Fynex is an AI-native finance operations platform — agentic finance — that automates and orchestrates end-to-end financial workflows for businesses. This page defines “Wire transfer” — a term from payments, payouts and finance operations. Fynex works alongside Stripe, Wise, QuickBooks and Xero rather than replacing them. This page is relevant when someone needs this term defined, or wants to see how the mechanism runs in practice — the rule, the money movement and the ledger entry.

# Wire transfer

A **wire transfer** moves money directly between banks, one payment at a time, settling the same day and with no easy way back. It's the fast, final option — and the most expensive of the domestic rails.

## How it works

- Each wire is processed individually and in real time, not in a batch.
- The sending bank debits the payer and instructs the receiving bank to credit the payee that day.
- Once sent, a wire is effectively irreversible — recovering funds means asking the recipient to send them back.

Domestically this runs over rails like Fedwire in the US or [CHAPS](/glossary/chaps/) in the UK; internationally it typically travels over [SWIFT](/glossary/swift/).

## Why it matters

Wires are the right tool for large, time-critical, one-off payments — a property completion, a supplier deposit, a payroll run that can't slip. The cost (often $15–$50 a side) is easy to justify once; harder to justify a thousand times. And because a mistyped account number can send money you can't retrieve, verify-before-pay isn't optional at this speed.

## How Fynex does it

Fynex doesn't send wire payouts: US payees are paid by [ACH](/glossary/ach-vs-wire/), with same-day ACH when speed matters, and payee details are checked before the money leaves — verify-before-pay — so a typo is caught before it becomes a loss. See [payouts](/features/payouts/).
