Got questions?

We got answers

When does your business need custom software?

This approach is necessary when you have obviously outgrown your legacy software and realize that it has become much harder to maintain. As you start looking at the readily available options, there turn out to be no out-of-the-box solutions that fit your specific case. Actually, custom software may be required even when a seemingly suitable off-the-shelf solution is available, but you just need more scalability, flexibility, and efficiency.

What are the key stages of the custom software development process?

The key stages of the software development process include research (to determine the most suitable technology stack for the project), design (this one includes creating a project plan and a functional specification coming up with a time and budget estimate), development, testing, launch, and maintenance.

Depending on a specific project, some of the stages can take more time, or require some additional actions. For example, AI/ML projects require much more research, as compared with mobile application development.

What factors are crucial to the success of a custom software development project?

First and foremost, you need to partner up with a company that has proven software development experience and a portfolio of completed projects.

During the development process, you need to have clear goals and objectives set for each of the development stages. You must also establish transparent communication and put efficient project management in place. Besides, it is important to have a procedure for control delegation between you and your software development provider.
