Excessive VAMP Ratio is set at 0.5% in 2025, which will remain unchanged in 2026.

For merchants, the thresholds are more specific and are designed to ensure that they do not exceed levels that could jeopardize the integrity of the Visa network. The key thresholds for merchants are:

  • Excessive VAMP Ratio: Merchants who exceed this threshold may face penalties. The initial threshold, starting on April 1, 2025, is set at 1.5%, which will be reduced to 0.9% in 2026. If a merchant’s VAMP Ratio exceeds 1.5%, they will be classified as having an Excessive VAMP Ratio, and penalties will apply.

  • Enumeration: This refers to the percentage of transactions that are identified as card testing fraud, where fraudulent actors test stolen card details. If a merchant’s enumeration rate exceeds 20%, they will be flagged for exceeding the threshold. This threshold remains the same in 2026.

Exceeding these thresholds can lead to serious consequences, including penalties and potential termination from Visa’s network. For example, merchants who exceed the Excessive VAMP Ratio face fees of $10 per fraudulent or disputed transaction. Similarly, acquirers whose portfolios exceed the threshold are subject to fines of $5 per transaction for an Above Standard VAMP Ratio and $10 for an Excessive VAMP Ratio.

These thresholds serve as a mechanism to encourage both merchants and acquirers to maintain lower levels of fraud and disputes in their transaction environments. Exceeding these thresholds signifies a failure to manage fraud effectively and presents a risk to Visa’s broader payment ecosystem. Therefore, businesses must work to stay within the established limits to avoid significant penalties.

Importance of Enumeration Monitoring and Fraud Prevention

One of the unique features of the VAMP program is its focus on enumeration monitoring, which targets card testing fraud. Enumeration fraud occurs when fraudsters attempt small-value transactions to test stolen credit card details before committing larger fraudulent purchases. This type of fraud can be especially difficult to detect and mitigate because the fraudulent transactions tend to be small and often go unnoticed by merchants.

Visa’s introduction of enumeration monitoring is aimed at reducing the impact of these types of fraud. Merchants who are flagged for a high rate of card testing fraud (i.e., exceeding the 20% enumeration threshold) will be subject to increased scrutiny and penalties. In this context, businesses must adopt more sophisticated fraud prevention measures to detect and block these types of transactions.

Effective fraud prevention strategies include implementing real-time fraud detection systems, using address verification systems (AVS), and integrating multi-layered authentication protocols such as 3D Secure. These tools can help merchants identify suspicious transactions early and block potential fraud before it impacts their business. By focusing on these preventive measures, merchants can reduce the risk of fraud and chargebacks, ensuring compliance with Visa’s standards and maintaining a healthy relationship with their acquirers.

Proactive Steps for Staying Compliant with VAMP

To remain compliant with the Visa Acquirer Monitoring Program, merchants must take proactive steps to manage their fraud and dispute levels effectively. This involves a combination of technological solutions, operational improvements, and strategic partnerships.

One of the first steps that merchants should take is to implement fraud prevention tools that can detect and prevent fraudulent transactions in real-time. Real-time fraud detection tools, powered by machine learning algorithms and transaction analytics, can help merchants flag suspicious transactions as soon as they occur. This proactive approach enables merchants to take action before fraudulent transactions are settled, reducing the overall impact on their VAMP Ratio.

Additionally, merchants should invest in chargeback management tools that allow them to track and dispute chargebacks efficiently. By utilizing automated chargeback management systems, merchants can ensure that they respond quickly to disputes and resolve them in a way that minimizes the impact on their VAMP Ratio. This also involves addressing the root causes of chargebacks, such as misleading product descriptions or poor customer service, to reduce future disputes.

Another important step is for merchants to work closely with their acquirer to ensure that they are meeting Visa’s compliance requirements. Acquirers play a significant role in the VAMP program by monitoring the performance of their merchants’ portfolios. Merchants must maintain open communication with their acquirers to understand their fraud and dispute levels, share strategies for reducing fraud, and ensure that they remain in compliance with Visa’s standards.

