Modernising Bank Payments: How Banks Can Win in Merchant Acquiring

Banks have been the backbone of merchant acquiring. 

Their regulatory strength, trusted brands, and long-standing merchant relationships established them as the primary enablers of digital payments. 

Over the past decade, however, the landscape has evolved rapidly.

New-age acquirers—fintechs, orchestration platforms, and digital-first processors—have introduced new levels of speed, flexibility, and intelligence across onboarding, APIs, alternative payment methods, global acceptance, and analytics.

This shift does not reflect a lack of capability within banks. Rather, it highlights how quickly technology and merchant expectations have advanced.

Banks continue to hold significant advantages: deep trust, compliance expertise, settlement infrastructure, treasury strength, and the ability to serve merchants at scale.

By modernising their payments stack and adopting a more software-centric architecture, banks are well-positioned to lead the next phase of innovation in merchant acquiring.

The New Competitive Landscape

Merchant acquiring is no longer simple transaction processing – it has become a full-stack digital experience. 

Businesses today expect a single platform powering payments across web, app, in-store, QR, mobile wallets, and cross-border channels. 

They want clear visibility into authorisation rates, routing configurations, fees, and settlements, and the agility to add payment methods instantly.

Fintech acquirers anticipated this shift early. They built cloud-native platforms with modular APIs and orchestration layers separating checkout, routing, fraud, tokenisation, FX, and reconciliation. 

They ship improvements quickly, integrate regional payment methods in weeks, and offer real-time dashboards with actionable business insights.

Banks, by contrast, still often rely on legacy gateways stitched together with multiple vendor systems.

Onboarding takes weeks. Dashboards are fragmented. Routing logic is simplistic. Adding alternative payment methods takes months. Cross-border flows depend on outdated treasury processes.

The result? Merchants increasingly prefer agile acquirers – even when banks are more trusted.

But this isn’t a permanent disadvantage. With the right modernisation strategy and ecosystem partners, banks can match – and surpass – today’s challengers.

From Gateways to Platforms: Rethinking the Architecture

The first transformation is architectural. 

Banks must shift from monolithic gateways to modular, cloud-native payment platforms – where routing, fraud, tokenisation, settlement, and reconciliation operate as separate, scalable services.

This enables rapid integration of new payment methods like UPI, PayNow, Mada, or wallets; ensures omnichannel consistency; and accelerates product updates. 

More importantly, it gives merchants a unified interface rather than fragmented portals and reporting systems.

Several global banks are already pursuing this path – often partnering with platforms like Juspay that bring merchant-scale, cloud-native infrastructure that integrates with existing acquiring systems.

Reimagining Merchant Experience

Banks have traditionally designed their systems around internal processes – risk, compliance, settlement cycles, and batch systems. 

Today, however, merchants expect consumer-grade experiences. They want:

• Digital-first onboarding with modern APIs, SDKs, and sandbox environments – in hours, not weeks.
• Intuitive dashboards that provide deep operational insights into success-rates, declines, and settlements.
• Self-service capabilities – configuring PG settings, toggling payment methods, setting up webhooks, managing settlements, and more.

Banks must treat acquiring as a product, not as a service line. When banks match (or exceed) the merchant experience offered by fintech acquirers, they immediately become competitive again.

Success-Rate Engineering: The New Battleground

One of the biggest differentiators for modern acquirers is their ability to optimise authorisation rates. 

Even a 2–3% uplift can generate millions in additional revenue for merchants. Fintech acquirers invest heavily in real-time routing, intelligent retries, tokenisation, fraud scoring, device intelligence, and BIN-level decisioning.

Banks, on the other hand, often rely on static routing logic and legacy fraud systems.

But banks hold a hidden advantage – closer issuer relationships and deeper visibility into network-level patterns. 

Once modernised with real-time decisioning and adaptive routing, banks can outperform fintechs and shift merchant preference.

Competing in a Global Economy

Payments are no longer local. Even mid-sized merchants operate in multiple markets, and expect multi-currency pricing, local settlement, transparent FX, and compliance with local regulatory frameworks such as SCA or data localisation. 

They also expect support for local payment methods – wallets, account-to-account systems, national rails, and open-banking-based payments.

Banks must evolve from card-only acquiring to universal acceptance. Orchestration platforms are essential here – they enable banks to adopt new rails rapidly without lengthy integration cycles.

The Role of AI and Data

Banks sit on some of the richest datasets in financial infrastructure – issuer authorisation patterns, merchant risk behaviour, cross-border insights, and interchange flows. Historically, this data lived in silos.

Modern platforms change this. AI can predict issuer declines, optimise routing paths, enable adaptive fraud prevention, drive dynamic pricing, and provide merchants with performance intelligence.

Data is no longer a back-office asset – it is a competitive advantage.

Path to Modernisation

The transformation process requires both technology and organisational change. Banks must build cross-functional product-led teams and adopt a merchant-centric operating model. 

Equally important is building an ecosystem rather than going solo – working with orchestration providers, risk platforms, APM aggregators, and infrastructure partners such as Juspay to accelerate delivery and expand coverage.

Modernisation happens in phases – starting with orchestration and unified APIs, and progressing toward AI-driven routing, dynamic fee engines, expanded payment method coverage, and real-time operational intelligence.

The goal is not to rebuild everything – but to combine bank-grade trust with modern agility.

Banks Can Win This Race

The rise of fintech acquirers does not signal the decline of banks – it signals the need for reinvention. Banks remain uniquely positioned to win in merchant acquiring, backed by trust, scale, and regulatory credibility. 

What they need is a modern, modular, intelligence-driven payments stack that puts merchants at the centre.

The question is not whether banks can compete – it’s which banks will modernise fast enough to win.
