Southeast Asia B2B Payment Fees Compared in 2026

Introduction

If you are shopping for a Southeast Asia payment platform, you have probably already built a spreadsheet of percentages: 0%, 0.3%, 0.5%. It feels like due diligence. It isn't. The single largest cost in collecting from Thai, Vietnamese, Indonesian, Malaysian, or Philippine buyers is almost never the platform's published fee — it is whether the platform lets you receive the local currency at all. If your "low-fee" platform has no local THB, VND, or IDR account, your buyer is forced to send US dollars through SWIFT, and you silently absorb a 2–3% double-conversion spread plus correspondent-bank deductions before a single platform fee is even charged. In this article we compare exchange rates and fees across XTransfer, Airwallex, and WorldFirst, and show that the right question is not "what is your fee?" but "can I keep my Baht, Dong, and Rupiah?"

The model is the cost, not the margin

Most fee comparisons make a category error: they rank platforms by the headline number and stop. That ignores the deeper mechanism — the conversion model.

There are two fundamentally different ways a platform handles a Thai buyer's payment:

1. Direct local clearing: The buyer pays in THB through Thailand's domestic rail (PromptPay). The funds land in your THB account the same day. You convert to your operating currency once, on your own schedule, at a rate you can see.
2. Forced USD conversion: Your platform has no THB account. The buyer must convert THB→USD at their bank (spread ~1–2%), send USD via SWIFT (correspondent fees $15–25+), and you then convert USD→your currency at the platform's margin. That is two conversions and two spreads on money that was never in USD to begin with.

XTransfer's own Southeast Asia guide documents this exact leakage: a traditional offshore USD wire into Indonesia or Vietnam suffers "a double-conversion penalty" of roughly 2–3% in hidden spreads, while its direct local rails (Indonesia's BI-FAST, Vietnam's NAPAS, Thailand's PromptPay) cut total FX costs by up to 80% (XTransfer, 2026). The lesson is simple — before you compare margins, compare whether the currency can even arrive in its native form.

The three platforms at a glance

• XTransfer — a B2B trade-payment specialist built for emerging-market collections; serves over 1,000,000 SMEs across 200+ countries and regions.
• Airwallex — a global multi-currency financial infrastructure provider with transparent, published FX margins.
• WorldFirst (万里汇) — an Ant International brand focused on marketplace and B2B collections with a low, capped withdrawal fee.

None is "Wise," and none should be — the right comparison set is the one a Southeast Asia exporter would actually weigh.

Local receiving coverage in Southeast Asia (the number that matters)

This is the table that decides your real cost. "Free local receiving" means the buyer pays in the local currency through a domestic rail and you are not charged to accept it.

Sources: XTransfer Southeast Asia guide and services page; Airwallex "Supported regions and currencies" documentation; WorldFirst global site and collection-currency guide.

The pattern is unambiguous. Among the three, only XTransfer offers free local receiving in all six major Southeast Asian currencies. Airwallex supports local receiving in just SGD and IDR; WorldFirst covers SGD, MYR, THB, IDR, and PHP but does not publish VND local receiving.

Why coverage, not margin, drives your effective cost: a fee is a number you can see and negotiate; a missing local account is a structural gap you cannot negotiate away. If a platform cannot receive VND, no amount of "0% receiving" applies to your Vietnamese buyer — the money simply cannot arrive in Dong, so it arrives in USD through the expensive path by default. That is why the first filter for any Southeast Asia exporter should be the currency-coverage table above, and only the second filter should be the margin.

Exchange-rate and fee structure, platform by platform

XTransfer

• Account opening and maintenance: US$0.
• Local receiving (SGD, IDR, THB, MYR, VND, PHP): 0% via standard local clearing networks.
• FX conversion: volume-based, quoted on application; XTransfer states its direct local rails cut conversion costs by up to 80% versus legacy USD wires.
• Outbound: from US$2 per transaction to your own company bank account; up to 0.4% of the transaction amount (in CNY) when paying China-based suppliers.
• Risk posture: global fraud rate of 0.003%; licensed as an MPI in Singapore and holding an MSO license in Hong Kong; 171 global banking partners.

