Two very different payment rails, each with tradeoffs
ACH (Automated Clearing House) transfers move money directly between bank accounts, while credit card payments run through the card networks and involve interchange, assessments, and processor fees. For recurring billing, B2B invoicing, or large-ticket transactions, the cost and settlement differences between the two can be significant. This guide compares ACH and credit card payments on cost, speed, and customer convenience so you can decide whether to offer one, both, or steer customers toward a preferred method.
A credit card transaction authorizes instantly and settles into your account within roughly one to a few business days, with the customer able to dispute later through their card issuer. ACH debits a customer's bank account directly, typically settling in one to a few business days as well, but usually at a flat or capped fee rather than a percentage of the sale.
Credit card processing costs scale with the transaction size (a percentage plus a small flat fee), which can make card payments expensive for large invoices. ACH is often priced as a flat fee or a capped percentage, making it comparatively cheaper for high-ticket B2B payments.
On a $5,000 invoice, a card payment at a hypothetical 2.9% + $0.30 would cost about $145 in fees. The same payment via ACH at a hypothetical flat $5 or capped 0.8% fee could cost a small fraction of that. For recurring high-ticket billing, this difference compounds quickly — figures are illustrative, not fixed rates.
Card payments are generally faster for the customer to initiate, don't require sharing bank account/routing numbers, and offer built-in dispute protections consumers are used to — all of which matter more for consumer-facing, lower-ticket transactions than for B2B invoicing.
Many B2B and subscription businesses offer both options and let the customer choose, sometimes incentivizing ACH for large invoices given its lower cost, while keeping card acceptance available for convenience and smaller transactions.
Settlement times are often similar (a few business days), though ACH can sometimes take slightly longer depending on the bank and processing schedule.
Yes, but the process (an ACH return) works differently than a card chargeback and generally has narrower grounds for reversal.
It's less common for point-of-sale retail since it requires sharing bank details and isn't as instant-feeling as tapping a card; it tends to fit invoicing and recurring billing better.
Many providers support both, letting you manage a single dashboard for card and bank-transfer payments.
