Through interviews and process analysis, we build a deep understanding of what app your business needs and lay out a detailed description in a functional specification.

Our talented UX and UI designers can create from scratch or refresh your app to make it look like brand-new – super convenient and stylish.

Creating a custom web app involves a lot of coding and testing. That’s exactly what we love and do expertly for 24 years already.

Does your web app need to exchange data with other systems (also legacy and custom-built)? Manual data transfer is out of the question – trust us to plan and set up integrations between systems to automate data flows.

Whatever reasons for migration you have, we’ll create a custom web app that solves your current problems, be it poor app scalability or costly maintenance of a legacy system.

Having ScienceSoft for web app support is really convenient – we can cover all tasks to improve your app, from monitoring and troubleshooting to evolving it with new features.

We will eagerly join your web development team to bring specialized skills and deeper expertise or help speed up the project progress.

Is Custom Web Development Costly?

This is one of the most frequent concerns about custom development. We asked Vadim Belsky, our Head of Web Development Department, to clarify if this concern is grounded:

Head of Web Development Department, ScienceSoft

I cannot share a precise cost estimate that will suit any project. Nobody can, as app types are so numerous and projects are so different. Very roughly, I can say that the cost of a customer-facing web portal starts at $70,000, and the cost of enterprise web apps ranges anywhere from $50,000 to $200,000 depending on the scope and complexity of supported functions. Whether it is costly or not – each company decides for itself. But I can say with certainty that we advocate custom development only if our meticulous business analysis proves a custom web app to be the most feasible solution for a company, even cost-effective in the long run.
