The number of electronic banking payments originated by financial institutions in the U.S. increased to more than 8 billion in 2002, up more than 13 percent from 2001. These payments were valued at nearly $22 trillion. Including payments originated by the federal government, there were a total of nearly 9 billion such payments in 2002 worth more than $24 trillion. The numbers have continued to skyrocket since then.

Until the 1990s, banking at the company level was heavily oriented to paper and the protection of check paper and other banking documents. The advent of electronic documents was embraced by the banking industry through the Electronic Payments Association that publishes the electronic banking payments standard for the United States (formerly called the National Automated Clearinghouse Association)—still called NACHA. It is a not-for-profit association that represents more than 11,000 financial institutions and 650 organizations through industry councils.

NACHA develops rules and practices for the Automated Clearing House (ACH) Network and an array of electronic type payments. The ACH Network is a payments network that provides the capability to transfer funds to your company's own bank accounts, clients, vendors, and employees without the wait and hassle of traditional paperwork. In 2005, the number of checks converted to ACH debits increased by 60 percent and the ACH network processed more than 2.2 billion consumer bill payments.

This electronic transfer of payment and deposit information permits tighter security over banking data and moves the money faster through the system. This has led to depositing receivables faster, paying payables on the exact date they are due, and getting employees paid directly into their personal or family checking accounts.

What is ACH?

ACH is a nationwide central clearing facility that processes your electronic banking transactions. The software runs on most commercial computers. There are several ACH software products that run on the AS/400/iSeries/System i, one of the most stable platforms available, a requirement for banking transactions. This "e-banking" software simply receives your company's electronic, pre-authorized debit and credit payments from your bank and routes them to the designated receiving banks.

ACH has permitted companies to transfer a wide variety of funds safely, reliably, and conveniently for years. With ACH you can transfer funds from your company's account to be used for your payroll, travel and expense reimbursements, bill payments, retail purchases, Internet purchases, corporate payments, treasury management, annuities, and pensions, dividends, and government payments such as Social Security and veterans benefits.
Standard characteristics of ACH software generally fall into the following areas:


  • Direct Deposit: Payments to your vendors, employees, and others. Automatically debit your customers recurring bills (they no longer will need to write and mail you checks, the ACH software takes care of it electronically). Also receive deposits from direct deposit of payroll, Social Security, and other government benefits.
  • Direct Payments: ACH payments include tax refunds; direct payment of bills such as mortgages, loans, utility bills, and insurance premiums; business-to-business payments; e-checks; federal, state, and local tax payments.
  • Funds Transfers: Transfer funds electronically between accounts.
  • E-commerce: Electronic payments for shopping cart purchases online.


  • Consolidation: Bring together your bank accounts through cash concentration and disbursement.
  • Speed: Reduce the processing time and related costs associated with traditional paper-based accounts receivable from your trading partners.


  • Notification: E-mail notification of deposits.
  • Monitoring: Extensive tracking and reporting features.
  • Integration: Often integrates with other e-doc software offered by the software vendor.
  • Security: Electronic management of funds reduces the risk of theft and fraud.

The NACHA Web site (http://www.nacha.org/) says the following:

The ACH Network is a highly reliable and efficient nationwide batch-oriented electronic funds transfer system governed by the NACHA Operating Rules, which provide for the interbank clearing of electronic payments for participating depository financial institutions. The Federal Reserve and Electronic Payments Network act as ACH Operators, central clearing facilities through which financial institutions transmit or receive ACH entries.
The NACHA Web site also offers the following chart, Figure 1,of the ACH check clearing house system.


Figure 1 shows the flow for e-banking transfers using the ACH Network. Above, the Originator is any individual, corporation, or other entity that initiates entries into the Automated Clearing House Network. The Receiver is the recipient of funds transferred through ACH. ODFI is the originating depository financial institution. RDFI is the receiving depository financial institution (click image to enhance).
