In the first part of our guide, we explained how category codes, or MCC, define your risk level in the eyes of the banks. Now it is time to dig into every high risk merchant's biggest fear, the strict monitoring programs run by Visa and Mastercard. Many business owners mistakenly believe that receiving a chargeback simply means losing the money from a single sale. The operational reality is far more severe.
What a chargeback really means for your business
Card brands do not tolerate high dispute levels, because this erodes consumer trust in the global financial system. To protect their reputation, they built relentless monitoring algorithms that track your return rate month after month, merchant by merchant.
Every chargeback you receive is not just a lost sale. It is a data point added to a ratio, and that ratio decides whether your processing account stays alive or ends up in intensive care.
The strict thresholds set by Visa and Mastercard
These corporations work with mathematical limits that are practically unbreakable. Crossing them, even by a small margin, triggers automatic consequences that no acquiring bank can ignore.
Visa's new standard, the Visa Acquirer Monitoring Program (VAMP)
As of April 1, 2025, Visa consolidated its former fraud and dispute programs, including the well known Visa Dispute Monitoring Program, into a single program called the Visa Acquirer Monitoring Program (VAMP). Under this new framework, Visa monitors both the acquiring bank and the individual merchant, setting a threshold of 0.50% for the "Above Standard" tier and 0.70% for the "Excessive" tier, calculated on combined fraud and dispute volume. It sounds like a narrow margin, but for high volume businesses it only takes a handful of poorly managed disputes to cross that line.
Mastercard's critical limit, 1%
Mastercard sets its tolerance threshold at exactly 1%. Just like Visa, this figure is calculated on monthly cycles, so a single spike in fraud or dissatisfied customer claims can push you past the limit without warning.
If your chargeback metrics are already close to the limit, every week counts. Start processing payments for your high risk company now with a partner who understands these rules.

Being enrolled in these programs is not a friendly warning sitting in your inbox. It marks the start of a countdown against your cash flow.
Visa Acquirer Monitoring Program (VAMP)
If you exceed Visa's threshold, your business is enrolled in the Visa Acquirer Monitoring Program, the program that replaced the former Visa Dispute Monitoring Program. From that point on, your acquiring bank must report your metrics periodically and justify a dispute reduction plan directly to Visa.
Mastercard's Excessive Chargeback Program (ECP)
Mastercard applies the same principle through its Excessive Chargeback Program. The difference is that its penalty scale tends to accelerate faster if the merchant fails to show clear improvement within the first two or three cycles.
Fines that escalate from a few hundred to tens of thousands of euros
Card brands impose direct financial fines that escalate aggressively month after month. At first the penalties may hover around a few hundred euros, something many merchants overlook or pay without a second thought. That is the most expensive mistake in this industry.
If you fail to bring your fraud metrics down quickly, penalties can reach tens of thousands of euros per month. And those fines are not absorbed by the card brand, they are absorbed by your acquiring bank, which in turn passes them on to you, often alongside an immediate increase in your rolling reserve.
Every month spent inside a monitoring program without a clear plan is money lost. Start processing payments for your high risk company now and regain control of your metrics.
Start my assessment You pay nothing unless approvedPermanent account closure, the worst case scenario
Eventually, European acquiring banks are forced by Visa and Mastercard's own rules to permanently close the merchant account. No bank will risk its core license to protect a merchant that cannot control its disputes.
Worse still, a closure caused by excessive chargebacks can result in your business being added to the MATCH list, making it extremely difficult to secure a new processing account with any European bank for years.

What is the difference between a chargeback and a refund
A refund is initiated voluntarily by the merchant, while a chargeback is initiated by the card issuing bank at the customer's request, without the merchant being able to intervene at the initial stage. On top of that, a chargeback usually comes with an additional fee that a refund does not generate.
How long does a merchant stay inside a monitoring program
It depends on the brand and how quickly the merchant brings its dispute ratio back below the threshold. In practice, it usually takes between three and six consecutive months of healthy metrics before officially exiting the program.
Can a merchant get off the MATCH list
Yes, although it is a long and complex process that typically takes between five and eight years, or requires a specialized advisor to negotiate directly with the bank that reported the listing.
