Cross-Border Payments for SG SMBs Selling Into ASEAN

Cross-border payments for Singapore SMBs used to mean a SWIFT transfer, a two-day wait and a fee you only saw after the money landed. For a growing share of ASEAN transactions, that is no longer true. A customer in Bangkok can pay a Singapore account in minutes with a phone number, and a shopper from Jakarta can scan a NETS QR code at an Orchard Road counter with their own banking app.

The infrastructure has changed faster than most finance teams have. This post sets out what works today, what is coming in 2027, and how a Singapore business selling into the region can set up its payments to use both.

Which real-time payment links does Singapore already have?

At home, SGQR and PayNow already settle in seconds. Across borders, the Monetary Authority of Singapore has built links country by country since 2021:

• Thailand (April 2021). PayNow and PromptPay were linked in what MAS called the first linkage of its kind globally. Transfers of up to S$1,000 a day use a mobile number.
• India (February 2023). PayNow connected to UPI. NPCI added 13 more Indian banks to the link in July 2025, bringing the total to 19.
• Malaysia (March and November 2023). NETS QR and DuitNow QR were linked for retail payments, then PayNow and DuitNow were linked for instant transfers of up to S$1,000 or MYR 3,000 a day.
• Indonesia (November 2023). QRIS and NETS QR were linked, so shoppers in each country can pay merchants in the other by scanning a local QR code.

The Malaysia link was also the first to let non-bank institutions take part from day one. That matters for SMBs, because many already hold accounts with licensed payment providers rather than only with the big three banks.

What do these links do well for a Singapore SMB?

They are strongest at the consumer end of the business.

A Singapore retailer, F&B operator or attraction that serves Malaysian and Indonesian visitors can accept payment from their home apps with no card fees in the middle and no currency guesswork for the customer. A services firm with clients in Thailand can receive small payments in minutes instead of days. A business with staff or contractors in India can pay them through UPI at low cost.

Getting QR acceptance running is usually a conversation with your existing acquirer rather than a new project. Ask whether your terminals and printed codes accept NETS QR with the regional linkages switched on, and whether the settlement report separates foreign-wallet payments from local ones. That second question matters for marketing as much as finance. If you can see that 18% of weekend revenue at one outlet comes from Malaysian visitors, you know where to run your next promotion.

The daily caps set the shape of it. At S$1,000 a day, these links suit retail transactions, deposits, small service fees and payroll top-ups. They were not designed for a S$40,000 supplier invoice.

How should SMBs handle larger B2B payments into ASEAN?

For invoices above the caps, the practical answer in 2026 is a payment orchestration layer: one integration in your systems that routes each payment to the cheapest suitable rail.

A typical setup for a Singapore company billing customers in four ASEAN markets looks like this:

1. Local collection accounts. A licensed provider gives you a Malaysian, Thai or Indonesian account number, so customers pay you domestically and you receive Singapore dollars.
2. Real-time links for small amounts. Anything under the daily cap goes through PayNow links.
3. Bank transfer for the rest. Large or irregular payments use your bank’s cross-border transfer, ideally at a negotiated FX rate.
4. One reconciliation feed. All three rails post into your accounting system with the invoice number attached.

Choosing a provider for steps one and three comes down to three checks: whether it holds a Major Payment Institution licence from MAS, which ASEAN currencies it can collect in locally, and whether it offers an API your accounting system or ERP can call directly. The last one decides whether your team gets a live feed or a monthly CSV export.

Step four is where most of the saved time comes from. The worst part of cross-border receivables is rarely the fee. It is the finance team matching an unlabelled MYR deposit to the right invoice three days later. A good integration passes the invoice reference through the payment so reconciliation runs on its own.

What changes when Project Nexus goes live?

Bilateral links do not scale well. Five countries linked one-to-one need ten separate links, each negotiated and maintained on its own. Nexus replaces that with one gateway that each country’s instant payment system connects to once.

The project started at the Bank for International Settlements and now runs through Nexus Global Payments, a not-for-profit incorporated in Singapore in March 2025. In February 2026 it appointed a joint venture of PayNet (Malaysia) and NETS (Singapore) as technical operator, with AWS and Endava supporting the build. Technical development began in early 2026 and go-live is targeted for 2027. The founding members come from India, Malaysia, the Philippines, Singapore and Thailand.

For SMB planning, two points follow. Nexus is a 2027 event, so do not design 2026 operations around it. And it rewards businesses whose systems already handle instant payments well, because adding a new country later becomes a configuration change rather than a new project.

Four habits of SMBs that get cross-border payments right

Singapore SMBs that run smooth regional payments tend to share four habits:

• They collect locally. Customers pay in their own currency to a local account, which removes the most common reason invoices go unpaid: a buyer who does not want to deal with an overseas transfer.
• They keep the invoice reference attached. Every payment carries the invoice number end to end, so the accounting system matches it automatically.
• They review FX quarterly. Someone checks what the business actually paid in spread and fees each quarter and renegotiates once volume justifies it.
• They build for more rails. Payment logic sits in one service, not scattered across the website, the ERP and a spreadsheet, so adding Nexus or a new provider in 2027 is a small change.

None of these needs a large budget. The fourth one does need a deliberate integration decision, and it is cheaper to make now than after the business has added two more markets.

If your company is also planning its 2027 budget, the EDGE Grant from Enterprise Singapore supports up to 70% of qualifying internationalisation costs for SMEs, which can include work tied to entering new markets.

Frequently Asked Questions

Which countries can Singapore send instant payments to through PayNow?

PayNow links to Thailand’s PromptPay (since April 2021), India’s UPI (since February 2023) and Malaysia’s DuitNow (since November 2023). Transfers settle in minutes using a mobile number or virtual payment address.

Can Singapore businesses use PayNow cross-border links for supplier invoices?

Mostly not. The links were built for person-to-person and retail payments, and MAS set limits of S$1,000 a day on the Thailand and Malaysia links. B2B invoices still run on bank transfers or licensed payment providers.

What is Project Nexus and when does it go live?

Nexus is a scheme that connects domestic instant payment systems through one shared gateway instead of many bilateral links. Nexus Global Payments appointed a PayNet and NETS joint venture as technical operator in February 2026, with go-live targeted for 2027.

Can tourists from Indonesia and Malaysia pay at Singapore shops with their own apps?

Yes, where the merchant accepts NETS QR through a participating acquirer. Indonesian shoppers can scan with QRIS-enabled apps and Malaysian shoppers with DuitNow QR apps, and the merchant receives Singapore dollars.
