S4N has the flexibility to offer a broad array of solutions, ranging from small one-time projects to on-going, large development or maintenance efforts. We can work with you either on a Project Outsourcing or Dedicated Team basis.


A profound knowledge of the domain, technology expertise, the best-in-class processes and a proven track record of successful delivery enable us to work using a project-based model, thus sharing all the development-related risks with our clients. As part of this project-based model, S4N provides a full cycle of software development services that can be tailored to meet your specific business need. We offer the Project Based model on both the Fixed Cost and Time and Material cost structures.


S4N provides a full cycle of software development services that can be tailored to meet your specific business needs. Time and Material is the best choice for those R&D projects where the overall amount of the required development effort cannot be predicted in advance, or where the business requirements for the software being developed are frequently changed during the development process.


Fixed Cost pricing model is suitable for projects with a known scope, or those projects where changes in the business environment do not affect the project’s functionality. In case you do not have any clearly defined requirements and technical specification, S4N can develop it for you, accurately estimating the development effort and delivery schedule and setting realistic budget expectations.


Dedicated Team is a group of developers with a set of specific skills who meet the project and business requirements and are based at our offshore production center.

  • Operational management, network and IT administration
  • Infrastructure, including office space, workstations, secretarial services, PC repairs
  • Staff management, coaching and supervision
  • HR and recruitment activities, including advertising, pre-screening, interviewing
  • Startup support and consulting about the best existing practies for managing remote development teams

A Dedicated Team works as a natural extension of your own IT department following your processes and best practices. It understands the nature and specifics of your business and duly responds to the frequently changing requirements. A Dedicated Team can be available to you for a fixed monthly fee.

The Dedicated Team model allows you to set up a dedicated offshore operation with minimum risks. We establish software development teams in the Ukraine to enable our clients to work directly with the developers, thus reaching the highest level of productivity possible.

We leverage our expertise of the local market to create a pool of candidates whom you will have the possibility of screening personally. Once the manpower is in place, we will simply set up the workplaces and equipment.
Everything, from the recruitment process to the operational management, will be handled jointly with you.
