Strategic Payment Trends for E-Commerce Merchants in 2026

In 2026, the payments landscape for e-commerce is transformed by the rollout of PSD3 across the EU and UK. Merchants and payment service providers (PSPs) must navigate stricter regulatory requirements, evolving fraud threats, and the rapid adoption of alternative payment methods. This analysis highlights three pivotal trends, each with direct implications for merchant conversion, approval rates, fraud exposure, and revenue growth.

Acquirer-agnostic payment gateways such as NOIRE empower merchants to route online payments across multiple PSPs and acquirers, enhancing transaction resilience, approval rates, and compliance for e-commerce payments.

PSD3: Compliance, Fraud Liability, and Merchant Impact

PSD3, coming into force from late 2025, enforces more rigorous Strong Customer Authentication (SCA) and shifts greater fraud liability onto PSPs and acquirers. Enhanced transaction risk analysis (TRA) and mandatory dynamic linking for remote electronic payments are now required. Card scheme rules from Visa and Mastercard impose stricter penalties for insufficient fraud controls, aligning with regulatory direction.

Merchants are under increased scrutiny for first-party fraud, where legitimate transactions are disputed by customers. Exceeding chargeback thresholds can result in fines or restrictions under scheme and regulatory frameworks.

• PSPs must deploy advanced, AI-driven monitoring to comply with new TRA obligations.
• Acquirers are primarily liable for authorised push payment (APP) fraud unless merchant negligence is established.

For merchants, non-compliance can lead to higher costs and rejected transactions, reducing approval rates and impacting revenue. Relying on a single acquirer increases operational risk. By leveraging an acquirer-agnostic payment gateway, merchants can diversify transaction routing, maintain approval rates during peak periods, and protect revenue against chargeback spikes. Tim Thompson, CEO of NOIRE, comments: “PSD3 rewards orchestration—merchants routing smartly see 20% fewer disputes.”

Alternative Payment Methods: A2A, Wallets, and BNPL Integration

Open banking is accelerating the adoption of account-to-account (A2A) payments, now embedded in leading digital wallets and Buy Now, Pay Later (BNPL) solutions. In the UK and EU, A2A transaction volumes are rising as consumers prefer instant bank transfers for lower fees and faster settlement. Payment models such as PayTo (Australia) and Request to Pay (UK/EU) are increasingly integrated into e-commerce checkouts by PSPs.

Digital wallets like Apple Pay and Google Pay are evolving to support A2A rails, reducing merchant reliance on card networks. Merchants adopting these methods benefit from faster settlement times and reduced processing costs.

• A2A payments eliminate card scheme fees, making them attractive for high-value e-commerce transactions.
• BNPL providers are incorporating A2A for real-time affordability checks and instant funding.

For merchants, integrating A2A and wallet payments lifts approval rates—especially among underbanked customers—boosting conversion and revenue. Fraud risk is reduced due to bank-verified transactions. An acquirer-agnostic payment gateway enables seamless routing of A2A, wallet, and card payments, maximising sales opportunities without major integration changes.

Cross-Border Payments: Local Acquiring and Regulatory Compliance

Cross-border e-commerce payments are challenged by currency volatility, inconsistent approval rates, and local regulatory requirements. Local acquiring—partnering with regional acquirers—has become essential for compliance and optimising transaction performance in key markets.

Merchants relying on a single acquirer often see declining approval rates in emerging markets due to local scheme restrictions. Payment orchestration platforms now use BIN intelligence, geographic data, and dynamic FX management to optimise routing and compliance.

• Local acquirers improve approval rates in regions such as Asia and Latin America by navigating domestic schemes and regulations.
• Orchestration solutions distribute transaction traffic, reducing downtime and exposure to single-provider outages.

For merchants, single-acquirer setups risk revenue loss from regional blocks and lower approval rates in volatile markets. Diversifying through local acquiring and acquirer-agnostic gateways increases approval rates, broadens market access, and mitigates FX risk—directly supporting international revenue growth. NOIRE’s platform exemplifies this approach, integrating global PSPs with local partners for optimised e-commerce payments.

Merchant Actions: Building Resilience and Revenue

To maximise conversion and revenue while managing PSD3 risk, merchants should implement acquirer-agnostic gateways to orchestrate payments across compliant providers. Test A2A and local acquiring options in controlled environments to benchmark performance. Regularly monitor chargebacks against scheme and regulatory thresholds. These steps strengthen payment resilience and support higher approval rates.

PSPs should prioritise advanced TRA tools and robust cross-border routing. E-commerce leaders benefit most from integrated platforms that support cards, A2A, wallets, and BNPL in a unified checkout experience.

Frequently Asked Questions

What is PSD3 and how does it affect online payments?

PSD3 updates SCA and fraud liability rules for EU/UK payments, shifting more responsibility to PSPs and acquirers. Merchants can reduce risk but must use compliant, acquirer-agnostic gateways to maintain approval rates.

How do A2A payments impact merchant revenue?

A2A payments lower processing costs and increase approval rates, driving higher conversion. Integration via open banking APIs can deliver immediate revenue benefits.

Why diversify acquirers for cross-border e-commerce?

Local acquiring raises approval rates in target markets, reduces FX exposure, and limits downtime risk. Acquirer-agnostic routing supports consistent revenue growth.

What are the main fraud risks under PSD3?

First-party fraud and APP scams are increasing; liability is shifting to acquirers. Merchants can reduce exposure by using AI-driven orchestration and robust TRA.

How does payment orchestration optimise e-commerce checkouts?

Orchestration routes transactions across multiple providers, improving approval rates and conversion while ensuring compliance with scheme and regulatory requirements.

Is NOIRE suitable for PSPs managing high-volume payments?

Yes, NOIRE’s acquirer-agnostic architecture supports PSPs with PSD3 compliance, A2A and cross-border routing, and scalable e-commerce payments.
