The Growth of the Fintech Market and Digital Banking Industry

The fintech sector has seen more twists and turns than a prime-time soap opera, and with the same level of drama. Here are some snippets of numerous banking software development and general fintech industry twists.

A Timeline of the Fintech Explosion

  • 2008. The Global financial crisis. Traditional banks lost the ground and fintech startups got their heads up, looking to capitalize on the overall confusion and bring innovation.
  • 2013. Bitcoin’s price gets to $1,000 for the first time, starting the good, the bad and the ugly of the cryptocurrencies and blockchain technology era. Suddenly, everyone and their grandma wanted in on “magic Internet money.”
  • 2015. China’s Ant Financial, the behemoth behind Alipay, reaches $45 billion value. West gets reminded once again that fintech is not just a buzzword, it’s a lucrative industry. And it’s time to move fast. 
  • 2018. Global fintech investments double to a whopping $55 billion. Everyone wanted a slice of the fintech pie.
  • 2019. Digital-only banks like Revolut, Monzo, and N26 start gaining traction. They operate without any brick-and-mortar branches and challenge the big traditional banks with their user-friendly services and low fees.
  • 2020. The COVID-19 pandemic forces everyone online. Digital payments and neobanking see a massive boost as people avoid physical contact. Fintech solutions go from being a nice-to-have to essential.
  • 2021. Decentralized finance or DeFi takes off. Platforms that let people lend, borrow, or trade without middlemen grow popular. By year-end, DeFi has over $40 billion in assets, showing the world that blockchain’s potential goes beyond just cryptocurrencies.
  • 2022. Fintech booms in places like India, Brazil, and Nigeria. New startups and apps pop up, giving many people their first taste of modern financial services, bridging the gap left by traditional banks.
  • 2023. Governments and institutions worldwide start setting rules for fintech to make sure it’s safe but still innovative. The world starts seeing fintech not just as a trend, but as the new norm in finance.

And here we are, strategizing about banking software you want to develop that hopefully will disrupt the market and make such a list in a few years. What should it get rid of not to bring the cons of traditional banks into the new world? Let’s see.

What Was/Is Wrong with Traditional Banks?

  • Legacy systems. While fintechs were built for the digital age, many banks still relied on technology that was older than the first “Die Hard.” Some of them still are.
  • Risk aversion. Banks, with their stringent regulations and conservative nature, often ignore innovation. In the effort to increase security, they also don’t invest in state-of-the-art sec systems and quality tests, jeopardizing account safety.
  • UX. If banking apps were rated on user-friendliness, some apps rolled out by traditional banks would rank just above “trying to assemble IKEA furniture blindfolded.” In contrast, modern fintech solutions are designed from scratch with the user in mind, prioritizing seamless experiences over bureaucratic hurdles.

Truth to say, big legacy financial institutions catch up rather fast. They cannot act fully like startups and smaller companies, but they successfully incorporate some of the approaches to their benefit:
 

Bruce

“A larger organization that understands its processes and systems can make more significant releases. For example, a big legacy bank wants fintech to engage more with users. They know how the system works; it is just a question of putting a user-friendly Front-End on.

While a startup — new and fresh, something no one has seen before, needs constant checks on where and how to evolve. Big financial players use MVP to show what is going on, and startups use MVP to learn and define where they are going.”

Bruce Mason, Delivery and UK Director in QArea 

In essence, while traditional banks were busy fumbling with outdated tech and red tape, fintechs were sprinting ahead, capitalizing on modern tech and changing consumer expectations. It’s like comparing a horse-drawn carriage to a Tesla. And we all know who wins that race.

And now let’s talk numbers, and how these numbers can reward those investing in quality and innovative banking software solution. 

