Introduction to ACH Files

Are you tired of dealing with financial transaction hiccups? If you’ve had trouble with ACH payment rejections or errors in NACHA files, you know how incredibly frustrating the problem can be. Learning how to create an ACH file the right way, can be a game-changer for your business.

An Automated Clearing House (ACH) file is a behind-the-scenes powerhouse that ensures your money gets where it needs to go, fast and error-free. Used for everything from paying the electricity bill to issuing paychecks, ACH files are the unsung heroes of financial operations. They provide a secure, efficient way to transfer funds between banks, eliminating the need for slow and costly paper checks.

However, ACH files are complex, with a very specific format. Each line of an ACH file, known as a “record,” is exactly 94 characters long and is split into several “fields”. These files contain one or more batches of transactions and the records follow a specific order to ensure secure processing. Any mistake in these files can lead to payment rejections and disrupt your cash flow.

Understanding the Structure of an ACH File

To understand how to create an ACH file, let’s first delve into its structure.

The Format of an ACH File

An ACH file is a simple ASCII file with a fixed width. Each line in the file is precisely 94 characters long and is known as a “record” . The data in each record is organized into specific “fields” that are positioned at particular points within the line. This structure is strictly ordered and must be maintained for the file to be processed correctly.

The Different Records in an ACH File

There are several types of records in an ACH file, each serving a unique purpose and following a specific sequence:

  1. File Header Record: This record always begins the file and starts with “101” followed by the routing number of the originating (sending) bank. It includes a timestamp and the names of the originating bank and company.
  2. Batch Header Record: This record, beginning with “5”, introduces a new batch of transactions. It identifies the company as the originator and provides a description for the transactions in the batch.
  3. Entry Detail Record: Starting with “6”, this record contains information about the receiver, including their account details, and the specifics of the transaction.
  4. Batch Control Record: This record closes each batch, summarizing the transactions.
  5. File Control Record: The final record in the ACH file, it verifies the accuracy of the file by providing counts and totals.

Each record is identified by a unique single-digit “type code,” which allows you to determine the type of record by the first number in the line.

The Role of Standard Entry Class Codes in ACH Files

The Standard Entry Class (SEC) Code has a major role in the organization of transactions within an ACH file. It’s a three-letter code that indicates the payment type, such as a direct deposit or a bill payment. Certain data elements are captured at different levels within the ACH format (file, batch, or transaction). As such, certain transactions with identical SEC Code, effective entry date, company ID, and Batch descriptor are batched together.

Understanding the structure of an ACH file is the first step in creating one. In the next section, we’ll guide you through the process of creating an ACH file from scratch.

Step-by-Step Guide to Creating an ACH File

Learning how to create an ACH file is a game-changer for any financial institution. It’s an investment of time that pays off in the form of efficient, error-free transactions. Let’s start with the necessary details for ACH file creation.

Setting Up the Necessary Details for ACH File Creation

Before creating an ACH file, ensure that you have all the necessary details at your fingertips. These include your organization’s name, the name of your bank, and the routing number of your bank. You’ll also need the customer’s bank account details and the amount you wish to withdraw from the customer’s account.

Once you have all the necessary details, navigate to your financial software’s ACH file creation module. If you’re using software like ours at NachaTech, you’ll find this under Customers > Create ACH File.

Importing and Checking Control Totals of Records

Next, select the appropriate District, Cycle, Payment Date, and Period Balance. The District and Cycle fields are dependent on whether your organization uses districts and cycles.

Once the details are set, you’ll need to import the control totals of your records. Control totals ensure that your ACH file was generated correctly and includes the accurate number of entries and transaction totals.

Including Detailed Transactions in the ACH File

The heart of your ACH file is the detailed transactions, also known as the “Entry Detail Records”. Each entry detail record contains information about the receiver, the transaction details, and a unique trace number used to identify the entry.

To include these transactions, select the checkbox titled “Create Transfer File”, then enter the Electronic Pay File Name and select the appropriate Report Order.

