Quick answer: You can’t run a credit card directly on the ACH network, but a card-to-ACH funding service like Zil Money bridges the two: it charges your card, then sends your vendor a standard ACH deposit. Four details trip businesses up when they pay this way: the ACH transfer typically takes 1-3 business days even though your card is charged when you submit it, two separate fees stack on top of each other, your payment limit follows your card’s available credit, and the card balance is typically due in 30-45 days. Exact fees, limits, and billing-cycle timing depend on your card issuer and card agreement; the figures below are typical ranges, not guarantees.
Key Takeaways
How Does an ACH Payment With a Credit Card Work?
Credit card networks and the ACH network are two separate payment rails, so your card can’t be swiped directly into an ACH file. Here’s what actually happens: Zil Money charges your business credit card, then sends a standard ACH transfer to your vendor’s bank account on your behalf. Your card details aren’t part of that transfer. The vendor just gets a normal bank deposit. See the full walkthrough on the credit card to ACH payment page.
- Add a Visa, Mastercard, American Express, or Discover business card.
- Enter the vendor’s routing and account number. If you’re working from a vendor’s PDF invoice, you can also create checks directly from bills and invoices in PDF format instead of typing the details in by hand.
- Zil Money charges the card and starts the ACH transfer.
The mechanics are three steps. Where businesses lose money or miss a payment date is in the four details below.
Mistake 1: Assuming the ACH Transfer Lands the Same Day
Your card is charged when you submit the payment, but that is not when your vendor gets paid. A standard ACH transfer typically takes 1-3 business days to arrive, based on how the ACH network processes transfers. If you are trying to hit a rent due date or a supplier’s cutoff, submit the payment 2-3 business days ahead, not the day of. Same-day ACH is available for an additional fee if you are already up against a deadline, per Nacha’s Same Day ACH rules.
Mistake 2: Missing the Second Fee
Businesses often budget for the card processing fee and forget the ACH side has its own charge. Two fees apply on every payment: a card processing fee of roughly 2.5-3%, plus a flat ACH fee of about $1-5. Run the math before you commit a large payment to a card, especially if the rewards you’d earn are worth less than the combined fee. See the full worked example, including the $10,000 breakdown, in the fees-and-float breakdown.
Mistake 3: Treating Your Credit Limit as the Payment Limit
Your card’s available credit sets your payment limit, not the platform. Some businesses process anywhere from $500 to $500,000-plus per transaction, but that range only applies if your card’s available credit supports it. Check your available credit, not your total credit line, before you schedule a large vendor payment.
Mistake 4: Not Budgeting for the 30-45 Day Payback
The main appeal of paying a vendor by credit card is the float: you pay the vendor today and typically settle the card balance 30-45 days later, on your normal billing cycle. That is a real cash flow advantage, but only if you actually have the cash by the time the statement is due. Treat the float as a short-term bridge, not free money, and make sure the vendor payment fits inside what you can realistically pay off on schedule.

Frequently Asked Questions
Does my vendor need to accept credit cards?
No. Your vendor only needs a bank account that accepts ACH deposits. They receive a normal ACH transfer, and your card details aren’t part of it.
How long does the ACH transfer actually take to arrive?
A standard transfer, typically 1-3 business days after your card is charged. Build that lead time into any due date you’re trying to hit.
Can I get the payment there faster?
Same-day ACH is available for an additional fee if you’re up against a deadline. Standard delivery is the default and the cheaper option.
Are there fees beyond my card’s normal charges?
Yes. A card processing fee of roughly 2.5-3% and a flat ACH fee of about $1-5 both apply on every payment. Factor both in before sending a large amount.
Could this show up as a cash advance instead of a purchase?
It shouldn’t. A card-to-ACH vendor payment is processed as a standard card purchase, not a cash withdrawal, so it doesn’t carry the separate fee or lose the grace period that cash advances carry under a typical card agreement. If your statement description is ever unclear, ask your card issuer to confirm before you count on the float.
Which cards can I use?
Visa, Mastercard, American Express, and Discover business cards are all supported.
Is there a cap on how much I can send?
Your payment limit follows your card’s available credit rather than a separate platform cap. Confirm your available credit before scheduling a large payment.
Should I always pay vendors this way instead of by ACH from my bank account?
Not always. It makes the most sense when the float or rewards outweigh the combined fee, and when you’re confident you can pay off the card balance on schedule. For small, routine payments where cash is already on hand, a direct ACH straight from your bank account avoids the card fee altogether.
Used with the fee, timing, and payback math in mind, funding an ACH payment with a credit card is a straightforward way to buy a few extra weeks of cash flow on a vendor bill. Skip the math and it’s just an expensive way to pay someone a few days late.