  • Operational efficiency and savings. As banks benefit from custom software development, operational costs are taking a nosedive. For example, a digital transaction costs a fraction of its physical counterpart. JPMorgan Chase and Oliver Wyman reported that central bank digital currencies (CBDCs) could cut company transaction costs by almost $100 billion annually.
  • Revenue growth and new opportunities. Goldman Sachs’ digital bank, Marcus, is a testament to the revenue possibilities. Within its initial 18 months, Marcus secured over $50 billion in deposits. When traditional banks choose to benefit from a software product, they could unlock untapped revenue streams.
  • Customer base expansion. The global fintech adoption rate, according to EY, leaped from 16% in 2015 to 64% in 2019. For banks, this implies an expanding customer base, only if they can offer the seamless digital experience these users seek.
  • Mitigated risks and improved returns. AI and data analytics aren’t just buzzwords. They offer banks a smarter way to assess risks. A study by Autonomous Research highlighted that banks could leverage AI to save up to $1 trillion by 2030 through improved efficiency and reduced risks.

These are inspiring examples of how financial institutions can benefit from innovative app development — be it a mobile banking application, document management software or any other digital banking service you want to launch. 

It seems a good moment to discuss different types of banking software applications, so let’s have at it.

When planning or updating banking software, there are key features that financial institutions and software development companies must consider ensuring efficiency, user satisfaction, and a competitive edge. Let’s explore the most impactful ones.

Digital Onboarding financial software

Enabling customers to open an account, secure a loan, or embark on investments without visiting a bank branch is not just a luxury; it’s the new standard. This feature enhances user convenience, significantly boosting user sign-ups. But it’s not only about customer convenience. Banks can also significantly reduce their operational costs. To achieve this, integration with identity verification tools, top-notch data encryption, and streamlined digital KYC processes are crucial. Realizing this vision requires a dedicated team of developers, UX/UI designers, and a security expert, dedicating approximately 3–4 months to ensure everything works seamlessly.

Mobile Wallet Integration

With mobile wallet integration, users can effortlessly store virtual money, make a tap-to-pay purchase, or send money on the go. It’s a feature that can boost transaction rates and keep users coming back. Achieving this involves weaving in NFC technology, QR code capabilities, and syncing up with reliable third-party payment gateways. Crafting such a feature takes the combined skills of mobile app developers, payment gateway specialists, and security experts, with a timeline settling around 4–5 months to get it just right.

AI-Powered Financial Advisory

AI-powered financial advisory systems tailor advice to each user, making sense of their behaviors and the broader market trends. It’s not just about nudging users to invest; it’s about earning their trust, guiding them towards sound financial decisions, and in turn, driving up the bank’s revenues. Bringing this feature to life means melding machine learning models with data analytics tools and tapping into real-time market data through APIs. It’s a collaborative dance between data scientists, backend developers, and financial analysts, and the entire choreography can take a span of around 5–6 months to perfect.

Real-time Notifications and Alerts

With real-time notifications and alerts, users stay updated on their account activities, get the latest financial news, and catch wind of special offers. It’s not just about keeping them informed; it’s a way to drive app engagement, uphold transparency, and open doors for selling more services. Crafting this feature requires a concoction of in-app notification systems, SMS gateways, and email alert mechanisms. The team behind this magic? Mobile and web developers teamed up with integration whizzes. And the best part? It might just take a swift 2-3 months to get everything up and running.

Biometric Security Enhancements

With biometric security enhancements, banking apps elevate their safety game. Users can utilize their unique fingerprint, facial features, or even voice patterns to ensure unauthorized access is a thing of the past. It’s a significant step that not only amplifies user trust, but actively combats fraudulent activities. The tech trick? Seamlessly integrating biometric SDKs and APIs into existing mobile apps or web platforms. Pulling this off usually involves a collaboration between security buffs and dedicated mobile banking app developers, with a timeline stretching around 3 – 4 months.

