What Are The Types of ACH Payments?
ACH is the driving force behind most bank-to-bank money transfers, including payroll deposits, invoice payments, and more. What types of ACH transactions are available, and how do they work?
- ACH transactions fall into two main categories: credits that push money into an account and debits that pull authorized payments from an account.
- Same Day ACH can speed up eligible transfers, though banks and processors may set earlier submission deadlines.
- ACH payments, eChecks, and EFTs are related but not interchangeable; ACH and eChecks are both types of electronic fund transfers.
Automated Clearing House (ACH) payments are electronic bank-to-bank transfers used for direct deposit, bill payments, business payments, and account-to-account transfers.
Below, we’ll explain the main types of ACH transactions and how they move through the ACH network.

ACH Transaction Structure
ACH payments move between bank or credit union accounts through financial institutions and an ACH operator.
The sender’s financial institution submits the transaction in a batch to one of two ACH operators:
- The Federal Reserve, which operates FedACH
- The Clearing House, which operates the Electronic Payments Network
The ACH operator sorts the transactions and sends them to the receiving financial institutions, which credit or debit the appropriate accounts. The two operators exchange transactions so payments can reach accounts across the ACH network.
ACH files are processed through multiple windows each banking day. Settlement generally occurs on business days, not weekends or federal holidays.
Types Of ACH Transactions
ACH transactions fall into two main categories: credits and debits.
Same-Day ACH
Same Day ACH allows eligible ACH credits and debits to settle on the same banking day.
The final ACH operator submission deadline is 4:45 p.m. ET, although banks and payment providers may require earlier submission. Same Day ACH payments are currently limited to $1 million per transaction.
ACH Payment Codes
ACH transactions use Standard Entry Class, or SEC, codes to identify details such as whether a payment involves a consumer or business account, whether it is a credit or debit, and how it was authorized.
Businesses using a payment processor generally won’t need to select these codes themselves. Some of the most common include:
| SEC Code | Common Use |
|---|---|
| PPD | Consumer credits or debits authorized in writing, such as payroll deposits or recurring payments |
| WEB | Consumer payments authorized or initiated online or through a mobile device |
| TEL | Consumer debits authorized by telephone |
| CCD | Business-to-business credits or debits with limited payment details |
| CTX | Business-to-business credits or debits that include more detailed remittance information |
| IAT | ACH payments involving a financial institution outside the United States |
Other codes apply to specialized transactions, including electronic check conversion and re-presented checks.
ACH Payments VS eChecks VS EFTs
ACH payments, eChecks, and electronic fund transfers are related but not interchangeable:
- EFT: An electronic fund transfer is any payment that moves money electronically. It is a broad category that includes ACH payments, debit card transactions, ATM transfers, and some person-to-person payments.
- eCheck: An eCheck is an electronic payment that uses a customer’s bank account and routing information instead of a paper check. These payments are typically processed through the ACH network.
In other words, ACH payments and eChecks are types of EFTs, but not every EFT is an ACH payment or eCheck.
The Bottom Line On ACH Transaction Types
Whether you’re using ACH to credit or debit an account, ACH transactions provide a secure and low-cost method of moving money between accounts.
