The Automated Clearing House (ACH) was established in the 1970s to facilitate funds transfer without using paper checks. It’s grown into an intra-bank messaging service that processes over 30 billion payments yearly using the ACH system in the United States. This article will explain how that works and its importance to your business. Some key takeaways to look for are: 

  • An ACH debit is an ACH transaction that “pulls” money from one bank account and moves it to another.
  • The National Automated Clearing House Association (Nacha) is the agency that sets the guidelines for the ACH network. 
  • Checks are ACH debits. Credit and debit card transactions are not.

What is ACH debit?

An ACH debit is a type of ACH transaction that “pulls” money from one bank account and moves it to another using the ACH network. The network batches and sorts ACH requests six times a day. The National Automated Clearing House Association (Nacha) regulates the process by setting rules and guidelines for banks to be part of the network. 

For a transaction to be classified as an ACH debit, the transfer request must be to “pull” money from an account. “Pushing” money out of an account is an ACH credit, not a debit. That’s an important distinction because it changes the roles of the sender and the receiver. The payee initiates an ACH debit. The payer initiates an ACH credit.     

How does ACH debit work?

An ACH debit is an electronic funds transfer (EFT), not a wire transfer. The main difference is that the Automated Clearing House only operates inside the United States, while wire transfers can be sent internationally using the SWIFT network. The clearance times, limits, and fees also differ. ACH debits have a $1 million daily transaction limit. 

Executing an ACH debit requires two parties. The transaction starts at the originating depository financial institution (ODFI). They process and batch requests to send to the ACH network, where they are sorted and bundled for delivery to the receiving depository financial institution (RDFI). The payee receives the funds when the ODFI and RDFI settle the transaction.      

Is ACH debit related to debit cards?

Credit and debit card transactions at FDIC-insured business and commercial banks are not ACH transactions. They’re electronic, but they operate on different networks. A credit or debit card can be used to withdraw funds at an ATM machine, purchase at a retail point of sale (POS) system, or pay for goods and services online.   

Are eChecks related to ACH debit?

Yes. eChecks are a form of ACH debit. They’re initiated at an ODFI to send a payment to an RDFI over the ACH network. ACH checks are widely considered one of the most secure forms of payment because they’re FDIC-insured and regulated by the Federal Reserve. They are a common way to move funds in business banking.  

If ACH debit is US-based, what does the EU use?

The European Union uses the Single Union Payments Area (SEPA) for bank-to-bank transfers. It closely matches the ACH system used in the United States, but most SEPA transfers are free if a currency exchange is not required. The European Payments Council (EPC) regulates SEPA and monitors international payments between SEPA and non-SEPA countries.  

What are the types of ACH debit?

Several traditional bank processes require ACH debits on the back end. These transactions start out as something different, like a paper check or point-of-sale retail transaction. They are converted into an ACH debit to facilitate the transfer of funds. Here are some examples: 

ARC (accounts receivable entry)

An ARC is a conversion of a physical check into an ACH debit. A common example is initiating the ACH transfer using the routing and account numbers in a paper check received in the mail. Vendors and retailers that accept images of checks sent by mobile phone also use this process. Those images are converted to requests for ACH debits.   

BOC (back office conversion)

Taking a check at the counter can cause a dilemma for businesses that don’t use traditional banks. An ACH debit to secure the funds for those checks is called a back office conversion (BOC). This is frequently used by companies that have accounts with digital banks or online business banking platforms like Rho.  

CCD (corporate credit or debit entry)

Corporate credit and debit entries are simple bank-to-bank transfers. The funds are debited from the account identified in the ACH request, and an ACH deposit is made to the receiving bank. Direct deposit payroll is an ACH credit example because funds are “pushed” from the company bank account. Receiving a payment would be an ACH debit because it’s a “pull.”

POP (point-of-purchase entry)

Your accounts payable department may be familiar with this one. POP converts a paper check received in person into an ACH transaction. The check is then voided and returned to the issuer. This eliminates the need for a trip to the bank, filling out deposit slips, waiting in line, etc. It’s a good example of converting an older, slower process into a modern one.    

POS (point-of-sale entry)

This can be confusing. A point-of-sale transaction using a debit card is not considered an ACH debit, but the transfer of funds from the credit card processor is typically done using the ACH network. There are several reasons this happens. ACH and EFT payments are generally more secure than other payment options, and processing companies prefer them.  

PPD (prearranged payment & deposit entry)

Putting your utility bills or credit card payments on autopay creates ACH debits that pull from your personal bank account. Businesses may also do this with vendors and suppliers. It’s listed on the company’s accounts payable sheet as a “prearranged” payment or deposit. The receiving party typically requests a signed authorization to do this.     

TEL (telephone-initiated entry) & WEB (internet-initiated entries) 

Some companies will accept a bank routing and account number over the phone as payment for goods or services. That information is used to create an ACH debit to move the money. The same process is used for internet-initiated entries (WEB). Entering your account information into an online payment form authorizes the ACH debit transaction.   

