How does ACH payment processing work for merchants?

Payment efficiency directly impacts daily operational performance. How your business accepts payments matters just as much as getting paid.

Strong cash flows are critical for business success – acting as the thermometer you use to monitor the health of your operations and as the safety net for surprise expenses. That’s why it is critical to create and maintain a strong cash flow management strategy that includes forecasting, payments optimization, and more.

However, any business can generate strong sales and still face cash flow challenges, due to typical operational hurdles like:

• Paper checks delaying deposits
• Credit card processing fees reducing margins
• Manual payment reconciliation consuming valuable staff time

Sound familiar? That’s why business owners need a variety of funding tools to support their cash flow management strategy and ensure they are prepared for any unexpected costs. One helpful tool is Automated Clearing House (ACH) payment acceptance. This enables businesses to collect funds securely and electronically from customer bank accounts without relying on cards or paper checks. ACH is commonly used for payroll, billing, vendor payments, invoices, subscriptions and more. For companies managing recurring billing, large invoice volumes or ongoing customer payments, ACH offers a reliable, lower-cost way to get paid while improving cash flow and reducing administrative work.

How it works

For most merchants, ACH payments provide a reliable, cost-effective way to move money directly between bank accounts. Once a customer authorizes an ACH payment, the merchant’s bank sends the request through the secure U.S. banking network.

Here’s a step-by-step process of how ACH works:

1. Payment is requested: A merchant starts the payment by sending the customers’ ACH payment authorization to their depository bank.
2. Transactions are grouped together: The bank bundles multiple ACH payments into batches and sends them to an ACH operator (either the U.S. Federal Reserve or The Clearing House).
3. Payments are sorted and sent: The ACH operator processes the batch and sends each payment to the correct receiving bank.
4. Money is deposited or withdrawn: The receiving bank adds or removes the funds to support the customers’ ACH payment authorization from the customer’s bank account. Most ACH payments are completed within one to three business days.

Unlike credit card payments, ACH transactions typically come with lower processing fees and costs. For merchants looking to cut costs, automate recurring billing, or handle higher-value transactions efficiently, ACH payment acceptance is an important tool.

Types of ACH transactions

The two types of ACH transactions include ACH debit and ACH credit.

• ACH credit pushes funds into a recipient’s bank account. This transaction is used for direct deposit of paychecks and government payments.
• ACH debit pulls funds from a customer’s bank account. This type of transaction is used for business-to-business (B2B) payments, subscriptions or recurring bills, online shopping and services like Venmo and PayPal that use ACH to initiate transfers between bank accounts.

ACH payments can be accepted as easily as credit or debit cards. Bank account payments offer customers a direct payment option without the concern of remembering PIN numbers or worrying about having an accepted card type.

Core benefits of Elavon’s ACH payment processing

Elavon provides ACH payment processing designed to help businesses reduce costs, improve cash flow, and automate payments while maintaining strong security and compliance standards.

• Lower costs and predictable pricing: ACH offers lower acceptance fees than credit card interchange. Pricing remains predictable for high-volume and recurring billing.
• Improved cash flow: Funds settle faster than paper checks. Automated scheduling helps reduce late or missed payments.
• Increased operational efficiency: Recurring ACH payments process automatically for subscriptions and installments. Businesses make fewer bank trips and handle less physical paperwork. Reporting and reconciliation are streamlined through integration.
• Stronger security and compliance: The ACH network operates under NACHA (National Automated Clearinghouse Association) regulations. There is less risk of lost or stolen checks. ACH reduces exposure compared to storing credit card data and supports built-in compliance requirements.
• Convenience for you and your customers: Customers authorize payments once for automatic and recurring billing. This helps eliminate many late payments. Secure online portals make access simple and convenient.
