This is an inside look at electronic payment processing through the Automated Clearing House network and is for educational purposes only.  There is no warranty, expressed or implied in connection with making this information available.  Electronic Funds Corporation is in no way liable nor responsible for omissions or errors, herein.

The Automated Clearing House (ACH) is an electronic payment network used by individuals, businesses, financial institutions and government organizations. Electronic ACH payments provide better cash management capabilities and lower costs than traditional paper payments. The nationwide network exchanges funds and information throughout the 50 states as well as the U.S. territories and Canada with participation by over 98% of the nation's financial institutions, including thousands of savings banks and credit unions. Efforts are underway for the development of a worldwide ACH Network -the Worldwide Automated Transaction Clearing House (W.A.T.C.H).

The ACH network allows funds to be electronically debited or credited to a company's or individual's deposit account. Currently these deposit accounts include checking and savings accounts. As of September 15, 2000, ACH credit transactions may be directed to loan accounts and ACH debit and credit transactions to financial institution general ledger accounts. ACH transactions carry basic entry details such as the individual name (except Point-of-Purchase transactions), financial institution routing number, account number, amount and effective date for the transaction. Additional payment information may be sent in expanded record formats called addenda records. The addenda may include payment-related information such as invoice number or shipping advice.

How Does ACH Work?

1.

A company/individual (Receiver) authorizes a company/individual (Originator) to initiate a transaction to their financial institution account.

2.

The Originator prepares information about the transactions that are to be                automated for its customers or employees and passes it along to an Originating Depository Financial Institution (ODFI). 

3.

The ODFI collects ACH transactions from participating companies, consolidates  the information and presents it to the ACH Operator. (The ODFI may retain     entries for its own account holders) 

4.

ACH Operator processes transaction files from submitting ODFIs and distributes it to Receiving Depository Financial Institutions (RDFls).

5.

The RDFI receives entries for its customer accounts and posts entries on the settlement date. Transactions are also reported on account statements

How ACH Funds Are Settled

Settlement is the actual transfer of funds for ACH entries between financial institutions provided by the Federal Reserve Bank. The net debit and credit positions of financial institutions are calculated and posted to the reserve accounts of financial institutions (or to the account of their correspondent).

The timing of settlement is based upon the effective entry date indicated on the ACH file and the time of its delivery to the ACH Operator. ACH debits may be delivered to the ACH Operator no earlier than one banking day prior to the settlement date. ACH credits may be delivered no earlier than two banking days prior to the settlement date.

When the ACH Operator processes an ACH file, the effective entry date is read and entries are settled according to that date. If the ACH Operator cannot settle on the effective entry date due to untimely file delivery, a stale date, weekend, or holiday, the ACH Operator will apply a settlement date of the next business day.

 What Is the Legal Framework for ACH?

Participants in the ACH network must abide by the ACH Rules published by the NACHA. The ACH Rules define the required methods, procedures and record specifications for the processing of commercial ACH transactions.

Federal Regulation E places additional obligations on the RDFI and defines consumer rights regarding all electronic payments. The Uniform Commercial Code Article 4A (UCC-4A) places requirements upon ODFls originating wholesale credit     (corporate) transactions as well as the RDFls that receive such entries. Federal Government payments must also conform with certain Codes of Federal Regulation commonly referenced in The Green Book.

 

Rules Affecting Originators

1.

Prior to the origination of an ACH transaction an Originator must: 

Enter into an agreement with the ODFI.

Obtain authorization from the Receiver. (For consumer debits the authorization must be in writing and a copy of the authorization must be provided to the consumer. For corporate entries, the authorization may take the form of a written agreement. )

Maintain the authorization up to 2 years beyond the life of a transaction. 

Send a non-dollar test entry called a pre-notification (optional). 

2.

The Originator must notify a consumer 10 days in advance of a change in the amount or 7 days in advance of a change in the posting date of an ACH debit

3.

