Essential Integrations for a Money Transfer Application

Integrations for a Money Transfer Application - ScienceSoft

To enable fast and accurate funds movement between the involved parties, a money transfer app needs to seamlessly transmit data on the requested money transfer transactions to the processing system of a chosen bank. The latter validates the sender’s personal and financial information and passes transactions to the relevant regional or global processing networks (e.g., the ACH network, SWIFT, VISA / MasterCard / American Express card network, etc.) to finalize funds settlement between the money sender’s and money receiver’s banks.

In money transfer app development projects, ScienceSoft relies on market-available open banking APIs to connect a money transfer app to the bank’s processing system, facilitate access to the user information necessary for KYC verification, and allow real-time acquisition of up-to-date exchange rates for multi-currency transfers.

NB! Cryptocurrency transfer processing requires integration with dedicated blockchain networks of the crypto coins that a money transfer app supports. ScienceSoft employs ready-to-use cryptocurrency APIs (e.g., Coinbase API, CoinGate API) to streamline the connection of a money transfer app to the required blockchain networks.

Depending on the business model, a money transfer app may also need to be integrated with an accounting system of the app provider, for example, to instantly record data on the received transaction fees. Additionally, the solution may be connected to a data analytics system to share relevant data required to analyze the app users’ behavior, which is essential, e.g., for app monetization via in-app advertising.

A Roadmap for Money Transfer App Development

A typical process of developing a money transfer application with ScienceSoft looks as follows:

Business analysis and requirements engineering

Duration: 1–3 weeks

From the very beginning and through the whole project, ScienceSoft maintains close and consistent collaboration with a client’s team to get an in-depth understanding of their money transfer needs or the money transfer app vision and avoid the risk of costly redevelopment. At this stage, our consultants:

  • Analyze a client’s current business situation and business needs/the product vision.
  • Elicit and document requirements for the money transfer app, including:
    • The required type of a money transfer app (web or mobile).
    • Requirements for the app’s functional capabilities, for example, support for particular transfer types (P2P transfers, P2B transfers), transfer methods (bank transfers, card-to-card transfers, etc.), currencies, transfer models (e.g., recurring transfers), and more.
    • The types and formats of data the app should be able to process.
    • UX requirements.
    • Non-functional requirements for the app (performance, scalability, availability, latency, etc.), including security and compliance requirements (with AML and KYC, PCI DSS, ISO 20022, etc.).


Project planning

Duration: 1–2 weeks

By accurately planning money transfer app development, ScienceSoft’s project managers lay the basis for transparent, KPI-driven cooperation with minimized risks. This stage includes:

  • Defining objectives and KPIs.
  • Determining project deliverables, duration, schedule, and budget.
  • Deciding on the roles in the project team and designing collaboration workflows.
  • Identifying possible project risks, creating risk mitigation strategy and plan.
  • Estimating TCO and ROI of the money transfer application.


Money transfer application design

Duration: 3–6 weeks
  • Architecture design. We describe how the solution’s functional modules should perform at the code level and decide on the best-fitting approach to the integration between the app’s components.
  • A detailed list of features. Apart from the core features, the list covers recommended security features for the app’s infrastructure and compliance procedures to meet the required standards and regulations.
  • UX/UI design for the required user roles (individuals, corporates, admins, etc.). We perform UX research, deliver prototypes, conduct usability testing, create the visually appealing style of the app, and provide UI mockups.
  • A plan of integrations. We advise on optimal integration solutions (open banking APIs, crypto APIs, etc.) and design custom integrations with existing back-office systems, if needed.


Tech stack selection

Duration: 2–3 weeks on average
  • Defining techs and tools required for the money transfer app development.
  • Comparing different techs and tools in the context of documented business requirements.
  • Selecting the optimal techs and tools.

To optimize project duration and costs, ScienceSoft suggests employing ready-made components (building blocks for the app logic, prebuilt UI components, OOTB deployment scripts, etc.), if applicable.



Money transfer application development

Duration: 4–7+ months, depending on the solution’s complexity

At ScienceSoft, this stage starts with configuring CI/CD pipelines and setting up container orchestration tools to facilitate further app development, integration, deployment, and release. Upon establishing the automation environment, our team proceeds with creating the app’s back end, implementing a PCI DSS-compliant storage for app users’ sensitive data, and developing role-based user interfaces.

We perform quality assurance of each app component and check how the components work together in parallel with coding to eliminate possible vulnerabilities and logic errors and fix any defects before deployment.



Integration with other systems

Duration: 2–5 weeks (depending on the integration complexity)

At this stage, ScienceSoft’s team integrates the money transfer app with required software. We conduct integration testing to guarantee proper functioning the integrated solution.



Application deployment and release

Duration: 1–3 weeks

We configure the app’s infrastructure, backup and recovery procedures, implement relevant security tools (authorization controls for APIs, DDoS protection algorithms, firewalls, IDSs / IPSs, etc.), and set the ready-to-use app live.

NB! ScienceSoft can also assist in creating a website for app promotion or uploading the money transfer app to the required web or mobile app stores to streamline app release.



Support and evolution (optional)

Duration: continuous

ScienceSoft offers a range of services to ensure the smooth operation of the money transfer app in the long run. Particularly, our team can:

  • Monitor the app performance and handle operational issues.
  • Scale the app to serve a growing number of users.
  • Perform security and compliance audits.
  • Develop and release new functionality according to a company’s or end users’ evolving needs.
