We initially approached XB Software to create a single-page web application for the purpose of supporting the dermatology and dermoscopic research community with a large, searchable collection of images. Over the years, the number and complexity of features have grown, and we have been thrilled to keep working with XB Software's development team.

Web DevelopmentSoftware DevelopmentWeb Design

We began with a broad UX design, then moved into development. Our ASP.NET code base was well over 1M lines. The application has 4 major dashboards with many parts per dashboard. Elements on the UI are data-driven: some grids have 100 columns from which the user can chose. We chose to implement the UI in typescript. As we moved into coding, I was pleased that XB structured the code well, making good use of inheritance to create a container from which each part would inherit. Each part having controls groups above and below the grid. It took XB a bit to get used to how data-driven our UI would be - but now we have classes that handles it all. As excellent as their code is overall, they are a little too likely to use an AWAIT (which I get), but we have been able to work together and be very productive. To this day, I am comfortable assigning tasks to resources at XB when we need a little extra on our team!

We had a great experience working with XBSoftware on our Custom Compliance CRM system. Their team was professional, communicative, and clearly understood our needs from the start. The final product has streamlined many of our internal processes and improved overall efficiency. Throughout the project, they were responsive to feedback and delivered updates on time. It’s clear they take pride in their work and aim to build long-term partnerships rather than one-off projects. We’re very pleased with the outcome and would confidently recommend XBSoftware to anyone looking for a reliable and capable development partner.

My experience working with XB on the Enquiry Medical project has been consistently excellent. From the outset, they demonstrated a strong grasp of the healthcare domain’s complexity and were quick to engage with the clinical logic underpinning the system. Communication was clear, timely, and proactive—issues were never left hanging, and I always had confidence that tasks were progressing as expected. The development work itself was of high quality. XB approached each feature with care and precision, often anticipating potential edge cases and making thoughtful suggestions that improved both performance and usability. Their team showed an impressive ability to balance flexibility with structure—adapting to our iterative development process while ensuring that code quality and architecture were never compromised.

I have been working with XB for the last couple years on a passion project. I started by downloading the Webix library and they answered all my basic questions and probably annoying questions before I had engaged their development services. Once I contracted with XB to develop the my web app, XB has been a fantastic partner. Working within my budget and always communicating with me and keeping the project on track. As problems have arose the team always takes responsibility and and gets things fixed. I look forward to continually working with XB in the future. I would recommend companies small and large consider XB for their next web development project.

I addressed my ideas and requirements to XB Software’s team and they came back with the working solution. I aimed to create MVP of my future app to test the idea on real users. I needed both front-end and back-end development. I also wanted XB Software designers to create an eye-catching web design for the app. They created design and concepts and documented all the requirements. After that, the PM/BA planned how to implement everything and shared the plan with me. Love my team of two developers, a designer, PM/BA, and the account manager. I had a lot of doubts because it was my first experience working with an outsourcing company. But they made everything possible to help me. They conducted a business analysis to improve the concept and provided consultation and kick-off meeting before starting the design and development. They helped me to make my mind what the technology stack would be the best to achieve my goals in the shortest time. For the back-end they used Node.js and for the front-end, they used Webix framework, their own product. They also implemented QA testing. I'm also satisfied with the engagement model. We have a weekly call with the PM. He comes with the results they have. I also have access to Jira so I can monitor all the tasks/tickets. I would recommend working with them. They have their own products that remain leaders marketing positions, so I’m sure they know how to build apps that will pay off investments. You can trust your project to XB Software, just talk to your PM and of course, listen to him, and you will find that is the best way of custom software development outsourcing you may get.

When we started evaluating front-end libraries for a new project for one of our clients (who among leaders in their field in Europe) - we took a good look at Webix (maker of UX/UI components, a sister company of XB Software) and thought it might be a good fit. We contacted them about schooling and after a positive experience we asked them if they provided software development services. That's how we came in contact with XB Software. With their help we assembled a remote team of UI/UX experts to supplement our internal team. I found the whole team to be very engaged, thorough, hardworking and talented (hi to Vera, Alexey and Ujin - you guys did a great job :))! I was particularly impressed by their creativity and attention to detail. As a software developer and owner of a software development company, I consider myself well- placed to judge the quality of the work the team produced over the space of 20+ months. It's top-notch. I can wholeheartedly recommend XB Software, and definitely plan to work with them in future projects if the opportunity arises.

XB Software developed a small part of your ticketing system that included HTML/CSS/Javascript that was done very professionally and all communications were outstanding. They asked the right questions and delivered a very well documented code that we can continue to work on. I would very much recommend them for outsourcing, this was my first time doing outsourcing and I must say I was very surprised how well it went!

Visit Profile

What is your company’s business model–in house team or third party vendors/ outsourcing?

XB Software is a full-cycle development company of custom enterprise solutions as well as own IT products. XB Software has an in-house team and implements IT projects using its own resources.

How is your business model beneficial from a value addition perspective to the clients compared to other companies' models?