The Originator cannot recall valid transactions after they reach the ACH Operator. Allowances are made, however, for the reversal of erroneous transactions. 

4.

Transaction file records must conform to ACH format specifications.

5.

Originators must not reinitiate payments that have been returned as unauthorized or are incorrect until the problem is solved; they may, however, reinitiate a transaction if the original entry was returned for insufficient or uncollected funds.

Rules Affecting ODFIs

1.

Prior to the origination of entries subject to UCC-4A (wholesale credits), the ODFI must make certain disclosures regarding Transaction Settlement, Security Procedures, Choice of State Law and Provisional Payment. 

2.

The ODFI also makes the following warranties that:

Originated entries are in accordance with a valid authorization.

Entries are timely; that each debit entry is for a valid payment.

Entries comply with the Rules.

The Originator has complied with PIN Management Security standards if applicable (such as for debit card transactions).

Transaction information complies with the Rules.

Reclamation entry information is accurate, complete and timely.

(ODFI warranties and liabilities apply to entries originated directly or through the use of a sending point to the ACH Operator.)

Rules Affecting RDFIs

1.

An RDFI may request a copy of an authorization from the Originator but is not required to keep authorizations on file.

2.

RDFIs must verify the account number on the pre-notifications they receive and must either return invalid pre-notification entries or send notifications of change to the ODFI which detail necessary corrections.

3.

RDFI may rely solely upon the account number for purposes of posting to a Receiver's account.

4

An RDFI must make funds available for consumer credit entries no later than the date of settlement. If entries are available by 5:00 p.m. on the day prior to settlement, funds must be made available at the opening of business on the settlement date.

5.

An RDFI may not post a debit entry to a Receiver's account prior to the settlement date.

6.

An RDFI must initiate any returned entries in accordance with procedures and deadlines provided by the ACH Rules.

Legal Agreements Necessary

Authorizations

All ACH transactions between Originators and Receivers must be backed by valid authorizations. Authorization requirements differ for the various ACH transactions. While a verbal or other non-written form of authorization is permitted for consumer credit transactions, a written authorization form provides proper authorization for consumer debits. This authorization must be readily identifiable as a debit authorization, the terms must be clearly stated and procedures for revoking authorization must be explained. The authorization may specify that transactions will be for a fixed or variable amount.

Corporate (non-consumer) applications require more complex agreements that address the processing of payment-related data or the transfer of large dollars. The required authorization is generally included within a trading partner agreement that defines the responsibilities of each party under the agreement.

 

Agreements

Originators must enter into an agreement with their Originating Depository Financial Institution. All participating financial institutions, by act of receiving or sending ACH entries, agree to comply with the applicable ACH rules and agree that those rules shall govern relationships between the sending and receiving institutions (and other parties involved in items covered by those rules). Financial institutions execute an agreement with the Federal Reserve Bank (or ACH Operator), that defines their processing relationship.

Originating companies are legally bound to comply with the ACH rules through written agreement with the Originating Depository Financial Institution. The rules as they apply to originating companies should be addressed in this agreement. The agreement binds companies to the ACH rules and covers such items as compensation, communication between the parties and error resolution.

How Are ACH Payments Used? Direct Deposit

Direct Deposit is used to disburse funds to consumer accounts. Direct Deposit of Payroll is the most widely used of the ACH deposit services. The feature is also used to distribute other recurring or one-time deposits. The U. S. Government uses Direct Deposit to disburse nearly 87% of Social Security benefit payments. Some other commonly used applications include:

Dividends

Pension Benefits ~ Interest

Commission Disbursements ~ Trust Disbursements

Expense Reimbursements ~ IRS Tax Refunds

Child Support Disbursements

Direct Payment

Direct Payment provides the ability to collect funds from consumer accounts. Companies with billing operations participate through the automation of bill payment entries. This application is used for recurring bills that are either regular fixed amounts, or varying amount bills, such as utility payments. Some examples  of Direct Payment applications include.

