What happens after approval
Approval is the beginning of a monitored relationship. Here is how acquirer monitoring actually works, and what changes the outcome when your ratio moves.
Approval is the beginning of a monitored relationship
The acquirer that underwrote you keeps reporting on you every month, to itself and to the card schemes, and it can close the account you worked to open after two bad months.
Most merchants only learn how monitoring works once they are already in it. By then, the options have narrowed, and the cost of each one has gone up.
How is the ratio calculated?
The number that decides your standing is a ratio, and merchants regularly measure a different one than their acquirer does.
Visa has historically measured monthly disputes against sales transactions in the same month. Mastercard’s excessive chargeback program measures chargebacks in a month against transactions in the preceding month. The difference sounds academic until volume moves. A merchant coming out of a seasonal peak carries December’s disputes against January’s smaller transaction count, and the ratio jumps without a single additional chargeback. Confirm the exact formula your acquirer reports on, because the two produce visibly different numbers on the same book.
Visa consolidated its monitoring into VAMP, shifting the emphasis to the acquirer’s portfolio ratio and bringing fraud reports and disputes together into a single measure. The practical effect for merchants is that acquirers are now more sensitive to accounts running anywhere near a threshold, because your ratio contributes to theirs. Thresholds have been revised more than once since their introduction, so take the current figures from your acquirer rather than from an article.
Mastercard runs its own excessive chargeback and excessive fraud programs, with penalties that escalate each month a merchant stays in them, plus remediation requirements.
Refunds do not repair the ratio. A refund issued after the chargeback has been filed still counts as a chargeback. An excessive refund rate also draws attention on its own, because it suggests either a fulfillment problem or something worse.
Disputes are not the only problem
Treating chargebacks as a single number to be reduced leads to spending money in the wrong place. Reason codes group into four situations, each with different fixes.
Genuine third party fraud responds to authentication and to fraud rules. 3DS2 with sensible exemption handling shifts liability to the issuer on authenticated transactions, and network tokens reduce credential theft exposure. Authentication changes who bears the loss, not whether a dispute occurs, which matters because a liability shifted dispute can still count against your ratio, depending on the program.
Disputes where the cardholder does not recognize the transaction are a communication problem. The billing descriptor is the first fix, and it should reflect the brand the customer actually bought from, not the legal entity name nobody recognizes. Order confirmations, a visible customer service route, and a clear transaction date do the rest.
Subscription and recurring disputes come from the cancellation experience and from what was disclosed at signup. If canceling requires an email and two working days while signing up took one click, you are funding your own chargebacks. The card scheme rules on recurring disclosure and cancellation exist precisely because this pattern is so reliable.
Service or goods disputes come from fulfillment. Delivery evidence, tracking tied to the cardholder’s address, realistic delivery windows, and honest stock availability resolve most issues at the source.
Fighting what you can win
Representment costs staff time, and you pay the fee regardless of the outcome. Fighting everything wastes both. Fighting nothing teaches your dispute rate that nothing happens.
Decide on evidence. If you hold delivery confirmation, authentication data, or a record of the customer using the service after the disputed date, you have a case worth making. If the customer genuinely did not receive what they paid for, refund them and fix the cause.
Visa’s compelling evidence rules for fraud disputes allow a merchant to use prior undisputed transactions with the same cardholder to challenge a fraud claim, which is effective for subscription and repeat purchase businesses that retain the supporting data. Build the evidence collection into the transaction flow rather than reconstructing it under a deadline.
Prevention before the chargeback exists
A layer of tools sits between the cardholder’s complaint and the chargeback itself. Issuer facing services push merchant and transaction details into the cardholder’s banking app so that a transaction is recognized before it is disputed. Alert networks notify you of a fraud report or a pending dispute in time to issue a refund. Automated resolution services refund qualifying disputes on your behalf according to rules you set.
These work and cost money per event, so set the rules deliberately rather than refunding everything below a threshold. Also, be aware that the way each resolution type counts toward the monitoring programs has changed, and a deflected dispute does not always disappear from all measures. Ask your acquirer specifically how alerts and automated refunds are treated in the ratio it reports on you.
What does the acquirer do when the ratio moves
Rarely is termination the first step. Usually a sequence.
A review, then a request for an explanation and a remediation plan. Then a reserve increase or a longer settlement hold, because the acquirer is repricing the same liability it underwrote at the start. Then a volume cap or a price change. Termination comes last, and it results in a MATCH listing that follows the business and its owners for 5 years.
The merchants who come through this well arrive with their own analysis first. A file that shows the cause, the fix, the implementation date, and the trend since then turns a risk conversation into a commercial one. A merchant who waits to be asked is, by definition, negotiating from the weaker position.
What to watch monthly
Your dispute ratio, calculated the way your acquirer calculates it, not the way your reporting defaults to. Your fraud ratio in basis points of volume, which moves before disputes do and gives you a warning. Approval rate by issuing country, because a drop there costs more revenue than disputes do. Refund rate. And the split of disputes by product, traffic source, and acquiring region, since the cause is almost always concentrated rather than spread out.
Aggregate numbers hide the problem. A stable overall ratio can include one product line or one affiliate source that is deteriorating fast enough to end the account.
The commercial case
Chargeback work gets underfunded because its costs sit across several budgets at once. Lost goods, transaction fees, chargeback fees, shipping, staff hours, and then the fees and the reserve when a threshold is breached. None of that captures the highest cost: losing the acquiring relationship and rebuilding it from a MATCH listing.
Present it as one figure to the board, and the investment decision becomes straightforward.
How does PPS work on this
We analyze disputes by cause rather than by volume, fix the ones driven by descriptors, cancellation flows, and fulfillment, and build the evidence and prevention layer around what remains. When an account is already under review, we prepare the remediation file the acquirer needs and communicate with them directly.
You work directly with the senior team, and we stay in the room until the ratio moves.
