ACH (Automated Clearing House) payments are electronic funds transfers processed through the ACH network — the US payment rail operated by NACHA (National Automated Clearing House Association). ACH is used for direct deposit, bill payment, payroll, and increasingly for business-to-business transactions.
ACH transaction types: - **ACH credit**: Pushes funds from one account to another (payroll direct deposit, vendor payments) - **ACH debit**: Pulls funds from a customer's account (utility bill autopay, loan payment, subscription billing)
ACH vs. credit cards: - **Cost**: ACH transactions typically cost $0.25–$1.50 per transaction vs. 1.5%–3.5% for credit cards - **Speed**: ACH takes 1-3 business days for standard processing; Same-Day ACH (available since 2016) settles same day - **Risk**: ACH has higher return risk (NSF, stop payment) but lower chargeback risk than credit cards - **Limits**: ACH transactions can be larger amounts without the percentage-based fees of cards - **Consumer familiarity**: Credit cards are more familiar for retail; ACH is standard for recurring and B2B
ACH return codes: When an ACH payment fails, it returns with a specific reason code: - R01: Insufficient funds - R02: Account closed - R03: No account/unable to locate - R10: Unauthorized debit - R29: Corporate customer advises not authorized
For high-ticket B2B transactions and subscription billing, ACH is often the most cost-effective payment option. A $10,000 invoice paid by ACH costs ~$1; the same invoice paid by business credit card costs $200+.
ACH payment acceptance can dramatically reduce processing costs for high-ticket or B2B transactions. Merchants who accept both credit cards and ACH give customers payment flexibility while reducing their own processing costs when customers choose ACH.
The main challenge with ACH: return rates (failed payments) require robust handling — retry logic, customer notification, and possibly a reserve for returns. NSF (non-sufficient funds) returns are the most common.
For recurring billing businesses (subscriptions, memberships, utilities), ACH is significantly cheaper than credit card processing for the same transactions.
A commercial cleaning company processes $500/month recurring invoices: - 50 clients × $500 = $25,000/month - Via credit card (2.2% effective): $550/month in processing fees - Via ACH ($0.50/transaction): $25/month in processing fees - Monthly savings using ACH: $525 - Annual savings: $6,300
ACH is a type of EFT (Electronic Funds Transfer). EFT is the broader category; ACH is the specific US payment network for bank-to-bank transfers. Wire transfers are also EFT but use a different network (Fedwire).
Standard ACH: 1-3 business days. Same-Day ACH: settles same day if submitted before cutoff times (typically 4:45 PM Eastern). International payments via ACH alternatives may take longer.
An ACH return occurs when a bank rejects the payment — most commonly for insufficient funds (R01), account closed (R02), or unauthorized transaction (R10). Returns typically arrive within 2-5 business days of the original transaction.
Yes. Most payment processors and ISOs offer ACH processing alongside credit card processing. You need to obtain proper authorization from customers (a signed ACH authorization form or electronic consent) before initiating ACH debits.
