What to Do When Your Processor Sends a Warning

TL;DR
  • A warning email doesn't mean your account is closed. It means you're approaching or have crossed a threshold.
  • Your first action is to find out exactly which threshold you crossed (chargeback ratio, fraud ratio, or both) and by how much.
  • On VAMP, grace covers program months 1, 2 and 3. Fees start in program month 4. Count from the identification notice, not from the month you breached. Use the window to cut disputes hard.
  • The playbook: identify root cause, fix the biggest leak first, document everything for your processor.

You opened an email from your processor and your stomach dropped. Words like "monitoring program," "excessive chargebacks," "remediation required," or "account review" stare back at you.

Take a breath. This email is the warning shot, not the outcome, and most merchants who get one never see a fine.

Types of Processor Warnings​

Not all warning emails are equal. Here's what each type means:

Warning TypeSeverityWhat It MeansTime to Act
Friendly heads-upLowYour ratio is trending up but not yet at thresholdWeeks to months
Early warning notificationMediumYou've hit an early warning threshold (~0.65%)1-2 months before escalation
Monitoring program entryHighYou've crossed a processor or network threshold (~0.9% at most processors; MC ECM needs 100-299 disputes and 1.50-2.99%)Fines start in 1-4 months
Remediation requiredHighYou must submit a plan to reduce disputesDays to weeks
Account review / potential terminationCriticalYour account may be closedImmediate

Step 1: Find the Numbers​

Before you do anything else, find out exactly where you stand. Log into your processor dashboard or call your account manager and get these numbers:

What to FindWhy
Your current chargeback ratioVisa VAMP treats a merchant as excessive at 1.5% (2.2% in CEMEA). Mastercard ECM starts at 1.50%. Your processor's house limit sits lower than both, often around 0.9%
Your current dispute countEvery one of these programs needs a count as well as a ratio. VAMP has a floor of 1,500 combined fraud reports and disputes in the month; ECM needs 100 to 299 chargebacks, and 300 or more moves you to HECM. Under the count, the ratio alone can't put you in the program
Which months triggered the warningIs this a one-month spike or a trend?
Which network program you're inVAMP? Mastercard ECM? Both? Or just your processor's internal watchlist, which isn't a network program and carries no network fine
Your current month in the programThe month number decides whether you owe money yet. See the timeline in Step 2

When you recalculate the ratio yourself, watch the denominator, because the two networks don't use the same one. Mastercard divides this month's chargebacks by last month's transaction count. Visa uses the same calendar month for both. If your volume is growing fast, your Mastercard ratio will read higher than your Visa ratio on identical data, and that gap is arithmetic rather than a new problem.

Ask your acquirer for the numbers in your agreement

Neither Visa nor Mastercard publishes its monitoring thresholds, fine schedules or exit criteria. Every figure on this page reached the public through acquirers passing on notices, and acquirers apply stricter house limits on top. The only thresholds that can actually cost you money are the ones your own acquirer is measuring you against, so ask them in writing.

See Network Programs Reference for the full threshold tables and fee schedules.

Step 2: Understand the Timeline​

You have more time than the email makes it feel like.

Visa VAMP:

MonthWhat Happens
1-3Grace period on first identification. No fees yet. This is your window to fix things.
4+Per-dispute fees begin: USD 8 per CNP dispute once you're at merchant excessive. The USD 4 rate is an acquirer-portfolio charge, not a merchant tier, so whether any of it reaches you depends on your acquirer's own status. At high dispute volumes this adds up fast.
PersistentTermination risk.

Two things about those VAMP figures. Visa bills them to your acquirer, not to you, and your acquirer decides how much to pass through, so ask yours what they charge. And the $4/$8 numbers come from Checkout.com's merchant notice of 12 June 2026, not from Visa. Visa's own VAMP fact sheet carries no fee figures at all, so treat any page that cites Visa for these numbers with suspicion.

Mastercard ECM:

MonthWhat Happens
1Warning. No fines yet.
2-3$1,000/month.
4-6$5,000/month.
7-11$25,000/month.
12+$50,000-$100,000/month and escalating.

Remember that ECM needs 100-299 disputes and a 1.50-2.99% ratio in the same month. Clear either one and you're out of the program. Above 300 disputes and 3.00% you're in HECM instead, where the schedule escalates faster.

To exit: get below the count threshold, the ratio threshold, or both, and hold it. Acquirers commonly ask for three consecutive clean months before they stop treating you as a monitored merchant, but the exit rule is unpublished and yours may differ. Ask your acquirer to put its exit criteria in writing at the same time you ask for your monthly numbers.