P2P Lending Platform

P2P lending platforms allow users can lend or borrow money directly from their peers. This isn’t just a fancy feature; it’s a gateway to an entirely new revenue stream, offering banks a chance to diversify their portfolio offerings. But it’s not as simple as it sounds. A sturdy foundation requires the development of a sharp matching algorithm, an intelligent credit scoring system, and a fortress-like transaction platform. Who’s behind this marvel? A versatile team of developers, sharp-eyed financial analysts, and those ever-so-crucial security experts. The journey to launch? A substantial 6–8 months, but the results are worth the wait.

The Importance of UI/UX in Banking Application Development

Imagine walking into a bank — the walls are drab, the layout confusing, and you can’t quite figure out where the counter is. That’s the physical equivalent of a poorly designed banking software. In contrast, an inviting space with clear signage, a friendly atmosphere, and efficient service would not only make your experience pleasant but also ensure you’re more likely to return. The same principles apply to banking software.

Why It Matters

The heart of UX design in banking lies in its potential to create smooth interactions between users and their financial tools. A thoughtfully designed interface can be the difference between a user sticking around or switching to a competitor. The true essence of UX design extends beyond aesthetics. It encompasses usability, visual appeal, interaction dynamics, and information flow. When done right, it fosters trust and loyalty, boosting a bank’s revenue and customer base.

Covering Customer Needs

Digital banking has morphed from a luxury to a necessity. Today’s users expect their banking software to be intuitive, personalized, and above all, secure.

  1. Easy Navigation. Simplicity is the key. A clean, straightforward design ensures users can carry out tasks effortlessly.
  2. Personal Touch. Using data analytics, banks can offer tailored suggestions, nudging customers towards relevant services and opportunities.
  3. Uncompromised Security. Given the sensitive nature of banking, robust security measures are non-negotiable.

To design a compelling banking platform and offer excellent services to customers, it’s crucial to first understand your users. Preliminary research, combined with client interviews, can reveal invaluable insights. And once a design is proposed, rigorous testing is essential to refine and perfect the interface.

A Nod to Inclusivity

Modern banking is for everyone. Thus, ensuring digital platforms cater to a diverse user base, including the differently abled and the elderly, isn’t just a social responsibility—it’s a business imperative. Innovations like talking ATMs and screen readers help realize this commitment. Make sure that when you come up with custom banking software idea, you don’t only think about generalized “middle class, able, tech proficient male/female,” because such “personas” don’t work anymore. 

Quick Take on Stages of Finance Software Development

Just as a bank wouldn’t function without a structured system, a well-thought-out plan is crucial for creating effective banking software. Let’s journey through the stages involved in banking software and mobile banking app development:

  1. Requirement Analysis. This foundational stage is all about understanding the unique needs of the banking environment. Software developers, stakeholders, and potential users converge to discuss the software’s objectives, intended banking functions, and the financial challenges it aims to address. It answers the “What?” and “Why?” of the banking software project.
  2. Planning. Equipped with the requirements, the next step is to outline the “How?”. This is the phase where timelines are set, resources identified, and budgets allocated. It’s a strategic juncture where the feasibility of the banking software is evaluated.
  3. Design. Think of this as sketching the blueprint for a bank’s digital interface. Based on the requirements, a prototype is crafted detailing how the software or mobile banking app will look and operate. This stage prioritizes user interface (UI) and user experience (UX) to guarantee a seamless banking experience.
  4. Development. Software developers dive deep into coding, using various programming languages and tools to develop the banking software, ensuring it meets the complex and secure demands of the financial sector.
  5. Testing. Banking software, given its critical nature, undergoes rigorous testing. Every feature is checked for bugs, errors, or inconsistencies. It’s imperative that the software performs impeccably, especially when handling sensitive financial data.

One of the common challenges in Fintech QA projects is uncertainty. Priorities shift, requirements change, delays occur and as a result the agreed QA schedule gets affected. A way to counter this is assigning additional resources at the onboarding phase of a project, so you have a couple of “extra” QAs. They can switch to other projects once the onboarding is done. But if someone from the “core” team goes on a vacation or the workload increases drastically, they can return and save the day.”

