ACH vs Credit Card:
Which Should You Accept?
For a $3,500 invoice, ACH costs ~$3 and a credit card costs ~$100 in processing fees. Understanding when to use each can add tens of thousands of dollars to your bottom line each year.

The fee difference is significant at scale
A credit card payment on a $3,500 HVAC invoice costs you roughly $85–$120 in processing fees. The same invoice paid by ACH costs $1–$5. For a company doing $2M/year in card revenue, that's $40,000–$60,000 in fees that could be eliminated — or offset — by routing customers to bank transfer.
The flip side: credit cards have higher authorization rates than ACH, customers are more comfortable with them, and they fund your account faster in most gateway configurations. Neither method is universally better; the right mix depends on your average invoice size, customer type, and cash-flow needs.
Settlement speed: cards win on same-day liquidity
Credit card authorizations are instantaneous. Depending on your processor and payout schedule, you can see funds in your bank account the next business day — or even the same day with premium plans.
ACH transfers typically settle in 1–3 business days. Same-day ACH (NACHA's same-day rails) is available for transactions under $1 million but costs an extra $0.05–$0.15 per transaction, and not all processors support it.
For service businesses with tight cash flow — especially during slow seasons — the 1–2 day advantage of card settlement often outweighs the fee savings of ACH on smaller invoices.
Chargebacks vs. NACHA returns: different risk profiles
Credit card chargebacks can be filed up to 120 days after the transaction. Winning a chargeback requires evidence (signed estimates, communication records, delivery confirmation). Chargeback rates above 1% can put your merchant account at risk.
ACH returns work differently. Under NACHA rules, a customer has 60 days to dispute an unauthorized transaction, but the most common ACH returns are technical (NSF, account closed, invalid account number) — not fraud. Legitimate business-to-consumer ACH has a far lower dispute rate than credit cards in practice.
For recurring AutoPay, ACH authorization obtained up-front with proper disclosure is one of the most dispute-resistant payment methods available.
When to use each method
Use ACH for: recurring AutoPay enrollments, large invoices ($1,000+) where fee savings matter, customers who prefer not to give card details, and businesses where you have an ongoing relationship.
Use credit card for: first-time customers who haven't built trust yet, urgent collections where same-day authorization matters, customers who want card rewards, and lower-value invoices where fee savings are minimal.
A hybrid approach — presenting both options and nudging larger invoices toward ACH — is the most effective strategy for field service and MSP businesses. Win! shows both options at checkout and lets you set per-customer AutoPay preferences on either method.
