What Is Banking as a Service (BaaS)? Models, Benefits & Use Cases

Banking as a Service (BaaS) allows a licensed financial institution to provide regulated banking products and services to third parties through APIs. Rather than building and operating a bank themselves, fintechs, software companies and other organizations connect to banking infrastructure that enables them to offer financial services under their own brand.

Banking as a Service typically supports current and savings accounts, debit cards, payments, lending, account verification, identity services and compliance capabilities.

The licensed bank remains responsible for regulated banking activities, while the partner focuses on customer experience and product innovation.

A typical Banking as a Service (BaaS) ecosystem involves three participants working together to deliver embedded financial services:

● Licensed bank: Provides the regulated banking infrastructure, holds customer funds and ensures regulatory compliance.
● BaaS platform: Connects the bank with third-party businesses through APIs, enabling services such as account opening, payments, card issuing and compliance checks.
● Business or fintech: Delivers customer-facing financial products and experiences under its own brand.

For example, a retailer that wants to offer branded payment accounts does not need to obtain a banking licence. Instead, it connects to a BaaS platform that enables services such as account opening, payment processing, card issuing and compliance checks through APIs. Customers interact with the retailer’s application, while the licensed bank provides the regulated banking services behind the scenes.

Several market trends are driving adoption.

● Customers expect embedded financial services: Consumers increasingly expect financial products to appear within the digital services they already use. Buy Now, Pay Later, business payment accounts, embedded lending, digital wallets and marketplace payments all depend on banking infrastructure that can be integrated through APIs.
● Banks are creating new revenue streams: Rather than relying solely on traditional customer relationships, institutions can generate additional revenue by providing regulated banking infrastructure to partners, reaching customer segments they might never serve directly.
● Open Banking has accelerated API adoption: The revised Payment Services Directive (PSD2) established a regulatory framework for secure access to payment accounts through APIs across the European Union. While Open Banking and Banking as a Service are distinct models, PSD2 accelerated investment in API capabilities that also support BaaS.

According to the European Commission, PSD2 was introduced to foster innovation, increase competition and improve the security of digital payments across the European financial sector.

These terms are often confused, but they serve different purposes.

Banking as a Service (BaaS)
● Provides regulated banking products through APIs.
● Enables organizations to create new banking products and services.
● Used by fintechs, brands and software companies.
● Supports embedded financial services.

Open Banking
● Enables secure sharing of customer-authorized banking data through APIs.
● Provides access to existing customer financial information.
● Used by regulated third-party providers with customer consent.
● Supports data sharing and payment initiation.

In short: Open Banking enables secure access to customer-authorized financial data, while Banking as a Service enables organizations to deliver regulated banking products through licensed banking infrastructure.

Banks adopt different BaaS strategies depending on their objectives.

● Infrastructure provider: The bank supplies core banking capabilities while partners manage customer relationships.
This model emphasizes scale and operational efficiency.
● Embedded finance partner: In this model, the bank enables businesses to integrate financial services directly into existing digital products such as e-commerce platforms, enterprise software, gig economy applications and travel platforms.
● Digital bank enablement: Banks also use BaaS platforms to launch their own digital brands or support newly created neobanks. This approach combines modern banking infrastructure with new customer experiences.

Banking as a Service creates value for both banks and their partners. Organizations can launch financial products without building banking infrastructure from scratch, while banks generate new revenue by serving multiple partners through a single platform. API-first architecture also supports faster product innovation, cloud-native platforms improve scalability, and participation in broader digital ecosystems creates opportunities beyond traditional banking channels.

Industry research indicates that ecosystem-based business models are becoming an increasingly important driver of growth, innovation and customer engagement across financial services.

Like any business model, BaaS requires careful planning.

● Regulatory responsibility: Regardless of the delivery model, the licensed bank remains responsible for AML, KYC, fraud prevention, operational resilience and consumer protection. Technology supports these obligations but does not replace the governance, controls and oversight required to meet them.
● Partner governance: Banks must evaluate business models, risk profiles, operational controls and security standards. Strong governance is essential.
● Technology architecture: Successful BaaS depends on API-first integration, cloud-native infrastructure, identity management, monitoring and developer tools. Without this foundation, scaling partners and services becomes progressively more difficult.

Today, Banking as a Service supports a wide range of industries. Examples include:

● Retail: Retailers offer branded payment accounts and loyalty-linked financial products.
● Accounting software: Business platforms provide embedded accounts, invoicing and payment capabilities.
● Gig economy: Workers receive earnings through integrated banking services.
● Marketplaces: Platforms manage payments, settlements and merchant accounts.
● Digital banks: Neobanks build customer experiences while relying on modern banking infrastructure.

One example is Snappi, Greece’s first ECB-licensed neobank, developed using the Natech Banking Platform as its underlying banking infrastructure.

Natech provides a modular, cloud-native banking platform that enables financial institutions to deliver Banking as a Service through secure APIs. The platform combines core banking, digital channels, payments, AML, KYC, card management and API management within a single technology foundation that supports fintech partnerships, embedded finance providers and digital banking initiatives. This approach is reflected in the development of Snappi, which was designed not only as a digital bank but also as a foundation for future Banking as a Service opportunities.

Is Banking as a Service the same as Open Banking?
No. Open Banking enables regulated third parties to access customer-authorized financial data with the customer’s consent. Banking as a Service, by contrast, enables organizations to offer regulated banking products through licensed banking infrastructure.

Who uses Banking as a Service?
BaaS is used by fintechs, retailers, software providers, marketplaces, digital banks and other organizations that want to embed financial services into their products.

What technologies support Banking as a Service?
