How to Accept Card, ACH and Stablecoin Payments on Your Online Store
Most advice about payment methods is really advice about fees, which is the least interesting part. The percentage matters, but so does how quickly you can spend the money, whether it can be taken back weeks later, and whether the customer standing at your checkout can actually use the method you offered. Here is how the three main options differ, and how to decide what belongs on your store.
The real problem
A payment method fails you in one of four ways. It costs too much for the size of order you take. The money arrives too slowly for your cash flow. It can be reversed long after you have delivered. Or your customer simply does not have it. No single method wins on all four, which is the entire reason offering more than one is worth the effort.
How the three compare
Cards
- Who pays this way:
- Almost every consumer, and most first-time buyers.
- Speed:
- Funds typically settle in one to two business days.
- Reversal risk:
- Chargebacks are possible for months after the sale. The customer disputes through their bank and you have to respond with evidence.
- Relative cost:
- The most expensive of the three, because the card networks, the issuer and the processor all take a share.
- When to offer it:
- Offer these. For a public storefront selling to consumers, cards are not optional. Whatever else you support, a customer who cannot pay by card will usually just leave.
Bank payments (ACH)
- Who pays this way:
- US customers, particularly businesses and repeat buyers paying larger amounts.
- Speed:
- One to three business days, and slower to confirm than a card.
- Reversal risk:
- Far fewer disputes than cards, though returns can still happen for insufficient funds or a revoked authorisation.
- Relative cost:
- Usually much cheaper than cards on a large order, because the fee does not scale the same way with the amount.
- When to offer it:
- Worth offering when your average order is large enough that the card percentage genuinely hurts, or when you invoice other businesses.
Stablecoins (USDC and USDT)
- Who pays this way:
- Customers who already hold stablecoins, and international customers avoiding cross-border card and bank costs.
- Speed:
- Minutes, and confirmation is on-chain rather than a promise to settle later.
- Reversal risk:
- No chargeback mechanism. A completed payment is final, which is a genuine advantage for the merchant and a genuine responsibility too.
- Relative cost:
- Predictable, and it does not carry the card networks cost structure.
- When to offer it:
- Strong for international sales, for higher-value orders, and for any business that has been hit by chargeback fraud.

Chargebacks deserve their own paragraph
With cards, a customer can dispute a charge long after you have delivered. You lose the sale, you often lose the goods or the hours you already spent, and you usually pay a fee on top. For a small business a run of disputes is not just an accounting problem, it can threaten the payment account itself. That is the specific pain stablecoin settlement removes, because a confirmed on-chain payment cannot be pulled back by the payer. If you have been burned this way, reducing chargeback risk with stablecoins goes deeper.
A sensible default
For most storefronts: offer cards because otherwise you lose sales. Add bank payments if your typical order is large or you sell to other businesses. Add stablecoins if you sell internationally, take higher-value orders, or want settlement that cannot be reversed. Then leave the choice to the customer at checkout rather than guessing on their behalf.
How this works on SaturnShift
SaturnShift supports card, bank (ACH) and stablecoin payments in USDC and USDT on one account, with one dashboard and one set of reporting. That is the unified payments idea: rather than running a card processor alongside a separate crypto tool and reconciling them by hand, every payment lands in the same place.
If you do not yet have anywhere for customers to pay, Online Store builds you a hosted storefront with this checkout already in place, so you are not connecting a store to a payment provider as a second project. Which methods appear at your checkout depends on what is enabled on your account.
