The global banking system software market is expected to reach $57.8 billion by 2030, according to a report. The same report states that in 2023, the United States generated a revenue of $7.2 billion becoming the largest contributor to the worldwide banking system software market.

Different types of banking applications, like banking CRM, internet banking, payment software, banking document management software, etc., aim to automate banking business processes and allow users to access banking services from anywhere with convenience.

Let’s see how you can develop banking software and mark your share in the growing market.

Banking Software Development – A Guide

The banking software development process includes the following steps:

Banking Software Ideation

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. You aim to provide a solution to a customer’s problem through your software.

Consider the example where most companies refuse loan issuance to people with low credit history. You could develop a software product that gives loans to such individuals by determining their eligibility from their financial information. AI could enable the software to determine from the users’ data if they truly have the means to pay it back.

Techniques like brainstorming and SWOT analysis help decide the best business product idea by analyzing the strength, weaknesses, opportunities, and challenges with every software concept.

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. 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?

Feasibility Analysis is done in four ways:

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

Online tools, like SogoSurvey, help conduct online surveys and perform user market research using statistical data. Conducting a thorough feasibility analysis helps 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 partner.

For a complex software product like banking software, skip hiring freelance developers. Freelance marketplaces give space to all developers with varied skill sets and development experience.

It is quite a risk to hire developers from such a platform, as poor industry knowledge and technical skills result in frequent product failures and project overruns.

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

Instead, we suggest you opt for a software development company providing financial software development services via vetted and experienced developers and dev teams.

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

A good software development company has excellent product development and communication procedures in place. Most importantly, they should offer you access to a range of skilled developers, each an expert in a particular software development domain.

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 is contact suitable software development companies, discuss the banking software project details with them, review their developers for their banking software development services, and start working with the best-suited remote software development partners.

  3. Room library simplifies storage and retrieval of banking app data according to user’s preferences, account details, etc. It provides an abstraction layer over SQLite and makes it easier for developers to work with local databases.

Android app developers should be skilled in testing tools like Espresso to thoroughly test functional and non-functional requirements before app deployment.

  • Secure Software development

As banking software deals with users’ confidential personal and financial data, software security is of primary importance. Your developers should be experts in implementing the latest application security practices for an ideal banking management system.

Your developers should know 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, and your app must include them.

Your developers should be familiar with compliance-as-code to ensure that your app code complies with the correct security standards and industry regulations.

Regulatory non-compliance costs businesses nearly 15 million US dollars on average. Compliance-as-code assists businesses with policy definition, code-based configurations, change management, auditability, etc.

  • Cloud Computing

Cloud computing services in software development add flexibility and scalability to the software application infrastructure. These include infrastructure, platforms, and software tools, such as storage solutions, development environments, APIs, etc.

The advantage is that businesses no longer need to invest in physical infrastructure beyond a few laptops and a wifi connection. They do not have to spend time and money on resource deployment and maintenance.

Leading cloud services providers like Amazon Web Services and Microsoft Azure offer several forms of cloud resources, such as the following:

  1. Infrastructure as a Service (IaaS) allows developers to work virtually on their cloud provider infrastructure. For example, AWS offers a virtual server service, Amazon Elastic Compute Cloud (EC2), that allows users to provide and manage virtual machines with complete control over the operating system, networking, and storage configurations.
  2. Platform as a Service (PaaS) provides operating system services that allow the management of applications and data storage in the cloud. For example, AWS Beanstalk is a fully managed service that streamlines the deployment and management of software applications. It supports several programming languages and IDEs and handles load balancing, application scaling, monitoring, etc.
  3. 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.
  • Latest Technologies

The use of the latest technologies helps build app functionalities that offer the best and most reliable customer experience. Some of the cutting-edge technologies your developers should have expertise in for banking software development include the following:

  • 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 useful patterns from user data and suggest the best-fit services for individual users. 

AI-powered chatbots are popular in banking applications to assist customers effectively. Chatbots serve multiple users simultaneously, 24/7, without ever getting tired. AI algorithms help improve chatbot-user interaction through techniques like Natural Language Processing (NLP).

NLP allows chatbots to understand human conversation, sense emotions, and generate human-like accurate responses. Latest NLP tools like ChatGPT are increasingly getting popular for integrating conversational interfaces into apps for enhanced customer support.

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

For example, Microsoft Bot Framework has several features to build, deploy, and manage chatbots, and a few of these are as follows:

  1. Your developers could use Bot Builder SDK that supports several programming languages like JavaScript, Python, and C#. It handles tasks like message processing, dialogue management, etc.

In the software industry, the most widely used is the Agile methodology. It 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 implement agile practices in the software development process. For example, the Scrum framework offers the following features:

  1. Scrum offer time-boxed development iterations called sprints. Each sprint is one to four weeks long to complete prioritized development tasks.
  2. The product backlog consists of user stories, features, and enhancements representing product requirements based on priority.
  3. At the start of every sprint, the scrum team conducts sprint planning to select items from the product backlog to work on during the sprint.
  4. The team conducts a daily standup to discuss progress and any blocks the team is facing. The team presents the work done during the sprint review meeting at the end of the sprint and gathers feedback from the product stakeholders.

These and other scrum features encourage transparency, agility, and flexibility during software development. The development team can readily adapt to changing requirements and deliver high-quality software by continuously improving the software product and team performance.
