Payment scheme fees rarely arrive with a warning, instead appearing as a line item weeks or even months after the bulletin that announced them. By then, the operational window to intervene has long closed. The decision that triggered the charge happened in a previous quarter. And your next billing cycle is already accumulating the same exposure.
This is the structural issue with scheme compliance: the financial consequences of oversights are almost always visible after the fact.
The gap between action and consequence
Payment networks use a range of monitoring programs to manage network integrity and incentivise compliance across their members. Two of the most financially consequential are the Visa Acquirer Monitoring Program (VAMP) and Mastercard's Excessive Fraud Merchant Program (EFM). Both share a defining feature: the billing lag.
Under VAMP, which tightened its fraud-to-sales ratio threshold from 2.2% to 1.5% in April 2026, charges can reach $8 per qualified card-not-present (CNP) fraud or dispute notification once a portfolio crosses that line. EFM fines start at $500 per month but escalate to $100,000 per month as violations continue. The activity triggering these charges typically precedes the invoice by one to three months.
For a compliance team managing dozens of active bulletins, this is a fundamental information architecture challenge, and the organisation is being held financially accountable for decisions made months before the consequences surfaced.
The bulletin cycle
Scheme rules are updated continuously. Visa and Mastercard publish bulletins throughout the year: amendments, clarifications, new program criteria, threshold adjustments. Each bulletin may contain fee schedules, eligibility changes, opt-in/out or compliance windows that directly affect your exposure. See our guide to payment scheme compliance covering how to structure the process of operationalising bulletin updates at scale.
The challenge is not access to these bulletins, as most compliance teams receive them. The challenge is operationalising them. Knowing that a threshold has changed is not the same as understanding what that change means for your current portfolio, and surfacing the information to the people who need to act on it in time before the deadline.
The time between a bulletin publication and a compliance team analysing its financial implications and sharing it with the impacted teams can stretch into weeks. In a process where the billing lag can run on a one to three month cycle, that is a margin that rarely gets compressed.
When the invoice arrives
Consider what happens when a compliance team receives an unexpected compliance penalty or network charge. The first response is investigation: which transactions qualified, under which program, during which period. That period is often six to ten weeks prior. Operational decisions have already been made or not made. The data is historical. The fees, regardless of what the investigation reveals, have been assessed.
Some issuers or acquirers respond by building manual early-warning systems: spreadsheets tracking dispute rates by merchant, periodic sampling of transaction volumes, and monthly reviews designed to approximate what scheme monitoring programs already know. These systems are better than nothing. However, they are also resource-intensive, difficult to maintain, and dependent on individual knowledge rather than on the organisation as a whole.
The more sustainable response is to close the information gap before it becomes a billing event, which requires knowing, close to the moment a rule changes or a new mandate is published, what that change means for your specific portfolio.
A different frame on compliance
There is a tendency across the industry to treat non-compliance costs as a cost of doing business: necessary, unavoidable, and primarily reactive. Fines and fees are built into budgets, audit cycles are scheduled in advance, and remediation plans are typically developed only after charges have been assessed.
The financial logic of that model is increasingly difficult to justify. When EFM escalations reach $100,000 per month, and VAMP charges compound across a high-volume CNP portfolio, reactive compliance does not reduce costs, it merely defers the discovery of costs.
Tools that surface the financial impact of a bulletin at the point of publication rather than at the point of invoice shift the operational model. When a compliance team can see, in the week a bulletin is released, what a new threshold means for their current dispute rate, they have an actual decision window. Not a retrospective one.
Kajo surfaces bulletin-level financial impact alerts as each new scheme publication is released, including opt-in/opt-out fee exposure alongside the underlying compliance requirement so the question of "What does this cost us?" gets answered before the billing cycle closes.
The question worth asking
Scheme fees are not arbitrary. They result from a defined set of conditions that can be understood and anticipated. The relevant thresholds are publicly available, billing cycles are clearly documented, and the monitoring programs are designed to operate with transparency.
What is your current lag between a scheme rule change and your team detecting its financial exposure for your portfolio? If the answer is measured in weeks, the billing window may already be closing.
