Quick Answer
ACH payments move money directly between bank accounts and typically cost less per transaction than credit cards, but settle more slowly (often 1-3 business days versus near-instant card authorization) and carry different dispute protections. Credit cards cost more per transaction but settle faster and are what most consumers expect for everyday purchases. Most businesses benefit from offering both, matched to transaction size and customer type. Want help deciding which to prioritize? Reach out to our team at Argent Payments.
Introduction
ACH and credit card processing solve the same basic problem — moving money from a customer to your business — but they work through entirely different systems with different costs, speeds, and use cases. Choosing between them (or, more often, deciding when to use each) depends on your transaction sizes and who you're billing.
Key Takeaways
- ACH moves funds directly between bank accounts; cards route through the card networks
- ACH typically costs less per transaction, especially on larger amounts
- Credit cards settle faster and are the default expectation for most consumer purchases
- ACH is well suited to large invoices, B2B payments, and recurring billing
- Many businesses benefit from offering both rather than choosing just one
How Each One Actually Works
A credit card transaction routes through the card networks (Visa, Mastercard, etc.) to the customer's issuing bank, which approves or declines the charge within seconds — but the underlying interchange and network fees apply regardless of transaction size, as we break down in how much payment processing actually costs. An ACH transaction moves directly between the customer's bank account and yours through the ACH network, without card network involvement, which is why it typically avoids interchange fees entirely. The trade-off is settlement time: ACH payments generally take one to three business days to clear, compared to near-instant card authorization.
ACH vs. credit card processing
| ACH | Credit Card | |
|---|---|---|
| Typical cost | Flat or capped fee, no interchange | Percentage + per-transaction fee (interchange + markup) |
| Settlement time | 1-3 business days | Same-day authorization, funds typically in 1-2 days |
| Best for | Large invoices, B2B, recurring billing | Everyday retail and consumer purchases |
| Dispute process | Bank-level dispute, generally slower | Card network chargeback process |
What Argent Looks For
When we help a business decide between ACH and cards, we look at their average transaction size. On a $50 purchase, the cost difference between ACH and card processing is negligible; on a $5,000 invoice, it's substantial enough to be worth actively steering customers toward ACH.
When to Use Each
For everyday consumer purchases — retail, restaurants, most e-commerce — credit cards remain the expected default, since customers are used to tapping or entering a card and rarely carry bank account numbers for spontaneous purchases. For B2B invoicing, larger contracts, and recurring billing relationships, ACH often makes more sense: the cost savings compound with transaction size, and business customers are generally comfortable providing bank details for a recurring arrangement. See what payment methods your business should accept for how this fits into your broader payment mix, and how to set up recurring billing if ACH fits your subscription model.

How Argent Payments Approaches This
We set most businesses up with both card and ACH acceptance, then help steer larger transactions toward ACH where it makes financial sense. See our ACH payments solution and our credit card processing solution for how the two work together.
Frequently Asked Questions
Is ACH always cheaper than credit card processing?
On a per-transaction basis, generally yes, since ACH avoids the interchange fees built into card processing. The exception is very small transactions, where a flat ACH fee can occasionally exceed what the equivalent card transaction would cost — compare the actual numbers for your typical transaction size.
Can I require customers to pay by ACH instead of card?
For B2B invoicing and recurring contracts, yes, many businesses do require or strongly prefer ACH. For consumer-facing retail or e-commerce, requiring ACH instead of cards is uncommon and can reduce conversion, since most consumers expect card payment as an option.
How long does it take for ACH funds to actually reach my account?
Standard ACH transfers typically take one to three business days to settle. Some processors offer same-day ACH for an additional fee, which settles faster but isn't universally available or free.
What happens if an ACH payment is returned or fails?
ACH returns (similar in concept to a bounced check) happen when there are insufficient funds or invalid account details. The dispute and resolution process differs from card chargebacks and is generally handled at the bank level rather than through a card network dispute process.
Do I need separate technology to accept both ACH and credit cards?
Not necessarily — many payment processors, including Argent, support both payment types through the same gateway or virtual terminal, so you're not managing two separate systems for two payment methods.
