Cross-border payment volumes have grown into the hundreds of trillions annually, with B2B transactions making up the bulk of that total, and platform operators and finance teams are under growing pressure to move money across borders quickly and cost-effectively. An international ACH transfer is one way for platforms and companies to send mass payouts globally, and it’s commonly used to disburse funds to contractors, gig workers, sellers, and other payees abroad.
In this blog post, we’ll cover what international ACH transfers are, how to send an international ACH payment, the benefits and trade-offs of this method compared to other solutions and more.
TLDR:
- International ACH sends funds directly to payee bank accounts in 1-5 business days at fees typically ranging from $0-$3.
- Wire transfers cost up to $50 per transaction; ACH is the lower-cost choice for recurring mass payouts to gig workers and sellers.
- U.S.-originating international ACH payments require IAT classification and Nacha compliance in addition to the receiving country’s rules.
- ACH settles slower than wires and is not accepted in every country, so verify your payee corridors before committing to this rail.
- Routable is a payout orchestration platform that routes international disbursements across 220+ countries in 140+ currencies via CSV or API.
What Is International ACH?
International ACH transfers (sometimes referred to as global ACH) give platforms and businesses a way to pay their creators, gig workers, sellers, and contractors around the world via ACH payments.
If you’ve ever set up autopay for your cell phone bill or you’ve been paid via direct deposit, you’ve used the Automated Clearing House (ACH). ACH is an electronic network that moves money between bank accounts. While many ACH transfers happen domestically, international ACH is used when payments need to be made between companies or individuals in different countries. For a closer look at how ACH works in a purely domestic context, see our guide to business-to-business ACH.
International ACH payments are made directly to a recipient’s bank account through a clearing system, which varies depending on the country. There’s no one globally accepted ACH system. In the United States, the system is the National Automated Clearing House Association (Nacha), while in Europe, for example, euro-denominated transfers are typically routed through the Single Euro Payments Area (SEPA) framework.
Transfers from the U.S. are required to follow all Nacha rules, including providing necessary identifying information for each party in the transaction and having gateway operators classify any payments to and from financial institutions outside the country.
Domestic ACH vs. International ACH: What’s the Difference?
There are at least three differences to consider between domestic ACH and international ACH:
How International ACH Payments Work in Practice
Few traditional banks offer international ACH payouts, but a payout orchestration platform like Routable is purpose-built for exactly this use case. Routable functions as an orchestration layer that sits above multiple processors and rails, routing each disbursement through the optimal path for that payee corridor and automatically rerouting to a backup rail when the primary route fails. That architecture matters when you’re running cross-border payouts to contractors, sellers, or gig workers across dozens of countries at once: a single failed processor does not stall your entire batch. Routable covers 220+ countries and territories in 140+ currencies, and delivers 30-50% savings on foreign exchange rates compared to bank alternatives, making it a cost-effective choice for platforms running recurring cross-border disbursements at volume.
While regulatory requirements for international ACH transfers tend to be complex, payout orchestration platforms eliminate much of this bureaucracy for your team by providing a secure environment for transfers and covering all necessary country-specific requirements.
Payout orchestration platforms also tend to be more cost-effective than routing payments through your bank, a meaningful advantage when mass payouts make fees compound quickly. For a broader look at how these rails fit into a global payment strategy, see our guide to cross-border payments. International ACH disbursements are also much simpler to manage when using a payout orchestration platform, giving teams a centralized view of all payments, both domestic and cross-border.
If you would like to process the payment with your bank, it’s pretty straightforward (if they offer the service). Here’s how it would generally work.
How to Make an International ACH Payment With Your Bank
- Check that your bank offers international ACH payments.
- Have your payee’s details ready. You’ll need their:
- Name and address
- Bank account number and routing number
- Complete the payment via your bank’s online portal, over the phone or in person.
- Confirm the cost, including fees and the currency exchange rate
How Long Does International ACH Transfer Take?
International ACH transfers can take between one to five business days to clear, with most taking around three days.
This is due to security and regulations, as well as the fact that most banks process ACH transfers in batches. Even after approving the transfer, the receiving bank may take a bit of time to deposit the money into the recipient’s account.
These transfers are almost always very low cost (under three dollars) or even free in some cases.
International ACH Transfer vs. International ACH Transaction (IAT)
An international ACH transfer differs from an international ACH transaction (IAT) in one key way:
- International ACH transfer refers to the movement of money from one place to another across country borders.
- IAT, on the other hand, is the SEC code used for those types of transfers.
All international ACH payments that originate from or come into the United States must have IAT reports submitted to Nacha (the United States’s clearing house for ACH transfers) to make sure that the payments are in line with all legal requirements.
International ACH vs. Wire Transfers: Key Differences
Both international ACH transfers and wire transfers allow platforms and businesses to move funds between accounts at different banks, but they accomplish that goal in different ways. For a closer look at the wire side of that equation, see our guide to cross-border wire transfers. Here are a few key differences between the two rails:
- Transfer networks: While ACH transfers use the Automated Clearing House network, wire transfers use different networks (usually the SWIFT or Fedwire networks) to transfer money.
- Speed: ACH transfers are usually slower to process than wires, since banks batch-process these payments. This is particularly true for international ACH transfers, which can take up to five days to go through.
- Cost: ACH transfers are much more cost-effective than wire transfers. International wire transfers can cost up to $50 per transaction, which adds up quickly. For this reason, ACH transfers are a better choice for regular or multiple payments while wire transfers make more sense for one-time, time-sensitive payments.
- Security: Both ACH and wire transfers are generally secure. However, it’s important to be aware of and take precautions against wire transfer fraud. In these schemes, scammers pose as a trusted contact (like a vendor, business or family member) and request a wire transfer for a seemingly legitimate reason, then steal the money that is sent.
