Latest technologies like predictive machine learning algorithms assist in developing a personalized experience for users.

Let’s now move on to our comprehensive guide on the bank software development process from end to end.

It will outline the complete development roadmap from software idea to its development and execution for any startup founder or business owner interested in investing in the digital banking industry.

Banking Software Development – A Guide

You will go through the following steps in the banking software development process:

Banking Software Idea

The first step is to decide on the banking service you want to provide through your software product. A good approach is to follow a need-based solution method.

This means you look into the needs of your potential customers and think about what will make their lives easier. Your aim is to provide a solution to a customer’s problem through your custom software.

With numerous banking software already available online, you must come up with a unique banking software solution that will make potential users stand up and take notice.

Consider this example, most companies refuse loan issuance to people with low credit history.

You could develop a software product giving loans to such individuals determining their eligibility from their financial information by using AI to help determine if they truly have the means to pay it back. 

Techniques like brainstorming and SWOT analysis really help in deciding the best business product idea.

Market Research and Feasibility Analysis

After deciding on your bank software idea, you need to conduct thorough market research. Look into similar software products, their user base, and features, and try to determine what they are missing. 

Also, dig into the types of consumers using the app in detail. What are their usage patterns, what do these users like in this particular piece of banking software, and what features are not worth investing in given the user trends, etc?

Feasibility Analysis is done in four ways:

  • Economical: To help you outline the cost/benefit analysis. This will help you decide if it is economically viable for you to build this banking product.
  • Technical: This will help you analyze the technical resources that you will need to complete your banking software product.
  • Timeline: To help you decide the duration of your banking software development process. The major development milestones, their completion timelines, etc. You can also further discuss the product development schedule with your software development partner.
  • Operational: This will help you figure out the required human resources, product usability, maintenance, support, etc.

Online tools, like SoGoSurvey and Living facts, can help you in conducting surveys and market research of real users using statistical data. 

Conducting a thorough feasibility analysis will help you with the next stage of choosing the right software development partner.

Choose the Software Development Partner

This is a crucial step in the process as the success of your banking software product depends on a knowledgeable, experienced, and reliable financial software development company.

For a complex software product like banking software, skip hiring freelance developers, as poor industry knowledge and technical skills will result in product failure or overruns.

Instead, opt for a hybrid company providing financial software development services via outsourced developers and dev teams.

Software development companies should have a wealth of experience developing a range of enterprise-level software solutions. 

A good company will have excellent product development and communication procedures in place. Most importantly, they will offer your company access to a range of skilled developers, each an expert in a particular programming domain.

Read our guide on choosing the right software development company for more information.

An in-house team of developers will take time and lots of energy to build. You will have to go through a recruitment and training process for each developer.

By outsourcing the banking project to a banking software development company, you will only have to go through a very brief vetting process as the company will have already done this for you. 

To make sure you get the right developer, focus your research on reviewing the company’s past projects (especially banking-related projects), case studies, client reviews, technical expertise, development practices, etc.

All you need to do then is to contact suitable software development companies, discuss the banking software project details with them, review their developers for their banking software development services, and get started working with your new remote software development partners.

Next, we will discuss the technical skills to look for in your developers.

Skills required in a banking software developer

The banking software is built using the latest technologies and tools to give seamless banking services and the best customer experience.

  • Web app development 

Web applications involve two development processes. Front-end and back-end.

  • Front-end Development

The front-end developers are responsible for implementing the user interface designed by the UI/UX designers by writing the code. The front-end developers should be skilled in CSS, HTML, and JavaScript. 

They should have adequate knowledge of JS libraries like jquery and React to build dynamic and interactive websites. JavaScript framework, Angular, is also popular today for building secure and robust web applications.

  • Back-end Development

The back-end developers deal with tasks such as functionality, performance, data integration, application security, etc. Java and Python are widely used for building financial products. 

Python is a simple-to-use programming language with English language-like syntax. It helps to build robust web applications while allowing developers to adopt an agile approach.

It has great features such as enabling developers to rework the code module and add new code as needed. 

Python also has an easy integration process with frameworks like Django. It is designed to allow for a fast MVP development process, which makes it very popular.

Java is another widely used programming language. It is lightweight and flexible, yet powerful enough to handle large volumes of data.

Java is a structured object-oriented programming language that is secure and reliable and includes out-of-the-box features like runtime constraints and an advanced security manager.

  • Mobile app development

The skills you will require in your mobile app developers will depend on the type of mobile banking application you want to launch. Each mobile device operating system calls for a separate skillset.

  • iOS App Development

Native iOS app development skills are required for devices operating on the iOS operating system such as the iPhone, iPad, etc. iOS developers should be skilled in Swift or Objective-C programming language. 

Swift is more used today for iOS app development due to its extensive library support that helps in building a secure and performance-efficient app.

