#2 Planning and Requirements Phase

Once the preliminary data is gathered, now you can proceed with writing down specification for your fintech solution and and drafting an approximate development roadmap.

#1. Drafting comprehensive requirements

Agreeing on and writing down requirements and specs is what sets up the pace for the entire project and defines how the other phases will be conducted. Here are a few examples of what the development team will do in this part of the project:

  • Creating technical requirements to application
  • Developing metrics for project success and completion
  • Creating quality assurance and testing plans
  • Planning the deployment strategy
  • Planning for ongoing maintenance
  • Evaluating legal requirements

#2. Creating documentation

Once the requirements are gathered, it’s essential to create detailed documentation that outlines the project’s scope, features, functionality, and technical specifications, or in other words, Software Requirements Specification (SRS). This documentation serves as a blueprint for the development team and ensures that everyone is aligned on the project’s goals and expectations. Key requirements falling within the scope of SRS include:

  • Functional requirements
  • Non-functional requirements
  • Business requirements
  • User requirements

#3. Solution evaluation

In this stage, the proposed solutions are evaluated to ensure they align with the project’s objectives and requirements. This involves assessing the feasibility of the proposed technology stack, development approach, and design concepts. It may also include a cost-benefit analysis to ensure that the proposed solution provides value for the investment.

#4 Development Phase

With a blueprint, you have a clearer vision of how to develop a fintech software. The process of development mostly consists of front- and back-end as well as the integration of third-parties modules through Application Programming Interfaces (APIs). Implementing security measures and ensuring regulation compliance is also done in this stage. 

#1. Backend development

The backend, or server-side, of the app is developed to handle data financial data management, server interactions, and integration with databases and APIs. This phase ensures that the app has a robust foundation for storing and processing user data securely.

#2. Frontend development

The app’s front end is the part of the application visible to users. Front-end engineers create every element with which a user interacts, from architecture to layout to performance to data and content. It is usually done with CSS, HTML, and JavaScript. Hence, this type of development is responsible for an app’s interactivity and functionality.

#3 API integration

Most applications, especially complex ones, require integration with third-party APIs to add functionalities such as payment gateways, social media integration, and data analytics. This allows the app to leverage external services and enhance its capabilities.

#4 Security implementation

Security measures are implemented to protect sensitive data and ensure the app complies with fintech industry standards and regulations. This includes encryption, authentication protocols, and regular security audits.

#5 Non-functional requirements implementation

It’s worth noting separately that the inclusion of data handling and cybersecurity measures should be aligned with the PCI DSS, or GDPR standards as well as local regulations. It depends on what laws are applicable in the region the potential users of the app are from. Compliance is obligatory, and potential fines for being PCI non-compliant range from $500,000 per case.

Approximate time for the development stage: 3 to 6 months.

#5 Testing Phase

The testing phase helps ensure that the app’s functionality, performance, and security meet the highest standards. This stage involves rigorous testing of the app to identify and rectify any issues or bugs. It may additionally involve testing with a small group of users.
