How to Choose the Best Custom Software Development Company

The following section consists of a step-by-step process that can help you choose the best software development company.

Step 1. Define and finalize your project-related objectives

As you may know, projects can be implemented differently and apply different methodologies and tech stacks.

Thus, the first step in IT outsourcing is to do your homework; namely:

  1. Note your business size and industry focus
  2. Create a general description of the project idea and its aim
  3. Define an acceptable project timeline
  4. Work out a list of project-related aspects (e.g. features, platforms, tech stack you want to apply, etc.)
  5. Develop a list of questions for the pre-screening process to evaluate IT outsourcing companies
  6. Understand the budget you are ready to allocate
  7. Figure out if further tech maintenance and support are needed

Step 2. Shortlist top software development companies

In the beginning, you may search on the net, use our software development companies list, or turn to platforms like Clutch.co, GoodFirms, or Manifest. These resources can help you shortlist 3-5 IT providers that suit you the best.

To complete this step, you should check out the following information:

  • Industry focus and completed projects in the domain you need
  • Tech specialization and capabilities
  • Online reviews and client testimonials
  • Company’s accounts on platforms (e.g. GitHub, Behance/ Dribbble for design, etc.)

Well, you need to consider lots of factors like the estimated project duration and required budget, documentation, software development tools, languages, frameworks employed, the number of developers assigned to the project, and so on.

  • Factor 5 - SDLC (e.g. methodologies used, quality assurance and bug fixing processes, ongoing support process, scalability, etc.)
  • Factor 6 - Tools used (e.g JIRA for project task management, Harvest for time tracking and billing, GitHub and GitLab for source code management, Confluence, etc.)
  • Factor 7 - Legal side and security aspects (e.g. NDA, Contract terms & conditions, privacy policies, assurance of data security)
  • Factor 8 - Sample deliverables (e.g. code samples, design samples, programmers’ resumes, etc.)