XB Software delivers IT solutions to companies seeking to outsource web apps development. We help our clients to speed up time to market by delivering quality solutions on demand. What makes XB Software unique is that it is more than just an outsourcing company. It develops own successful web products such as Webix UI JavaScript library that allows building cross-platform HTML5 and CSS3 compatible web and mobile apps faster. Therefore we can share this valuable experience with its clients. For XB Software its clients are its partners with whom the company always tries to build long-term relationships. As a client-centric company, we provide transparency of all process for our customer and highlight all possible problems and ways to prevent them.

What industries do you generally cater to? Are your customers repetitive?

Our clients request to develop apps and projects that belong to different industries. The key industries we are focused on: Business Services, Consumer Services, Healthcare, Financial Services, Logistics and Transportation, Education, Information Technology. XB Software offers the development of complex solutions that represent a bunch of integrated application modules as a custom ERP service provider. We build different EAS solutions: booking, scheduling, tracking systems and fully integrated and customizable ERP modules. Moreover, we have a great experience in сross-platform cloud solutions development with excellent data visualization capabilities. Most of our clients are repetitive because we keep the high-quality of source code, have the constant dedicated development and QA team, and provide only high-end solutions. Our client retention rate is 70%.

Mention the objectives or the parameters critical in determining the time frame of developing a web app.

Mostly it depends on the number of features in an app and its complexity. Creating a plan that includes accurate project time estimation is a task that requires deep experience and significant efforts. A complex software project can consist of hundreds of interrelated tasks with overlapping dependencies. For estimating a budget and time required for the configuration of the project, our team, first of all, study the project requirements carefully. Then our business analytics deeply analyse company structure and business processes, study KPIs, reveal the aspects that need improvement, and finally formulate a development plan. And at the final stage, we calculate how many resources our client is ready to invest in the project.

How much effort in terms of time goes into developing the front end and back end of a web app?

Mainly we specialize in front-end development as well as challenges regarding front-end UI features. We probably spend 70% of our time on the front-end development and about 30% on the back-end. We use a flexible and extremely fast JavaScript UI framework with HTML5 widgets for developing cross-platform HTML5 and CSS3 compatible web and mobile apps.

What are the key parameters to be considered before selecting the right platform for a web application?

The overall goal of our work is to benefit our customers’ business by increasing the level of their clients' loyalty. That's why, before developing a project, our business analysts carefully study all business areas and the features of the future project, discuss the functionality and other issues with the customer. We are always based on the received information and the positive experience in developing the similar projects. On this basis, we make a decision on what platforms and technologies will be implemented.

Which platform and technologies do you prefer to use in development of your web apps?

Our technology expertise includes React.js, Marionette.js, Webix, Node.js, PHP/Laravel, .NET, etc. We use cross-platform frameworks and technologies, such as PhoneGap, WebRTC and Webix JavaScript UI library that allows creating consumer-centric and business applications for different industries.

Do you offer UX/UI design templates or customised UX/UI design, and do you have a responsive UX/UI design?

We create outstanding individual solutions and customized responsive UX/UI design for any business purposes. Our aim is to design the shortest and most effective patterns of user's interaction with an app. Moreover, our team created own competitive Webix JavaScript UI library that allows fast creation of the great UX/UI of the future app. Our skilled and creative UX and UI developers and designers have 5+ years of proven experience in web app development.

Do you provide App modernization services and maintenance services?

We provide business application modernization service that helps different companies avoid redundant operating costs through reducing capital inputs, business processes acceleration, and decreasing risks. We help resolve critical questions such as whether to migrate, re-platform or remediate legacy applications, what is more, beneficial for the business of our clients. For moving legacy applications towards modern, user-friendly apps we use Node JS, React JS, .NET Core, PHP, Webix, and other technologies. Moreover, we provide maintenance services and after sales support. Our team always stays in touch with our clients after the app has been released or commercialized. We always closely cooperate with our customers especially when the app has been launched and released to production. We also offer individual conditions for after-launch maintenance of the app for every client and a free consultation both for new and existing customers.

What are the key factors that you consider before deciding the cost of a web application?

We work using both Agile and non-Agile methodologies and can combine them to get the most out of each methodology to the benefit of your project. The development cost basically depends on the requirements of the client (I mean the future features of the app or system) and of course the number of hours and other resources expended by our development team for creating the future project.

What kind of payment structure do you follow to bill your clients? Is it Pay per Feature, Fixed Cost, Pay per Milestone (could be in phases, months, versions etc.)

XB Software works under the two contractual models: Time & Materials on the one hand, and Fixed price on the other. Our dedicated team compares the project needs of a client with the models described below and selects the most appropriate contract type. We work using both Agile and non-Agile methodologies and can combine them to get the most out of each methodology to the benefit of your project. We work in full compliance with ISO 27001 and ISO 9001 standards. We are proud that XB Software is among the 29% of respondents of the Hi-Tech Park of Belarus that have passed ISO 9001 certification and among the 12% that have passed ISO 27001 certification.

Do you take in projects which meet your basic budget requirement? If yes, what is the minimum requirement? If no, on what minimum budget you have worked for?

We have no restrictive limits on budget requirements. The minimum budgets we seek to work for is from $5K.
