Best 6 ACH payment processing companies in 2025

When we think of business transactions, the majority of us probably think of utilizing cash, credit, or debit cards. Most big businesses accept major credit cards and pay hefty processing fees without a problem. But for startups that might have small budgets or are more carefully managing their cash flow, these fees can pile up.

On average, credit cards charge between 1.5% - 3% for each transaction. ACH payments offer small businesses and startups a payment alternative that works quicker than other forms of payment.

This blog post will explore the different options and help you find the best ACH processors for your business.

2. Stripe

‍

Stripe is a well-known transaction platform with a robust transaction system. Stripe offers corporate credit cards and ACH payment processing services. Businesses at any stage can use.

stripe for ACH payments. However, Stripe has a list of prohibited businesses they do not service, all of which fall within the “high-risk” category. Unfortunately, clients aren’t always flagged as high-risk until after they begin using Stripe’s processes to accept payments, so be sure to ask about this prior to onboarding.

Dharma and Stripe refer clients they cannot support to Payment Cloud because of their ability to handle higher-risk businesses. 

Merchants with a large percentage of card-not-present transactions are considered a higher risk. This is why other ACH processors like Dharma deny clients but refer over to PaymentCloud.

• High-ranking customer support

• Bank partnerships

• Virtual shopping cart integration for eCommerce businesses 

Cons

What are ACH payments?

ACH stands for automated clearing house network run by the NACHA (National Automated Clearing House). ACH payments have been around since 1974 as an electronic payment method. ACH is a batch network processing system used by large financial institutions like banks to process large quantities of different transactions from one bank account to another. 

Businesses use ACH processing systems when using direct deposit for payroll, and the IRS uses ACH for tax refunds and other government deposits. You can use ACH for recurring payments to cover operating and other business-related expenses. 

ACH payments vs. credit card payments

ACH transactions and credit card transactions have two key differences to consider. ACH transactions have lower transaction costs compared to credit cards. ACH transaction fees remain around 1% or $.30 altogether. 

Credit card processing runs on networks monitored by the card supplier, meaning there is a process of checking the card for the amount needed to trade. Once confirmed, the funds are guaranteed to be processed. ACH transactions are technically requests without a guarantee because they are sent in batches. 

Non-guaranteed payments only affect a business if they are choosing to accept ACH customer payments. If you're considering paying vendors and other business expenses with ACH payments, the batch payment process shouldn’t be too big of a worry. 

Monitoring ACH payments 

ACH payments are recorded in accounts payable or accounts receivable, depending on your company’s use of the ACH process. Each settlement needs to be accurately accounted for in your company’s books for a solid picture of your company’s financial standing. 

Tax purposes: When tax time comes, the IRS will scrutinize your income to determine the amount of income tax owed. Issues with the IRS lengthen the amount of time you’ll receive your refund, if applicable, and can tie up other cash if you owe more to the IRS. 

Vendor relationships: An error in the amount paid vs. the amount owed for expenses can result in late fees and a strained vendor relationship. If the error isn’t caught immediately, it can result in contract termination or higher fees that stack up over time.
