Are processing fees eating up a chunk of your profits? Are transaction fees adding up faster than you would like? It’s true that credit cards are convenient, but what if processing payments could be significantly more affordable? Enter: electronic checks.

You might have heard the terms “eCheck” or “ACH” thrown around by banks and payment processors. But what is an eCheck, and is it the same as an ACH payment? How are they different from the plastic cards in everyone’s wallets? More importantly, how can ACH payments save your business money?

What Is an eCheck?

If the word “check” still brings to mind putting a paper check into an envelope, well, you wouldn’t be too far off the mark. An eCheck (short for electronic check), simply put, is a digital version of a traditional paper check. eChecks apply the same traditional concept but move the process entirely online.

The funds are withdrawn electronically from the payer’s bank account and deposited directly into the payee’s account through the ACH network. It’s faster, more secure, and uses significantly less paper than the old-school method.

Understanding the ACH Network

You can’t talk about eChecks without mentioning ACH payments. While the two terms are sometimes used interchangeably, there is a slight technical difference.

ACH stands for Automated Clearing House. This is the electronic network used by financial institutions in the United States to transfer money between bank accounts. It is the road that the money moves along.

An eCheck is the vehicle that moves along that road. When a customer pays you via eCheck, that payment is processed through the ACH network.

If you’ve ever received a direct deposit paycheck or paid a utility bill online directly from your bank account, then you’ve already used the ACH network.

eCheck vs. Credit Card Networks

The most important difference between ACH payments and credit cards is how the money is transferred.

- Credit Card Networks: When a customer swipes a card, the transaction goes through card networks (like Visa or Mastercard). These networks charge interchange and assessment fees in exchange for authorization, fraud protection, and global acceptance.

- ACH Network: ACH payments move directly from bank to bank. By bypassing card networks and intermediaries, processing costs for eChecks are dramatically lower.

How Does an eCheck Payment Work?

The process of accepting an eCheck is refreshingly simple for both the seller and the customer. Let’s break it down:

1. Authorization: The customer authorizes the payment. This can happen online, over the phone, or via a signed contract. They provide their bank routing number and checking account number.
2. Processing: The payment information is entered into an online payment gateway.
3. Submission: The payment processor sends the transaction details to the ACH network.
4. Clearing: The ACH network transmits the payment to the customer’s bank, where it is processed.
5. Settlement: The funds are withdrawn from the customer’s account and securely deposited into the business’s bank account, typically within 2–3 business days.

Why Businesses Are Switching to eChecks

Credit card fees typically charge 2.9% + 30¢ per transaction. That might not sound like much on a $10 purchase, but on a $1,000 invoice, you’re losing nearly $30 just to get paid. By adding eChecks, you make savings of up to 70% on processing costs and provide your customers with a trusted and familiar way to pay.

Here are the top reasons merchants love eChecks:

- Lower Processing Fees: This is the big one. eChecks cost a fraction of what credit cards do.

- Fast Approvals: Getting set up to accept eChecks is often quicker and easier than setting up a merchant account.

- Fewer Payment Failures: Credit cards expire, get lost, or are reissued with new chips. Bank account numbers rarely change, meaning recurring payments are less likely to fail.

- Reduced Fraud Risk: eChecks are harder to use fraudulently compared to stolen credit card numbers.

Are eChecks Safe?

All business owners want to prioritize security for their customers. Protecting customer data reassures both you and your clients. Fortunately, eChecks are a highly secure method of payment.

All ACH payments are governed by NACHA operating rules and processed through a highly regulated banking network—the exact same system banks use for payroll and government bill payments, so you know that your client’s data stays safe.

Because the data is transmitted electronically and encrypted, there are far fewer touchpoints where information can be stolen compared to a paper check passing through the mail.