Step 3: Find the Root Cause​

Pull your last 30 chargebacks. Categorize each one:

CategoryWhat It Looks LikeLikely Fix
"I don't recognize this"Reason code 10.4, no customer contact firstFix your billing descriptor (Descriptors)
"I cancelled"Reason code 13.2, subscription disputesMake cancellation easier (Refund Policy)
"Never received"Reason code 13.1Add tracking and delivery confirmation
Actual fraudReason code 10.4, different name/addressEnable 3DS (3D Secure)
Friendly fraudReason code 10.4, but customer used the productCollect device/IP evidence for CE 3.0 (Compelling Evidence)

If one category makes up more than 40% of your chargebacks, fix that one thing first.

Step 4: Take Immediate Action​

This week:

  • Sign up for chargeback alerts (Ethoca, Verifi CDRN, or RDR). These let you resolve disputes before they become chargebacks.
  • Refund any pending customer complaints that could become disputes. A refund costs 3%; a chargeback costs $50+.
  • Check your billing descriptor. If it doesn't clearly show your business name, fix it today.

This month:

  • Enable 3D Secure if you haven't already. It shifts fraud liability to the issuer.
  • Make cancellation self-service (no phone-only cancellation).
  • Reduce refund processing time to same-day or next-day.

Ongoing:

  • Track your chargeback ratio weekly, not monthly. You need to see the trend moving down.
  • Follow the Reduce Chargebacks Fast playbook for the full crisis response.

Step 5: Talk to Your Processor​

Your processor isn't your enemy here. They don't want to terminate you (they make money from your transactions). But they need to see that you're taking action.

What to tell them:

  1. You're aware of the issue
  2. You've identified the root cause (be specific: "42% of our disputes are descriptor confusion")
  3. Here's what you've already done (alerts signed up, descriptor fixed, 3DS enabled)
  4. Here's your plan for the next 30/60/90 days
  5. Ask: "What specifically do you need from me to stay in good standing?"

What to ask them:

  • Can they share your exact ratio by month for the last 6 months?
  • Are they reporting both Visa and Mastercard ratios, or just one?
  • Do they have any additional tools or programs that could help (some processors offer fraud tools or alert programs)?
  • What's their termination threshold, and how close are you?

Communication Templates​

Phone Script: First Call After Warning​

Use this when calling your processor's risk team:

"Hi, I'm [your name] with [business name], merchant ID [your MID]. I received an email about [chargeback monitoring / account review / excessive disputes]. I want to understand exactly where I stand and share what I'm doing about it.

Can you tell me:

  1. My exact chargeback ratio for the last 3 months?
  2. Which network program I've been placed in, and what month I'm in?
  3. What specific metrics I need to hit, and by when, to exit the program?

Here's what I've already done: [list 2-3 actions, e.g. alerts signed up, descriptor fixed, refund policy updated]. I'm putting together a full remediation plan. What format do you need that in, and who should I send it to?"

Email Template: Remediation Plan​

Send this within 48 hours of the warning:

Subject: Remediation Plan - [Business Name] - [MID]

[Processor Risk Team],

Thank you for notifying us about our chargeback ratio. We take this seriously and have already begun remediation.

Current situation: Our ratio reached [X%] in [month], driven primarily by [root cause, e.g. "descriptor confusion" or "subscription cancellation disputes"].

Actions already taken (this week):

  • Enrolled in [Verifi RDR / Ethoca alerts / CDRN] for pre-dispute resolution
  • Updated billing descriptor from "[old]" to "[new]"
  • Authorized support team to issue same-day refunds for billing inquiries

30-day plan:

  • [Specific action 1, e.g., "Enable 3DS on all transactions over $50"]
  • [Specific action 2, e.g., "Add cancellation self-service to customer portal"]
  • [Specific action 3, e.g., "Send renewal reminder emails 7 days before charge"]

Target: Reduce ratio to below [X%] within [60/90] days.

We will send weekly updates on our progress. Please let us know if you need anything additional.

Best regards, [Your name]

Email Template: Weekly Progress Update​

Why Written Updates Matter

Processors handle thousands of merchants. A weekly email creates a paper trail showing you're actively fixing the problem. If your account ever goes to a termination review, this documentation can save you.

What If Your Account Gets Terminated​

If your processor terminates your account:

  1. Don't panic about MATCH. Not all terminations result in MATCH listing. Ask your processor directly: "Will I be placed on MATCH?" If the answer is yes, see MATCH/TMF.
  2. Find a new processor immediately. Some processors specialize in higher-risk merchants. You'll pay higher fees, but you can keep processing.
  3. Fix the underlying problem first. A new processor won't help if you bring the same chargeback problem with you.

Scale Callout​

VolumeFocus
Under $100K/monthAlert services may cost more than they save at low volume. Focus on descriptor fixes and refund policy instead.
$100K-$500K/monthAlert services are cost-effective. Enable 3DS. Consider a chargeback management vendor.
Over $500K/monthFull alert coverage (Ethoca + Verifi + RDR). Dedicated dispute management. Weekly ratio monitoring.
