Understanding fintech app development: What businesses need to know

Fintech apps are apps that are used for financial services, including sending & receiving funds, making payments, and assessing financial accounts. They have revolutionized the way people manage their money by giving them an accessible solution that's available on their smartphones. A remote developer can create many types of fintech apps, with the most common ones being:
- Banking apps: Often relying on artificial intelligence (AI), banking and neobanking apps like Revolut provide banking-like services without having to visit a physical branch.
- Payment solutions: Mobile payment systems like Venmo let you send and receive money internationally and locally.
- Lending platforms: Platforms like Prosper have flexible loan terms and are used when needing a faster loan approval.
- Investment tools: Platforms like Robinhood provide the tools necessary for trading investment vehicles like stocks and crypto.
- Personal finance management: Mint and YNAB are the finest examples of personal finance management fintech apps, which are used to help people track expenses, create budgets, and give insights into spending habits.
Fintech apps developed with the help of the finest mobile app development services can be used by anyone, as their functionalities benefit both regular people and financial institutions. Businesses, in particular, can greatly profit from launching fintech apps, which can have a positive effect on automation, cost savings, and enhanced user experience.
Key challenges businesses face when developing fintech apps
Fintech mobile app development is anything but simple. The fintech industry is full of hurdles for experienced fintech mobile app developers to overcome, and they include:
- Regulatory compliance: To avoid legal issues, money laundering, and terrorist financing, which arise when fintech apps don't comply with strict regulations like GDPR, PSD2, and KYC/AML, every fintech app development company must pay utmost importance to regulatory compliance.
- Security threats: Since fintech apps deal with the most sensitive financial data, they are at a constant risk of data breaches, fraud, and hacking. Thus, all fintech software development services must focus on some good practices, like data encryption, biometric security, and regular vulnerability assessments.
- Complex integrations: Due to the ever-present need to connect with banking APIs and payment processors, fintech app development services must facilitate complex integrations. These integrations allow fintech apps to access a wide range of financial services, extending their product offerings and earning users' trust.
- Scalability: An average financial app has to process a large volume of transactions at once. When outsourcing software development to a fintech app development company, it's imperative to entrust a partner that adopts agile project management methodologies and automates processes and systems.
- User trust: User trust is built once a consumer is met with a seamless and secure financial transaction. To ensure that happens, fintech app development companies have to be on constant lookout for any app vulnerabilities, the smallest of which can lead to trust issues.

Luckily, companies that can successfully surpass all of these challenges can be found after a bit of research. One such company is Empat, which develops premier apps for financial institutions. Their host of services, which ranges from fintech development to staff augmentation, can provide a business with full-fledged support and assistance.
Essential features every fintech app should have
All successful fintech apps have similar, if not the same, features. The following features impact everything from security to usability:
Secure authentication
Any threats to user data and security breaches can be very expensive for customers and companies alike. That's why every fintech app development company must put in place robust security measures, like biometric login, two-factor authentication, and encryption, protecting user data from theft.
Seamless payment processing
Cross-border transactions are no longer a hassle due to products developed in the fintech industry. Seamless payment processing not only optimizes international payment processes but it also improves profitability. Businesses and users are met with low transaction fees and minimized conversion costs, allowing for a truly seamless experience.
AI-powered fraud detection
Artificial intelligence is a handy tool not only in SaaS development but also in fintech app creation. AI and machine learning algorithms can detect suspicious and fraudulent activity, putting a stop to questionable transactions. It also helps businesses understand different types of fraud and provides them with strategies that help avoid them.
Compliance automation
When outsourcing software development to a fintech app development company, it's essential to insist on automating as many processes as possible. Automation helps fintech apps streamline business operations and reduce human error, enhancing the accuracy of compliance processes, which consists of built-in KYC and AML features.
Personalized user experience
High levels of personalization significantly boost customer engagement and loyalty. Customers value a tailored fintech app that meets their unique needs and provides AI-driven insights and financial recommendations.

Multi-currency support
International transactions come with a plethora of challenges, some of which can cause customers to abandon their carts. The disparity between local and foreign currency can sometimes be too great, causing a lot of confusion for the customers. With a mobile app that employs the latest financial technology trends, international transactions are no longer a problem. Multi-currency support ensures you know the exact amount you have to pay in your local currency, which is why it's an important feature that outsourced web development pros always include in the app development process.
Blockchain integration
There's an ongoing exploration of crypto and blockchain technology in the financial industry. They are developing at a fast pace, promising security and transparency with every transaction. Blockchain transactions are visible to authorized participants, so you'll have a clear audit trail.
The fintech app development process: from idea to launch
Whether developing a mobile banking app or a personal financial management tool, the development team has a lot of work in front of them. The process of developing a fintech app can be broken down into 5 steps.
Step 1 - Defining the business model and compliance strategy
Whether working with React Native developers or back-end engineers, the first step is always the same – brainstorming. Businesses need to decide what type of fintech app they want to develop, as their choices range from digital wallets to robo-advisors. A skilled development team can help you decide what type of mobile app would best suit your business values and needs, providing unmatched support during the most crucial stage of app development.

