FAQs

What is the difference between ACH and wire transfer?

ACH transfers are batch-processed through the national clearing network: lower cost ($0.20–$1.50), next-day or same-day settlement, reversible, and have dollar limits. Wire transfers are real-time gross settlement (RTGS), processed individually and irrevocably: higher cost ($15–$50 domestic), immediate settlement, not reversible, and no practical dollar limits. Use wires for time-sensitive, large, or international transfers.

What is a Return Code in ACH?

An ACH Return Code is a standardized code used by the receiving bank to return an ACH transaction that cannot be processed — most commonly R01 (Insufficient Funds), R02 (Account Closed), R03 (No Account/Unable to Locate Account), and R10 (Customer Advises Unauthorized). Businesses must monitor return codes and have processes to handle rejected payments.

How long does it take for ACH payments to settle?

Standard ACH settles within 1–2 business days. Same-Day ACH (submitted before cut-off times, typically 2:45 PM ET or 4:45 PM ET) settles on the same business day. Note that even after settlement, banks may place holds on funds per their funds availability policies, so the payer's account is debited before the recipient has access to collected funds.

An ACH (Automated Clearing House) transfer is an electronic funds transfer processed through the ACH network — a nationwide electronic payments network operated by Nacha (formerly NACHA) connecting virtually all US financial institutions. ACH is the backbone of US electronic payments, processing over 30 billion transactions annually including direct deposit payroll, business-to-business payments, consumer bill payments, and government disbursements.

ACH transactions occur in two types: ACH Credits (push payments), where the originator instructs their bank to push funds to the recipient's account (e.g., payroll direct deposit), and ACH Debits (pull payments), where the originator pulls funds from the recipient's account with prior authorization (e.g., mortgage autopay, subscription billing).

Traditionally, ACH transactions settled on the next business day (Standard ACH) or within two business days. Same-Day ACH, introduced in phases since 2016 and now universally available, allows transactions submitted by specific cut-off times to settle on the same business day, significantly improving cash flow predictability.

ACH is significantly cheaper than wire transfers ($0.20–$1.50 per transaction vs. $15–$50 for domestic wires) but has lower maximum transaction limits ($1M per transaction for Same-Day ACH), longer settlement windows, and is reversible — unlike wires. The reversibility of ACH debits creates risk: payers can return an ACH transaction up to 60 days after authorization (for unauthorized debits), creating chargeback-like risk for merchants.

ACH is the payment rail underlying many fintech products: Bill.com uses ACH for vendor payments, payroll platforms route direct deposit via ACH, and most AP automation platforms default to ACH for domestic B2B payments.
