What Is ACH Merchant Processing? Benefits, Costs, and How to Get Started

Introduction

Looking for a more cost-effective way to accept customer payments? ACH merchant processing might be your answer. In 2025, businesses are embracing ACH payments as a secure, reliable, and low-fee alternative to credit card transactions. In this guide, we’ll break down what ACH merchant processing is, its key benefits, typical costs, and how to set it up for your business — so you can save money and streamline operations.

What Is ACH Merchant Processing?

ACH stands for Automated Clearing House — a U.S. financial network that moves money electronically between bank accounts. Governed by Nacha, the ACH system processes billions of transactions annually, ranging from direct deposits and bill payments to business-to-business transfers.

There are two main ACH types:

• ACH Credit: Funds are “pushed” from the payer’s bank account to the recipient.

• ACH Debit: Funds are “pulled” from the customer’s bank account with authorization.

ACH merchant processing allows your business to accept these payments directly, cutting out costly credit card fees and ensuring a smoother cash flow process.

Benefits of ACH Merchant Processing

Lower Transaction Fees

While credit card payments often cost 1.5%–3.5% + $0.30 per transaction, ACH fees usually range from 0.2%–1.5% or a flat $0.20–$1.50.
💡 Example: On a $500 transaction, ACH might cost $0.60, while a credit card could cost $12.74.

Predictable Cash Flow

ACH payments reduce payment declines caused by expired cards and can be automated for recurring billing — making it ideal for memberships, subscriptions, and invoicing.

Streamlined Operations

From payroll to supplier payments, ACH eliminates the hassle of paper checks and manual deposits, saving time and administrative costs.

Enhanced Security

Since funds move bank-to-bank with fewer intermediaries, there’s less exposure to fraud compared to card-based payments.

Costs Associated with ACH Merchant Processing

Per-Transaction Fees

ACH fees typically range from $0.20–$1.50 or 0.5%–1.5% of the transaction amount. Some processors (like Stripe) cap ACH fees at $5.

Additional Fees

• Return/NSF fees: $2–$5

• Chargeback fees: $5–$25

• Monthly fees: $5–$30 depending on provider

Same-Day ACH