Finally, merchants should establish clear customer support channels to resolve issues before they escalate into disputes. Proactively addressing customer complaints and offering efficient resolutions can significantly reduce the likelihood of chargebacks, keeping the merchant’s VAMP Ratio in check.

Importance of VAMP Fees and Penalties

As Visa continues to refine the way it manages fraud and disputes within its payment network, the Visa Acquirer Monitoring Program (VAMP) introduces a set of fees and penalties for merchants and acquirers who fail to meet the program’s thresholds. These penalties are a critical part of Visa’s strategy to encourage compliance and to hold both merchants and acquirers accountable for their fraud and dispute levels. The VAMP program sets clear financial consequences for those who exceed the compliance thresholds, making it essential for businesses to understand and manage their fraud and dispute metrics proactively.

The fees associated with non-compliance are designed to incentivize merchants and acquirers to reduce fraud, minimize disputes, and stay within the acceptable risk parameters established by Visa. However, these penalties are not merely punitive; they reflect the increased risk to the Visa payment ecosystem when fraud and chargebacks go unchecked. By imposing fees for high levels of fraud and disputes, Visa ensures that those who put the network at risk contribute to the cost of managing these issues. This, in turn, helps to maintain the security and integrity of the global payment system.

Fees for Acquirers and Merchants Under the VAMP Program

For both acquirers and merchants, exceeding Visa’s established thresholds results in specific fees. These fees are based on the nature and extent of the non-compliance, specifically when fraud and disputes surpass the set limits for the VAMP Ratio or enumeration monitoring.

Acquirer Fees

Acquirers are financial institutions or payment processors responsible for managing the merchant accounts within their portfolio. When an acquirer’s portfolio exceeds the established fraud and dispute thresholds, they face the following fees:

  • $5 per fraudulent or disputed transaction for an Above Standard VAMP Ratio: This fee applies when the acquirer’s portfolio exceeds the upper acceptable limit for fraud and dispute levels, falling into the “Above Standard” category as defined by Visa. This penalty is intended to encourage acquirers to manage their merchant portfolios effectively and to minimize the risk associated with their merchant base.

  • $10 per fraudulent or disputed transaction for an Excessive VAMP Ratio: The more severe penalty occurs when the acquirer’s portfolio exceeds Visa’s Excessive VAMP Ratio threshold. This higher fee reflects the significant risk posed by high levels of fraud and disputes and acts as a deterrent for acquirers who may otherwise overlook or fail to address the problem.

These fees are applied to the acquirer based on the overall fraud and dispute levels within their portfolio, not individual merchants. This means that if an acquirer’s collective portfolio of merchants exceeds the VAMP thresholds, they will be financially liable for these penalties. Acquirers are, therefore, incentivized to ensure that the merchants they manage are actively working to maintain a low level of fraud and disputes, which can be achieved by employing robust fraud detection tools and maintaining strong chargeback management systems.

Merchant Fees

For merchants, the fees for exceeding the VAMP thresholds are also significant, and they can have a lasting financial impact. The fees for merchants under the VAMP program are as follows:

  • $10 per fraudulent or disputed transaction for an Excessive VAMP Ratio: If a merchant exceeds the Excessive VAMP Ratio threshold, which is 1.5% starting in 2025 (and will drop to 0.9% in 2026), they will be charged $10 per fraudulent or disputed transaction. This is a substantial fee that can quickly accumulate, especially for high-volume merchants who process a large number of transactions. To avoid this penalty, merchants must work to maintain a healthy VAMP Ratio by implementing strong fraud prevention strategies and resolving disputes efficiently.

Merchants should be aware that their VAMP Ratio is calculated based on their total number of card-not-present (CNP) transactions, and any fraud or dispute incidents within their transactions can increase their ratio. The Excessive VAMP Ratio reflects a significant failure to manage fraud or disputes, and the associated fees can have a serious financial impact on a business. Consequently, it is essential for merchants to stay within Visa’s defined thresholds to avoid financial penalties and potential disruptions in payment processing.

