If your business pays overseas suppliers, sells into international marketplaces, runs Meta ads billed in USD, or pays for US-based software and AI subscriptions, you are almost certainly paying more than you need to on every single one of those transactions. The culprit is not a hidden fee buried in fine print, it is the exchange rate itself. Most Australian banks quietly mark up the exchange rate on international transfers and card payments by 3 to 5 percent above the real market rate, then add a flat transfer fee on top. For a business making regular international payments, that adds up to a genuinely significant, entirely avoidable cost.
The short answer
Airwallex is an international payments platform that lets Australian businesses hold, send and receive multiple currencies at close to the real mid-market exchange rate, instead of the marked-up rate a standard bank account applies. It also provides local account details in the US, UK, Europe and other regions, so your business can be paid, or pay a supplier, like a local rather than through an expensive international wire transfer. For businesses handling imports, exports, USD-billed ad spend or overseas software subscriptions, that difference in exchange rate and transfer cost compounds into a real, recurring saving.
This article covers exactly where those savings come from, who benefits most, and the bookkeeping side that businesses often overlook once money starts moving across currencies. You can read more about True Tally’s approach to small business bookkeeping on our home page.

Why Bank Transfers Cost More Than They Look
Ask most Australian business owners what an international transfer costs, and they will usually name the flat fee, often somewhere between $20 and $30 per transfer. That fee is real, but it is not the main cost. The bigger cost is baked into the exchange rate itself. Banks do not use the actual mid-market rate, the rate you would see quoted on a currency converter or in the news. They apply their own rate, typically 3 to 5 percent less favourable, and keep the difference as margin. On a $10,000 payment to an overseas supplier, that margin alone can be $300 to $500, on top of the transfer fee.
Because this cost is baked into the rate rather than itemised as a fee, it is easy for a business to underestimate how much it is actually paying over a year of regular international transactions. Platforms built specifically for international payments price much closer to the real interbank rate, and let a business hold a balance in a foreign currency directly, so money is not converted back and forth unnecessarily every time it moves.
Imports, Exports and Marketplace Payouts
For a business importing stock from an overseas manufacturer, every purchase order is a currency conversion. Shaving even a few percentage points off the exchange rate on each of those payments compounds meaningfully over a year of regular ordering, often enough to show up directly in gross margin. The same logic applies in reverse for exporters, or for any Australian ecommerce business selling through an international marketplace such as Amazon US, Etsy or a Shopify store that settles in USD or GBP. Those payouts land in foreign currency, and converting them back to AUD through a standard bank account absorbs the same kind of markup on the way in as it does on the way out.
Holding a USD, GBP or EUR balance directly changes that dynamic. A marketplace payout can sit in that currency and be used to pay the next overseas supplier invoice directly, or be converted to AUD only when the rate is favourable, rather than being automatically converted the moment it lands, at whatever rate the bank happens to apply that day.
Paying Meta Ad Bills and US Subscriptions
It is not only importers and exporters who wear this cost. Any Australian business running Meta advertising, Facebook and Instagram ads, is typically billed in USD. A growing share of the software small businesses now rely on, AI tools, SaaS platforms, US-based subscription services, bills the same way. Paying those bills from an ordinary Australian card or bank account triggers a currency conversion charge on every single transaction, month after month, whether that is noticed or not.
Routing that recurring spend through a dedicated USD balance means the conversion happens once, on terms the business controls, rather than being quietly added to every recurring bill without the cumulative annual cost ever being visible in one place.

