What UK Merchants Must Do Now
Since April 2025, UK merchants have been operating under Visa’s Acquirer Monitoring Program (VAMP) — a unified compliance framework that brings fraud and chargeback monitoring into one system.
For years, Visa managed fraud and chargeback thresholds separately. Merchants could keep their ratios under control by using Rapid Dispute Resolution (RDR) or by segmenting issues into different categories. Under VAMP, that separation no longer exists. All disputes — fraud and non-fraud — now count against a merchant’s compliance status.
For businesses in subscription models, e-commerce, hospitality, and other high-risk sectors, the change is significant. It demands stronger fraud prevention, clearer billing practices, and faster dispute management than ever before.
This guide explains what Visa VAMP means in practice, who is most at risk, and how businesses can protect themselves.
What Visa VAMP Requires
Unified Fraud and Chargeback Monitoring
Previously, Visa tracked fraud disputes and non-fraud chargebacks in separate programmes. VAMP merges them. Every dispute — whether a stolen card, a refund disagreement, or a billing descriptor complaint — now feeds into the same compliance calculation.
Rapid Dispute Resolution (RDR) Changes
RDR was once a useful tool. Merchants could resolve disputes automatically without them hitting official ratios. Under VAMP, those days are over. RDR cases now count against your dispute ratios, making it harder to mask underlying problems.
Stricter Thresholds
Visa has tightened the thresholds merchants must stay under. While Visa doesn’t publicly publish every vertical’s limits, acquirers report that for many categories the tolerance is now 1–2% of transactions in dispute. Go over, and you risk fines, higher processing fees, or closer monitoring.
Consequences for Non-Compliance
Merchants who exceed VAMP thresholds face:
-
Increased scrutiny from acquirers
-
Higher processing costs
-
Penalties or fines from card schemes
-
In extreme cases, restrictions on card acceptance
For UK businesses, already contending with fraud losses of £1.2 billion in 2024 (UK Finance), failing to control disputes is not an option.
Who Is Most at Risk?
While all merchants need to adapt to VAMP, some industries face greater challenges:
-
Subscription Services — Recurring billing often leads to disputes when customers forget sign-ups or renewal terms are unclear.
-
Digital Goods Providers — Gaming, streaming, and e-commerce platforms with intangible products are more likely to face “product not as described” disputes.
-
High-Risk Verticals — Travel, hospitality, and luxury goods often involve high-ticket purchases, cross-border payments, and volatile dispute rates.
-
Hospitality (MCC 5812) — Restaurants and bars that still rely on tip adjustments after authorisation risk being flagged directly under Visa VAMP.
Common Merchant Pitfalls Under VAMP
-
Unclear Billing Descriptors
Customers who don’t recognise your brand on their statement are more likely to raise disputes. -
Delayed Refunds
Long refund processes push frustrated customers straight to their card issuer. -
Manual Tip Adjustments
In hospitality, mismatched authorisation and settlement amounts are a red flag under MCC 5812. -
Relying on RDR
Merchants who used RDR to mask disputes now see those cases counted against them. -
Weak Fraud Prevention
Without tokenisation, SCA, or 3D Secure in place, merchants remain exposed to fraud and chargebacks.
How to Stay Compliant with Visa VAMP
1. Improve Billing Transparency
-
Use clear, consistent statement descriptors.
-
Send confirmation emails/SMS with the descriptor shown so customers know what to expect.
2. Enhance Customer Communication
-
Proactive reminders for renewals and subscriptions.
-
Clear cancellation and refund policies that customers can access easily.
3. Strengthen Fraud Prevention
-
Deploy 3D Secure 2.0 to authenticate customers.
-
Use tokenisation to protect cardholder data.
-
Monitor for unusual transaction patterns with fraud detection tools.
4. Optimise Dispute Handling
-
Train staff to resolve issues quickly before they escalate.
-
Use analytics to track dispute trends and address root causes.
5. Work With the Right Payment Partner
Platforms like SOTpay help merchants simplify compliance by:
-
Keeping sensitive data out of your systems (shrinking PCI DSS scope).
-
Supporting Strong Customer Authentication across channels.
-
Offering secure pay-by-link transactions to reduce fraud exposure.
-
Shifting liability to issuers when 3D Secure is used.
The Bigger Picture: Why VAMP Matters
Visa’s decision to launch VAMP reflects a broader shift in the payments industry. Fraud and disputes are rising globally, with Juniper Research projecting $343 billion in e-commerce fraud losses worldwide between 2023 and 2027.
Card schemes and acquirers are under pressure from regulators and consumers alike to clean up dispute volumes. For merchants, that means tighter controls — and fewer loopholes.
Handled well, though, compliance with VAMP isn’t just about avoiding penalties. It can become a competitive advantage. Businesses that can demonstrate low dispute ratios and strong fraud controls may unlock better acquiring rates, lower fees, and stronger banking relationships.
