What is banking as a service?

Banking as a Service (BaaS) is a financial industry concept that refers to the delivery of banking and financial services through a third-party platform or API (Application Programming Interface). 

Essentially, banking SaaS companies allow non-banks, such as fintech companies, startups, and others, to leverage the infrastructure and capabilities of traditional banks to provide various financial services to their own customers without having to hold a full banking license themselves.

In the BaaS model, banks make their services, such as account creation, payment processing, loan origination, and compliance, available through APIs that can be integrated with other companies’ systems. 

This allows these third-party companies to develop and offer their own financial products and services, such as digital wallets, money transfer apps, investment platforms, etc., without having to develop the entire underlying banking infrastructure from scratch.

Examples of BaaS and business partnership

The banking as a service model encompasses various industries, from technology companies to e-commerce, that provide banking services through a partnership with financial institutions. Below are some examples of partnerships and collaborations that involve banking as a service companies.

FinTech startups and traditional banks

In this case, a fintech startup partners with a traditional bank to offer a digital wallet service. For example, in partnership with Sutton Bank and Marqeta, Cash App provides its customers with a personalized debit card that enables both in-store transactions and hassle-free ATM cash withdrawals.

In addition, Lincoln Savings Bank enriches the Cash App experience by providing account and routing numbers, facilitating the effortless processing of incoming and outgoing ACH payments.

E-commerce platforms and payment services

An e-commerce platform partners with banking saas companies to provide a seamless payment experience. For example, an e-commerce giant like Shopify uses Stripe to optimally integrate SME bank accounts (held at Evolve) with its e-commerce platform. The main benefit is the creation of a comprehensive dashboard outside of the traditional banking system.

In addition, merchants using a credit account have faster access to funds generated by Stripe’s payment processing services. These embedded financial solutions not only strengthen customer engagement but also enrich their experience with additional financial offerings.

How does banking as a service work?

Banking as a Service (BaaS) enables non-banks, including fintech startups and technology companies, to offer financial services to their customers without having to build an entire banking system from scratch.

This is achieved by leveraging the established resources of traditional banks via APIs to provide a seamless and consistent user experience.

Here is a typical breakdown of the process:

  • 1. Engagement. Fintech companies subscribe to the BaaS platform.
  • 2. Solution development. Using APIs, these fintech companies develop innovative financial services solutions tailored to their target audience.
  • 3. Collaboration. Established financial institutions serve as BaaS providers and grant fintech companies access to their APIs to integrate their solutions.
