In an era where the velocity of digital payments is matched only by the increasing sophistication of cybercriminals, the National Automated Clearing House Association (Nacha) has taken a decisive step to strengthen the integrity of the U.S. financial ecosystem. The organization, which serves as the steward of the ACH Network, recently announced a strategic partnership with Relish, a leader in AI-driven enterprise workflow automation. This collaboration designates Relish as a "Nacha Preferred Partner" specifically for account validation, fraud monitoring, and risk prevention—a move designed to curb the rising tide of business email compromise (BEC) and vendor impersonation.
The Core Partnership: A New Standard for Financial Controls
The integration of Relish into the Nacha Preferred Partner program marks a significant pivot toward proactive, real-time defense mechanisms within corporate payment cycles. As enterprises continue to migrate toward digital-first procurement and payment processes, the gaps in legacy verification systems have become glaring vulnerabilities.
Relish fills these gaps by embedding AI-powered automation directly into the enterprise resource planning (ERP) workflows. By moving beyond traditional, static validation methods, Relish provides real-time verification of bank account existence, ownership, and current status. This ensures that when a payment is initiated, it is destined for a verified, legitimate account, effectively creating a "defensible audit trail" that satisfies both operational efficiency and modern regulatory compliance requirements.
Chronology: Building Toward a More Secure Network
The journey toward this partnership is reflective of the broader evolution of the ACH Network.
- 2025 Milestones: The ACH Network processed a staggering 35.2 billion payments, totaling $93 trillion. With such immense volume, the pressure to maintain security while fostering speed became the primary driver for industry innovation.
- Early 2026: Financial institutions and regulatory bodies observed a spike in sophisticated "credit-push" fraud. Business Email Compromise (BEC) schemes, where attackers spoof vendor communications to redirect payments, reached a level of complexity that traditional manual verification could no longer contain.
- May 2026: Recognizing the need for a more robust defense layer at the point of origination, Nacha evaluated technology providers capable of scaling with the Network’s requirements.
- The Announcement: On May 13, 2026, Nacha officially named Relish a Preferred Partner, signaling a formal endorsement of AI-driven validation as a best practice for ACH users.
Supporting Data: The High Stakes of Payment Security
To understand the necessity of this partnership, one must examine the sheer scale of the ACH Network. As the backbone of the U.S. economy, the ACH system facilitates everything from Direct Deposits to business-to-business (B2B) payments.
With $93 trillion in annual transaction value, even a small percentage of fraudulent activity represents a systemic risk. The rise in "credit-push" fraud—where the payer is tricked into initiating a payment to a fraudulent account—has shifted the burden of security from the receiving bank to the originating organization.
Relish’s technology is designed to address the "ACH return rate" issue. By validating accounts before the payment is sent, companies can drastically reduce the incidence of misdirected funds. In the current landscape, the cost of remediating a misdirected payment—in terms of administrative labor, legal fees, and reputational damage—far exceeds the cost of implementing automated, real-time validation.
Official Responses and Strategic Vision
The partnership has been met with broad approval from both industry leaders and security advocates, who view it as a necessary evolution of the ACH framework.
Jane Larimer, President and CEO of Nacha
In her official statement regarding the collaboration, Jane Larimer highlighted the strategic imperative behind the move: "Reducing credit-push frauds such as business email compromise is a major focus for Nacha and for participants in the ACH Network. Nacha is pleased to welcome Relish as a Nacha Preferred Partner."
Her sentiment underscores a shift in Nacha’s role. Rather than acting merely as a rule-setter, Nacha is increasingly acting as a catalyst for technological adoption, ensuring that participants have access to the tools required to maintain security in a digital-first environment.
Ryan Walicki, CEO of Relish
For Relish, the partnership validates a core business philosophy that has been gaining traction among CFOs and Treasurers. "Becoming a Nacha Preferred Partner signals exactly what our customers already know: that accurate, real-time bank account validation isn’t a ‘nice-to-have,’ it’s a financial controls requirement," said Ryan Walicki.
Walicki’s commentary highlights the transition of account validation from a back-office administrative task to a front-line defense strategy. "As a Nacha Preferred Partner, Relish is positioned to help enterprises meet evolving ACH compliance demands before they become a liability."
Implications for the Industry: Why This Matters
The implications of this partnership extend far beyond the immediate technical integration between Relish and the ACH Network.
1. The Death of Manual Verification
For years, organizations relied on manual callback procedures to verify changes in vendor banking information. These processes were inherently slow, error-prone, and susceptible to the very social engineering tactics that BEC schemes exploit. By automating this process, companies can remove human fallibility from the verification chain.
2. Regulatory Compliance and Auditability
Regulatory bodies are increasingly demanding higher standards for financial controls. Companies that fail to implement robust validation procedures often find themselves in breach of internal policy or external audit requirements. The "defensible audit trail" provided by Relish allows companies to demonstrate to auditors that they have performed due diligence on every transaction, a critical capability in today’s heightened regulatory environment.
3. Strengthening B2B Trust
B2B payments represent a significant portion of the ACH Network’s growth. As businesses move toward digital transformation, the lack of trust in digital vendor communications has been a bottleneck. By ensuring that funds are directed to the correct, verified account, Relish is essentially lowering the "friction of trust" in B2B transactions.
The Role of Nacha’s Preferred Partner Program
Nacha’s Preferred Partner Program is not merely a marketing arrangement; it is a highly selective framework designed to vet and endorse technology providers that are fundamentally aligned with the strategic goals of the ACH Network.
The program focuses on:
- Security: Ensuring that the provider’s technology meets the high-security standards required by financial institutions.
- Interoperability: Verifying that the solution can integrate seamlessly with existing banking and ERP infrastructure.
- Innovation: Selecting partners that are pushing the boundaries of what is possible in payment processing and risk management.
By gaining this status, Relish joins an elite group of organizations tasked with maintaining the safety and speed of the ACH system. For enterprises, choosing a Preferred Partner provides a level of assurance that the vendor has been vetted by the very organization that governs the rails upon which their money moves.
Looking Ahead: The Future of Payment Integrity
The partnership between Nacha and Relish is a harbinger of a broader trend: the "intelligent payment" era. As AI becomes more deeply integrated into financial workflows, we can expect to see a decline in legacy fraud patterns, even as attackers grow more creative.
The focus moving forward will likely be on "preventative architecture." Rather than reacting to fraud after it has occurred, the industry is moving toward a model where the network itself—supported by partners like Relish—identifies and intercepts anomalous activity at the moment of creation.
For CFOs, IT departments, and risk officers, the message is clear: the tools to secure the corporate treasury are no longer optional. As the volume of ACH payments continues to climb toward the 40-billion-transaction mark, the organizations that will succeed are those that prioritize automated, real-time, and verifiable payment integrity.
Through this partnership, Nacha and Relish have set a new benchmark for what it means to participate in the ACH Network. They are moving the industry toward a future where "safe, smart, and fast" are not just aspirations, but the baseline reality for every transaction processed in the United States.