If you already have a target audience and a market you want to penetrate, partnering with a qualified financial technology development team will be your best bet. It will equip you with a compliance expert who will ensure your mobile app meets all important legal and financial security standards.
Step 2 - Planning the app architecture and choosing the right tech stack
If you've partnered with a fintech software development company, this is where their assistance becomes imperative. With your chosen development partner, you'll be tasked with planning the app architecture and deciding on the right tech stack for your business.
The first decision boils down to cloud-based vs. on-premise infrastructure. On-premise infrastructure is hosted on your company's hardware infrastructure, giving you more control but also requiring more work. Cloud-based infrastructure relies on a provider's server and is accessed using the web, coming with unmatched security and requiring no effort on your part.
Next up, have your fintech app development company help you choose the right programming languages and frameworks for your business. Do you want to build your financial app with the help of Java developers? Do you want to have Django developers use one of the best Python frameworks to deliver excellence in the fintech sphere? Make this decision with your chosen fintech app development company, and you are guaranteed to pick wisely.
Finally, have your fintech app developer help you ensure compatibility with banking APIs and third-party integrations. Skilled full-stack developers thoroughly understand the requirements and specifications of both your product and the third-party services you want to integrate. Therefore, they can help you consider all the important risks and dependencies before making any decisions.
Step 3 - UX/UI design for a seamless customer experience
The design and user-friendliness of the financial app are among the main things that motivate us to keep using it. People want to finish their transactions with a few taps on the screen. That's why hiring a graphic designer who will incorporate accessibility features for different user needs is one of the things businesses should do. These include built-in chatbots and customizable dashboards.

Another thing that can skyrocket user experience is intuitive navigation. Whether you hire a full-stack developer or a dedicated UX/UI designer, the goal will be to design clear, consistent, and user-friendly navigation that meets users' expectations. The cherry on top will be working with a developer who will apply security principles and best practices while designing for both security and usability.
Step 4 - Developing and testing security protocols
Whenever you are outstaffing IT services, you want to ensure you hire a professional with ample knowledge in advanced encryption and data protection. Your fintech app development company should be tasked with developing and testing security protocols, which serve as a way to identify and mitigate potential vulnerabilities in software systems. More importantly, financial app developers will want to focus on:
- Penetration testing – an authorized simulated cyberattack that evaluates the security of a system
- Vulnerability scanning – a computer program that searches for known weaknesses
- Code reviews – a peer review of a code that ensures it meets the standards
The finest back-end and front-end developers in the fintech sector will go one step further to ensure that safety is at the highest level by leveraging AI. Through the recognition of patterns, anomaly identification, and data verification, AI can help monitor for fraud detection and minimize the chances of anything going wrong.
Step 5 - Launching, monitoring, and scaling the app
Once security, web design, and web development have been completed, it's time to launch the app. Before full deployment of your FinTech application, it's necessary to test it with real users. Release the app to a select group of users and gather their feedback, which you can use to fine-tune your fintech application. Once you apply the appropriate fintech solutions, you are ready to officially launch the app.
The job is nowhere near done as monitoring enters the scene. It's necessary to track the performance of your fintech app by setting up real-time monitoring tools. They will warn you of any potential problems with your app, giving web designers and back-end developers sufficient time to resolve them.
Remember – regardless of how large-scale your app is today, there's always room for improvement. That's why you need to plan for scalability ahead of time, which is best done with the help of a financial app development company. Your partner can help you monitor for feature updates and make scaling decisions, such as estimating whether you need to consider switching to React.js from another library.
Why businesses should work with a fintech app development company
There's no need to try and be a hero by developing a fintech app in-house – especially since you can find a budget-friendly web developer who will ensure your app meets all the important criteria. This includes:
- Expertise in regulatory compliance: The fintech industry probably has the strictest legal and security standards in place, as it deals with people's money. Hiring developers for your business who can ensure your app meets all regulatory compliance is a mandatory first step.
- Advanced security measures: Unlike professional teams, who have experience with high-level encryption, fraud detection, and risk management, your in-house team probably lags behind. Your chosen team will exploit application vulnerabilities and address any flaws discovered.
- Seamless API integrations: Integrating your app with APIs is among the most complex aspects of fintech app development. With Fintech app development services, you'll have banking connections, payment processing, and blockchain integration handled by a professional team.
- Faster time to market: Developing a fintech app takes time – too much time if handled by an inexperienced team. Fintech app development companies know how to streamline processes so that your app reaches the target audience quickly and at the optimal price.
- Ongoing support and maintenance: Launching the app doesn't mark the end of the process. Many companies, like Empat, offer at least one month of free project support and bug fixes, ensuring your app is always updated and glitch-free.
