The following are the most crucial features that you must consider for top-notch FinTech application development:

• Simple and Intuitive Interface - What most consumers expect from a FinTech app is a user-friendly and compelling interface because a captivating user interface will help your app outmatch your competitors.

• Smooth Payment Gateway – When opting for custom FinTech app development, you should always consider integrating services like checking account balances, making digital payments, and transferring money. Also, prioritize your app security to provide a convenient payment gateway.

• Multi-User Support – Integrating an effective user management system in your app is essential. This feature helps employees or family members share and monitor a single account.

• Personalization and AI Algorithm Utilization - Banking applications use these features a lot. It is due to their capability to view up-to-date spending analytics, present frequently used services on the front page, transfer money by a regularly used number, and many more. Here, you can also integrate Big Data to foretell the client pattern and provide offers to target them.

• Online Chats – Integrating this feature during FinTech app development will most certainly improve your customer satisfaction rate. For most customers, online assistance is a more suitable alternative to email and phone support. Moreover, AI-powered chatbots help reduce costs and enhance the user experience by assisting clients and answering their questions 24*7.

Accordingly, your developers must maintain the accuracy and speed of this data. You can also allow your users to go through particular aspects if they want to explore and learn.

• Security – Security is tremendously essential for a FinTech app. While user data provides a more personalized and richer experience, you must integrate data security and risk management to protect your users' sensitive information. Simply, the authentication process should be both intuitive and highly secure.

Eight Essential Steps for Successful FinTech App Development

Now that you have reached this point of the article, you must be wondering how to start developing a FinTech app and what app development stages you should follow. Let's go into detail.

Suppose you're planning to develop a rental management app. Your users will be able to check potential tenants' credit scores, build and digitally sign a contract, accept security deposits, manage their release when the leasing contract ends, easily renew contacts, and so on.

In such a project, your value proposition is to increase the ROI for property owners and streamline the application process for tenants - a win-win scenario every FinTech app should aim for.

So, you need to develop multiple functionalities for this app, and if you follow the hard way, your developers need to hard-code all these functionalities one by one. The process would take a long time and a good fortune. But thankfully, you have APIs for each of these functionalities that make the FinTech app design process much more manageable.

Step 1: Manage and Authenticate Users

Your weapon to manage and authenticate users is Firebase. Look at this tool as the skeleton of your app to place the organs and muscle-like functionalities. Additionally, Firebase offers crash reporting, user management, and authentication. You can integrate a host of Google services with it to provide a fantastic app experience to your users.

Step 2: Implement Secure Hosting

The engine room of your FinTech app would be Cloud Firestore. It's a Firebase product that works as an encrypted solution of a cloud-hosted database. You can integrate with other Firebase products for rich user experience and efficient app development. Besides, Cloud Firestore simplifies the development, enables optimized performance, and has automated scaling.

Step 3: Incorporate Credit Score Checking

Universal Credit Services offers a Credit Report API that obtains data from 3 credit bureaus (Experian, Equifax, and TransUnion) and generates single-unified credit reports for users. Your app can also support bulk requests with the help of this API.

The UCS API enables customers to access the following data:

• SSA-89
• Decision-only credit reports
• 4506-T IRS TAX transcripts
• Credit records before employment
• Social security number authentication
• Eviction searches
• Criminal searches
• Motor vehicle reports

You can also use a consumer-facing API from Experian to generate credit reports and scores. Your customers can also share their reports with third parties online. Lastly, American Credit Systems (ACS) allows you to create full public records, FICO scores, credit reports, and credit inquiries.

Step 4: Link Bank Accounts

Plaid is a very popular and effective API in the FinTech app development industry, helping link your bank account to the app. This API carries out many tasks that otherwise would be very difficult for you to complete. Plaid speeds up the development process, reduces risks, and aggregates your users' financial data.

Yodlee is another financial data consolidating API that helps to access bank accounts efficiently.

Step 5: Integrate Payment Gateway

To set up a secure and smooth payment gateway, we strongly recommend Stripe. As a global payment processor, it merges several payment service vendors into one solution, so your customers don't need to save their credit card details and abide by the PCI certification. You can also integrate Stripe with Plaid.

Step 6: Establish Chat Support

Chatbot provides an amazing API that can effectively automate your customer support system. As this API is powered by Machine Learning and Natural Language Processing, it can facilitate a wide array of complex operations, such as the pre-approval process for applicants. It uses open-source libraries like scikit-learn.

Step 7: Add Plug-Ins

If you are considering adding financial management to the property owners' dashboard, go for the Intuit API. It consists of a set of tools that reflects the economic health of an enterprise. This API owns Mint and QuickBooks.

If you want to implement a data visualization feature in your FinTech app development, D3.js is the best framework for you. This JavaScript library uses CSS, SVG, and HTML to manipulate data and create visualizations. So, if your app needs to build a visual representation of your user's financial data or just enterprise budgeting and resource planning, D3.js is the perfect API for you.

Step 8: Consider Legal Requirements

While building FinTech apps, remember that you will handle users' sensitive data at your own expense. And hackers would love to get their hands on this data. Hence, let's discuss a few more actions you must implement in your FinTech app:

1. Carefully go through legal obligations related to accessing the financial data of your users with these APIs

2. Implement an insurance policy to cover you if a data breach occurs

3. Develop data management and privacy regulations

4. Create a business continuity and disaster recovery plan in action

Providing the best FinTech services does not sum up your responsibility. You need to go all the way and take extra steps to gain users' trust and reliability, as they will invest their life savings in your initiatives.

Tech Stack We Use for FinTech App Development

Once you have determined the functionalities and design of your FinTech app, it's time to choose the right tech stack for the front-end and back-end development as well as other categories. So, let's explore the different tech our app developers use for robust FinTech application development.

The table above is just a general recommendation; the tech stack used for FinTech application development depends on your project objectives, requirements, expertise, budget, and timeframe.