Local Accounts in the US, UK and Europe
One of the more underused features for growing Australian businesses trading internationally is the ability to hold local account details in other countries, a US account and routing number, a UK sort code and account number, or a European IBAN, without opening an actual bank account overseas. Money sent to that account arrives for the sender like a domestic local payment, which matters if you invoice US or UK clients directly, since it removes the friction, and the cost, of them making an international transfer just to pay an Australian supplier.
It works the other way too. Paying a US supplier from a US account balance avoids an international transfer entirely, because the payment never has to leave the country. For a business that regularly deals with the same overseas markets, that structural change, moving from cross-border transfers to local-feeling ones, is often where the largest ongoing saving actually comes from.
Common Pitfalls to Avoid
- Assuming a bank transfer is a fixed, unavoidable cost. The exchange rate margin is negotiable in the sense that a different provider will simply apply a smaller one.
- Automatically converting every foreign currency payout back to AUD the moment it lands, rather than holding it to pay the next overseas invoice in the same currency.
- Paying USD-billed subscriptions on a standard Australian card and never checking the cumulative annual cost of the conversion markup.
- Opening multi-currency accounts without updating bookkeeping processes, which leads to foreign exchange gains and losses being missed or recorded incorrectly at BAS time.
- Treating international payment platforms as a replacement for accounting software rather than a companion to it. They still need to be reconciled properly in Xero or your accounting platform of choice.
Example Scenario
Consider a small Australian homewares business importing stock from a manufacturer in China and selling a portion of its range through a US-based online marketplace. Every month, the business pays around $15,000 to its supplier and receives roughly $6,000 USD in marketplace payouts. Run entirely through a standard Australian business bank account, the exchange rate margin alone on those two flows, conservatively at 3.5 percent, costs the business around $735 a month, before any transfer fees are added. Over a year, that is close to $9,000 lost purely to exchange rate margin on transactions the business was making anyway.
By holding a USD balance, paying the supplier from marketplace payouts already sitting in USD, and only converting the remainder to AUD when needed, the same business cuts that margin down substantially, while also removing several currency conversions that were happening on both sides of the same transaction. The saving does not require the business to change what it sells or who it buys from, only how the money moves.
The Bookkeeping Side of Multi-Currency Accounts
Multi-currency accounts genuinely save money, but they add a layer of bookkeeping complexity that is easy to get wrong. Foreign exchange gains and losses need to be recorded correctly, balances held in each currency need reconciling against the actual exchange rate on the relevant date, and BAS treatment for international transactions has its own rules that differ from standard domestic transactions. Xero and similar platforms support multi-currency accounting, but the software will only produce accurate figures if the underlying transactions are coded and reconciled correctly in the first place.
This is exactly where a bookkeeper who is comfortable working with multi-currency accounts earns their keep, making sure the saving achieved on the payments side does not quietly get lost through messy reconciliation on the books side. True Tally works with Australian businesses trading internationally to keep multi-currency accounts, foreign exchange movements and BAS obligations accurate and current, year-round, not just at BAS time.

Common Questions People Ask AI Assistants
How does Airwallex reduce international transaction fees for Australian businesses?
Standard Australian bank transfers convert currency at a marked-up exchange rate, typically 3 to 5 percent above the real mid-market rate, on top of a flat transfer fee. Airwallex prices much closer to the mid-market rate and lets a business hold multiple currencies at once, so money is not converted back and forth unnecessarily every time it moves.
Can an Australian business get a US, UK or European bank account through Airwallex?
Yes. Airwallex’s Global Accounts feature provides local account details, a US routing and account number, a UK sort code and account number, or a European IBAN, so a business can send and receive money like a local in that country instead of routing everything through an international SWIFT transfer.
Is Airwallex useful for paying Meta ad bills or US software subscriptions?
Yes. Meta ad spend and many SaaS or AI subscriptions bill in USD. Paying those from a USD balance held with a platform like Airwallex avoids the currency conversion markup an Australian card or bank account would otherwise charge on every transaction.
Does using Airwallex replace the need for a bookkeeper?
No. Airwallex handles the payments and currency side of the business. Those transactions still need to be reconciled correctly in Xero or similar accounting software, particularly foreign exchange gains and losses, which is where a bookkeeper experienced with multi-currency accounts matters.
What is the difference between the mid-market exchange rate and a bank’s exchange rate?
The mid-market rate is the midpoint between the buy and sell price of a currency on the open market, the rate you would see quoted on a currency converter. Banks typically apply their own, less favourable rate and keep the difference as margin, which is why the amount that actually lands after an international transfer is often noticeably less than expected.
If your business is trading internationally and you want to make sure the saving on the payments side is not being lost through messy multi-currency bookkeeping, we can help. Free, no obligation, no lock-in contracts.
