ACH
Learn how U.S. ACH payments move through originators, banks, and ACH operators, including credits, debits, timing, returns, authorization, and risks.
ACH, electronic fund transfer, and bank transfer concepts classified by instruction, rail, settlement, and posting status.
ACH, EFT, and bank-transfer terms describe different layers of electronic money movement. Electronic fund transfer is the broad category, bank transfer is the account-to-account instruction, and ACH is a specific U.S. payment network.
Use these pages when a transfer record must be classified by rail, authorization, account movement, settlement timing, or dispute evidence.
| Term | Use it for |
|---|---|
| ACH | U.S. ACH credits and debits, ODFI and RDFI roles, operator processing, authorization, settlement, posting, and return status. |
| Bank Transfer | General transfers between bank accounts, including internal and interbank movements. |
| Electronic Fund Transfer (EFT) | Electronic movement of funds and consumer or account-transfer context. |
Start with the actual instruction and rail evidence rather than the statement label. “EFT” is broad, ACH is a specific network, and bank transfer can describe several operational paths.
Use the ACH guide for a complete payment flow, a reconciliation example, comparisons with instant payments and wires, and an investigation checklist.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.
