Pay-by-bank payments are reshaping the business-to-business payment landscape in 2026 with a trajectory that few industry observers anticipated even two years ago. What was once a niche alternative payment method confined to a handful of European markets has grown into a global movement, driven by open banking regulation, real-time payment infrastructure, and a fundamental shift in how businesses think about payment costs and settlement speed. For high-risk merchants and B2B enterprises that process large invoice volumes across borders, pay-by-bank is emerging as a transformative alternative to wire transfers, checks, and even virtual cards.
The numbers tell a compelling story. According to Juniper Research, global B2B pay-by-bank transaction values are projected to exceed $180 billion in 2026, up from roughly $75 billion in 2024. This represents a compound annual growth rate of over 55 percent, making pay-by-bank the fastest-growing B2B payment method by a wide margin. In the United Kingdom, where open banking-powered pay-by-bank has the deepest penetration, over 12 million B2B payments were processed via account-to-account rails in Q1 2026 alone, representing a 200 percent year-over-year increase. The trend is accelerating as more payment service providers integrate pay-by-bank capabilities into their B2B invoicing and checkout platforms.
How Pay-by-Bank Works in a B2B Context
The mechanics of pay-by-bank are deceptively simple but represent a fundamental departure from existing B2B payment methods. When a supplier invoices a buyer, the invoice includes a pay-by-bank option. The buyer authenticates through their online banking portal or a payment initiation service provider, confirms the payment amount and recipient account details, and authorizes the transfer. The funds move directly from the buyer's bank account to the supplier's bank account in real time through the underlying instant payment rail. There are no card networks, no interchange fees, no merchant discount rates, and no intermediary settlement delays.
In a B2B environment, pay-by-bank offers several structural advantages over credit cards. B2B credit card transactions typically incur interchange fees of 2.5 to 3.5 percent, with level 3 data requirements adding administrative overhead. Wire transfers cost $15 to $50 per transaction domestically and significantly more for cross-border payments. Pay-by-bank transactions, by contrast, typically cost a flat fee of $0.25 to $1.00 per transaction or a very small percentage that rarely exceeds 0.5 percent. For a business processing $2 million in monthly B2B invoices, switching from card payments to pay-by-bank could save $40,000 to $60,000 per month in processing costs alone.
The reconciliation advantages are equally significant. Pay-by-bank transactions carry structured remittance data that can be automatically matched to open invoices. The ISO 20022 messaging standard, which underpins most modern pay-by-bank systems, supports rich data fields including invoice numbers, purchase order references, line-item details, and tax information. This eliminates the manual reconciliation burden that plagues businesses dependent on wire transfers and checks, where remittance information is often embedded in free-text memo fields that require human interpretation.
Regional Adoption and Infrastructure
The adoption of B2B pay-by-bank varies significantly by region, reflecting differences in regulatory frameworks, instant payment infrastructure maturity, and open banking implementation timelines. Europe leads the market by a wide margin, driven by PSD2 open banking regulations and SEPA Instant payment infrastructure. The United Kingdom's open banking ecosystem, now five years into full production, has the most mature pay-by-bank infrastructure globally, with over 90 percent of UK business banking accounts accessible through open banking APIs. Payment initiation service providers like TrueLayer, Yapily, and Token.io process millions of B2B pay-by-bank transactions monthly, and major invoicing platforms including Xero, Sage, and QuickBooks now offer native pay-by-bank integration.
The United States is catching up rapidly, though the infrastructure differs from the European model. The Federal Reserve's FedNow service, which launched in July 2023, has seen accelerating B2B adoption through 2025 and into 2026. Over 1,200 financial institutions are now live on FedNow, and the service's native support for request-for-payment messages makes it well-suited for B2B invoice payments. The Clearing House's RTP network, which has been operational since 2017, processes a growing volume of B2B payments, particularly for same-day settlement use cases where speed matters more than the rich data payloads that ISO 20022 provides. Several fintech platforms have begun offering pay-by-bank as a B2B payment option using FedNow and RTP as the underlying settlement rails.
In Asia-Pacific, pay-by-bank B2B adoption is being driven by different dynamics. India's UPI, while primarily consumer-focused, is increasingly used for B2B transactions, with UPI-based B2B payments growing at over 80 percent year-over-year. Australia's New Payments Platform supports pay-by-bank with rich data capabilities, and Singapore's PayNow is expanding its B2B use cases. The fragmented nature of Asian payment systems means that pay-by-bank adoption in B2B tends to cluster around specific use cases rather than achieving the broad coverage seen in Europe.
Pay-by-Bank for High-Risk Merchants
For high-risk merchants, pay-by-bank presents a particularly compelling value proposition. High-risk businesses in sectors like nutraceuticals, CBD, subscription services, digital goods, and adult entertainment face persistent challenges with traditional card-not-present payment processing, including elevated chargeback ratios, rolling reserve requirements, and frequent account terminations. Pay-by-bank eliminates the chargeback mechanism entirely because the payment is an authenticated bank transfer. Once a buyer authorizes a pay-by-bank transaction through their banking portal, the payment is final and cannot be reversed through the chargeback system that plagues card-based processing.
This fundamental change in the risk profile of each transaction has significant implications for high-risk merchants. Payment processors and acquirers evaluate merchant risk primarily through the lens of chargeback ratios and fraud rates. Pay-by-bank transactions, because they are authenticated directly by the buyer's bank and settled in real time through instant payment rails, carry a fraction of the fraud and dispute risk of card payments. This can translate into lower reserve requirements, reduced processing holds, and more stable long-term processing relationships for high-risk merchants who adopt pay-by-bank as a primary B2B settlement method.
Another advantage for high-risk merchants is the elimination of the card network compliance burden. Visa and Mastercard compliance programs like VNDP, MNP, and the MATCH list create significant operational overhead for high-risk businesses and can effectively terminate a merchant's ability to process payments. Pay-by-bank operates outside the card network ecosystem entirely, meaning that high-risk merchants are not subject to card network fines, compliance program reviews, or MATCH listing for their pay-by-bank transactions. This independence from card network rules is a strategic advantage for businesses in volatile or heavily scrutinized verticals.
Integration and Implementation
Implementing pay-by-bank for B2B payments is becoming increasingly straightforward as payment orchestration platforms and invoicing software add native support. For merchants already using a payment orchestration platform, adding pay-by-bank typically requires a single API integration that routes transactions to the appropriate pay-by-bank provider based on the buyer's region and bank. Providers like TrueLayer, Tink, Plaid, and Yapily offer unified APIs that connect to multiple banks and payment rails across different markets, abstracting the complexity of individual bank integrations.
For high-risk merchants specifically, WebPayMe can facilitate connections to payment processors that support pay-by-bank as part of a multi-rail payment strategy. The key is to work with a payment partner that understands both the regulatory requirements of high-risk processing and the technical infrastructure needed to route B2B payments through pay-by-bank rails. As pay-by-bank adoption continues to accelerate through 2026 and into 2027, the competitive advantage for businesses that adopt early will only widen, particularly in B2B verticals where payment costs and settlement speed directly impact margins and cash flow.
