From a Checkbox to a Differentiator: Redefining ACH Fraud Monitoring

Last year, the treasurer’s office in Warren County, New York sent $3.3 million to what it believed was the county’s roadwork and maintenance contractor. It was not—the payments were instead routed to a fraudulent account. Because the county had recently switched from paper checks to ACH, the treasurer’s office had no account verification policies in place to prevent what turned out to be a textbook case of fraud.

While the damage in Warren County represents the upper end of the spectrum, this incident is far from an outlier. It underscores the importance of implementing ACH protections, which many organizations already have in place. Too often, however, these measures are treated as a set-it-and-forget-it solution or merely a compliance checkbox.

In a recent PaymentsJournal podcast, John Gordon, CEO of ValidiFI, and Suzanne Sando, Lead Fraud Management Analyst at Javelin Strategy & Research, discussed how robust ACH fraud monitoring controls can do more than satisfy regulatory obligations—they can act as a proactive risk prevention mechanism. This is essential to combat the growing prevalence and complexity of fraud.

The Importance of Trust

The compliance aspect of ACH fraud monitoring is partly driven by the latest version of the WEB debit rule, instituted by Nacha—the organization that governs the ACH network. Nacha’s enhanced fraud monitoring requirements raise expectations for all participants in the ACH ecosystem.

“It increases the bar to say that we're not just checking the validity of the account, but we're also doing fraud checks,” Gordon said. “It creates an opportunity for financial service providers to identify fraud and to look at the potential risk associated with a consumer.”

“It moves beyond compliance for compliance's sake, which creates a lot of opportunities for financial service providers to not only identify and reduce fraud, but to put consumers in the right products that create mutually beneficial paths for them,” he said.

Finding the right fit with customers has become more challenging in the digital era, where consumers have more options than ever and increasingly expect efficiency in every interaction. As a result, consumers often choose the path of least resistance when selecting a financial institution.

These factors place institutions in a precarious position: they must balance security with customer expectations, both of which significantly impact retention.

“The importance of consumer trust cannot be overstated,” Sando said. “We're finding that when consumers have experiences with fraud or scams on a particular account—whether it's a traditional financial account like your checking or savings or a merchant account—if they've experienced any sort of suspicious activity or fraud and scams, they're much more likely these days to close an account where the fraud occurred and move somewhere else.”

Stepping Up Authentication

Given the risk of attrition, account onboarding and authentication have become critical stages in the customer experience. One key challenge arises from misapplied friction, where every user is forced to undergo the same verification process regardless of risk profile.

“Our belief is there's enough value in customer data that it can be managed through step-up authentication, that you are injecting friction where friction is warranted based on the risk signals that consumers have in concert with their profiles—whether that be their bank account, their payment transactions, or their credit scores,” Gordon said.

“There are a number of different ways to end up at the right answer so that you're facilitating a flow where the consumers stay in the process and you are fast tracking your low-risk consumers and putting obstacles in place where they should be,” he said.

This process can be optimized by leveraging the richer data available in a validated account. Institutions can go further by authenticating the account, confirming that the applicant’s name matches the account ow
