      Web Development Review from James Leonard Ehrlich, DVM

      I wanted to outsource front end development while maintaining back end services myself. They started with existing React SPAs, cleaned them up, found and removed bugs, improved user interaction, made clear requests for new endpoints which I implemented and they tested and used. The time difference between my office in eastern USA and theirs in Moravia worked well, as we could meet at their afternoon/my morning and I had the rest of the day to deal with back end or questions they might have. Their professionalism and competency were impressive. I will continue working with them, for years, I hope, in maintenance mode or when we need to expand features.

DesignRush sustains a directory of over 40,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

  • Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
  • The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.

Frequently Asked Questions

What are the core specializations of custom software development companies in the United Kingdom?

The core specializations of custom software development companies in the United Kingdom generally center around web/mobile app development and advanced digital technologies. Their expertise extends to AI-powered products, cloud solutions (especially DevOps), feature enrichment, and cybersecurity.  

Overall, they provide end-to-end digital transformation solutions and engineer custom platforms and systems that drive competitive advantage and business growth across industries. 

How much do software development services cost in the UK?

The cost for software development services in the UK ranges from £25,000 to £120,000 for small businesses. In contrast, large enterprises undertaking extensive digital transformation or building sophisticated, bespoke systems should anticipate costs starting at £80,000 and potentially exceeding £500,000. 

For startups or businesses aiming to validate a concept, the initial cost is considerably lower. A minimum viable product (MVP) or a proof-of-concept generally falls within the £5,000 to £30,000 range. The final price is ultimately determined by the project's complexity, the chosen technology stack, the developers’ experience, and the geographical location of the service provider, which impacts their hourly or daily rates. 

How do I choose the right United Kingdom software development firm?

To choose the right United Kingdom software development firm, begin by evaluating its portfolio and case studies to make sure they have experience in your required technology stack and niche. Inquire about its process and team structure, to make sure they follow an iterative methodology and that the core development team will be dedicated and accessible for regular communication.  

Finally, prioritize a company with good reviews that reflect a track record of robust post-launch support and good collaboration throughout the project. 

Do software development companies provide ongoing support?

Yes, software development companies do provide ongoing support, maintenance, and updates after the product launch. This post-launch service is important for fixing bugs, maintaining security, adapting to changing user needs, and making sure the software remains stable and competitive. 

How do custom software development companies in the United Kingdom handle project revisions?

Custom software development companies in the United Kingdom predominantly handle project revisions through the Agile methodology. This involves breaking the project into short, iterative sprints, allowing the client to provide feedback and request necessary revisions at the end of each cycle.  

This flow is intended to minimize risk and keep the final product aligned with the envisioned concept, rather than waiting until the end for a major change.
