One thing I've learned after years of working with financial institutions is that ACH issues rarely happen because someone is ignoring the Rules. More often, they happen because everyone believes a responsibility is already covered. A vendor is handling it. Another department is reviewing it. A process was implemented years ago and has always worked.
Until one day, someone asks a question nobody has asked before.
Maybe it comes from an auditor. Maybe it comes from an examiner. Maybe it comes after a fraud event. Whatever the trigger, the answer is often the same: "We thought that was already being handled.”
When I work with financial institutions, I don't spend much time looking for dramatic failures. More often, I'm helping organizations identify blind spots, areas where risk has evolved, responsibilities aren't fully understood, or assumptions haven't been revisited in years.
If you're responsible for ACH operations, treasury management, payments risk, or compliance oversight, here are five questions worth asking.
1. Do You Know Exactly Where Your ACH Liability Begins and Ends?
This sounds like an easy question. In reality, it's one of the questions that generates the most interesting conversations.
I've worked with institutions that believed they were not acting as the ODFI for certain transactions, only to discover they still had responsibilities or contractual obligations tied to the activity. In other cases, an institution was relying on a third-party provider and assumed the associated risk transferred with the service. It didn't.
Understanding the transaction flow matters.
Understanding who's formatting the file matters.
Understanding who's responsible when something goes wrong matters.
Just because another organization is involved doesn't automatically mean responsibility has shifted. Sometimes the Nacha Rules assign responsibility. Sometimes a contract does. Sometimes both.
If someone asked you today to walk through the complete lifecycle of an originated ACH transaction, from initiation to settlement, could you clearly explain every party's role and responsibility?
If not, that's a good place to start.
2. Are You Certain Every Vendor Is Performing the Controls You Think They Are?
Most financial institutions rely on multiple vendors to support ACH-related services. Online banking platforms. Online account opening systems. Account-to-account transfer solutions. P2P payment services. Fraud monitoring tools.
Vendor relationships make these services possible, but they can also create assumptions. One of the most common things I see, is an institution believing a control is in place because one vendor performs it, while another vendor supporting a different service does not.
For example, an institution may have strong account validation controls within one channel but discover those same controls are not occurring somewhere else in the customer journey.
The question isn't whether you trust your vendors. The question is whether you fully understand what each vendor is, and isn't, doing.
As products expand and new services are added, that understanding becomes increasingly important.
3. If An Originator Is Acting as a Third-Party Sender, Would You Know?
This is one of the most misunderstood areas I encounter.
Many third-party senders are not trying to avoid their responsibilities. In fact, many don't realize they are operating as a Third-Party Sender in the first place. They're a payroll company. A property management company. A business service provider. ACH is simply one of the tools they use to serve their customers.
When those relationships aren't identified correctly, the consequences can ripple across the entire ACH origination process. Agreements may not align with the actual activity. Required oversight may be missing. Risk management expectations may not be clear. Audit and risk assessment obligations may be overlooked.
One of the most valuable things a financial institution can do is help business customers understand their role and responsibilities before a problem occurs.
A simple question can uncover a lot: "Are you sending entries only for your business, or are you originating payments on behalf of someone else?"
The answer may tell you much more than you expect.
4. Is Critical ACH Knowledge Concentrated in One Person?
Most institutions have employees who are incredibly knowledgeable about ACH operations. The challenge is what happens when they're unavailable. Someone is on vacation. Someone retires. Someone transfers departments. Someone is unexpectedly out for the week. That's when knowledge gaps become visible.
I've seen situations where exceptions, disputes, returns, or operational processes were handled incorrectly simply because the employee stepping in had never received the same level of training. The issue wasn't a lack of effort. It was a lack of knowledge.
That's why I believe training is one of the strongest risk controls available to a financial institution. Not because training satisfies a requirement. Because training builds resilience.
The strongest ACH operations teams don't have just one expert. They build knowledge across departments, ensure employees understand how transaction flows work, and create confidence that critical functions can continue even when key personnel aren't available.
5. Have You Reviewed Your ACH Risks Since Your Last Major Change?
Many institutions conduct their annual ACH audit and check the box. The audit gets completed. Findings are addressed. Everyone moves on. But ACH risk doesn't wait until next year's audit cycle.
Think about everything that may have changed in the last 12 months:
- A new vendor
- A new product or service
- Online account opening
- A core conversion
- New fraud monitoring tools
- New personnel
- New originators
- New Third-Party Sender relationships
Each of those changes can alter your risk profile.
An audit is important, but it's a snapshot in time. Risk management is an ongoing process. The institutions that maintain the strongest ACH operations are constantly evaluating whether their controls, processes, staffing, vendor oversight, and documentation still align with the services they're offering.
A Final Thought
In my experience, most financial institutions aren't struggling because they're careless. They're busy. They're managing growth, technology changes, evolving fraud threats, staffing challenges, and customer expectations, all at the same time.
That's why I encourage institutions to think beyond the question: "Are we compliant?"
Instead, ask: "What assumptions are we making?"
Because the most significant ACH risks are rarely the ones everyone is talking about. They're usually the ones everyone assumes have already been handled.
Not Sure Whether You Have a Blind Spot?
The challenge with ACH risk is that the most significant issues are often the hardest to see from inside the organization.
Whether you're evaluating a Third-Party Sender relationship, reviewing vendor controls, preparing for an upcoming audit, or simply looking for an independent perspective, NEACH Payments Group helps financial institutions identify potential blind spots before they become findings, losses, or operational challenges.
