Pay.net vs Airwallex: Multi-Rail Routing vs Global Multi-Currency Ops

Two Different Layers of the Payments Stack

Airwallex is a global financial operating system for businesses that operate across borders. Its core product is a multi-currency business account: hold balances in 20+ currencies, issue local receiving accounts (IBANs, US ABA/routing numbers, UK sort codes) in 60+ countries, convert FX at interbank-adjacent rates, and issue corporate cards — all from one dashboard and API.

Pay.net is a merchant payment gateway with AI-powered multi-rail routing. It doesn't hold your balances or issue local receiving accounts — it routes every incoming or outgoing transaction to the cheapest, fastest, safest rail available (FedNow, RTP, ACH, SEPA Instant, SWIFT, PIX, UPI, card, or stablecoin), with Fraud.net intelligence informing every routing decision.

These are genuinely different layers of the stack. Airwallex answers "where do I hold and move money globally, in what currencies, with what FX cost?" Pay.net answers "what is the optimal payment rail for this specific transaction, right now?" Many businesses need both — Airwallex for treasury/FX operations, Pay.net for payment acceptance and settlement optimization.

Feature Comparison at a Glance

What Airwallex Actually Offers

Airwallex's core product is the global business account: a single dashboard that lets a company hold balances in 20+ currencies, receive payments via local account details in 60+ countries (as if it had a local bank presence in each), convert between currencies at rates close to the interbank mid-market rate, and issue corporate cards for team spend — all accessible via API for platforms that want to embed these capabilities.

This is purpose-built for businesses with genuinely global operations: a US company invoicing European customers in EUR, receiving GBP from UK clients, and paying APAC contractors in local currency — without opening a dozen local bank accounts or losing margin to repeated currency conversion. For platforms and marketplaces, Airwallex's embedded finance APIs let them offer multi-currency accounts to their own customers.

Airwallex is particularly strong for treasury operations, e-commerce sellers managing multi-marketplace payouts (Amazon, eBay, Shopify across regions), and platforms building embedded financial products for their own merchant base.

Where Airwallex Leads

Multi-Currency Balance Holding

Pay.net does not hold balances in multiple currencies — it routes transactions to the optimal rail and settles. Airwallex's ability to hold 20+ currencies natively and convert only when needed (rather than converting on every inbound/outbound transaction) is a structural treasury advantage for businesses with recurring multi-currency cash flows.

Local Receiving Accounts in 60+ Countries

A business can receive a EUR wire as if it had a Frankfurt bank account, a GBP payment as if it had a London account, and a USD ACH as if it had a US account — all without opening a single local bank relationship. Pay.net doesn't offer this; it's a fundamentally different product category (banking-as-a-service style infrastructure vs. payment gateway routing).

FX Rate Quality

Airwallex's core differentiator against traditional banks and most payment gateways is FX conversion priced close to interbank mid-market rates rather than the 2-4% spreads typical of legacy banking. For businesses with high multi-currency conversion volume, this compounds into material savings that neither Pay.net nor most card-first processors are architected to compete on directly.

Corporate Card & Spend Management

Airwallex issues physical and virtual corporate cards with built-in spend controls and expense management — a business operations layer entirely outside Pay.net's scope as a merchant payment gateway.

Where Pay.net Leads

FedNow Native Settlement

This is the sharpest differentiator. Airwallex does not support FedNow or RTP. Pay.net's native FedNow integration settles inbound and outbound US payments in under 5 seconds, 24/7/365 — a capability entirely outside Airwallex's product scope as a multi-currency account provider rather than a payment rail router.

Stablecoin Settlement for Large Cross-Border B2B

For a $1M+ cross-border B2B payment, Pay.net can route through stablecoin settlement at 0.3% — settling in hours with no correspondent banking chain. Airwallex's multi-currency accounts reduce FX friction but still ultimately settle through traditional banking rails for large transfers; it has no stablecoin settlement rail.

AI-Powered Per-Transaction Rail Routing

Airwallex optimizes FX conversion and account routing but does not perform real-time, per-transaction rail selection across FedNow/RTP/ACH/SEPA/SWIFT/stablecoin/card the way Pay.net's routing engine does. For merchants accepting payments (as opposed to holding treasury balances), Pay.net's routing engine is solving a different, acceptance-side problem.

Fraud Detection at the Routing Layer

Pay.net's Fraud.net-powered engine applies cross-rail fraud intelligence — built from over a decade of card, ACH, wire, and crypto fraud signal data — as an input to the routing decision itself, with a contractual guarantee of fraud losses below 2 basis points. Airwallex's risk controls are standard payment-industry practice without an equivalent cross-rail intelligence network or loss guarantee.

Published Per-Rail Pricing

Pay.net publishes transparent per-rail rates (2.4% + $0.25 domestic card, 0.6% capped ACH, $0.50 flat FedNow, 0.3% stablecoin). Airwallex publishes FX and card rates but account-level fees and volume pricing often require a sales conversation for enterprise tiers.

The Right Architecture for Global Merchants

For most businesses operating internationally, the optimal setup often isn't either/or:

• Treasury and multi-currency operations (holding balances, paying global contractors, managing FX exposure): Airwallex's multi-currency account and local receiving infrastructure is purpose-built for this
• Payment acceptance with real-time settlement and rail optimization (accepting customer payments, routing to the cheapest/fastest/safest rail per transaction): Pay.net's multi-rail gateway with FedNow and stablecoin settlement is purpose-built for this
• Combined: Many global merchants use Airwallex for treasury/FX and Pay.net for payment acceptance and settlement — they solve adjacent, not competing, problems

• Fraud prevention with a contractual guarantee — <2 basis point fraud loss guarantee backed by cross-rail intelligence

Frequently Asked Questions

Does Airwallex support FedNow or stablecoin settlement?

No. As of 2026, Airwallex does not support FedNow real-time settlement or stablecoin payment rails. Pay.net natively supports both — FedNow settles under 5 seconds, and stablecoin settlement (USDC/USDT) is available at 0.3% for B2B transfers.

Is Pay.net a replacement for Airwallex's multi-currency account?

No — they solve different problems. Airwallex is a multi-currency balance-holding and local-receiving-account product; Pay.net is a payment gateway that routes transactions across rails at the point of acceptance or settlement. Pay.net does not hold multi-currency balances or issue local receiving accounts. Many businesses use both.

Which platform has better FX rates?

Airwallex's core product strength is FX conversion priced close to interbank mid-market rates, which is generally stronger than what payment gateways (including Pay.net) offer as an incidental part of rail routing. For businesses where FX cost is the primary driver, Airwallex's dedicated FX infrastructure is the better fit.

Which platform is better for cross-border B2B payments?

It depends on the problem: for holding and converting multi-currency treasury balances, Airwallex. For routing a specific large B2B payment to the cheapest and fastest settlement rail (including stablecoin at 0.3% or FedNow for domestic legs), Pay.net. Many large cross-border businesses use both at different layers of their payment stack.
