- South-East Asia has evolved into a payments-first digital economy, with rapid growth driven largely by digital financial services and mobile payments overtaking cards.
- Persistent inefficiencies in acquiring, cross-border payments, and fragmented regulatory frameworks create friction, making seamless, trustworthy transactions difficult to achieve at scale.
- Payment orchestration and AI-driven optimisation are becoming essential for improving performance, managing complexity, and enabling scalable, high-conversion digital commerce across the region.
South-East Asia has moved beyond the label of “emerging” and into something far more consequential: a payments-first economic region operating at real scale.
The region’s digital economy is on track to surpass $300 billion in gross merchandise value in 2025 – 1.5 times the forecast made just ten years ago, with both GMV and revenue growing at approximately 15% year over year. Digital financial services (DFS) are a dominant force within this growth, with digital payments and lending accounting for over 90% of total DFS revenue. And critically, by 2024, the total value of mobile payments surpassed that of card-based transactions in every South-East Asian country.
Consumer expectations have shifted permanently; digital channels have become the default. This creates a structural asymmetry, as demand for seamless payments accelerates faster than the infrastructure that supports it can develop. Merchants expect near-perfect success rates, real-time confirmation, and frictionless experiences, but the underlying systems often remain fragmented. It is here, in the gap between expectation and capability, that the next phase of innovation will be defined.
Acquiring, cross-border, and trust
Unfortunately, value leakages persist across the payments lifecycle.
Merchant acquiring is one of the clearest examples. Traditional banks, long dominant in this space, are losing ground to more agile fintech players. Merchants are increasingly prioritising ease of integration, faster onboarding, and transparent pricing over legacy relationships. If a provider can deliver higher approval rates with fewer operational bottlenecks, switching becomes a no-brainer.
Cross-border payments compound the problem. Despite years of progress, most cross-border payments remain slow, opaque, and inefficient, due to their reliance on multiple correspondent banks and other intermediaries.
On top of this, each country in the Asia Pacific (APAC) region operates under its own digital commerce framework, covering licensing, data storage, taxation, and cross-border money movement. Indonesia and Vietnam have rules regarding onshore versus offshore acquiring and data storage. Thailand and Malaysia have specific requirements for fund repatriation and invoicing. India carries complex compliance obligations, including the goods and services tax (GST), TDS, and OPGSP guidelines for exporters.
For fast-moving digital-first businesses, interpreting and complying with each framework – while maintaining commercial velocity – is genuinely difficult.
Interoperability issues persist across the region: inconsistent payment systems and QR code standards continue to hinder seamless cross-border transactions, while digital payment gaps between urban and rural areas limit SME participation in the digital economy.
Progress is being made at the infrastructure level. In March 2025, central banks from Malaysia, the Philippines, Thailand, Singapore, and India formally established Nexus Global Payments. This multilateral manages the development of Project Nexus, a network which allows domestic payment systems to connect to a shared gateway.
But live cross-border transactions on Nexus are not expected until around 2027. In the meantime, merchants without local entities frequently find their transactions processed via international acquiring, classifying them as cross-border, which triggers higher merchant discount rates, foreign exchange (FX) volatility, and lower conversion rates as local payment methods and issuing banks remain wary of non-local merchants. At the centre of this, any payment failure directly impacts customer perception. Trust is make-or-break.
The technology bets that matter
Orchestration becomes critical. It acts as the control layer for payments – sitting above individual integrations and enabling intelligent, real-time decision-making. It determines how transactions are routed, when retries are triggered, and which payment method is prioritised based on context. Through orchestration, businesses can centralise their payment infrastructure on a single integration – enabling dynamic transaction routing, optimising simultaneously for cost, approval rate, and user experience.
The growing importance of orchestration is closely tied to the limitations of existing systems. Payment infrastructure in South-East Asia is inherently heterogeneous. A fintech launched in Singapore may look to serve Indonesia, the Philippines, and Thailand within a year. A travel platform serving Korean customers may want to tap into Japanese and South-East Asian travellers. But with every new market comes an added layer of payment complexity. Managing this through static integrations quickly becomes unmanageable. A dynamic orchestration layer allows merchants to adapt without rebuilding their entire stack.
Artificial intelligence (AI) is increasingly being layered into this control plane – particularly in fraud detection, routing optimisation, and transaction risk scoring. But the gap between AI ambition and operational readiness is real and growing. AI agents that don’t just recommend purchases but complete them autonomously – agentic commerce – are being deployed.
Agent-driven commerce could unlock an additional 1.5% to 2.5% conversion in global e-commerce, equivalent to roughly $240 billion in new revenue. Yet for this potential to be realised, the underlying payment infrastructure must be able to keep pace. AI models are only as effective as the systems they operate within.
Without clean data pipelines, robust observability, and clear fallback mechanisms, even sophisticated models can introduce more risk than value. Orchestration provides the necessary foundation.
A practical agenda for platform builders and product leaders
For product leaders and engineering teams operating in South-East Asia, the priorities are becoming clearer, even if execution remains complex.
The first is to focus relentlessly on payment performance. Incremental improvements in approval rates or latency translate into significant revenue gains at scale – particularly in high-volume markets where a fraction of a percentage point can represent millions in recovered transactions.
The second is to treat integrations as living systems rather than static connections. Each payment method, gateway, or regional partner introduces variability that must be continuously monitored and optimised.
The third is to embrace composability. To scale in APAC, merchants need more than local or bilateral setups – they need a cohesive regional payments strategy that supports local payment methods, leverages domestic acquiring rails to reduce costs, manages multi-currency FX exposure, and ensures compliance with country-specific regulations. Orchestration enables this by decoupling the merchant experience from the underlying infrastructure.
Finally, there is a need for realism around AI. It is a powerful tool, but not a shortcut. Effective deployment requires strong governance, explainability, and alignment with business objectives. In payments, where trust and reliability are paramount, these considerations are non-negotiable.

South-East Asia’s payments market is entering a more mature phase, where success will be defined less by access to growth and more by the ability to manage complexity. The opportunity remains substantial – but capturing it requires infrastructure thinking, not just ambition.
