The Automated Clearing House (ACH) is an electronic network for financial transactions in the United States. It provides a standardized, automated method of clearing and settling payments between accounts at different financial institutions. ACH processes large volumes of credit or debit transfers on behalf of participating banks, thrifts, credit unions, savings & loans associations, and small dollar credit unions.

ACH payment processing works by debiting and crediting an account electronically at the same time, resulting in a reserve held against each transaction. ACH is currently used for payroll, direct deposit of Social Security benefits, tax payments, vendor payments, 401(k) distributions, mortgage payments, online bill payments etc., as well as for payment of insurance premiums, medical expenses/bills etc.

ACH stands for Automated Clearing House, which is the electronic network that financial institutions use to send payment instructions to one another including direct deposit e-refunds, tax payments and vendor payments. The ACH system processes large volumes of credit or debit transactions on behalf of participating banks and credit unions. It clears and settles these payments electronically, which allows companies to make payments within a guaranteed timeframe for a much lower cost than other payment methods (checks and wire transfers).

The ACH system was originally developed in the 1970s as an electronic solution that would eliminate check handling by financial institutions. Today it is used by many companies for direct deposit of payroll, vendor payments and tax payments. ACH processing allows a company to make larger, more frequent transactions with a guaranteed timeframe for a much lower cost than other methods.

Most banks offer the service as either a free-of-charge or fee-based product depending on volume levels, number of transactions etc.

How does an ACH Transaction Work?

ACH transactions are initiated by the company either through their bank or directly using the Automated Clearing House network. The first step is to set up an ACH profile with a participating financial institution. Once this profile is created, the company will have all of the necessary information required for processing ACH payments. For example, this includes a bank account number and routing number to which the ACH deposits can be deposited into after being processed.

When setting up an ACH profile you will need the following information:

  • Name of Bank
  • Bank Routing Number (all 9 digits) or your NW1/MBIA Routing Transit Number
Bank Account Number (all 9 digits) or your Check / Investment Account Number

Once a company's ACH profile is set up, the next step is to send payment instructions to the participating bank which will include either a one-time transaction or recurring transactions. These instructions are passed through the Automated Clearing House network and are processed by the participating bank which will then deposit or withdraw the funds at their financial institution for payment.

ACH payments can be sent to other companies through ACH, but they must first set up an ACH profile with a participating financial institution using instructions similar to those mentioned above.

For non-recurring transactions, any company can initiate a one-time ACH payment through their bank or directly through the Automated Clearing House network. To initiate recurring transactions, you will need to set up an ACH profile with a participating financial institution and submit payment instructions for each recurring transaction.
