For high-risk merchants, staying compliant with Visa’s rules is no longer just about keeping chargebacks low. The new Visa Acquirer Monitoring Program (VAMP) guidelines give acquirers tighter control, with stricter thresholds and tougher enforcement measures. If you slip up, termination isn’t just possible, it’s likely.
What makes this different from earlier monitoring programmes is the level of detail Visa now requires. Acquirers are expected to track chargeback ratios, fraud patterns, refund behaviour, and even how clearly you present your billing descriptors. If the data shows consistent risk or poor practices, your acquiring bank has little choice but to shut you down before Visa intervenes.
For merchants in industries like subscriptions, gaming, nutraceuticals, or adult services, this raises the stakes. Operating without a clear plan for VAMP compliance means gambling with your payment processing lifeline.
In this article, we’ll walk through five proven strategies to avoid termination under these new rules.
What is The VAMP Update?
Visa’s 2025 update to the Visa Acquirer Monitoring Program (VAMP) replaces separate fraud and chargeback tracking with a single VAMP ratio. This ratio combines disputes and fraud against total card-not-present sales. New rules also add enumeration monitoring for card-testing attacks. The advisory period runs until September 2025, with enforcement starting October and thresholds tightening to 0.9% globally by January 2026.
Five Ways to Avoid Termination Under VAMP
Keep Chargebacks Under Control
Chargebacks are the single biggest red flag under Visa’s VAMP guidelines. Visa flags merchants if chargebacks exceed 0.9% of sales volume OR 100 chargebacks in a single month. High-risk verticals often get less tolerance.
Action steps:
- Monitor ratios weekly, not monthly.
- Use Ethoca/Verifi alerts to intercept disputes before they count.
- Keep refund policies visible as Visa considers hidden refund processes a driver of chargebacks.
- Store evidence for representation (delivery proof, customer comms).
Staying below Visa’s thresholds is about prevention and fast response. The less friction you create for customers, the less likely they are to dispute transactions, and the safer your merchant account becomes.
Be Transparent in Marketing and Billing
One of the quickest ways to trigger VAMP violations is through unclear or misleading practices. Visa requires acquirers to keep a close eye on how merchants present their products, pricing, and billing information. For high-risk businesses, even small inconsistencies can look like intentional deception.
Action steps:
- Use your trading name in descriptors and avoid generic codes like “ONLINE PAY.”
- Show full pricing and renewal terms at checkout. Trial conversions with unclear pricing are a major trigger.
- Align website, receipts, and terms. Acquirers now audit for mismatches.
Visa specifically reviews billing descriptors and complaints tied to “unrecognised charges.” By eliminating surprises for customers, you reduce complaints, lower disputes, and demonstrate to acquirers that you operate with integrity.
Implement Strong Fraud Prevention Systems
Fraud is another critical metric Visa monitors under VAMP. For high-risk merchants, where stolen cards and friendly fraud are common, building strong fraud prevention into daily operations is essential.
Visa requires acquirers to monitor fraud under the Visa Fraud Monitoring Program (VFMP). Merchants are flagged if fraud exceeds 0.9% of sales AND $75,000 in fraud volume per month.
Action steps:
- Enable 3-D Secure 2.0 and AVS checks on all high-risk transactions.
- Set velocity filters (limit multiple transactions per card/device).
- Use device fingerprinting to block repeat fraud attempts.
- Track decline patterns; sudden spikes usually mean fraud testing.
Merchants who invest in robust fraud systems are far less likely to fall into VAMP’s danger zone.
Work Closely With Your Acquirer and Payment Processor
Under VAMP, acquirers are the first line of enforcement. If your account looks risky, Visa expects your acquiring bank to step in quickly. That makes your relationship with them more important than ever.
Action steps:
- Schedule monthly compliance reviews.
- Share your internal chargeback/fraud reports proactively.
- Notify your acquirer before launching new products, geographies, or billing models. “Hidden activity” is a common reason for termination.
The merchants who survive under VAMP are those who keep their acquirers informed and engaged. If your bank knows you’re proactive, they’re more likely to defend your account when Visa reviews it.
Maintain Accurate and Updated Documentation
VAMP isn’t just about numbers. Acquirers are also responsible for checking whether your business records are accurate and up to date. Missing or outdated documentation can raise red flags, especially for high-risk merchants where the margin for error is small. Being audit-ready at all times shows that you take compliance seriously.
Action steps:
- Keep incorporation docs, licences, and AML/KYC policies updated.
- Track refund ratios; Visa considers >15% refunds a risk trigger.
- Maintain a central compliance folder that can be provided within 24 hours of an acquirer request.
Good documentation not only protects you in an acquirer review but also demonstrates to Visa that your business is operating transparently and responsibly.

Conclusion
Visa’s revamped VAMP raises the bar for high-risk merchants. The separate chargeback and fraud thresholds are gone, replaced by a single metric that covers disputes, fraud, and enumeration. Starting at 1.5% in 2025 and tightening to 0.9% in 2026, the margin for error is shrinking quickly.
High-risk merchants must:
- Monitor fraud, disputes, and enumeration metrics in real time.
- Keep ratios well below thresholds by using prevention and dispute management tools while ensuring TC40 and TC15 cases are avoided.
- Work closely with acquirers during the advisory period to build trust and demonstrate responsiveness before enforcement begins.
Survival under VAMP requires being proactive, transparent, and responsive. Adapt now, because once enforcement starts, mistakes leave very little room for recovery.
FAQs
1. What is Visa’s VAMP program?
The Visa Acquirer Monitoring Program (VAMP) requires banks to track merchants for excessive chargebacks, fraud, and deceptive practices. Acquirers must report non-compliance to Visa and face fines if they don’t act.
2. What are the chargeback thresholds under VAMP?
Merchants are flagged if they exceed 0.9% of sales or 100 chargebacks in a month. Crossing 1.8% categorises you as an Excessive Chargeback Merchant, which usually leads to termination.
3. How does Visa monitor fraud under VAMP?
Visa uses the Visa Fraud Monitoring Program (VFMP). You’re flagged if fraud exceeds 0.9% of sales AND $75,000 in value per month. Acquirers also look at refund rates and repeat dispute patterns.
4. Can my account be terminated even if I fix the issues later?
Yes. If you breach thresholds repeatedly or fail to respond quickly, your acquirer may close the account to avoid fines. Proactive monitoring and early corrective action are key.
5. What industries are most at risk under VAMP?
High-risk sectors such as nutraceuticals, gaming, adult services, travel, and subscription businesses face tighter scrutiny. These industries often deal with higher dispute rates and are monitored more aggressively.