Benefits and Trade-Offs of International ACH for Your Business
For a long time, the main drawback of international ACH transfers was the fact that few banks offered this payment option. Now that payout orchestration platforms have made international ACH a viable choice, it’s worth weighing the benefits and trade-offs of this payment method.
Benefits of International ACH Payments
- Low cost: ACH transfers are an inexpensive way to transfer money across borders. International ACH fees usually range from $0 – $3.
- Secure: ACH transfers happen over a secure network and are carefully governed by both the originating and receiving country, which provides peace of mind when transferring large sums.
- Mass payouts: Low-cost ACH transfers are a good option for sending mass payouts to creators, gig workers, sellers, or contractors at once.
- Money goes directly into the payee’s bank account. Unlike some other digital payment methods, international ACH is a direct-to-bank transfer, meaning the money doesn’t get stuck in a third-party holding account. Your payee has access to their funds more quickly.
Trade-Offs of International ACH Payments
- Slower: International ACH transfers are typically slower than wire transfers (though likely still faster than mailing a physical check).
- Not accepted by all countries: While many countries accept ACH transfers, there are still some that do not.
Sending International ACH Payments with Routable
Running international ACH at scale creates compounding operational load: payee onboarding across dozens of corridors, bank account validation, rail selection, compliance checks, and year-end tax documentation for a mixed domestic and international payee population. Routable is a payout orchestration platform built for this full workflow. It sits above multiple processors and rails, selecting the right path for each payee corridor and rerouting automatically when the primary fails. Coverage spans 220+ countries and territories in 140+ currencies at 30-50% savings on foreign exchange rates compared to bank alternatives. Getting started takes two steps, whether your team runs payouts through a CSV upload or a developer-friendly API.
1. Create Your Payees in the Routable Dashboard
Add each payee through the dashboard or API. During onboarding, Routable’s white-label interface prompts each payee to submit their bank account details and the appropriate tax forms: W-8 for international payees, W-9 for domestic. TIN validation runs automatically against IRS records. Each payee is then screened against 6,000+ sanctions and watchlists before any funds move. Once a payee is in the system, you do not re-collect their details on subsequent payment runs. Routable retains the profile and routes every new disbursement through the same validated payee record.
2. Upload Your File or Trigger a Payout via API
With payees onboarded, your team can send hundreds of thousands of disbursements to contractors, gig workers, sellers, and creators through a single dashboard or API call.
Beyond international ACH, Routable’s payout orchestration platform handles hundreds of thousands of disbursements, paying contractors, gig workers, sellers, and creators across borders through a single dashboard or API call. Domestically, Routable supports ACH across four speed tiers (Standard, Expedited, Next Day, and Same Day), wire transfers, and push-to-card, plus instant payments via RTP and FedNow for payees who need same-day or real-time settlement. Internationally, Routable blends local rails with SWIFT to route each disbursement through the optimal path for that payee’s corridor. The orchestration layer selects the right rail for each corridor automatically and reroutes to a backup if the primary path fails, so a single processor outage does not stall your entire batch.
At year-end, Routable generates 1042-S forms for foreign payees and 1099-NEC forms for domestic payees, identifying the correct form based on the W-8 and W-9 data collected at onboarding. For teams running payouts inside NetSuite, Sage Intacct, QuickBooks, or Xero, Routable syncs payment data bi-directionally in real time, keeping your general ledger current without a manual reconciliation step at month end.
FAQ
What’s the difference between international ACH and an international wire transfer for paying gig workers and contractors abroad?
International ACH deposits funds directly into your payee’s bank account in 1-5 business days at fees typically ranging from $0-$3 per transaction, while international wire transfers use the SWIFT network and can cost up to $50 per transaction. For platforms running recurring mass payouts to contractors, sellers, or gig workers across multiple countries, ACH is the lower-cost rail. Wires make more sense for one-time, time-sensitive, high-value transfers where speed outweighs cost.
Can I send international ACH payments to all countries through a payout orchestration platform?
Not every country accepts ACH-style transfers, so verifying your specific payee corridors before committing to this rail is a hard requirement. A payout orchestration platform like Routable routes disbursements across 220+ countries and 140+ currencies, automatically selecting the optimal local rail for each corridor and rerouting to a backup path when the primary route fails, so a single unsupported corridor does not stall your entire batch.
What is the IAT classification requirement for international ACH payments originating from the U.S.?
Any ACH payment that originates from or flows into the United States must carry an IAT (International ACH Transaction) SEC code and comply with Nacha reporting rules, in addition to the receiving country’s clearing system requirements. Payout orchestration platforms handle this classification automatically, so your team is not manually managing per-transaction regulatory coding across dozens of payee corridors.
International ACH vs. wire transfer: which rail makes sense for a marketplace running mass payouts to international sellers?
International ACH is the right default rail for recurring, high-volume disbursements to sellers and contractors abroad. Fees in the $0-$3 range scale far better than wire fees up to $50 per transaction when you are processing hundreds or thousands of payouts per cycle. Reserve wire transfers for one-off, time-sensitive payments where the 1-5 business day ACH settlement window creates an unacceptable delay for the payee.
How does Routable handle year-end tax compliance for international payees receiving international ACH disbursements?
Routable collects W-8 and W-9 forms during payee onboarding through a white-label interface, then uses that data at year-end to generate 1042-S forms for foreign payees and 1099-NEC forms for domestic payees, automatically identifying which form applies to each payee without manual sorting. This removes the compliance bottleneck that typically hits platforms managing mixed domestic and international payee populations at filing season.
