NACHA compliance and payment systems services for fintechs, banks, and payment companies

If your company originates, receives, or facilitates ACH payments, you are subject to the NACHA Operating Rules, and the compliance obligations that come with them. NACHA compliance requirements have expanded significantly, particularly with the March 2026 fraud rule that introduced new monitoring and control mandates for ACH originators and third-party senders.

Equinox Compliance provides end-to-end NACHA compliance and ACH compliance services: program design, TPS/TPPP audit preparation, fraud monitoring controls, return rate compliance, and payment system risk assessments for fintechs, banks, payment facilitators, and any entity touching the ACH network.

Whether you need a complete NACHA compliance program built from scratch, a third-party sender audit, or payment compliance consulting that covers ACH, wire, RTP, and FedNow rails, Equinox delivers the regulatory and operational expertise to keep your payment operations compliant and examination-ready.

NACHA, the National Automated Clearing House Association, governs the ACH network that processes billions of transactions annually in the United States. The NACHA Operating Rules and Guidelines establish the compliance framework for every entity that originates, receives, or facilitates ACH transactions: banks, credit unions, fintechs, payment facilitators, third-party senders, and payment processors.

What is NACHA compliance? It means adhering to the NACHA rules that govern how ACH transactions are originated, processed, returned, and monitored. This includes ACH origination compliance, return rate monitoring, fraud detection controls, data security requirements, and proper classification of your role within the ACH ecosystem.

NACHA regulations are not static. NACHA updates its operating rules regularly, and the NACHA rule changes in 2026, particularly the NACHA March 2026 fraud rule, represent the most significant expansion of fraud monitoring requirements in recent years. The new NACHA fraud monitoring requirements mandate specific controls for credit transactions, origination pattern monitoring, and suspicious activity detection. Examiners and bank partners are already incorporating these requirements into their oversight reviews.

For fintechs operating through bank partnerships, payment platforms classified as third-party senders, and any company originating ACH transactions, the compliance obligations are real, the examination scrutiny is increasing, and the cost of noncompliance includes return rate thresholds, ODFI exposure, and potential network suspension. Equinox helps you build and maintain the NACHA compliance program your business needs.

1. Assessment and classification: We evaluate your current payment operations, determine your NACHA classification (TPS, TPPP, originator, or other), and assess your compliance posture against current NACHA operating rules, the March 2026 fraud rule, and applicable payment regulations. We identify gaps, map obligations, and define the scope of the engagement.
2. Program design and documentation: We design your NACHA compliance program, build fraud monitoring controls, establish return rate monitoring frameworks, draft policies and procedures, and prepare the documentation your ODFI, bank partner, and examiners expect.
3. Implementation and testing: We implement compliance controls, launch monitoring programs, conduct initial NACHA compliance testing, and prepare your organization for audit readiness. If a TPS audit or NACHA compliance audit is required, we manage the full preparation process.
4. Ongoing management and monitoring: We manage recurring NACHA compliance deliverables including return rate monitoring, fraud control reviews, NACHA rule change tracking, audit preparation, and examination support. We refine the program as NACHA rules evolve and your payment operations scale.
