Nacha has named nsKnox a Preferred Partner across account validation, risk and fraud prevention, and ISO 20022. The designation recognizes nsKnox’s role in helping businesses verify bank account information and reduce payment errors and fraud risks across the procure-to-pay process. Its PaymentKnox platform checks account ownership against banking system data both before account details enter an enterprise resource planning (ERP) system and again before payment release, targeting risks that can lead to misdirected ACH transfers, fraudulent payments, and avoidable returns.

nsKnox Joins Nacha Preferred Partner Program for Payment Risk Controls

Business-to-business payment fraud often exploits a gap between collecting bank account details and actually transferring funds. A supplier’s banking information may be inaccurate, outdated, or fraudulently changed, and errors can remain undetected until a payment is initiated. nsKnox is positioning its PaymentKnox platform to address that exposure, with validation checks at both supplier onboarding and payment release.

The designation brings nsKnox into Nacha’s Preferred Partner Program across three categories: Account Validation, Risk and Fraud Prevention, and ISO 20022. Nacha, which governs the U.S. Automated Clearing House (ACH) Network, says the program connects it with solution providers whose offerings align with its strategy for advancing the network.

Verifying bank details at two critical stages

According to Nacha’s announcement, PaymentKnox validates bank account ownership against authoritative banking system data before account details are entered into an organization’s enterprise resource planning (ERP) system and again before a payment is released. The goal is to reduce misdirected ACH payments, fraudulent transfers, and returns caused by inaccurate account information.

The two-stage approach addresses different risks. Initial validation can help identify problems when a business onboards a supplier or records payment instructions. A second check before release can help catch discrepancies that emerge later, including changes to banking information during an ongoing supplier relationship.

This matters because procure-to-pay workflows typically span several systems and teams. Supplier onboarding, invoice approval, master-data maintenance, treasury operations, and payment execution may not happen in the same application or at the same time. Controls applied only at onboarding can lose relevance if payment details are later altered.

nsKnox says its platform combines network-based account checks, direct bank-source verification, and an AI-powered agent that can conduct vendor-verification calls. These capabilities are intended to help finance and treasury teams verify banking details and maintain a record of verification activity.

The company’s approach does not remove the need for internal controls. Organizations still need processes for approving changes to supplier records, authenticating requests, escalating suspicious activity, and reviewing exceptions. Account validation is one layer of protection, not a guarantee that every fraudulent or erroneous payment will be prevented.

A wider focus on ACH security and risk management

Nacha’s Preferred Partner designation comes as payment providers and financial institutions continue to focus on risk management across the ACH ecosystem. The network supports direct deposits and direct payments reaching U.S. bank and credit union accounts. Nacha reported that the ACH Network processed 35.2 billion payments valued at $93 trillion in 2025, illustrating the scale of the system these controls help protect.

At that scale, inaccurate account data can create costs beyond the original transfer: returned payments, delayed supplier settlement, additional reconciliation work, and time spent investigating exceptions. Fraudulent payment instructions can also expose organizations to direct financial losses and operational disruption.

Nacha President and CEO Jane Larimer said risk management remains central to fighting fraud and protecting the ACH Network. For nsKnox, the designation provides an industry platform to contribute to discussions about account validation and payment risk. It should not, however, be interpreted as a guarantee of the product’s effectiveness or as an endorsement of every individual deployment.

Where ISO 20022 fits

ISO 20022 is also one of the three categories under which nsKnox has been named a Preferred Partner. The standard provides a common framework for structuring financial messages and exchanging richer payment-related information across systems.

In business payments, better-structured information can support interoperability, reconciliation, and the exchange of details needed by payment participants. But ISO 20022 and account validation address different problems: standardized message formats help systems communicate consistently, while account validation checks whether bank details correspond to the intended account.

The announcement does not specify a particular ISO 20022 implementation or product feature being launched alongside the designation. Organizations evaluating the offering should therefore distinguish nsKnox’s Preferred Partner category from any claim that a specific integration, certification, or implementation has been completed.

What finance teams should evaluate

The announcement reinforces a broader shift toward embedding payment controls throughout the procure-to-pay lifecycle rather than relying on a single check at the moment a supplier is added. For finance leaders, the practical questions are how widely account validation works across relevant banking markets, how quickly checks return results, how exceptions are handled, and how verification evidence can be retrieved during an investigation or audit.

Companies should also examine how a validation platform integrates with ERP and payment systems, how changes to supplier bank details are governed, and whether its controls fit the organization’s existing fraud-monitoring procedures. The value of an additional control depends on its coverage and how consistently it is used.

For nsKnox, the Nacha designation adds industry visibility across account validation, risk and fraud prevention, and ISO 20022. For businesses, the more important test will be whether layered validation reduces preventable payment errors and fraud exposure without introducing unnecessary delays into legitimate supplier payments.

Market Landscape

nsKnox’s designation sits at the intersection of B2B payment security, account validation, payment-data standards, and automated fraud prevention.

• Account validation: Verifying bank ownership before onboarding and payment release can help reduce errors caused by inaccurate or manipulated account details.
• Business payment fraud: Supplier impersonation and fraudulent bank-detail changes make verification controls an important part of procure-to-pay risk management.
• AI-assisted verification: Automated checks and vendor callbacks may reduce manual verification workloads, provided organizations maintain appropriate oversight and escalation procedures.
• ERP-integrated security: Embedding validation into supplier and payment workflows can help apply controls more consistently across finance operations.
• Payment standards: ISO 20022 supports structured financial messaging, while account validation addresses the separate question of whether payment details are correct.

What to watch: Businesses should look for measurable reductions in payment returns, successful integration with ERP and payment systems, reliable coverage across relevant banks, and clear evidence of how validation decisions are recorded.
