ScienceSoft Answers Frequent Questions

Is custom software worth the investment?

The major reason to opt for custom software is that mass-market and free tools are often unable to meet unique business needs, don’t support specific integrations, offer limited or costly scalability, and may be more expensive in the long run.

At ScienceSoft, we analyze the financial feasibility of custom software development on a case-by-case basis and consider prioritized options with stakeholders.

How much does it cost to develop custom software?

The cost of custom software development depends on your project’s scale and complexity shaped by multiple factors, such as:

  • Software type and a number of platforms supported (web, mobile, desktop).
  • Number and complexity of software features.
  • Custom software design uniqueness and complexity.
  • Number and complexity of integrations with other software systems.
  • Infrastructure requirements (availability, performance, security, latent capacity and scalability).

You can request free project cost calculation from ScienceSoft if you need to assess planned software.

What cooperation model is better for custom development?

It depends on the development resources you have in-house. If none, you will have to assemble a dedicated team and fully outsource your project to a vendor. If you have a team but lack specific competencies, go for a team augmentation model.

Who decides on the development methodology?

It’s not necessary as your software development vendor will advise on an optimal methodology. However, if you want to know the fundamental difference, here is our brief overview:

  • At ScienceSoft, we use Agile (Scrum, Kanban, XP) to enable fast releases and easy changes.
  • In case accurately predictable budgets/timelines or adherence to industry regulations are in demand, we employ Waterfall.
  • We offer the Iterative model when a customer wants both project flexibility and predictability.

Why should I entrust my project to ScienceSoft?

ScienceSoft is a trusted, reliable software development company with a team of proactive, energetic experts that are laser-focused on bringing tangible, measurable business value.

We know how to keep our customers happy: 62% of our revenue is coming from customers we serve for more than 2 years.