Developers should have experience in using Apple Integrated Development Environment (IDE), Xcode, to build applications efficiently. 

Your development team should also be familiar with the Apple human interface guidelines required to design an Apple standard software product.

Developers should also have the skills to work with testing software like XCTest to build bug-free apps. 

  • Android App Development

Native Android app development skills are required for apps running on the Android operating system. Programming languages like Java and Kotlin are common for building secure and performance-efficient apps for Android devices.

Android app developers should be familiar with Android IDE like Android Studio and Android Software development toolkit (SDK) to develop efficient apps with maximum library support. 

Android app developers should be skilled in using testing tools like Espresso. They should know UI design requirements using Google’s Material Design Guide.

  • Secure Software development

As Banking software deals with users’ private and financial data, security is of primary importance. Your developers should be experts in implementing the latest cybersecurity and application security practices. 

They should be knowledgeable of the latest security threats like Denial of service, SQL injections, and scripting attacks.

They should also know the solutions to prevent them, for instance, data encryption algorithms like DES and RSA.

 Multi-factor authentication (MFA) and change of passwords are some basic standards to ensure application-level security, your app must include them.

Developers should be familiar with the Compliance-As-Code to ensure that your app complies with the correct security standards.

  • Cloud Computing

Cloud computing services are used in software development due to the flexibility and scalability that they offer.

Cloud computing services take the form of infrastructure, platforms, and software tools such as development environments and APIs, etc.

The advantage is that businesses no longer need to invest in physical IT infrastructure beyond a few laptops and a wifi connection.  

Infrastructure as a Service (IaaS) like Amazon Web Services and Microsoft Azure allows developers to work virtually on their cloud provider’s infrastructure.

Developers are only responsible for building the application and do not need to bother about hardware maintenance.

Platform as a Service (PaaS) like AWS Elastic Beanstalk and Google App Engine provide operating system services that allow management of application development IDEs as well as data storage in the cloud.

Software as a Service (SaaS) platform provides pre-configured software packages to users. Developers do not have to install or manage the software applications themselves.

Microsoft Office 365 is one such example of SaaS. Many software development tools allow access to predeveloped tools such as AI systems. 

  • Latest Technologies

The use of the latest technologies helps to build app functionalities to offer the best and more reliable customer experience.

  • Artificial Intelligence

Artificial Intelligence, especially machine learning algorithms, is widely used in financial and banking software to provide a personalized customer experience.

Predictive machine learning algorithms learn from user data trends and help to identify the best-fit services for individual users. 

Chatbots are another great feature popular for assisting customers. Chatbots can serve multiple users at the same time, 24/7, without ever getting tired.

Moreover, AI algorithms help improve chat-user interaction through techniques like Natural Language Processing  (NLP), which makes communication increasingly accurate and human-like. 

Developers should have expertise in using AI chatbot development and integration frameworks like Microsoft Bot Framework, IBM Watson, and Amazon Lex.

Plan the software development Strategy

After finding your team of developers, it is time to implement your financial software development strategy and workflow.

In the software industry, there are many software development methodologies and frameworks. 

The most widely used is the Agile methodology. This is the one we recommend. It goes well with companies looking for a speedy and manageable software development process. 

An agile product development strategy lets the developers work in small, cross-functional teams to develop software rapidly in iterations.

Each iteration builds up the product by enhancing its features per user requirements. Frameworks like Scrum and Kanban help to implement agile practices in the software development process. 

In this phase, you decide with your development team on the product iterations. Usually, the software development process starts with the essential software features.

In Agile, these iterations of software development are called ‘Sprints’.

Design and Develop

At this stage, you formally start the design of your software product. Remember that a good UI/UX interface will attract and retain more users.

Design an app with the help of UI/UX designers that is easy to use and avoids unnecessary complexities. 

The development of custom software solutions should start with the creation of a minimum viable product or an MVP. Your development team will roll out an MVP with the basic features for users to use.

Gradually, you will refine and scale up your software product with new features that are based on user-recommended improvements.

Test and Deploy

Make sure to launch bug-free banking software as the risk associated with banking products is huge. Conduct thorough testing of the product. 

Use QA testing tools to ensure the software product is working as planned. Use software tools like TestRail and RainForest for software product testing. 

Once satisfied, deploy the banking solution for the users to start using.

Market the Software Product

Marketing your banking software is essential. In the digital era, a software product can be commercialized through several channels. Some of these are:

  • Running Ads:

Run your software product ads by leveraging social media platforms like Instagram, YouTube, Google, etc. Invest in the channel with the maximum conversion rate.

  • Press Releases:

Reach out to news websites like PR Newswire, and submit articles showcasing your banking solution in detail. Your product press releases will find new audiences on these websites.

  • Online Presence:

Invest in an online presence by building your own website and linking it to your social media pages. Promote them on online platforms like Google and social media if you have the budget.
