ACH vs wire transfer
ACH and wire transfers are both electronic bank payments, but they behave very differently. In short: ACH is batched, low-cost, and best for routine high-volume payments; a wire is processed individually, settles fast, and is best for urgent or high-value transfers.
The quick answer
Choose ACH when cost and volume matter and a one-to-two-day wait is fine — payroll, contractor runs, recurring bills. Choose a wire when speed and certainty matter and the amount is large — a property closing, a supplier deposit, an urgent settlement.
How ACH works
The Automated Clearing House is a US network that moves bank-to-bank payments in scheduled batches rather than one at a time. Standard ACH clears in one to two business days, while Same Day ACH can settle the same business day for eligible transactions. Because entries are batched, the cost per payment is very low, and under Nacha rules certain entries can be returned or corrected — unlike wires.
How wire transfers work
A wire transfer is processed individually and settled in near real time. Domestic US wires run over Fedwire or CHIPS; cross-border wires are sent as instructions over the SWIFT network and routed through correspondent banks. Wires typically settle the same day (domestic) and are generally irrevocable once sent, which is why they suit high-value, time-critical payments — and why mistakes are hard to undo.
Side by side
| ACH | Wire transfer | |
|---|---|---|
| Processing | Batched | Individual, real-time |
| Geography | US domestic | Domestic and international |
| Speed | 1–2 business days (Same Day ACH available) | Same day (domestic); 1–5 days international |
| Cost | Very low per payment | Higher, often a flat fee plus intermediary charges |
| Reversibility | Reversible in limited cases under Nacha rules | Generally irrevocable |
| Best for | High-volume, routine payments | Urgent or high-value payments |
When to use each
- Use ACH for payroll, contractor and vendor payouts, subscriptions, and any high-volume US disbursement where a short wait is acceptable.
- Use a wire for large, urgent, or cross-border payments where same-day settlement and certainty outweigh the higher cost.
- Use both — many finance teams default to ACH and reserve wires for exceptions.

Frequently asked questions
What is the main difference between ACH and a wire transfer?
ACH is batched, low-cost, and settles in one to two business days, while a wire is processed individually, settles the same day, and is generally irreversible. ACH suits routine high-volume payments; wires suit urgent or high-value ones.
Is ACH cheaper than a wire?
Yes. Because ACH payments are processed in batches, the cost per payment is typically much lower than a wire, which usually carries a flat fee and may add intermediary charges on international transfers.
Is a wire transfer faster than ACH?
Usually. Domestic wires settle the same day, while standard ACH takes one to two business days — though Same Day ACH narrows the gap for eligible transactions.
Can ACH or wire transfers be reversed?
Certain ACH entries can be returned or corrected within defined windows under Nacha rules. Wires are generally irrevocable once sent, so accuracy matters before you send one.
