What is an ACH payment? 

The Automated Clearing House, also known as ACH, is an electronic financial network in the U.S. that processes all kinds of financial transactions, including the direct deposit of checks, payroll processing, business-to-business (B2B) transactions, monthly debits, and other recurring payments. 

The ACH network is scheduled to process payments for more than 23 hours each business day, with payments settling four times a day. Because of its secure and efficient nature, ACH payments have become the preferred method of payment for many individuals, businesses and organizations, leading to a decrease in the use of cash, checks and paper transactions over time. 

ACH payments vs. ACH payment APIs

What's the difference between an ACH payment and an ACH payment API, you may ask? Well, they're completely different systems that work together to make ACH transactions possible. An ACH payment API is a software interface that allows developers to integrate ACH payment processing functionality into applications, websites or systems. 

Loaded with features and capabilities like data validation, authorization and security, error handling and seamless integration, payment APIs help facilitate the automation of ACH payments, making it more convenient and cost-effective for organizations to send and receive electronic payments efficiently. 

How to automate your ACH transfers

With an ACH payment API, you can set up recurring billing for your customers to save time, reduce errors and streamline your accounting process. 

Here's our guide on how to set up your ACH payment transfers:

1. Business account setup

  • First and foremost, ensure that your business has a bank account capable of sending and receiving ACH transactions. If not, you'll need to contact your bank to set up an ACH-enabled account. 

2. Select an ACH service provider

  • Once you've set up your bank account and obtained authorization, you can choose from various ACH service providers or financial institutions to automate ACH transactions. While many banks offer ACH services, ACH gateway providers and third-party payment providers are very popular these days.

3. Integration and configuration

  • Integrate your chosen solution with your bank or ACH service provider. This often involves configuring API connections or using provided SDKs (software development kits). 

4. Data collection

  • Gather all necessary payment information, such as bank account details (e.g. routing and account numbers) and the amount to be transferred. 

5. Security and compliance

  • Be sure that your system complies with security standards, such as PCI DSS and ACH regulations. Protect sensitive data like bank account information. 

6. Testing

  • Before going live, test your ACH automation system thoroughly to ensure accuracy and compliance with regulations. Use test accounts to simulate automated transactions. 

7. Monitoring and reporting

  • Implement a system to monitor all ACH transactions, track payment statuses and generate reports for reconciliation and audit purposes. 

8. Maintenance

  • Regularly update and maintain your ACH automation system to ensure it remains secure and is compliant with changing regulatory requirements.
