What kinds of software are used in banks?

Multiple kinds of banking software are present in a bank. Let us discuss the main ones.

  • Software for managing the financial operations and transactions
  • Document management software
  • Administrative management software
  • Customer service solutions

Types of banking software

Software to manage financial operations

Software for managing the financial operations and transactions consists of the following features

  • Management accounting
  • Balanced scorecard system
  • Management of consolidated financial statements
  • Transfer management of financial resources
  • Financial planning and budgeting

The software that manages the financial operations and transactions provides operational control to the bank authorities. These software also provides a wide array of financial management tools that help the bank authorities in processes like planning, budgeting, and management accounting. Such software provides a high level of transparency in the overall banking system and helps the managers get a coordinated response from all the stakeholders.

Document management software

Document management software significantly reduces the paperwork of bank executives. To ease the process of document management, banks use document management software. Banking document management software allows bank management to free up human resources by automating the tedious process of banking document management.

The software can automate all the processes associated with the compilation of memos, administrative reports, loan papers, customer KYC documents, etc. Banking documentation software drastically reduces the time spent on paperwork. Many banks provide their customers with the ease of uploading their documents from their mobile banking app.

Administrative management software

The administrative management software in a banking institution helps the managers manage the bank better. The software is concerned with the overall administration of the bank, which includes the following areas

  • Sales management
  • Materials management
  • Purchase management
  • Accounting
  • Budgeting
  • Cost control
  • Personnel management
  • Payroll management

Robust administrative management software boosts the administrative efficiency of the banking system. The enhanced administrative efficiency helps the bank save countless hours which translates into savings in dollar terms. The managers can focus on high-priority projects as the administrative software saves time by taking care of the low-priority ones.

Customer service solutions

The CRM of a banking system is a combination of modules that ensures the smooth interaction of the banking system with the customers. The banking CRM systems typically include the following modules

  • Marketing module
  • Banking automation module
  • Customer background information module

The CRM of a banking system covers all the stages of the interaction right from attracting the customers to banking to after-sales service. The CRM systems help to easily interact with the customers, identify their pain points, and suggest measures to improve the communication process based on this analysis. CRM systems help the bank deliver personalized service to its clients, which helps boost customer engagement levels. Talking about user engagement, we think you would love to know how mobile banking apps can help elevate the user experience.

The full-fledged banking software can be used by the banks for their internal purposes. Nevertheless, mobile banking software can be developed customized to their customers. The mobile banking application is quicker and provides all banking services to the user on the go. For instance, a user can transfer money, check balance, apply for a new checkbook, and avail services they like.

Top trends in banking software development

Like every industry, the banking and financial services industry is also going through disruptive changes. Technological innovations will shape the future of the banking industry. We have listed below some of the major trends that will disrupt the banking industry in the near future.

Contactless payments

A rising trend in the banking sector is that of contactless payment. With micro-chip-enabled credit cards, the customers do not need to go through the hassle of remembering the passcode and entering it every time they want to pay. Banking software will need to upgrade itself to provide the back-end for contactless payments. To provide contactless payments, the banking software will need to update the balance in real-time without compromising on the security of the transaction.

Machine learning

The BFSI (banking and financial services industry) has been at the forefront of adopting digital technologies like Machine Learning. There are many ML-based technologies already in use in the banking sector. The ACD (Alternative Credit Decision-Making System) utilizes the power of ML to help bank executives take correct decisions regarding loan disbursals.

Sophisticated ML algorithms collect and analyze customers’ data to predict their needs and provide the customers with the correct products at the correct time. Intelligent chatbots are deployed by many banks to solve the queries of their customers 24×7. ML algorithms alert the concerned authorities when they diverge from normal customer transaction behavior saving security breaches. Research suggests that ML and other AI technologies in banking will help banks trillion in operating costs by 2030 save $1 trillion in operating costs by 2030.


Blockchain adoption has picked up speed in recent times. The global Blockchain market is estimated to generate revenue of more than $20 billion by 2024. In the banking system, there are a lot of middlemen involved in every transaction. These middlemen not only charge money, they also make the process slow.

Blockchain is a decentralized and secure technology that eliminates these middlemen and makes the process faster and cheaper. Blockchain stores data about every transaction right from its moment of inception and provides water-tight security to the data. It is impossible to modify or forge previous data entries. The transparency and added security that Blockchain provides help banks with auditing and accounting.


Financial transactions demand security and what better way to provide security from unauthorized transactions than to link these transactions with biometrics? Since Apple included fingerprint authentication into iPhones, many banks all over the world integrated fingerprint authentication into their banking systems.

Apart from fingerprint sensors, other biometric technologies like retina scanners, voice pattern scans, and face scans are also rising. Many mobile banking applications provide log-in options through biometrics. This helps the users quickly register or log in to the portal and avail banking services.

