Credit and debit cards are convenient and provide fast transactions. However, merchants with high invoice amounts must contend with the costs of using these payment methods.
That is why more merchants are comparing ACH vs. credit card payment processing companies. Depending on the products or services a merchant offers, they may require both payment methods to provide an optimal consumer experience and maintain low transaction costs.
Why ACH Payment Processing Is Growing for Businesses
ACH payment processing allows you to move money between U.S. bank accounts via the ACH Network rather than card networks. ACH payments are often used for invoices, payroll, bill pay, subscriptions, memberships, and B2B transactions.
The ACH Network is already massive. According to Nacha, the ACH Network moved 35.2 billion ACH payments worth $93 trillion in 2025 alone. Same Day ACH processed 1.4 billion payments totaling $3.9 trillion. Many customers and other businesses are also very comfortable making ACH payments directly from their bank account.
ACH vs. Credit Card Payments: Key Differences Compared
ACH and cards solve different problems. Cards are usually faster and more familiar at checkout. ACH can be more cost-effective for larger invoices and recurring payments, but it requires stronger authorization and return monitoring.
| Payment Type | Best For | Main Strength | Main Risk To Manage |
|---|---|---|---|
| ACH / eCheck | B2B invoices, subscriptions, tuition, retainers, memberships and larger balances | Lower cost on many high-ticket payments | Returns, authorization and slower settlement |
| Credit Card | Ecommerce, retail, mobile, urgent orders and customer-preferred payments | Fast authorization and broad customer adoption | Interchange cost, chargebacks and fraud |
| Debit Card | Lower-cost consumer card payments and in-person transactions | Familiar customer experience | Still card-network based and subject to card rules |
| Same Day ACH | Faster bank payments where available | Better timing than standard ACH | Cutoff times, limits and bank support |
| Card + ACH Mix | Merchants that want flexibility | Lets customers choose while lowering cost where ACH fits | More reconciliation and reporting complexity |
The best setup often gives customers options. Cards can stay available for convenience, while ACH becomes the preferred method for larger invoices, recurring accounts or lower-margin transactions.
When Businesses Should Switch More Payments to ACH
Consider switching more payments to ACH if card fees are eating into your margins, if your average ticket size is high, or if customers are already paying you via invoice. ACH is good for anything that is recurring or business-to-business.
The larger the payment and the more predictable the revenue stream, the more you should consider ACH for that specific revenue stream. A $30 product order may not be worth the hassle of getting customers to switch from credit cards to bank payments. However, if you have a customer who pays you $3,000 monthly via invoice, authorizing them to pay you via ACH makes sense.
ACH Payment Processing for High-Risk Merchants
High-risk merchants often look at ACH due to the potentially high fees and other issues with card processing companies. Although ACH can help reduce a merchant’s dependence on card transactions, it is not without risk.
ACH payments can be returned for reasons including insufficient funds, authorization issues, account errors, revoked authorization, or disputes. High-risk merchants should be aware of these potential reasons for returns and take steps to avoid them.
NACHA’s WEB debit account-validation rule requires that merchants validate a customer’s bank account prior to the first use of that customer’s account information for ACH debit transactions online.
Best ACH Payment Processing Services Compared
The right ACH setup depends on ticket size, risk profile, billing model, software stack and whether ACH needs to work alongside cards.
| Provider Or Setup | Best Fit For | Key Strength | Main Tradeoff |
| Payment Nerds | High-risk and B2B merchants that need ACH plus card-processing strategy | Strong fit for ACH payment processing services, high-risk merchant account planning, recurring billing, invoices and chargeback controls | More consultative than a self-serve app |
| Authorize.net eCheck + Merchant Account | Merchants using Authorize.net for gateway and eCheck workflows | Familiar gateway, eCheck, recurring billing and virtual terminal support | Approval and terms depend on processor fit |
| NMI + ACH Processor | High-risk merchants needing gateway flexibility | ACH, card, recurring and processor-compatible gateway options | Requires configuration and underwriting support |
| Stripe ACH Direct Debit | Supported online businesses and platforms | ACH Direct Debit, bank verification and online payment tools | Restricted or higher-risk categories may need review |
| QuickBooks Payments | B2B and service firms already using QuickBooks invoices | Invoice payments, card payments and ACH inside accounting workflows | May not fit every high-risk merchant model |
| ACH + Card Merchant Account | Merchants that want both bank payments and card acceptance | Flexible payment mix and better cost control | More reporting and reconciliation work |
Payment Nerds is usually the strongest fit when the merchant needs help deciding where ACH belongs in the payment stack. ACH should not be bolted on randomly. It should connect to billing, accounting, customer authorization, returns and processor expectations.
How Visa VAMP Impacts ACH vs. Credit Card Strategy
The Visa Acquirer Monitoring Program (VAMP) is a Visa program that monitors for fraud and disputes. The VAMP ratio is a measure of fraud and non-fraud disputes relative to settled Visa transactions. Visa’s TC40 measure is its fraud report, while TC15 is its dispute or chargeback rate.
VAMP applies to Visa payments only. Because of this, some high-risk merchants use ACH to reduce reliance on credit cards for transactions. However, using ACH does not eliminate the bad customer experience. Customers can still have issues with a merchant that has unclear policies and return it.
Another piece of VAMP is enumeration monitoring. This occurs when bots use the customer’s credit card numbers to test the validity of those numbers on the website. Even with ACH in use, merchants should continue to monitor the reasons for fraud and chargebacks.
Common ACH Payment Processing Mistakes to Avoid
The biggest mistake people make with ACH payments is treating them as a cheaper alternative to using a credit card. However, there are different rules regarding the timing of authorizations, returns, and disputes for ACH payments than for credit cards. Before releasing goods or providing services, merchants must understand these rules.
Another common mistake is to move all customers to an ACH payment system at once. The best approach is to initially use ACH payments with customers with whom you have the most trust and for whom the benefit of using an ACH payment system is greatest. This would include business customers, customers who pay regular retainer fees, individuals who pay for memberships, and customers who already prefer paying their bills through their bank.
