Considerations for building a successful banking app development solution

While figuring out the crucial aspects of building a successful banking app development solution, you will undoubtedly encounter a variety of challenges and questions as to what to include. It is easy to navigate many of them. Take a look at the most common considerations of building a banking app development solution – a comprehensive insight from Proquantic’s custom app development team; take a look:

Application interface must have a low entry threshold

Your banking app development solution will not be used by advanced smartphone-using customers, but it is also going to be used by people with specific or various difficulties in mastering unique interfaces. Quite often, it can be challenging to conceptualize a user-friendly yet creative interface; however, when you hire a dedicated team of UI/UX designers, it becomes easier.

Implement KYC (know your customer) and AML (anti-money laundering) tools

Or else, be ready to face some financial penalties! You are obligated to exclude the chance of inefficiently handling your customer data, and hence, you have to depend upon a professional who can develop a truly reliable system of authentication and authorization of the users.

You HAVE TO guarantee customer data privacy

Banking app development solutions must comply with more stringent security certifications than other regular apps, and if they fail to do so, they may face a hefty financial or administrative penalty. Challenges like cybersecurity or fraud evolve with technology upgrades as well, and they will always remain to combat them. You have to implement features and functionalities that commit strongly to securing customers' personal as well as account data with modern security parameters. In this case, partnering with a security-minded team of developers can help you navigate through this overly complex yet crucial challenge.

Implement payment-blocking features

You must implement features that enable the steadfast blocking of deposits or credit cards in suspicious scenarios, such as theft or loss. The users must have the ability to instantly connect to the accounting system for placing blocking requests.

Your banking app development solution must be compliant with all the needed regulatory requirements

Alongside being compliant with various security policies, ensure that it is also compliant with many other necessary and mandatory regulatory standards, such as offering an easy-to-navigate user experience for all users, including those with special needs.

Among other considerations, you may also wonder about which technologies you should choose or which platform you should build your app for. As mentioned earlier, by hiring a team of experts, you can get a 360-degree comprehensive solution for all your planning and, of course, worries!

Take a look at some of the predominant technologies or languages that are used to build OS-specific (iOS or Android) or cross-platform or hybrid mobile banking app development solutions:

The technology stack for online banking application development should be selected based on security, scalability, platform requirements, integration needs, and long-term maintenance. Financial institutions may choose native, cross-platform, or hybrid frameworks depending on their users and product roadmap.

Steps to build a banking app development solution – Proquantic’s guide

A successful mobile banking application development process requires more than feature planning. It must combine market research, user experience design, secure architecture, regulatory compliance, testing, and ongoing maintenance to deliver a trusted digital banking experience.

Start with research

Before moving ahead with development, initiate market research to identify market leaders and outsiders and assess their strengths and challenges. This step will help you compile a differentiated and winning list of specifications you want in your app. Research may take one to two months.

SWOT analysis is generally a go-to strategy at this phase, as it helps identify potential threats, opportunities, strengths, and weaknesses.

Create a prototype

A banking app development solution is a complex product, and typically, a prototype is built first based on the initial list of specifications drawn after gathering insights from the client. Once the prototype is approved, developers begin with the banking app software development process.

To enable the prototype to reflect the future product’s functionality, you have to conduct certain primary studies like:

• Communicating with product owner – At this step, the app owner has to communicate the expectations as well as needs revolving around the product being developed.
• Job stories – Focusing on the needs of the user using the formula 'simulation' ->'motivation'->'desired result.'
• Jobs to be done – It's comprehensive and brings out the scope of work to be done ahead. This study helps in the design of products that meet all user expectations.
• User stories – A standard formula of a user story looks like 'being <user type>, I want to <perform action> to <get result>.

Strengthen the app with global and local security standards

For banking software, there is a list of security protocols that safeguards sensitive customer and bank data – some of which are:

• CCPA
• PCI DSS
• PSD2
• GDPR

And more. The list is significantly extended and usually stricter than in the case of building an ordinary app. Before starting the banking app development solution-building process, ensure that the relevant and necessary standards are aligned with and that the planned functionalities comply with each of them.

Conceptualize the UI/UX part

This is the make-it-or-break-it point for every app. The segment usually consists of implementing functionality and business logic and enables the developers to demonstrate a functioning version of the product to clients.

Choose the right tech stack.

Before initiating the implementation of the technology for your banking app development solution to support its functionality, developers have to choose a tech stack that primarily focuses on the budget and goals of the clients. The software tools that developers use typically depend on the app's functional needs and the chosen operating system.

Start with the development

Once the final approvals are in place, developers begin implementing the banking app development solution's functionality. As the different stages of work are completed on the app, repeated testing is conducted to ensure the application functions as expected and as needed.

It is advised that clients regularly interact with the development teams and provide feedback on the progress to ensure that the final product meets expectations. This reduces the chances of editing at the end, and the workflow in the team increases.

Building a mobile banking app development solution typically takes three to eight months, depending on the app's complexity.

Banking app development solution release and maintenance

When the testing phase yields a satisfactory outcome, the product is launched for release and then supported by specialists from the development team, ensuring that any technical issues that arise during the process are promptly addressed.

Public apps are usually uploaded to the App Store and Google Play – depending on the chosen OS.

Remember, at this stage, the transferring cost of the application to public access does not end, and the client – you have to pay for support for certain technologies, server capacity, and integration with third-party payment gateways.

Apps must be improved and updated

As your business grows, the market needs to grow side-by-side. Your banking app development solution should be supplemented and optimized with the new functionality.

New market research will enable you to figure out more areas of potential optimization and improvement which makes the banking app development process cyclical.