Steps to develop secure banking software

Steps to develop secure banking software

The steps of building banking software are more or less similar to the steps of building any software or mobile app. Let us have a look at the various steps involved in building banking software

Step 1: Define the purpose

Not just for banking software or mobile banking app but one needs to have a definite purpose before building any kind of software. Before starting work on building a banking application, the developers must ask the following questions

  • What are the problems that the banking software intends to solve?
  • Which are the features that will prove to be the USP of the banking app?
  • Will the banking software or mobile banking applications require any specialized technology to run?
  • Is it intended to be used as an internal banking system or will the bank’s customers also have access to the online banking portal?
  • How will developing a banking application benefit the bank?
  • Which kind of software will it be, a CRM, core banking software or loan management software?

Once the purpose is established, the banking software developers proceed towards the next step, research, and feasibility analysis.

Step 2: Research and feasibility analysis

The developers start by conducting thorough market research. The research includes finding the existing examples of the product that they want to build.

Once the preliminary research is over, the application developers proceed towards conducting a feasibility analysis. The feasibility analysis ascertains whether it makes sense to move ahead with the project or not. Feasibility analysis can also help the developers remove unnecessary things from the project.

While conducting feasibility analysis, the developers must analyze the following 4 elements

Technical feasibility

Before proceeding with the project, the developers must conduct a technical feasibility analysis of the project. The technical feasibility analysis checks whether the necessary technical resources are available for the mobile banking project or not.

Financial feasibility

Financial feasibility analysis analyzes whether it makes financial sense to develop the software. A thorough cost-benefit analysis will enable the developers to estimate the financial viability of the project accurately. This is the stage where unnecessary things like extra features in banking mobile applications or banking software can be eliminated.


This is the stage of feasibility analysis where the developers analyze whether the project can be completed within the stipulated period or not. The developers break down each development stage and analyze the time required to complete each stage in this stage.


This stage focuses on the operational aspects of the project like maintenance, the team required, support to be provided after the development is complete, and so on.

The developers must conduct extensive research and feasibility analysis before moving ahead with the banking software project. This is when the developers must collect as much data as possible and thoroughly analyze the four elements.

Step 3: Platform selection

Once the first two steps are complete, the developers would have had a fair bit of idea about their goal and the project’s feasibility. In the third step, the developers need to select the best platform for their software. Mobile banking application software requires a secure platform to prevent fraudulent transactions and malware attacks.

While selecting the platform, the developers must ensure that the selected platform corresponds to the requirements and goals in the best way. Once the platform is selected, the next decision to make is to select the technology stack for banking software solutions

Step 4: Select the technology stack

In this stage, the tech experts select the appropriate programming languages, database systems, and frameworks according to the banking software to be developed. Technology experts select the technology stack according to the purpose and utilization of the software and the kind of end-user they are catering to.

For instance, digital banking applications would utilize technologies like PHP, MySQL, C, and C++. The developers must ensure that the technologies that they select are the most appropriate ones for their banking app development projects.

Step 5: Create a Technical Specification

Creating a technical specification document for the banking software is the next step in the process. The technical specification document is a detailed technical description of the required banking app. The document tries to list the goals of a project, its milestones, the vital elements, and other essential details of the project in one place.

For banking mobile solutions, the first thing to write in a technical specification document would be a summary. The summary is similar to writing an abstract in an academic paper which summarizes the entire paper. The summary is written first so that anyone reading the technical specification document doesn’t need to go through the entire paper to get the gist of the matter.

The summary provides the following information to the reader

  • The goal of the project
  • Key stakeholders
  • Deadline
  • Technical details

Once the summary is complete, the next step would be to add the background information. This section talks about why the project was initiated in the first place and describes the key concept of the project. The next step would be to provide a detailed working plan for the project.

Step 6: Set the budget

While preparing the budget, the developers must bear in mind that developing financial software usually costs more as the software is complex and it takes a lot of time and effort on the part of the developers. Mobile banking app solutions are comparatively larger in size and complexity; hence the cost of developing banking software could be a bit high.

Banks must make sure that the budget they keep is attractive enough for leading banking software developers to quote. It is difficult for banks to estimate the budget required to build banking software correctly. It is best to consult a professional software development team with the requirements to have a more accurate insight into the budget.

While setting the budget, it is important to note that the initial estimate is just approximate. At times when the project is quite a large one, the final budget may differ a little from the initial estimate. So it is better to have a margin of safety in the budget. The margin of safety can be anywhere between 10-20% of the budget. This is just to ensure that the businesses have all the required features integrated based on the trends to withstand the competition and grow better.

Once the budget is planned, it is time to move to the last step, finding the best banking software developers.

Step 7: Selecting the best developers

Picking the wrong banking software development company can prove to be a disaster for the project. Incompetent software developers will waste a lot of time and money and deliver lousy software, which will ultimately ruin the reputation of the bank.

The following things will aid a bank to select the best software developers from the software development service providing company and build their own software and mobile development team

  • Experience
  • Technical expertise

Previous Experience

Banking is a high-stakes industry as even a small mistake can blow out of proportion and harm the business of the bank. This is why it can prove risky to hire software developers who haven’t worked on a similar project.

Before giving the project, the banks must assess whether the software developers have successfully delivered such a huge software in the past and which industries have they developed the apps for and it will be better if they have similar experience in building an online banking solution.