Three-Month Grace Period: What It Means for First-Time Offenders

Visa recognizes that certain businesses may initially struggle to meet the VAMP program’s requirements, especially if they have recently implemented new fraud prevention strategies or are adjusting to the evolving standards. To accommodate these challenges, Visa offers a three-month grace period for first-time offenders within a 12-month rolling period. During this grace period, merchants and acquirers who exceed the VAMP thresholds for the first time will not face penalties, as long as they bring their fraud and dispute levels back into compliance within the given timeframe.

The grace period provides businesses with an opportunity to correct their performance and avoid long-term consequences. For example, if a merchant’s VAMP Ratio exceeds the threshold in the first quarter of 2025, they will have until the end of the grace period (three months) to reduce their fraud and dispute levels below the threshold. During this time, Visa will not apply fees or penalties, but failure to meet the standards after the grace period will result in the full penalties being applied.

Merchants and acquirers should view the grace period as a valuable opportunity to assess their fraud management practices and improve them if necessary. For businesses that are in industries with higher fraud risks, such as online gaming or nutraceuticals, the grace period can help them transition into full compliance without facing immediate financial consequences.

Risk-Based Enforcement: Visa’s Approach to Fraud and Dispute Management

Visa’s approach to risk-based enforcement in the VAMP program reflects a more tailored and strategic way of managing fraud and disputes. Instead of a one-size-fits-all approach, Visa uses a risk-based model to determine which acquirers and merchants need closer scrutiny or enforcement actions. The risk-based enforcement mechanism allows Visa to focus on businesses that pose a higher risk to the integrity of its payment network, ensuring that resources are allocated efficiently to protect against fraud and disputes.

Merchants and acquirers who consistently exceed the VAMP thresholds are at greater risk of facing more severe enforcement actions. These actions may include fines, additional scrutiny of their business operations, and, in extreme cases, termination from Visa’s network. If a merchant or acquirer fails to address persistent fraud and dispute issues after receiving penalties and corrective notices, Visa may take the step of terminating their ability to process payments through its network, which can have catastrophic consequences for a business’s operations.

Risk-based enforcement also allows Visa to consider factors such as the volume of transactions processed, the history of fraud and disputes, and the proactive measures taken by the business to prevent fraud. For example, a merchant who actively works to reduce fraud and disputes through the use of advanced fraud detection tools and regular communication with their acquirer may be given more leniency if they exceed the threshold for the first time. Conversely, merchants who repeatedly fail to address fraud and disputes in a meaningful way will face more stringent enforcement measures.

Steps for Merchants and Acquirers to Avoid Fees and Penalties

To avoid the hefty fees and potential penalties outlined by the VAMP program, merchants and acquirers need to adopt proactive measures that focus on reducing fraud and disputes. Here are several steps businesses can take to minimize their risk and maintain compliance:

Implement Robust Fraud Prevention Tools

Merchants should invest in real-time fraud detection and fraud prevention tools that can identify suspicious transactions as they occur. Tools like 3D Secure authentication, address verification systems (AVS), and machine learning-based fraud detection can help merchants prevent fraudulent transactions before they are processed. By reducing fraud rates, merchants can maintain a healthier VAMP Ratio and avoid triggering penalties.

Improve Chargeback Management

Having an efficient chargeback management system in place is critical for maintaining low dispute levels. Automated systems that track chargeback reasons, identify trends, and respond quickly to disputes can help merchants resolve issues before they escalate. By addressing disputes proactively, merchants can keep their dispute levels within Visa’s acceptable range and avoid the Excessive VAMP Ratio.

Collaborate with Acquirers

Both merchants and acquirers need to maintain open lines of communication. Acquirers play a key role in monitoring and managing fraud levels within their portfolios, and merchants should ensure they are working closely with their acquirer to implement fraud reduction strategies. Acquirers can help merchants stay compliant by providing guidance on industry best practices and ensuring that merchants are aware of any changes to Visa’s compliance requirements.

Maintaining Compliance and Mitigating Risk

The VAMP program is Visa’s comprehensive effort to manage fraud and disputes across its payment network. While the fees and penalties for non-compliance may seem daunting, they serve as an essential mechanism to ensure the integrity of the global payment ecosystem. By taking proactive steps to manage fraud, disputes, and overall risk, merchants and acquirers can avoid the financial consequences of exceeding the established thresholds.

