5 Leading B2B Cross-Border Payment Platforms for Global Business

Cross-border B2B payments are entering a new phase.

A decade ago, any company wanting to pay a supplier in Manila, invoice a customer in São Paulo, or pay a remote contractor in Nairobi had effectively one option. They had to navigate correspondent banking, eat the FX markup, and wait several days for settlement.

Today, a new generation of platforms offers direct connections to local payment systems, real-time settlement, multi-currency accounts, and increasingly, stablecoin rails. All of it through a single API.

The result is a category that has graduated from "SWIFT alternative" to full-stack financial infrastructure for global businesses.

The scale is already significant. In its most recent fiscal quarter, Wise alone processed USD 66.2B (£49.4B) in cross-border transactions, up 26% year-over-year. Airwallex reports roughly USD 100B in annualized payment volume.

Specialist networks like Thunes are now cited by Juniper Research as competing directly with Swift and Visa on the metrics that matter most to modern businesses: speed, coverage, transparency, and cost.

Here are five platforms currently defining the B2B cross-border payments category in 2026, ranked by a mix of volume, reach, product breadth, and competitive momentum.

1. Wise Platform

HQ: London, U.K.

Wise was founded as TransferWise in January 2011 by Estonian co-founders Mr. Kristo Käärmann (CEO) and Mr. Taavet Hinrikus. The idea came from the duo's own frustration with bank FX markups while moving money between Estonia and the U.K.

They solved it with a peer-to-peer matching model that cut out correspondent banking.

The company went public via direct listing on the London Stock Exchange in July 2021 at an $10B (£8B) market cap. It rebranded from TransferWise to Wise alongside the listing and is currently pursuing a secondary Nasdaq listing in 2026. Wise Platform is its B2B infrastructure arm.

Wise Platform gives banks and businesses access to one of the largest direct-connected cross-border networks available. It supports 40+ currencies and holds 80 regulatory licenses globally.

The platform has direct membership in eight domestic faster-payments systems: Australia, Brazil, Europe, Hungary, Japan, the Philippines, Singapore, and the U.K. It also partners with 90+ banks worldwide. In January 2026, Wise became one of the first payment institutions granted membership to Payments Canada, adding another direct rail.

The platform is powered by 950+ engineers and integrates via API or Swift.

It serves 11.3M active customers.

Roughly 80% of Platform-routed payments settle instantly, and 88% land within 24 hours. Platform customers include Bank Mandiri in Indonesia, SME neobank Aspire in Southeast Asia, Malaysian bank MBSB, and Upwork for freelancer payouts.

For banks modernizing their correspondent banking stack or SME platforms needing embedded global payments, Wise Platform is one of the clearest category leaders by volume and cost transparency.

2. Thunes

HQ: Singapore

Thunes was spun out of TransferTo, a Singapore-based mobile payments business founded in 2005. The cross-border payments arm branched off in 2016 under co-founders Mr. Peter De Caluwe (CEO) and Mr. Eric Barbier.

The rebrand to Thunes was completed in early 2019. De Caluwe led the company through its early years, moved into a Deputy Chairman role in January 2024, and returned as CEO in October 2025 after the 18-month tenure of former Worldpay executive Mr. Floris de Kort.

The company has raised over USD 362M across five rounds. Its USD 150M Series D was led by Apis Partners and Vitruvian Partners. Key investors include Visa, Marshall Wace, Insight Partners, Bessemer Venture Partners, Helios Investment Partners, GGV Capital, and Checkout.com.

The Direct Global Network spans 140 countries, 90 currencies, and 220+ payment methods. It has direct connections to 145 mobile wallet brands including M-Pesa, GCash, AliPay, and WeChat Pay HK.

The platform is backed by 50 regulatory licenses, including MAS, FCA, ACPR, FinCEN, and 50 U.S. state money-transmitter licenses. It serves 720+ Network Members including Uber, Deliveroo, Grab, Airbnb, Payoneer, WorldRemit, Equity Bank, PayPal, and Remitly.

In-house products include the SmartX Treasury System for FX and liquidity automation and the Fortress Compliance Platform for monitoring and sanctions screening.

Recent strategic moves have focused on interoperability and stablecoin rails. Thunes extended its Pay-to-Banks and Pay-to-Wallets solutions to the 11,500 banks on Swift. In 2025, it also acquired Tilia, an all-in-one payments platform for online games, virtual worlds, and creator economies previously owned by Second Life's parent Linden Lab. and launched Pay-to-Stablecoin-Wallets.

It also partnered with Circle on USDC-based settlement.

In 2026, Juniper Research placed Thunes in the top three globally alongside Swift and Visa. The company also won Best Cross-Border Payment Solution at the MPE Awards 2026 and FStech's Cross-Border Payment Infrastructure of the Year. 

3. Nium

HQ: Singapore

Nium was founded in 2014 as Instarem by Mr. Prajit Nanu (CEO) and Mr. Michael Bermingham. It launched as a consumer remittance platform in Singapore.

The company pivoted to B2B payments in 2016 and rebranded to Nium in 2019. This established it as an infrastructure provider for banks, fintechs, and enterprises rather than an end user brand.

The company has raised over USD 250M from investors including Visa, Riverwood Capital, Tribe Capital, and NewView Capital. It has publicly targeted a US IPO for the end of 2026.

