Accepting cards, ACH, and stablecoins from one integration

Three rails, one integration

Most businesses end up wanting more than one way to get paid. Cards are universal, ACH is cheap on large amounts, and a growing set of customers want to pay in stablecoins. The usual path to supporting all three is to bolt together separate vendors, each with its own integration, its own reporting, and its own reconciliation headache.

Flux takes the opposite approach: cards, ACH, and stablecoins through a single integration. If you want to accept stablecoin payments for your business without standing up a parallel system alongside your card processing, this is the shape of the solution. One integration, one set of records, three ways to pay.

When each rail makes sense

The rails are complements, not competitors, and each has a natural home. Cards are the default for everyday consumer purchases, where universality and speed matter most. ACH bank transfers shine on large or recurring payments, where a flat percentage on a big amount would be needless cost and the payer thinks in bank-to-bank terms anyway.

Stablecoins fits customers who prefer it, cross-border situations where it can be simpler, and cases where instant settlement to your own wallet is genuinely useful. Offering all three lets the customer choose the method they are most comfortable with, which removes friction at exactly the moment you least want it, checkout.

How does stablecoins settlement differ?

The settlement timing is where stablecoins stands apart, and it is worth being precise. Card payments settle in one to two business days. ACH settles in one to three business days. Stablecoins settles to the merchant wallet instantly.

That instant settlement is a real operational difference. There is no multi-day float between the customer paying and the funds being yours; the money arrives in your wallet at the time of payment. For a business that values immediacy, or that operates where the banking calendar is a constraint, that is a meaningful property rather than a novelty.

One set of books, not three

The strongest argument for one integration is not the payment page; it is everything after it. When three payment types flow through a single platform, they land in one consistent stream of reporting instead of three disconnected exports you have to merge by hand.

That unified view is what keeps reconciliation sane. Through the Flux QuickBooks integration, transactions sync into the books automatically, so cards, ACH, and stablecoins are accounted for in the same place. Adding stablecoins acceptance does not add a reconciliation project; it is just another transaction type in the same system.

Getting started without lock-in

Because it is one platform, adding a rail is a configuration decision rather than a new vendor relationship. A business can start with cards and ACH and add stablecoins when it makes sense, or offer all three from the beginning, without renegotiating anything.

Flux pricing is a flat 2.9 percent plus 30 cents per transaction, with volume-based custom pricing as you scale, and no setup fees, monthly fees, minimums, or contracts. That means you can offer more payment options without committing to a standing cost for the privilege.
