What is Banking as a Service (BaaS)? How it Works for Businesses

What is banking as a service? Banking as a service (BaaS) is a model that allows financial and non-financial businesses to offer banking products and embedded finance solutions using licensed financial infrastructure – without building or holding their own banking licence – in today’s rapidly evolving digital world.

More specifically, banking as a service lets fintech startups, e-commerce platforms, marketplaces, and other businesses embed banking functions seamlessly into their offerings. It reduces barriers to entry, accelerates product development, and enables companies to compete in financial services without the traditional overhead of becoming a regulated bank.

The core objective of banking as a service is to empower businesses to scale effectively by enhancing their customer experience and offering increasingly sophisticated, customised financial solutions. The robust back end infrastructure supporting BaaS ensures regulatory compliance, security, and risk management.

By reaching underserved markets and enabling new product categories, BaaS also fosters competition, drives efficiency, and promotes financial inclusion—while helping businesses diversify revenue streams and optimise operational costs.

Quick answer: What is banking as a service?

Banking as a service (BaaS) is a model that allows non-financial businesses to offer banking products – such as accounts, payment processing, debit cards, and digital wallets – by accessing the infrastructure of a licensed financial institution through APIs. Rather than obtaining their own banking licence or building financial systems from scratch, companies integrate BaaS capabilities directly into their existing platforms and offer them to customers under their own brand.

Comparison with traditional banking models

Unlike traditional banks that operate standalone, BaaS leverages APIs and cloud-based technology to enable businesses to offer financial services without the need for a banking licence, thereby blurring the line between banking and other industries. Open banking is a regulatory framework that allows third-party access to consumer financial data, whereas BaaS enables non-financial businesses to offer banking services directly to consumers using that data.

The evolution of banking services reflects a shift towards digitalisation and customer-centricity. Application programming interfaces (APIs) play a crucial role in facilitating seamless integration of banking services into third-party platforms, allowing businesses to embed products like deposits, cards, and loans efficiently. Traditional banks faced disruption from agile fintechs offering specialised services and enhanced user experiences.

The growing rise to prominence of BaaS was also facilitated by regulatory changes that enabled licensed institutions like banks and fintechs to partner with other businesses, which expanded their overall reach and expedited the delivery of financial services through integrated APIs.

How does banking as a service work?

Banking as a service operates as a B2B model connecting regulated banks, BaaS platforms, and non-bank companies through a layered technology stack.

Here is how it works at each layer:

The licensed bank — provides the banking licence, capital, regulatory compliance, and core banking infrastructure. Without this layer, none of the banking services offered downstream would be legally permissible.

The BaaS technology layer — translates the bank’s core systems (which are often legacy infrastructure not built for modern API connectivity) into modern APIs that allow real-time interaction. The BaaS provider connects the licensed bank to the third-party business, managing the technology and security tasks in between. BaaS solutions typically include user management features such as user registration, authentication, authorization, and profile management. Security in BaaS often encompasses multi-factor authentication and password encryption to protect sensitive data. BaaS solutions frequently provide cloud-based data storage, allowing businesses to manage and store user data securely.

The non-bank business (the partner) — uses the APIs to embed banking services directly into its own platform or product, enabling them to build their own applications under their own branding. Customers interact with the business’s branded interface, while the licensed bank and BaaS layer handle everything behind the scenes.

BaaS enables non-banks to provide various white-label or embedded financial products — including checking accounts, payment processing, carte di debito, portafogli digitali, and lending — without building their own banking infrastructure. The BaaS provider or sponsor bank also handles KYC and AML checks as part of this arrangement, reducing the compliance burden on the partner business.

Benefits of BaaS for business

Businesses adopting BaaS benefit from expanded product offerings by integrating banking services seamlessly into their platforms, such as payment processing, valute multiple, and account management.  

And since they gain access to valuable financial data through APIs, they become able to better understand customer behaviour and preferences for targeted marketing and product development.  

Not only that, BaaS also improves customer experience by providing convenient and personalised financial services within the context of their existing interactions with the business, leading to increased engagement and loyalty.  

What are examples of banking as a service?

Banking as a service is already in use across a wide range of industries. Here are some of the most common examples:

• Fintech startups — use BaaS to offer financial products such as bank accounts, loans, and payment services, entering the market quickly without the capital and time investment of building regulated banking infrastructure from scratch.
• E-commerce platforms — leverage banking as a service to provide embedded payment solutions, including Buy Now Pay Later (BNPL) services, directly within their checkout flows.
• Gig economy platforms — use BaaS to manage payments to freelancers and contractors, enabling pagamenti immediati and flexible payment solutions that traditional banking cannot deliver at scale.
• Tech companies — integrate in-app wallets, peer-to-peer payments, and account management features into their platforms without developing banking infrastructure themselves.
• Traditional banks — some established banks offer BaaS services to tap into new customer segments and additional revenue streams, monetising their existing infrastructure without direct customer acquisition investment.

