Cross-border online payments: How businesses can reduce international transaction costs

As global supply chains become increasingly dispersed and eCommerce expands across multiple markets, many SMEs, online retailers, and export-oriented companies in Hong Kong routinely deal with international payments. Whether settling deposits with overseas suppliers, paying for advertising services, or compensating foreign partners, the efficiency and cost structure of cross-border payments can have a direct impact on business profitability.

Many companies initially rely on traditional bank wire transfers for international transactions. However, as the number of payments grows and the range of currencies and regions expands, conventional methods often become inadequate. Bank transfers can be slow, exchange rate mark-ups are opaque, fee allocation rules are complex, and fund arrival times are unpredictable. These issues can reduce supply chain efficiency and limit a business’s control over cash flow. This article explores how modern payment infrastructure enables companies to manage international payments more efficiently.

How online payments differ from traditional bank transfers

Online payments allow businesses to initiate and manage cross-border transfers through digital platforms. Companies can set up payee details online, view real-time exchange rates, submit payment instructions, and track the progress of each transfer. Depending on the platform, payment records may also be automatically synced with accounting systems. The benefits go beyond “online convenience” – streamlined workflows and greater visibility into transactions are key advantages.

Unlike traditional cross-border wire transfers that rely on the SWIFT network, modern online platforms often prioritise local payment networks. Traditional transfers frequently involve multiple intermediary banks, which can take several business days to clear and may incur additional fees. This makes it difficult for companies to accurately predict when funds will arrive and the exact amount received.

By using local networks to shorten transit times, businesses gain better control over cash flow. Online platforms often provide real-time exchange rates and fee breakdowns before payment submission, enabling companies to anticipate costs and avoid hidden charges. Integration with accounting systems further automates record-keeping and reduces manual reconciliation.

The difference between online payments and traditional transfers extends beyond the interface – it affects the money’s journey, the transparency of fees, and overall workflow efficiency. For SMEs, eCommerce operators, and exporters, these differences can have a greater long-term impact on costs and operational efficiency than simply comparing nominal transaction fees.

3 key challenges in international business payments

Hidden costs of traditional transfers

When evaluating cross-border payment options, companies often focus on visible fees. However, costs can also include intermediary bank charges, receiving bank fees, and less obvious exchange rate mark-ups. Banks may apply a margin above the interbank rate to generate profit, which is rarely transparent and can exceed the standard transaction fee in large transfers.

When considering an online solution, businesses should focus on total cost rather than a single fee. Comparing actual exchange costs, funds received, and labour involved provides a clearer picture of long-term impact.

Uncertain arrival times of funds

Traditional bank transfers can take anywhere from one to five business days, depending on the number of intermediary banks and time zone differences. Delays may also occur due to holidays or incorrect payment information, which can disrupt supplier payments, production schedules, or shipment timelines.

By contrast, online payment platforms that prioritise local networks enable faster and more predictable transfers. Real-time tracking allows businesses to monitor fund status and reduces the need for repeated follow-ups with recipients, helping to plan cash flow and inventory more accurately.

Complex processes increase administrative burden

As companies expand internationally, managing multiple bank accounts and currencies can become cumbersome. Payment information may need to be entered across several systems, with reconciliation largely manual. As transaction volumes grow, finance teams spend more time verifying data and tracking payments, increasing operational costs.

A unified platform can integrate collections, currency conversion, and payments while syncing with accounting systems. This reduces duplication, minimises errors, and allows management to gain better oversight of cash flows, supporting more informed decisions.

Choosing the right online payment solution for your business

When evaluating online payment providers, businesses should consider both transaction fees and overall cost structures. Exchange rate transparency and closeness to market rates often have a bigger impact than nominal service fees. Platforms that obscure rate mark-ups or hidden charges can result in higher overall costs even if the stated fee seems low.

Companies should also assess intermediary bank charges and the reliability of fund arrival times, as multi-bank transfers can introduce uncertainty that affects supply chains and cash flow.

As businesses expand internationally, multi-currency management and system integration become increasingly important. Platforms that consolidate funds across currencies, integrate with accounting systems, and support automation or batch payments can significantly reduce manual processing and reconciliation, lowering operational overhead.

Common cross-border payment challenges and how online platforms address them

Selecting an online payment solution should therefore balance fee transparency, reliability, compliance, and platform integration. Estimating monthly payment volumes, comparing exchange rates, and factoring in transfer times and automation capabilities helps identify a solution that is both secure and operationally efficient.

How modern platforms redesign cross-border payments

Platforms like Airwallex don’t just move traditional transfers online – they rethink how funds flow between countries. By integrating global collection, local clearing, and foreign exchange management in a single platform, businesses avoid multiple intermediaries and fragmented systems.

Local-first payments streamline cross-border transfers, making them simpler, faster, and more predictable. Companies can manage payments as part of daily operations without navigating complex workflows.

Global payment network

Airwallex connects with local payment networks in over 120 countries, supplementing SWIFT where necessary. This local-first approach ensures transparency, reduces duplicate fees, and accelerates fund arrival – around 93% of payments are same-day, with 50% near-instant. Smart routing and status notifications minimise reconciliation effort.

Local-like collections across borders

Global accounts allow businesses to quickly open local accounts in multiple regions (e.g., US dollar ACH accounts), while managing multiple currencies. Payments to overseas suppliers can use the same currency directly, avoiding double conversion costs. Real-world cases, such as Dalstrong, show annual savings of roughly US$40,000 by reusing collected foreign currency instead of converting twice.

Unified FX, payments, and expense management

By consolidating collections, FX, payments, company cards, and expense management on one platform, businesses improve efficiency and control. Transactions are recorded consistently, invoices sync automatically, and risk management features like card limits, merchant category controls, and multi-level approvals are built into the workflow. Clients like Bilue report around 20% savings in accounting overhead, while Bowtie achieves 3–5% savings on foreign payments and real-time visibility on expense control through virtual cards.

Frequently asked questions

What is the difference between a transfer and a remittance?

Transfers generally occur within the same region and currency (e.g., Hong Kong’s Faster Payment System), with near-instant settlement and low fees. Remittances often involve cross-border or multi-currency payments, requiring FX conversion and clearing, and typically take longer and cost more.

Can local payment systems like FPS provide instant settlement?

FPS is nearly instant for local HKD or RMB transactions, but does not support cross-border or other currencies. International payments still require an online payment platform.

Can I make international payments via a mobile app?

Yes. Airwallex’s app allows instant cross-border payments, real-time multi-currency balances, and integration with eCommerce platforms or APIs, improving efficiency.
