How Does ACH Work?
A company/individual (Receiver) authorizes a company/individual (Originator) to initiate a transaction to their financial institution account.
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).
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)
ACH Operator processes transaction files from submitting ODFIs and distributes it to Receiving Depository Financial Institutions (RDFls).
The RDFI receives entries for its customer accounts and posts entries on the settlement date. Transactions are also reported on account statements