ACH debit security measures

ACH debit payments are processed in huge volumes on the ACH network. The security of ACH processing is what makes the payment system popular. It’s a safe way to make a direct payment into someone’s checking account without waiting several business days for a paper check to clear. Here are some of the security measures used to make that happen:

Authentication and authorization protocols

The ACH network has a built-in security protocol that requires the authentication of the payer’s account before the transaction can be authorized. Only after that can the funds be sent to the receiver’s account for disbursement. The authentication also includes verifying the sender’s bank by their routing number. The account number identifies the individual. 

Bank-level security protocols

Banks protect their servers with intrusion detection systems and firewalls. The ACH network has transaction monitoring systems to flag suspicious activity and prevent fraud. This is particularly important for paychecks and government agency checks like social security benefits, many of which are sent via the ACH network. This security protocol helps ensure people get paid. 

Encryption standards

Encryption technology has improved dramatically in the 21st century. The ACH network encrypts the debit or credit transaction and the sender's identity. Payment methods that originate from mobile payment apps may not offer that. Keep that in mind when making bill payments. Some electronic payments don’t go through the ACH network.

Data integrity checks

ACH security protocols make it difficult to alter data in transmission, but the network still uses data integrity checks at both ends to guarantee accuracy. Part of this is done at the beginning of the authentication process. The data is then checked again before the transaction is settled. Any evidence of a data breach could delay payment. 

Redundancy and disaster recovery efforts

The ACH network has a backup system that kicks in if there’s a system failure, natural disaster, or cyber attack. Disaster recovery plans are also in place to ensure that the system continues to operate even under the most extreme circumstances. If you want to learn more, Nacha offers several training programs, including an Accredited ACH Professional certification. 

ACH debit benefits

Most ACH debits clear in 1-3 business days, but Nacha has offered same-day ACH since 2016. That could be an option if you have a due date you need to make. Other benefits of ACH debits include lower fees, fewer errors, and enhanced security. Here’s a more detailed list:

Lower transaction fees

Credit card processing and wire transfer fees are significantly more expensive than ACH debits. Small businesses looking to save money should consider this when setting up online bill payments.

Efficient recurring payments

SaaS businesses that rely on subscription payments have learned the value of offering their customers an ACH debit option. The system is smooth and efficient, and redundancies and backup systems are in place to ensure you get paid. 

Fewer payment processing errors

The ACH network's built-in automation and safety protocols reduce the likelihood of human processing errors in payments. ACH data analytics are also simpler to track than a manual checkbook or bookkeeping ledger updated by a human each time a payment is made. 

Enhanced payment security

We’ve already discussed the ACH network's security protocols. The system is simply safer for small business owners who cannot afford to miss payments. ACH also protects sensitive client financial information, which is critical for achieving business longevity. 

Streamlined operations

When you use the ACH network, workflows are simplified. Much of the process is automated, and the rest is streamlined to eliminate wasteful or redundant efforts. Processing 30 billion payments yearly requires efficiency, and the ACH network has that. 

Access to robust data analytics

You can secure valuable analytics from ACH that will help you grow and scale your business. One example of this is the amount of recurring revenue you bring in. That number can be used to set the value of your business for potential buyers or investors.

Increased customer satisfaction

The ACH network can boost your business customer service rating by simply paying people when they expect it. 

Challenges associated with ACH debit

No payment system is perfect, but ACH debit is better than most. The challenges with it are typically due to user error or fraud. There are systems in place to prevent both, but your business may still run into one or more of the following problems:

Invalid account information

The ACH debit cannot be processed if the bank account or routing number is wrong. This is most often a simple mistake. The numbers could be transcribed wrong when transferred between parties or entered incorrectly on the keyboard.

Debit request returns

Debit request returns can happen due to insufficient funds, old account information, account closures, etc. Consider these a normal cost of doing business and factor them into a waste or return calculation.

Alternatives to ACH debit

ACH debits aren’t the only way to transfer money electronically. Several other options could be a good fit for your business. Here’s a list of some of them:

Wire transfers

If you need a fast turnaround, wire transfers are a same-day alternative to ACH debits. They can also be sent internationally using the SWIFT network

Payment card networks

Visa and Mastercard are payment networks that process a significant portion of electronic funds transfers. Their debit and credit cards are recognized worldwide.

Direct debit systems 

This is a common option for processing recurring subscriptions and monthly bill payments. SEPA, the EU counterpart of ACH, is a direct debit system.

Online payment services

Stripe, Square, and PayPal are all examples of online payment services. eCommerce and service businesses often use these services to process payments for goods and services. 

Mobile payments

Apple Pay and Google Pay are two common examples of mobile payment options. As contactless technology has improved, they've become increasingly popular.
