The Cost of Non-Compliance: Fines and Fees Under Visa and Mastercard

‍

Visa and Mastercard each operate their own monitoring programs to track excessive fraud and chargebacks. If you're a merchant with a rising dispute ratio or an acquirer managing a risky portfolio, those thresholds can lead to real costs if they’re crossed. 

Visa’s newly consolidated Acquirer Monitoring Program (VAMP) brings together dispute and fraud oversight into a single framework. As of April 2025, the standard merchant threshold for excessive activity is a VAMP ratio of 1.5%. By January 2026, that figure will drop to just 0.9%. Acquirers, meanwhile, can be flagged at a ratio as low as 0.3% depending on geography. And with Visa removing its early warning tier, the margin for error is now razor-thin.

Meanwhile, Mastercard’s Excessive Chargeback Program has a slightly different structure but no less weight. Merchants are flagged as ECM when they exceed 100 chargebacks in a month with a chargeback rate above 1.5%. Hit 300 chargebacks and cross the 3.0% threshold, and you’ll be placed in the HECM tier — a far more serious designation. These aren’t soft warnings. Once you're in, you’re paying the price.

What the Fines Actually Look Like

The most immediate consequence of exceeding these thresholds is monetary. And it adds up fast.

Under Visa’s VAMP program, merchants and acquirers classified as “Excessive” pay a $10 fine for every dispute or fraud transaction over the line. It’s a straightforward penalty that’s easy to underestimate. One hundred chargebacks? That’s $1,000. One thousand? That’s $10,000 in a single month. Acquirers take the hit, but most will pass the cost downstream to the merchant.

Mastercard escalates the cost more aggressively. An HECM merchant that remains non-compliant for several months can expect to pay $25,000 to $100,000 in monthly fines, depending on how long they remain over the threshold. Add to that Mastercard’s issuer recovery fees — around $5 per chargeback beyond 300 — and the admin burden of detailed reporting requirements, and it’s clear these programs are designed to apply pressure, not just punish.

And that's just the network-level impact. Most acquirers also impose their own internal penalties, like increased processing fees, rolling reserves, or even accelerated termination if a merchant can't course-correct. In that context, the card network fine is just the beginning.

Risk Flows Downstream

One of the more underappreciated consequences of these programs is how they shift responsibility. Acquirers don’t just bear their own risk; they’re accountable for their entire merchant portfolio. If too many merchants exceed Visa’s VAMP threshold, the acquirer can be placed in the program even if no single merchant seems excessive on their own.

That dynamic has changed how acquirers manage risk. Today, many enforce limits well below the card network thresholds. A merchant with a 0.8% chargeback ratio may find themselves flagged long before they hit Visa’s 0.9% mark. Some acquirers now issue formal remediation plans or even pre-emptive warnings based on internal tolerances. Others simply refuse to board merchants in high-risk verticals unless strict mitigation measures are in place from day one.

It’s not about being cautious but rather about surviving. If a merchant doesn’t bring their ratios down, the acquirer risks being fined for every transaction that the merchant processes. That’s not a cost many are willing to absorb.

Non-Compliance Means Getting Frozen Out

Fines are painful, but in many cases, the reputational fallout is worse. Once a merchant is placed into a monitoring program, that status becomes known throughout the acquiring ecosystem. Processors talk. Risk profiles travel. If you’re seen as a liability, getting a new account or renegotiating an existing one gets exponentially harder.

Worse still is the possibility of account termination. If a merchant remains in non-compliance for several months, many acquirers will simply shut down the account to stop the bleeding. At that point, Mastercard may place the merchant on the MATCH list, an industry-wide database of terminated merchants shared across all acquiring banks. If you end up on MATCH, finding a new provider is difficult, expensive, and in some cases, impossible.

There’s no silver lining to being in that position. The best way to survive is to never get there in the first place.

Prioritizing Prevention Over Reaction

All of this underscores one simple truth: by the time you’re dealing with fines, you’re already behind. The smarter approach is prevention via systems, tools, and protocols designed to keep you under threshold in the first place.

Visa and Mastercard make no secret of what they value: Proactive dispute resolution, strong fraud controls, and a clear reduction in customer complaints. Programs like Verifi’s Rapid Dispute Resolution (RDR) and Ethoca Alerts are explicitly designed to stop chargebacks before they reach the network. 

In fact, Visa now excludes RDR-resolved disputes from its VAMP ratio entirely. It’s a clear incentive to intercept disputes early, and merchants who don’t take advantage of it are leaving themselves exposed. Likewise, implementing real-time fraud filters, improving refund policies, and tightening up fulfilment processes all contribute to a lower dispute ratio. 

Ultimately, the days of letting chargebacks “sort themselves out” are over. If 2025 has proven anything, it’s that Visa and Mastercard are raising the bar, and those who fall behind will pay the price. The most successful merchants and acquirers don’t just react to dispute spikes. They build infrastructure to prevent them.

That might mean adopting early resolution tools. It might mean investing in better customer communication or revisiting how billing descriptors appear on statements. It might mean partnering with a dedicated chargeback prevention provider that can monitor, alert, and respond before you ever hit the danger zone. Because once you’re in a program, the cost of getting out is high