ConnectPay is an example of a BaaS provider that delivers API-driven financial services — including multi-currency IBANs, payment processing, virtual and physical debit cards, and embedded compliance — to businesses across fintech, e-commerce, and marketplace sectors.

Challenges and considerations in implementing BaaS

Implementing BaaS may sometimes come with certain regulatory challenges, as businesses are required to ensure strict compliance with complex financial regulations and data privacy laws.  

Likewise, technical integration may at times become fairly complex, given the need for seamless interoperability between the systems that businesses already have in place and their APIs.  

Some further issues may crop up due to specific partnership dynamics, such as negotiating terms, aligning strategic objectives, and maintaining effective communication between parties.  

Overcoming these hurdles requires careful planning, flexible risk management frameworks, and strong collaboration between all stakeholders to ensure successful implementation and ongoing regulatory compliance. 

Risk management in BaaS

Licenced financial institutions and their partners employ a variety of risk management strategies, beginning with the identification of potential risks associated with regulatory compliance, cybersecurity, operational resilience, and data privacy. Assessing these risks involves evaluating the impact and likelihood of each risk scenario on daily business activity and customer trust.  

Mitigation strategies include implementing robust security measures, regular audits and assessments, ensuring compliance with regulatory requirements, and maintaining contingency plans for business continuity.  

Collaboration and transparency between financial institutions and businesses are crucial for effective risk management, as they share responsibilities in safeguarding customer data and maintaining the integrity of financial services.  

It’s also a good idea to perform ongoing monitoring and regular communication, as this can help to identify emerging risks and the relevant mitigation strategies accordingly. 

Banking as a Service – regulatory landscape

Offering banking services via BaaS requires adherence to strict regulatory frameworks governing financial activities. Both businesses and financial institutions must comply with regulations, such as KYC, AML, and data protection laws like GDPR.  

Needless to say, they must also ensure compliance with industry-specific regulations, such as the PSD2 in Europe or the BSA in the United States. Regulatory compliance involves obtaining necessary licences, maintaining accurate records, ensuring security, and conducting regular audits.  

As you can probably guess, failure to comply with these regulations may result in hefty fines, reputational damage, and legal consequences. For this reason, a thorough understanding and strict adherence to regulatory requirements are essential for successful operation within the BaaS framework. Luckily, however, some BaaS solutions offer embedded finance compliance, taking the handling of legalities off your shoulders altogether.

In Europe, the regulatory framework for banking as a service is primarily governed by PSD2, which sets the rules for payment service providers and enables the open API access that BaaS depends on. GDPR governs how payment and customer data is processed and stored.

Regulators are also intensifying their focus on BaaS partnerships specifically, scrutinising the compliance responsibilities shared between licensed banks and their non-bank partners to ensure consumer protection is maintained throughout the chain.

The future of BaaS and emerging trends

The future of BaaS is likely to witness further technological advancements, such as the integration of blockchain for enhanced security and transparency in transactions. At the same time, AI and machine learning algorithms are enabling more personalised financial services, driven by predictive analytics and behavioural insights.  

Furthermore, ongoing market shifts are ushering in ever more extensive collaboration between fintechs and businesses, fostering a more interconnected financial ecosystem.  

There’s also a very good chance that regulatory developments will shape the landscape further, with regulators imposing stricter compliance requirements to ensure consumer protection and data privacy. As BaaS continues to evolve, it will almost certainly lead to greater financial inclusion, innovation, and competition, ultimately reshaping the way financial services are delivered and experienced worldwide. 

What’s the economic impact of BaaS?

BaaS brings a host of benefits to businesses, such as cost savings by eliminating the need for large upfront investments in infrastructure and software. Subscription-based models allow for predictable expenses and scalability, reducing financial risks. BaaS also creates revenue generation opportunities through flexible pricing structures and value-added services, which caters to diverse customer needs.  

What’s more, BaaS fosters innovation by encouraging rapid experimentation and customisation, leading to the development of tailored solutions. This innovation not only drives growth within individual businesses but also stimulates economic expansion by enhancing productivity and competitiveness across industries.  

Looked at broadly, BaaS accelerates economic growth by optimising resource allocation, encouraging entrepreneurship, and facilitating technological advancement. 

The role of BaaS in financial inclusion

Banking as a Service promotes financial inclusion by empowering businesses to deliver tailored financial services to underserved or unbanked populations. Through cloud-based platforms and scalable solutions, BaaS providers enable companies to develop cost-effective and accessible financial products, such as mobile banking, microloans, and digital payment systems. These services cater to the specific needs and constraints of marginalised communities, offering convenient access to banking and financial tools.  

Moreover, BaaS fosters innovation by allowing businesses to leverage data analytics and artificial intelligence to assess creditworthiness and mitigate risks – a key part of expanding access to financial services for previously excluded populations. Thus, by democratising financial services, BaaS plays a pivotal role in promoting economic empowerment and fostering inclusive growth.
