Airwallex Review

A global business account and payment platform with published rates, no lock-in contract and unusually cheap FX. Strong for cross-border sellers; weaker as a plain domestic card processor, and not an option for high-risk merchants.

A business account that also acquires

Airwallex was founded in Melbourne in 2015 by five co-founders and is now dual headquartered in Singapore and San Francisco. As of its June 2026 Series H round it is valued at $11 billion, employs over 2,300 people across 27 offices, and reported $287 billion in annualized transaction volume and $1.3 billion in annualized revenue as of March 2026, serving more than 676,000 businesses directly or through platform customers. It is not a merchant services ISO in the traditional sense: card acquiring is one module on a platform that also covers multi-currency accounts, international transfers, issued cards and expense management.

That framing explains most of its strengths and most of its gaps. It is very good at moving money between currencies and jurisdictions, and largely absent from the parts of the market that revolve around terminals, retail POS and high-risk underwriting.

What it costs

Airwallex publishes its rates, which already separates it from most of the merchant account industry. US pricing is 2.80% + $0.30 for domestic cards and 4.30% + $0.30 for international cards, with local payment methods at $0.30 plus the method's own fee. The Explore plan carries no monthly fee; Grow is $12 per user per month plus a platform fee; Accelerate is custom.

The number that actually differentiates the product is the FX markup: 0.5% above interbank for major currencies and 1% for everything else. A processor charging a 2.5–4% conversion spread will quietly cost a cross-border seller far more than the difference in headline card rates.

Settlement and reserves

Settlements batch daily and land in the Airwallex wallet after the later of the payment method's schedule — often around T+2 business days — and any reserve terms on the account. Once settled, the money is usable immediately for payouts, conversions or card spend, which removes the extra one-to-three-day wait most processors impose before funds reach a bank account.

The counterweight is that Airwallex documents rolling reserves, holding part of each settlement for a defined period such as 90 days, and notes that some accounts carry an additional one-off settlement delay. Neither is disclosed until underwriting, so treat your reserve terms as a question to ask, not an assumption.

Where it does not fit

• Domestic-only US merchants, who can beat 2.80% + $0.30 elsewhere
• Retail and hospitality needing terminals, POS software and card-present rates
• High-risk verticals, which need a specialist underwriter
• Businesses that want a named account manager — support responsiveness is the most common complaint in public reviews
