If you are a global entrepreneur, freelancer, or NRI managing a US bank account, you will inevitably need to transfer money across borders. Two of the most common terms you will encounter are SWIFT and ACH. But what do they mean, and which one should you use to save money on fees?

Understanding the Basics
What is SWIFT?
The Society for Worldwide Interbank Financial Telecommunication (SWIFT) is a massive messaging network banks use to securely send and receive information, such as money transfer instructions. It is the standard for international wires.
What is ACH?
The Automated Clearing House (ACH) is an electronic network for financial transactions primarily within the United States. It processes large volumes of credit and debit transactions in batches.

Pros & Cons
SWIFT Transfers
- Pros: Unmatched global reach; highly secure; can handle extremely large transfer amounts.
- Cons: Expensive; can be delayed by intermediary banks; exchange rates are often marked up by traditional banks.
ACH Transfers
- Pros: Extremely cost-effective (often free); highly reliable for setting up automated monthly bills or payroll.
- Cons: Limited international reach; transfers are processed in batches so they are rarely instant.
Storage Instructions for Transfer Records
Always download and store the MT103 document (the official routing receipt for a SWIFT transfer) in a secure, encrypted digital folder. If your international transfer is ever delayed, this document is the exact “tracking number” your receiving bank needs to locate the funds.
FAQs
Q: Can I send an ACH transfer to an Indian bank account?
A: Traditional ACH is strictly for US banks. However, “Global ACH” services are emerging, though it is usually easier to use third-party remittance services for US-to-India transfers.
Q: What is a routing number, and is it the same as a SWIFT code?
A: No. A routing number is a 9-digit code used strictly for domestic ACH and wire transfers within the US. A SWIFT code (or BIC) is an 8-to-11-character code used to identify specific banks worldwide for international transfers.
Q: Why did my SWIFT transfer arrive with less money than I sent?
A: SWIFT transfers often pass through “intermediary” or correspondent banks along the way. These banks take a small handling fee (usually $10 to $20) directly from the transfer amount before it reaches your final destination.
