A custom web application is software (accessible via a web browser) developed specifically for a particular organization to meet its unique requirements.

A mature and impact-focused web app development consultancy, ScienceSoft can help throughout the entire custom web app development process, from ideation and planning to design, development, testing, and deployment.

Our 20-Year-Long Story Condensed into 6 Key Facts 







ScienceSoft Is Proficient in Full-Cycle Web Development

Through interviews and process analysis, our consultants can build a deep understanding of what app your business needs, lay out a detailed description in a functional specification, and accurately scope the project.

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 25 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.

Our Custom Web Application Projects

Our Clients Are Our Top Priority

We needed help in revamping a web app for pre-school institutions. ScienceSoft’s PHP team has fixed the app’s security issues and has enhanced its features like financial reporting and attendance tracking to make the app more efficient and easy to use. We are fully satisfied with the current results, and we are going to continue our cooperation with ScienceSoft on this project.

We teamed up with ScienceSoft trusting a solid experience that the company had in the domain of web portal development, and never regretted the decision. ScienceSoft’s team proved to be knowledgeable, thoughtful, and highly motivated.

We entrusted ScienceSoft with the development of our web application for AWS cloud users to gather cloud instance monitoring metrics.

ScienceSoft’s team managed to bring to life our web application with full adherence to the requirements and within the optimistic project plan. Thanks to their solid experience in agile development, our web app was deployed in just 4 months.

Custom vs. Off-The-Shelf Web Apps

Custom web apps

Off-the-shelf web apps

Designed and developed specifically for a particular organization.

Pre-built with standard design and features that are the same for all organizations.

Flexible to integrate with the existing systems and workflows of the business.

May not integrate well with existing systems and workflows, which can lead to inefficiencies and additional costs.

More expensive and time-consuming to develop.

Typically, less expensive in the short run, can be quickly implemented and used by businesses.

App support should be established from scratch.

Typically, an established support system is in place, including user forums, documentation, and customer service, making it easier for businesses to resolve any issues or problems that may arise.

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

Based on ScienceSoft’s experience, building a customer-facing web portal of average complexity costs around $70,000–$300,000, while the cost of an average enterprise web app can range anywhere between $50,000–$250,000. 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.

We are ready to go the extra mile and help you optimize your investment by:

  • Prioritizing features and delivering an MVP first.
  • Adhering to the Agile methodology to provide quick fixes based on user feedback and speed up the return on your investment.
  • Reusing code and using ready-made components where possible.