  1. Deployment. Once thoroughly tested, the software is launched for banking customers. It might be introduced as a mobile banking app available for download, a web platform, or integrated into existing banking systems.
  2. Maintenance. Regular updates, tweaks, and enhancements are necessary to keep the software or mobile banking app attuned to changing financial regulations, user preferences, and technological advancements.

Costing and Budgeting for Banking Software Development: A Comprehensive Insight

Developing banking software is an investment in digital infrastructure, enhancing service delivery, user experience, and competitive positioning. Understanding the cost implications is crucial to align the project with budgetary constraints while ensuring functionality and security. Let’s delve into the financial side of banking software development.

Factors Affecting Development Costs

  • Complexity. The broader the functionality spectrum, the higher the costs. Basic mobile banking apps will be less expensive than a comprehensive online banking system with advanced features like AI-driven financial advisory or biometric security.
  • Team’s geographical location. Developer rates can vary significantly based on their location. For instance, in the US, a software developer might charge between $100 and $150 per hour. In contrast, Eastern European developers offer competitive rates ranging from $30 to $50 per hour.
  • Development time. If you cram too many features even at the MVP stage, the development coast will seriously inflate. If you choose an experienced banking software development company, they will guide you through and help balance the number of features with the budget you have.
  • Security requirements. Banking apps demand robust security, and it may be rather costIy, but non-negotiable considering all the domain regulations.
  • Integration with existing systems. Often, it is cheaper to create a bigger, more complex software from scratch than to connect a smaller app with  with legacy banking systems. Layers of complexity also add costs.
  • Maintenance and updates. Post-launch costs for maintenance, updates, and potential scalability should be factored into the total budget.

Approximate Prices for Specific Features

  • Basic mobile banking app. A simple app with standard features (account overview, transaction history, transfers) might cost between $50,000 (Eastern Europe) to $200,000 (US).
  • Biometric security enhancements. Implementing fingerprint or facial recognition could add anywhere from $10,000 (Eastern Europe) to $40,000 (US) to your total cost.
  • AI-Powered financial advisory. Integrating AI algorithms and tools can push the cost by an additional $20,000 (Eastern Europe) to $80,000 (US).
  • Real-time notifications and alerts. This feature could add $5,000 (Eastern Europe) to $20,000 (US).

(Note: These are rough estimates and can vary based on the project’s specific requirements. We have a big and detailed article on developemnt costs, you should check it out.)

Considerations for Budgeting and Cost-saving

  • Prioritize features. Not all features need to be rolled out in version 1.0. Prioritize essential features and gradually introduce others in subsequent updates.
  • Outsource strategically. Consider leveraging the expertise of developers in regions like Eastern Europe, which offers a blend of skill and cost-effectiveness.
  • Use open-source tools. There are numerous reliable open-source tools available that can reduce development costs without compromising quality.
  • Rely on iterative development. Adopting methodologies like Agile can help in releasing MVP (Minimum Viable Product) versions, gathering user feedback, and making informed financial decisions on future iterations.
  • Check on QA Testing in Eastern Europe. QA (Quality Assurance) testing is pivotal. Given the cost-effectiveness of Eastern European QA testers, who might charge between $20 and $35 per hour, this could be a strategic move to ensure quality while managing costs.

Final Thoughts on Banking Software Development Strategy

Banking and technology have grown hand in hand, reshaping how we handle money in the digital age. At its core, the success of modern banking software lies in understanding the user. It’s about making apps and platforms that are easy, enjoyable, and secure to use.

The blend of the right features, technology, and a solid development plan is the recipe for success. But always remember, amidst all the tech talk, the human touch matters most. As we venture forward, let’s prioritize the people we serve and the experiences we aim to provide. It’s not just about banking smarter; it’s about banking with heart.
