11. AI/ML integration: Ensure to integrate AI/ML technology in your app to personalize your products or services.  

Step-by-Step Guide for Fintech App Development

Now that you have learned the important features of fintech applications, it is time to find the answer to the question “How to build a fintech app step-by-step?” This process requires a deep understanding of the target market and audience, along with substantial technical expertise in this field. Once you collaborate with a leading fintech app development company, you can streamline the entire process easily and focus on your organizational goals completely. 

Step 1: Understand Target Audience & Market Gaps

The first step you need to take for successful fintech app development is to learn deeply about your market. For example, who is your target audience, who is your competition, and if there are any gaps in the market your app can fill. If users find your product to be more helpful than your competitor’s, they will certainly switch to your app. Not just that! The usability, popularity, and revenue of your application will attract investors’ attention, too, in the long run.      

Start with a roadmap, like a few fintech features we have specified above, and then add at least one unique feature that will help your app stand out in the market. Aside from that, you should also work on the localization of software to attract users from various markets. Keep in mind, a localized app can deliver a smooth user experience across multiple languages and regions, making your app more accessible to the audience worldwide. 

Step 2: Create a Project Brief & Plan Features

Once you have done your market research, you will know which sort of fintech application is required to solve the pain point of your target audience. Accordingly, you can begin planning the budget and features of your fintech application. There are several types of fintech applications you can create. For instance, a bill payment platform can help users pay for all the utilities they leverage from different service providers by simply scanning a barcode.

Post planning, when you start working on a project brief, make sure to define the scope of your Minimum Viable Product or MVP. In case you are not familiar with a project brief, we must let you know that it is a small document whose objective is to describe the goals, requirements, and solutions so that you and your development team stay aligned. When creating such briefs, do remember to keep the following steps in mind:   

1. Organize a product discovery workshop with your development team to gain clarity on which features are necessary to have and what tasks people can perform using your application. 
2. Discuss technical requirements with your team and see if there are any challenges, like the need to integrate your app with legacy systems. 
3. Set milestones for every important feature before getting involved in detailed planning.

Step 3: Design a Clean User Interface

Simple and intuitive UI/UX is necessary for every app, but it matters even more for fintech applications. In the banking and financial industry, apps are designed to guide users through multiple financial activities. The more complicated the workflow is, the cleaner and more user-friendly the interface has to be. Onboarding is one such area that most financial applications struggle with. Want to know how?   

Fintech applications have to collect plenty of information about their users to comply with regulations such as KYC (Know Your Customer) and others. However, asking for a huge amount of information at signup can piss off users to a great extent. To deal with this issue, you can take advantage of progressive signup to gather information over time or make use of gamification to satisfy users when they are filling in their information. 

For the unversed, progressive signup is a UX design and marketing strategy that helps collect user information gradually over multiple interactions instead of all at once in a single, lengthy form. 

Step 4: Develop & Test Your MVP for Security & Compliance

It is the best time to commence MVP development, once you have the design, user stories, and a complete description of the first release. Here, a user story means a short description of a software feature explained from the end user’s perspective. 

Keeping in mind security and compliance risks, there are multiple things you need to integrate into fintech app development: 

1. Always encrypt data and rely on API penetration testing to discover any vulnerabilities in your APIs. 
2. Make only the last three digits of the credit or debit cards visible when developing or testing on staging environments. 
3. Ask users to re-enter their password if they want to do any high-risk activity. 
4. Perform a comprehensive vendor assessment check first if you wish to incorporate third-party APIs. 
5. Implement a Zero Trust security model outside and inside your company. This means users, devices, and apps must be verified prior to giving them access to precious data.      

Step 5: Launch & Iterate Depending on Feedback

Since an MVP allows you to reach your audience fast, you can gather valuable feedback from them and enhance your product. Carry out A/B testing and monitor user comments in a spreadsheet or a specialized usability testing tool to get an idea of what is difficult to understand for them. Additionally, if you want to further understand user behavior, applying Real User Monitoring (RUM) can offer precious data on how your audience communicates with your application.

Be ready to ask questions and make relevant changes once you figure out something isn’t working. The best thing about agile development is that you can keep repeating this process until you reach perfection without disturbing your current workflows.
