How Banking-as-a-Service(BaaS) drives growth in Fintech?

The banking industry is experiencing a massive technology shift. Thanks to technology innovation and ubiquitous online accessibility that pushed banks to get into the bandwagon of transformation. 

Though banks initiated the process automation, they still find it difficult to pace with today’s digitized financial services that are consumer-centric. The traditional banking services are being disrupted by fintech to introduce innovative, multi-channel banking solutions. Leveraging the power of fintech to offer digitally innovative solutions such as digital wallets, P2P lending, and payments give an opportunity to engage with the tech-savvy consumers of this era. Therefore, to stay ahead in the curve and be digitally relevant, banks need to rethink their approach to service delivery. 

To stay competitive, Banking-as-a-Service (BaaS) comes to your rescue. It is a toolkit that helps banks quickly enter new markets and accelerate to meet the demands of digital consumers and offer an exclusive suite of profitable services. 

Before diving into the depth of BaaS, first let us see what is BaaS all about.

What is Banking-as-a-Service (BaaS)?

Banking-as-a-Service or BaaS can be termed as an end-to-end process where Fintech, non-fintech, fintech developers, or any third party can leverage the benefits of financial services by accessing and executing the services without the need for developing them.  

With BaaS, third parties can access the bank’s core systems, and functionalities and integrate them with financial services like banking, payments into their tailored products. BaaS provides banks a platform to embrace a modular way of working into the fintech ecosystem and establishes a connection through APIs.

How does BaaS work?

The working of BaaS is explained in the diagram below. It has three steps:

1. Any third-party provider, for example, fintech pays a fee to access the BaaS platform. This is the first step in the BaaS process.

2. Once the request is sent by the fintech to access the BaaS platform, the financial institution opens its APIs to the third-party provider.

3. This enables the fintech to access the systems and information that helps in building new banking products and solutions.

The products that are built by the third-party providers cater to the market requirements and customer demands, focusing on enhancing the customer experience.

The 3 Key Aspects for Embracing BaaS

Banks need to embrace BaaS to succeed. To leverage the benefits of BaaS, banks need to consider the following three key aspects:

1. API revolution

With the widespread adoption of API technology, the emergence of BaaS came into existence. APIs aren’t new in the market, but for banks, their application was limited.

Earlier, third-party financial software providers would offer APIs to their clients (Banks) to meet the individual business needs by adapting to the software. Recently, the open-source wave has pushed the software vendors for making the APIs accessible to any customer who wants to use them. With more open-source movement gaining momentum, the software vendors started making their products available to the users interested in accessing them via APIs. It became a plug-and-play agreement where the buyers can ask for software and pay for their use rather than buying the entire entity. This entire process is known as Software as a Service (SaaS). This kind of service is available in Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) as well.

This business model is now knocking on the doors of Banks as well. Banks with this model will provide API access to users to their financial services. Businesses can tailor-made new products and services from a wide range of available financial services that fulfill their and their customer needs. In other words, businesses will create financial platforms through which they can offer their banking services. This is Banking-as-a-Service (BaaS).

Banks leverage the benefits of API to enable data sharing with fintech and developers. This will further help the third-party partners to develop enterprise digital solutions like mobile payments, P2P lending solutions, digital wallets, and many more for the customers. Also, with these kinds of advancements, banks need to accept their role as active participants and not owners always for the end-to-end user experience.

 2. Open Banking with BaaS

With open banking, banks offer customers to access and share financial data of the customer that is owned by the bank. Open banking allows customers to compare the products offered by various financial institutions and permits them to choose the best that fits their requirements and needs. Open banking offers customers the ease of fund transfers and accounts from one financial institution to another without hassles.

But with open banking, though a customer can get information about the features of a transaction account from multiple banks, he has to transact with a bank he has an account with, which isn’t the case with BaaS. BaaS allows a customer to access the transaction services offered by any regulated bank, even if he isn’t a customer of that bank.

BaaS offers businesses to choose the best suitable products for themselves from a wide array of service providers without the concern to manage the relationship with all the service providers. Also, BaaS provides businesses with faster accessibility, payment security, and other top-notch financial services through regulated banks in spite of the fact that they don’t have an account with those banks.

3. User experience

There is a rapid shift in customer demands. Customers expect to get served as soon as possible. They expect empathy towards their problems and require an immediate solution. Financial services are quite personal, affecting everyday lives. When your business can actually solve the customers’ pain points and resonate well, establishing a connection with them, you get to win their loyalty and retention.

With the growing capabilities of technology, financial offerings have become well-suited to modernized demands of customers. There is no thumb rule where the end-user has to have knowledge of BaaS. They are only concerned with the service and product that they get is highly secure, safe, and fast.

BaaS allows the sharing of data to third-party providers. This facilitates in building innovative and highly-relevant, customer-led digital solutions such as virtual assistants, financial robo advisors, and so on. Such digital solutions attract customers and result in higher engagement with your financial services, increasing your customer base and retention rate, while reducing costs.

Common BaaS Use Cases

1. Quicker time to market: When third-party providers access the bank’s functionalities, they get to combat some development hurdles.

Technology: Fintech development companies provide services that enable third-parties to communicate with the banks. This is done with a cloud-native technology stack. Therefore, when you partner with a leading fintech app development company, try to understand the design and development process of your fintech product and also check if it matches your requirements of speed and agility.

One of the biggest advantages of building cloud native solutions is it gives the fintech development company an opportunity to nimble and work in an agile environment, making them easy to scale as per the market requirements.

Process: BaaS brings in a set of requirements for the companies that are looking to incorporate financial services.

BaaS makes it a mandate for companies to operate within the defined regulatory compliances and legal framework of the federal and governing bodies. This becomes one of the main challenges that BaaS comes with and companies find it often difficult to build a process around this.

However, if your partner fintech firm establishes a robust framework with diligence and monitoring with stronger lines of communication with the bank, it will reduce the time for onboarding the services of your partner firm, giving you an opportunity for quicker time to market with better banking and payments to your customers.
