  • Is fintech software development outsourcing a good idea?

    • Outsourcing fintech software development can be a great idea for businesses looking to reduce costs, increase efficiency, and access a wider pool of talent. 

      Outsourcing can provide access to highly skilled professionals with expertise in fintech development, who can work on your project at a lower cost than hiring in-house. It can also help you focus on your core business activities and avoid the costs and risks associated with hiring and training new employees. 

      However, it's important to choose the right outsourcing partner to ensure the quality and timely delivery of your project.

      2. Choose the right development team with experience in fintech app development.
      3. Create a user-friendly design that incorporates security measures and compliance regulations.
      4. Develop the app's backend functionality and integrate it with external APIs and data sources.
      5. Test the app thoroughly to ensure it meets user requirements and is secure and compliant.
      6. Launch the app and provide ongoing maintenance and support.

      It's important to work with a reputable fintech development team that can provide end-to-end services and ensure the success of your project.
  • What are the differences between hiring an employee on an employment contract and B2B?

    • B2B and employment contracts primarily differ regarding the body of law to which the parties to both contracts are subject. For an employment contract, it is the Polish Labor Code, and for B2B contracts it is the Civil Code.

      One of the more significant differences is the tax and social security payment liability. The employer covers these costs for an employee under an employment contract. In case of a B2B contract, the costs are borne by the contractor. 

      In addition, an employee on an employment contract is provided with paid vacation (20 or 26 days depending on tenure), paid sick leave, and additional days off for occasional special situations (funerals, births, etc.). An individual on a B2B contract may be provided with paid vacation under the terms of a gentleman's agreement with the employer.

      Both contracts also differ in their notice periods: for an employment contract, the notice period ranges from 2 weeks to 3 months, while for a B2B contract, it is flexible, but usually 1 month. 
  • How long does it take you to deliver a specialist/a team of specialists?

    • It depends upon the role, its complexity, and technical requirements. Usually, it takes us between 5 and 15 working days to fill a vacancy.
  • How do Link Group’s contractors report their working hours?

    • It works both ways: Contractors monitor and report their hours directly in the client's ATS system, where at the end of each month managers approve them or conduct the hourly reports in their Spreadsheets (also approved by the managers).