Insurance Premiums ~ Utility Bills

Mortgage Payments

Subscription/Membership Dues ~ Loan Payments

Monthly Pledges ~ Rents/Leases

Tuition Payments

Cash Concentration

Cash Concentration through the ACH is a widely used and profitable cash management function. Often used by companies operating branches or sales outlets, and local governments to accumulate funds rapidly into a central corporate account. Cash Concentration through the ACH may replace the use of depository transfer checks or expensive wire transfers. Overall, this system improves a company's total cash management capability.

Corporate Payments

Corporate Payment applications through the ACH network provide the ability to collect and disburse funds between companies. They are used by businesses paying one another for goods or services. These applications continue to grow and are currently being used by the U.S. Treasury Department in the Vendor Express program to pay government suppliers. 


Corporate Payments replace checks with an electronic process of debiting and crediting for invoices between the financial institutions of participating companies. ACH Corporate Payments allow payments to be accompanied by additional payment information, such as the details of the invoices being paid. This is done by adding an ACH addenda record to the payment format. Some commonly used applications for Corporate Payments include those listed below: 

Vendor Express Payments > Invoice Payments

Federal and State Tax > Trade Payments

Royalty Payments > Debt Repayment

Financial Electronic Data Interchange (FEDI)

FEDI is an enhancement to Corporate Payments, which utilizes the ACH addenda record. It provides for the exchange of machine-readable documents and information between businesses. For example, a payment may be sent to a vendor with details of the invoice being paid in an electronic format for automated posting to a receivable accounting program. FEDI is also used with zero-dollar transactions to exchange information such as requests for quotations, order placements and shipment advice's.

Customer Initiated Entries

Telephone bill payment services are a common application of the ACH network's Customer Initiated Entry option. This application provides the ability for a consumer to initiate non-scheduled payments to a company or consumer account. Payment information may be submitted manually, by the consumer, to the ODFI or through a mechanical device (i.e., telephone, ATM or computer).

Re-presented Check Entries

A re-presented check entry is an ACH debit application used by Originators to collect funds for paper checks that have been processed through the check collection system and returned due to insufficient or uncollected funds. Originators of re-presented check entries must provide notice to the check writer, prior to the receipt of the check, informing the check writer that any insufficient or uncollected funds returned checks might be collected electronically. An interim rule effective September 18, 1998 through September 14, 2000 provides a rules framework for transmitting these entries using the PPD standard entry class code. Effective September 15, 2000, a new SEC code of RCK was established to be used to re- present insufficient or uncollected paper checks electronically.

Point-of-Purchase Entries

A point-of-purchase entry is an ACH debit application, used by Originators (merchants, billers, etc.) as a method of payment for the in- person purchase of goods or services by consumers. These non-recurring ACH debits entries are initiated by the Originator based on a written authorization and account information drawn from the source document (check or share draft) obtained from the consumer at the point of sale. The source document, which is voided and returned to the consumer at the point of sale, is used to collect the consumer's routing number, account number and check serial number that will be used to generate the debit entry to the consumer's account. An interim rule effective September 17, 1999 through September 14, 2000, provides a rules framework for transmitting these entries using the PPD standard entry class code. Effective September 15, 2000, a new SEC code of POP will be established for the transmission of point-of-purchase entries.

Lockbox Truncation (Accounts Receivable Conversion - ARC)

Consumers mail their bill payments to companies, realizing some advantages of mail and collection float associated with such payments. For companies, the cost of processing and collecting these checks is high. There are methods that remittance processors or billers may use to increase efficiencies within the lockbox or biller's process by reducing collection float and other check float collection costs, through the truncation of paper checks to electronics via the ACH.

Truncation in this instance means that the payer issues a paper check and sends it through the mail to the payee; at the point of receipt (Lockbox), the check is converted to an electronic payment. Presentment is made to the payer’s financial institution electronically and the paper check or image is stored for a legally specified period of time by the remittance processor.