Nium's infrastructure spans 190+ countries, with real-time corridors in 100+ markets and support for 100 currencies. Local collections are available in 40 markets.

It holds licenses in 40+ jurisdictions, issues 38 million card tokens per year, and processes over USD 25B in annual volume.

As a principal card issuer of Visa, Mastercard, Discover, and UATP, Nium also runs closed-loop payment programs for airlines and travel. Customers include Emirates NBD, KBank, Ebury, MOIN, and Paycell.

2026 has been a milestone year for stablecoins. In March, Nium launched a dual-network stablecoin card issuance platform. It enables companies holding stablecoins to spend hundreds of millions of Visa and Mastercard acceptance points through a single API.

In April, Nium integrated Coinbase's USDC settlement infrastructure. Customers can now fund cross-border payouts in USDC and settle in local fiat, eliminating pre-funding requirements.

Combined with participation in Visa's stablecoin settlement pilot, these launches position Nium as one of the strongest bridges between fiat and digital-asset rails in the B2B category. 

4. Airwallex

HQ: Singapore / Melbourne, Australia

Airwallex got its start in Melbourne in 2015. The four founders, Mr. Jack Zhang (now CEO), Mr. Max Li, Ms. Lucy Liu, and Mr. Xijing Dai, were running a coffee-import side business at the time, and the FX fees they kept running into are what sparked the whole idea.

Since then, they've raised more than USD 1.2B from the likes of Tencent, Sequoia, Salesforce Ventures, DST Global, and Lone Pine. Growth is sitting at around 85% year-over-year.

Rather than just reselling other people's payment rails, Airwallex spent the last decade building its own. The setup is aimed at businesses that want accounts, acceptance, payouts, and card issuance pulled together in one place instead of stitched across five vendors.

They hold close to 90 regulatory licenses across roughly 50 markets, including MAS, FCA, HKMA, and ASIC, with direct hooks into local payment networks in over 120 countries and settlement in 90+ currencies.

On the platform itself: payments are accepted in 130+ currencies, collections support 160+ local payment methods, and physical and virtual cards can be issued in 50+ countries. Global Accounts let businesses receive money like a local in 20+ currencies across 70+ countries.

Annual volume is around USD 100B, with annualized revenue of roughly USD 1.3B.

In 2026, they pushed into unified online and in-store commerce with a new POS product, which finally lets multi-country businesses reconcile online and physical retail through a single platform. Banking licenses in the U.S. and U.K. are also on the table.

If you're a scaling SMB or enterprise that wants the whole stack (accounts, cards, acceptance, payouts) under one login, it's hard to beat. 

5. Payoneer

HQ: New York, U.S.

Payoneer (NASDAQ: PAYO) has been around since 2005, founded by Yuval Tal, which makes it one of the older players in cross-border fintech.

It went public through a SPAC merger in June 2021 and now serves close to 2 million active customers.

Its sweet spot is the global digital workforce and the marketplace economy. Think SMBs, freelancers, and e-commerce sellers. It's become the default payout pipe for Amazon, Fiverr, Upwork, Airbnb, and Walmart's marketplace, among others.

Revenue guidance for 2026 lands between USD 900M and USD 940M, and the company says it's moved more than USD 70B in funds since launch.

Payoneer covers cross-border payments in 200+ countries and territories and 70 currencies. The product mix includes multi-currency accounts, mass payout APIs, working-capital tools, and prepaid Mastercards. It's regulated across the U.S., U.K., EU, Hong Kong, Japan, Singapore, China, and Australia.

A few notable moves recently: in January 2026, the RBI gave it in-principle approval as a Cross-Border Payment Aggregator. That's a big deal given India's export economy is projected to clear USD 850B this year, and Payoneer's user base skews heavily toward exporters.

Then, in February, the company partnered with Bridge (now a Stripe company) to roll out embedded stablecoin capabilities through Q2. A few days later, it filed with the OCC to set up PAYO Digital Bank, N.A., a U.S. national trust bank purpose-built around stablecoin infrastructure for global businesses.

Read those moves together and the direction is pretty clear: Payoneer doesn't want to just be a cross-border payments layer anymore. It's positioning to become a full financial-services platform for the global gig and SMB economy. 

How to choose

The right platform really comes down to your corridors, your currencies, and the actual use case driving your volume, not whichever provider has the flashiest map on its homepage.

A SaaS business paying 200 contractors a month has nothing in common with a marketplace collecting from buyers in Brazil, and neither looks like a bank trying to modernize its Swift flows.

Quick read on each:

Wise Platform wins on raw volume and cost transparency, especially for retail-style cross-border flows.

Thunes is the one to look at for wallet-heavy emerging-market corridors. It's now mentioned in the same breath as Swift and Visa.

Nium is the strongest pick for real-time B2B infrastructure, card issuance, and stablecoin interoperability.

Airwallex has the widest SMB-to-enterprise stack if you want accounts, cards, and acceptance all in one place.

Payoneer owns the marketplace and freelance payout niche, especially for SMB exporters in emerging markets, and is now angling to become a regulated U.S. bank.

The thing they all have in common: they're each building for a world where moving money across borders feels as fast and boring as a domestic transfer. And that's not a thought experiment anymore. The G20's 2027 targets have made it the benchmark, and every serious B2B platform is scrambling to hit it.