Technical expertise

The technical skills of the software development company must match the technology stack required to build the particular banking software.

For instance, if the banking software demands expertise in C++, then there is no point in working with a company that doesn’t have experienced C++ developers. Likewise, mobile banking solutions would require native (Android or iOS developers) or cross-platform developers.

How much does it cost for banking software?

Cost to Develop a Banking App

Now that we have a look at the things to consider while selecting the best banking software development company, let’s have a glance at the cost of developing banking software.

The cost of building banking software depends on two major factors

Number and complexity of features

The cost of mobile banking software development with basic features will be much less than the cost of banking software with lots of advanced features.

For instance, the cost of developing internal banking software which will be used only by the bank’s employees and has only a few basic features like generating reports, and logging attendance of the banking employees will be less.

While the cost of developing a retail customer-facing banking software, that allows the bank’s customers to access their bank accounts digitally and perform actions like opening a bank account and conducting transactions, would be much higher. As the number and level of features rise, so does the cost.

The location of the software developers

The location of the software developers also has an overbearing effect on the cost of developing banking software. Hiring a software development company from North America and Europe can prove to be 5-6 times more expensive than hiring one from India. This is because of the difference in the hourly wages that these companies charge.

Depending upon the complexity of the features and the development company’s location, the cost of building a banking software development can range anywhere between $30,000- 130000

Software Development Cost Estimation

Must-have Features in a banking software

features of banking software

There are some basic features that a banking software should have based on the different types of users

  • Opening new accounts
  • Processing cash deposits and withdrawals
  • Payment clearance
  • Processing loans
  • Calculating and managing interest rate

Apart from the basic features, the banks can also consider adding the following features that can help them serve their customers in a better manner.

Advanced Security & Fraud Alerts

According to a report published by Accenture, cyber crime costs  financial institutions  around $18.3 million annually. Banking software cannot afford to be complacent with security as the problems that arise due to lapse in security can prove to be disastrous for the bank as well as its customers.

The first step to ensure robust security in the banking software is at the sign-in page. The banking software developers must ensure that the sign-in details of the customers are encrypted according to the most robust encryption standards. The sign-in process must be both fast and secure so that the users do not feel the process to be cumbersome and also have peace of mind that the process is secure.

Sophisticated AI algorithms can help banks detect fraudulent transactions in a user’s account. The AI system assesses millions of transactions and identifies a pattern. The AI algorithm then alerts the users as well as the bankers whenever it finds out a transaction that significantly deviates from the usual pattern of the user.

Should support P2P payments

Peer-to-peer or P2P payments, as they are popularly known, allow the bank’s customers to send money directly to another user’s account. The popularity of P2P payments has grown and according to a report the market for P2P payments is expected to grow till the value of 4.4 trillion by 2027. While many third-party P2P applications are available in the market like Paypal, many users would prefer the security and convenience of banking software as the bank would directly oversee the fund transfer.

Another benefit that can lure the users to do P2P payments directly with the bank is that, unlike third-party vendors, most banks do not charge hefty payment transfer fees for facilitating these payments.

Intelligent Chatbots

The growth of a bank relies on how well the bank can serve its customers. Successful banks know this and go the extra mile to provide excellent customer service with a personalized approach to their clients.

AI Chatbots can help the banks address the concerns of the customers 24×7. The Chatbots ensure that bank customers do not need to wait for long telephonic ques when they want to resolve their queries. The Chatbot will ask simple questions to the customers and based on their response, will answer their queries.

In case the Chatbot is unable to resolve the query of the customer, and then it will assign the task to a human customer care executive. The Chatbot will provide the chat history to the customer care executive who will help the executive understand the problem and save frustration for the customer as the customer won’t need to repeat the problem.

Voice-Assisted Banking

Voice-search is one of the most important trends in the tech world currently. According to a PWC report, around 7 out of 10 consumers prefer to use voice search to buy something rather than type it. Voice-assisted banking is gaining prominence in banking circles.

As more people buy smart speakers, they are warming up to the idea of voice-assisted banking. According to a poll conducted by Fiserv, the perception towards voice-assisted banking is changing among US consumers.

Voice technology is an important part of many modern-day FinTech apps and software. Many consider it to be one of the next-generation banking technologies. Financial institutions are not only using voice technology for providing security to their users, but they are also using it to enhance the customer experience.

Many banks provide voice-enabled services to their clients. Using voice-enabled technologies, the banks provide essential services like checking account balances, basic customer queries, and other simple tasks. By using voice technologies, the banks are reducing the work of human executives so that they can focus on other high-value tasks.

Track spending habits

Functionality that helps users track their spendings can prove beneficial for the banking software users also. The feature should allow the users to set saving goals.

Analytical customized charts are a great way to demonstrate the progress towards the goal. The developers should include spending on different categories in the banking software, which will help the bank’s customers track their spending on various things.

Technology Stack for banking software

While selecting the technology stack for banking software, the developers must strike a proper balance between convenience and security. Banks and financial institutions should help companies who provide banking software development services to select the most appropriate technology stack according to their requirements.

We have mentioned below a technology stack for banking software that can act as a good reference point.
