  • Scalability

    • As your SaaS company grows, you need to ensure that your infrastructure can support the increasing demand for your services. This requires a scalable architecture that can handle spikes in traffic and usage.
    • Cloud-based infrastructure

      Move to a cloud-based infrastructure, which can provide scalability on demand. This can include using cloud platforms such as AWS or Azure, containerization, and Kubernetes.
    • Microservices architecture

      Implement a microservices architecture that can be scaled independently, allowing you to scale only the services that are in high demand.
    • Load testing

      Conduct load testing to identify the bottlenecks and capacity limits of the SaaS application. Based on the results, optimize the infrastructure and application code to ensure scalability.

  • 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).
