# Instant payouts: same-day ACH vs RTP vs FedNow vs push-to-card

"Instant payout" isn't a feature — it's a label sitting on one of four US payment rails, and **which rail you're actually on decides your cost, your cut-off times, your weekends, and whether the money can ever come back.** Two of the four aren't instant at all.

The gap between label and rail is not academic. In a discussion on Reddit's r/fintech, a shift worker described his "instant" pay: he finishes at 3pm on a Friday and waits until Monday, because instant turned out to be same-day ACH with a 2pm cut-off.

Here's the honest map.

## Same-day [ACH](/glossary/ach/) — fast-ish, cheap, asleep on weekends

Frequently sold as instant; it isn't. Same-day ACH is **batch processing**: payments clear in windows with hard cut-offs, on business days only. Miss the last window Friday and the money lands Monday. Its strengths are real — it's cheap and it reaches effectively every US bank account — which is why it's the workhorse. Just don't put the word "instant" anywhere near it.

## Push-to-card (Visa Direct, Mastercard Send) — minutes, 24/7, priced like a card

Push-to-card lands on the recipient's **debit card** in minutes, around the clock, weekends included. Reach is its superpower: most people can't recite their bank account number, but everyone has their debit card. The catch is cost — it's priced like card network traffic, so at high volumes the fees are a real line item. For gig platforms paying workers who want money *tonight*, it's often worth every basis point.

(If you're writing this into a vendor contract, the phrase you want is "push-to-card disbursements" via Visa Direct or Mastercard Send — knowing the term is half the negotiation.)

## RTP — genuinely instant, big-bank coverage

The Clearing House's RTP network settles in **seconds, 24/7/365**, with a per-transaction limit now at $10M. This is the real thing: money moves and is *done*. Coverage is the constraint — it works only if the receiving bank participates, and participation skews toward larger banks.

## FedNow — genuinely instant, the other half of the map

The Federal Reserve's real-time network: also 24/7/365, also now a $10M cap, with coverage skewing toward smaller and regional banks. Between RTP and FedNow the US finally has real instant rails — but neither covers everyone, and plenty of banks are still on neither.

## The two questions that actually matter

**1. What's the fallback?** Real-time rails only work if the receiving bank is reachable. When it isn't, your "instant" payout quietly downgrades — usually to ACH — and your recipient finds out by not getting paid. Any provider promising instant across the board should answer, precisely: *what happens when you can't reach the bank, and who gets told?*

**2. Instant means irrevocable.** RTP and FedNow don't claw back. That's wonderful for recipients and dangerous for you: if your risk checks run *after* the money moves, there is no after. Fast payouts and loose controls are a bad pairing — approvals belong before the rail, not behind it.

Picking the rail is the first decision, not the last. Three that come straight after:
**what happens when the fast rail fails** —
[ask your provider what its fallback rail is](/blog/instant-payout-fallback-rail/) before you buy
instant; **what you give up on fraud** — an
[instant payment is irrevocable](/blog/instant-means-irrevocable/), so the controls have to run
before the send, not after; and **push-to-card specifically**, which behaves less like a payout and
more like a card transaction — [what push-to-card actually is](/blog/what-is-push-to-card/).

UK readers: the map above is US rails. The equivalent decision there is
[Faster Payments vs BACS vs CHAPS](/blog/faster-payments-vs-bacs-vs-chaps/).

## How Fynex does payouts

Fynex treats the rail as a routing decision, not a marketing word. Each [payout](/features/payouts/) is sent over the best rail that can actually reach the recipient — real-time where their bank supports it, push-to-card where the debit card is the fastest path, ACH where cost beats minutes — with the fallback explicit, the approval **before** the money moves, and the recipient told exactly [when it lands](https://docs.fynex.ai/payments-api/v1/docs#tag/payouts).

For [a marketplace or gig platform](/marketplaces/), that's the difference between "we offer instant payouts" on the pricing page and workers who actually stop asking where their money is. Run your business, not your books — and never sell a Friday-afternoon payout that lands on Monday.