Understanding the penalties, grace periods, and risk-based enforcement strategies within the VAMP program is critical for businesses that want to continue processing payments through Visa’s network. By implementing strong fraud prevention tools, adopting effective chargeback management practices, and collaborating closely with acquirers, merchants can reduce their risk of facing penalties and ensure a smooth, uninterrupted payment processing experience. In an ever-evolving digital landscape, staying ahead of fraud and disputes is key to thriving in the Visa payment ecosystem.

Understanding the Critical Need for VAMP Compliance

As the Visa Acquirer Monitoring Program (VAMP) continues to reshape how merchants and acquirers manage fraud and disputes, compliance becomes more than just a requirement—it is a critical part of maintaining a healthy and sustainable business. With new thresholds for fraud and disputes, merchants and acquirers must take proactive steps to ensure they stay within the defined limits and avoid penalties. The program’s purpose is not only to reduce fraud but also to enhance the overall security and integrity of Visa’s payment ecosystem. The consequences for failing to meet VAMP standards can include significant fines, penalties, and, in extreme cases, the termination of merchant accounts.

Both merchants and acquirers need to adopt a strategic, risk-aware approach to fraud and dispute management to stay compliant with Visa’s rules. By understanding VAMP’s requirements, implementing best practices in fraud prevention, and proactively monitoring their performance, businesses can mitigate the risks associated with non-compliance. This not only ensures uninterrupted payment processing but also protects a company’s reputation and financial health in the long term. In this section, we will outline actionable strategies for merchants and acquirers to remain compliant with VAMP’s evolving requirements, focusing on fraud prevention, chargeback management, and maintaining optimal performance under Visa’s scrutiny.

Building a Robust Fraud Prevention Strategy

The foundation of staying compliant with VAMP lies in implementing a robust fraud prevention strategy. Fraud is a key contributor to violations of VAMP’s thresholds, and addressing it proactively is critical to minimizing both the risk of penalties and the potential damage to a business’s reputation. Fraud prevention tools and technologies have evolved over the years, and it is essential for merchants and acquirers to leverage these technologies to stay ahead of potential fraudsters.

Real-Time Fraud Detection

One of the most effective strategies for reducing fraud is the implementation of real-time fraud detection systems. These tools use machine learning, artificial intelligence, and data analytics to detect suspicious patterns as transactions occur, allowing merchants to block fraudulent transactions before they are processed. Many modern fraud detection systems also include behavioral biometrics, which tracks user behavior in real time to identify any anomalies that could suggest fraudulent activity.

By catching fraudulent transactions early, merchants can significantly reduce the number of chargebacks, disputes, and fraudulent transactions, all of which contribute to an unfavorable VAMP Ratio. Many fraud detection tools are customizable, allowing businesses to tailor them to their specific needs and industry requirements. For instance, industries like online gaming or nutraceuticals, which are often subject to higher fraud rates, should consider implementing additional layers of fraud detection specific to their risk profiles.

3D Secure and Authentication Tools

Visa strongly encourages the use of 3D Secure (3DS) authentication for card-not-present transactions. 3D Secure adds an extra layer of verification during the payment process by asking consumers to authenticate themselves with a password, one-time PIN, or biometric identification. This reduces the likelihood of unauthorized transactions and, in turn, minimizes the chances of fraud-related chargebacks.

For merchants looking to stay compliant with VAMP, integrating 3D Secure authentication is not just a best practice—it is a critical tool for reducing fraud and improving customer trust. Visa has been rolling out new versions of 3D Secure that incorporate advanced fraud detection mechanisms and a smoother, more seamless experience for consumers. By adopting the latest versions of these tools, merchants can further reduce their exposure to fraud and disputes.

Transaction Monitoring and Reporting

In addition to using real-time fraud detection systems, merchants should actively monitor their transactions to identify patterns that could indicate potential fraud. Transaction monitoring tools help merchants keep track of chargeback trends and fraud alerts, enabling them to adjust their fraud prevention strategies as needed. Regular review of TC40 reports (fraud reports) and other relevant transaction data allows businesses to spot potential fraud early, reducing the chances of it reaching the threshold that would trigger penalties under VAMP.

