A Career in Payments: Insights from Three Decades at Nacha

Few payments professionals have been able to observe and influence the industry as much as Jane Larimer, President and CEO of Nacha, who has helmed the organization that governs the ACH Network through challenging industry transitions and considerable organizational success.

In her nearly 31 years at Nacha, Larimer has seen firsthand the shift away from paper checks to moving payments at the speed of modern life.

During Larimer’s tenure, ACH has served as the national economic infrastructure. In 2025, the ACH Network processed $93 trillion. However, Nacha has not been content to coast on this success. Instead, the organization has continued to lead the payments conversation through innovation, education, and consensus-building.

In a recent PaymentsJournal podcast, Larimer discussed the biggest accomplishments and hurdles in her storied career, the many new projects on Nacha’s docket, and why—after over three decades—she is still excited to be a part of the payments industry.

The Accelerating Shift from Paper to Digital

Although the financial services sector has undergone a widescale digital transformation, it didn’t happen overnight.

“One of the first things that I think of among my accomplishments was there were still a ton of paper checks then, only maybe 50% of Americans got paid with Direct Deposit,” Larimer said. “There were billions of checks, so one of the first projects I did at Nacha was check conversion. What that meant was stripping the information off the MICR line of a paper check and then converting that into electronic payments—that was literally the first year.”

Also early in her tenure was an electronic benefit transfer (EBT) initiative aimed at moving from paper-based to electronic solutions. The goal was to reduce reliance on paper food stamps, which were high-risk for fraud and carried social stigma.

To address this issue, Nacha worked with networks, merchants, and financial institutions to shift the paper-based system to an interoperable state-issued card usable on debit card networks and at the point-of-sale. This effort ultimately led to the launch of the Quest Operating Rules and QUEST Service Mark.

For years afterward, Larimer and Nacha worked to grow ACH payments to be more vital than ever. In 2016, Nacha introduced Same Day ACH, providing the capability to send and receive ACH debit and credit payments within hours on the same business day.

“That was just a huge sea change in 2016,” Larimer said. “Everybody’s been saying this for a long time and we're always talking about the pace of change. Back in 2000 and then 2015 we thought that things were changing quickly, but what we're seeing is that pace of change has accelerated, and it's always going to be accelerating.”

A Momentous Year for Payments

This momentum isn’t slowing down, as faster payments, digital assets, and artificial intelligence continue to reshape the industry. Nacha is advancing a series of initiatives aimed at expanding capability while bolstering trust in the payments space.

One of the most significant developments is the planned increase of the Same Day ACH transaction cap from $1 million to $10 million—This enhancement is expected to broaden adoption by enabling a wider range of commercial use cases for what has already become a fast-growing payment method.

At the same time, Nacha has approved new risk management rules taking effect this year, reflecting a parallel priority: addressing the rising threat and volume of credit-push fraud. Together, these changes underscore a dual focus on scaling payment capabilities while reinforcing system integrity.

“We have a lot of irons in the fire,” she said. “We are working as hard as we can in conjunction with the industry to make the ACH as efficient as it possibly can be, and to meet the needs of the end users of the [ACH] Network and all the participants with the [ACH] Network—the financial institutions, our processors, our corporates, and consumers.”
