  • At first, a customer places a transaction order. This order can be placed physically (in person) or by transmitting a file of order request to a bank.
  • The bank collects all transaction entries for an Automated Clearing House that come from various customers (aggregating both physical and file-oriented).
  • Based on time-to-time, the bank generates a file and sends it to the Automated Clearing House either at the close of the day or in sequences around the day.
  • The ACH arranger aggregates the data furnished by the banks inside every sequence (typically Automated Clearing Houses have numerous sequences or cycles during the day).

  • It then lets every bank know regarding the net settlement sum for which they are accountable for the cycle.
  • The arranger makes sure or guarantees that the sums of the settlement are obtained from all partakers of the cycle to implement the cycle.
  • It subsequently notifies the destination bank about the transaction particulars.
  • At the time when the transaction reaches the destination bank, the bank carries it out. The transaction usually involves crediting the payment to the beneficiary account. At the same time, the bank of the customer placing the order debits the account of the ordering customer.