Saving the ACH File to a Specified Location

Finally, after the ACH file is created, it needs to be saved to a specified location. The ACH file is a fixed-width, ASCII file, with each line exactly 94 characters in length. It’s important to save the ACH file in a secure location, as it contains sensitive financial data.

By following these steps, you can create an ACH file that will streamline your financial transactions, reducing errors and increasing efficiency. However, the process can be simplified even further with the right software.

Understanding the Differences Between ACH Files and Other Files

As you master how to create an ACH file, it’s also crucial to understand how these files compare and differ from other types of financial transaction files.

The Difference Between an ACH File and an ACH Prenotification File

An ACH file and an ACH prenotification file serve different purposes and contain distinct types of information.

An ACH prenotification file is used to verify the accuracy of customer details – particularly their name and bank account number. This file includes only customers who have been set up with direct payments and whose status is set to prenotification. The bank uses this file to confirm that funds are being withdrawn from the correct account. Should there be any errors in the prenotification file, you’ll need to correct them and resubmit the file to the bank.

On the other hand, an ACH file is used to facilitate the actual transfer of funds. This file includes customers who have been set up with direct payments and whose status is active. The bank uses this ACH file to electronically transfer funds from the customer’s bank account to the organization’s bank account.

How ACH Files Compare to Positive Pay Files and BAI/BAI2 Files

ACH files, Positive Pay files, and BAI/BAI2 files are all used in financial transactions, but they each serve different functions.

Positive Pay files are used to prevent check fraud. These files contain a list of checks issued by an organization. The bank compares this list against checks presented for payment to ensure they match.

BAI/BAI2 files are used for cash management and provide a comprehensive report of an organization’s cash position with the bank. They contain detailed information about the organization’s accounts, including account balances, deposits, withdrawals, and other transactions.

On the other hand, ACH files are used for electronic funds transfers, facilitating direct payments between banks.

By understanding these differences, you’ll be better equipped to manage your organization’s financial transactions and utilize the appropriate file types for different functions.

In the next section, we’ll look at how ACH files is evolving with NACHA’s new rules and the introduction of Same Day ACH.

The Future of ACH Files and NACHA’s New Rules

As we look into the future of ACH files, it’s important to understand the changes that are in store. The National Automated Clearing House Association (NACHA) is making significant changes to enhance the reliability, safety, and efficiency of the ACH network.

The Introduction of Same Day ACH and Its Impact on ACH Files

One critical change that NACHA is implementing is the extension of the Same Day ACH window. This will provide an additional two hours for transactions, extending the banking day. This is a significant development, especially for financial institutions on the west coast.

The Same Day ACH window of hours will be extended to include a new third window with a 4:45 p.m. ET deadline. This will assist all banks with returns as the current 4 p.m. window is rolled into this later same-day ACH window.

The feature of Same Day ACH is a game-changer, enabling the processing of ACH transactions on the same day, ensuring quicker payments and improved cash flow. However, note that not all transactions qualify for Same Day ACH, and certain conditions must be met.

NACHA’s New Rules for Account Validation for WEB Debits

Another significant change coming in the year is a new rule that makes explicit that account validation is part of a “commercially reasonable fraudulent transaction detection system” for screening WEB debits.

This new rule, which is effective from March 19, 2021, applies when using an account number for the first time or making any changes to existing ones. However, the rule remains neutral concerning any specific method or tools required.

These changes underline NACHA’s commitment to maintaining the integrity of the ACH network and protecting businesses’ interests. By understanding these changes and leveraging tools like NachaTech, businesses can position themselves for success in the evolving landscape of financial transactions.

In conclusion, the future of ACH and NACHA files looks promising, with advancements geared towards increasing efficiency, reducing fraud, and improving transaction speed. As we adapt to these changes, we at NachaTech are committed to providing you with the tools and knowledge you need to navigate this evolving landscape.