By identifying patterns such as high-value transactions from new or unverified accounts or excessive international transactions, merchants can flag these activities for further review and take action accordingly. This helps reduce the overall fraud rate and ensures that the merchant’s fraud metrics remain within acceptable limits.

Implementing Effective Chargeback Management Practices

Effective chargeback management is another critical aspect of staying compliant with the VAMP program. Chargebacks—disputes initiated by customers regarding unauthorized or incorrect transactions—can significantly impact a business’s performance under VAMP. A high number of chargebacks not only increases a merchant’s fraud rate but also contributes to the VAMP Ratio, which could push a merchant or acquirer beyond the acceptable limits.

Automated Dispute Resolution Tools

To streamline chargeback management, merchants can utilize automated dispute resolution tools. These systems automatically detect eligible chargebacks and initiate resolution procedures without requiring manual intervention. Automated tools can help merchants resolve disputes quickly and accurately, reducing the chances of chargebacks escalating to excessive levels. Visa’s Pre-Dispute Resolution system allows merchants to automatically handle disputes before they officially become chargebacks, saving both time and money.

Strong Customer Communication and Support

Many chargebacks arise from misunderstandings between customers and merchants, such as issues with product descriptions, shipping delays, or poor customer service. To prevent chargebacks, merchants should maintain clear communication with customers and offer excellent customer support. Customer-friendly policies, such as easy returns and clear shipping timelines, can reduce the likelihood of disputes turning into chargebacks.

Merchants should also ensure that their contact information is easily accessible to customers. If a customer is dissatisfied with a product or service, offering prompt and effective solutions can prevent them from filing a dispute with their card issuer.

Clear and Accurate Billing Descriptors

One often-overlooked element of chargeback prevention is the billing descriptor—the text that appears on a customer’s bank or credit card statement. If a customer fails to recognize a charge from a merchant, they are more likely to dispute the transaction. To minimize the chances of accidental chargebacks, merchants should ensure that their business name, product descriptions, and contact details appear clearly and accurately on the customer’s billing statement. Customizing billing descriptors using solutions like Dynamic Soft Descriptors can help customers identify transactions correctly and reduce the risk of chargebacks.

Maintaining Active Communication with Acquirers

For both merchants and acquirers, effective communication is key to staying compliant with VAMP and managing risk. Acquirers act as intermediaries between merchants and Visa, and they play a crucial role in monitoring the fraud and dispute metrics of their merchant portfolios. It is essential for merchants to work closely with their acquirer to ensure that they are on track to meet VAMP requirements.

Acquirers should provide merchants with insights and feedback on their fraud and dispute levels, helping them identify potential risks before they escalate. In turn, merchants should inform acquirers about any challenges they may be facing in terms of fraud management, chargeback reduction, or overall compliance. This collaborative approach can help both parties address issues early and stay within Visa’s compliance thresholds.

Regular Performance Monitoring and Reporting

Both merchants and acquirers should regularly review their performance data to stay on top of fraud and dispute levels. Merchants should monitor their VAMP Ratio regularly to ensure they are not approaching the thresholds for fraud or disputes. Regular monitoring of TC40 (fraud) and TC15 (disputes) reports, as well as tracking key performance indicators (KPIs) related to fraud and chargebacks, is essential for ensuring compliance.

Acquirers can assist in this process by providing regular reporting and performance reviews for their merchant portfolios. This proactive approach allows both parties to identify emerging risks and make adjustments to their fraud prevention and chargeback management strategies as necessary.

Staying Informed: Adapting to Changes in VAMP

Visa’s VAMP program is evolving, and staying informed about changes to the thresholds, enforcement rules, and compliance expectations is crucial for long-term success. Merchants and acquirers must remain agile and adapt their strategies as Visa updates the program in response to emerging trends in fraud and payment security. Keeping abreast of any updates from Visa and participating in training sessions, webinars, or industry forums will ensure that merchants and acquirers are well-equipped to comply with the latest VAMP requirements.

Conclusion