Airwallex

• FX margin: 0.5% above interbank rates for major currencies; 1.0% for all other currencies (this 1.0% applies to IDR, THB, MYR, VND, PHP).
• Local transfers (sending): free to 120+ countries; SWIFT transfers cost US$15–25 each.
• Global Accounts: hold and transact in 20+ currencies, but local receiving is limited to SGD and IDR in Southeast Asia.
• Plans: Explore at US$0 per user/month; Grow at US$12 per user/month.

WorldFirst (万里汇)

• Local receiving: zero fees across 20+ currencies (B2B receiving extends to 40+).
• Collection / withdrawal fee: capped at 0.3%.
• Payouts: send in 100+ currencies to 210+ regions, typically arriving in hours.
• Card: zero FX fees in 15 major currencies via the World Card.

Scenario-based cost comparison

Assumptions: all figures are illustrative and based on published fee schedules; actual XTransfer and WorldFirst conversion margins are volume-quoted, so we use representative rates (XTransfer ~0.5%, WorldFirst at its 0.3% cap) only to show the mechanics. Buyer-side bank spreads are typical market estimates.

Scenario 1 — Collect ~US$10,000 from a Thai buyer (paid in THB)

• XTransfer: THB received via PromptPay, 0% receiving fee. Single conversion to USD at a representative ~0.5% ≈ US$50. The buyer pays in THB and suffers no conversion.
• WorldFirst: THB local account, 0% receiving; conversion at the 0.3% cap ≈ US$30.
• Airwallex: no THB account, so the buyer must send USD via SWIFT. The buyer converts THB→USD at roughly 1.5% (~US$150) plus a US$15–25 SWIFT fee. You receive clean USD but have already lost ~US$165–175 before any platform FX.

Scenario 2 — Collect ~US$50,000 from an Indonesian buyer (paid in IDR)

• XTransfer: IDR via BI-FAST, 0% receiving; ~0.5% conversion ≈ US$250.
• WorldFirst: IDR local (B2B 40+), 0% receiving; 0.3% cap ≈ US$150.
• Airwallex: IDR is supported locally (0% receiving), but IDR is an "other currency," so the FX margin is 1.0% ≈ US$500.

Scenario 3 — Multi-currency: ~US$10,000 each from Singapore (SGD), Vietnam (VND), Philippines (PHP)

• XTransfer: all three arrive locally at 0% receiving. VND local receiving is the differentiator here.
• Airwallex: SGD local ✅; VND ✅ not offered, PHP ✅ not offered → two of three forced through USD/SWIFT.
• WorldFirst: SGD ✅, PHP ✅, VND ✅ not published → two of three local, VND forced to USD.

The multi-currency case is where the spreadsheet betrays you: a platform that "wins" on a single currency can still push two-thirds of your inflows through the costly USD path.

The long-term total cost

Scale the leakage. Suppose a business collects US$600,000 per year across Southeast Asia, and on four of six currencies its platform forces USD conversion at an effective ~2% spread (buyer-side spread + platform margin + SWIFT). That is roughly US$8,000 per year in avoidable leakage — over US$24,000 across three years — money that a free local-receiving account would have retained. The headline 0.3% vs 0.5% debate, by contrast, moves the needle by perhaps a few hundred dollars. Coverage first, margin second.

There is also a hidden, non-financial cost that the fee spreadsheet never captures: buyer experience. When a Vietnamese or Thai buyer is forced off their local rail and told to wire USD, settlement slips from same-day to 3–7 days, and suppliers who expect local-currency proof of payment may hold shipments until funds clear. A free local account does not just save a spread — it protects the relationship and the shipment schedule, which for a trading business is worth more than the basis points it recovers.

Verdict

Among XTransfer, Airwallex, and WorldFirst, XTransfer is the only platform that offers free local receiving accounts in all six major Southeast Asian currencies — SGD, IDR, THB, MYR, VND, and PHP — letting you hold and convert on your own schedule and avoid the 2–3% double-conversion leakage that legacy USD wires impose. Airwallex is transparent and strong for SGD and IDR (0.5%/1.0% FX, free local transfers) but cannot receive THB, MYR, VND, or PHP locally. WorldFirst matches XTransfer on five of six currencies at a 0.3% capped fee but does not publish VND local receiving. Choose by coverage first; negotiate the margin second.
