How to choose a software development company in London
If you are reading this article, you are probably looking for a software development company in London.
Since London is one of the leading IT hubs in Europe, the options are endless.
It’s worth knowing how to choose the most suitable software development partner and what criteria to consider.
As a custom software development company in London, we recommend considering the following criteria when choosing the most suitable vendor.
1. The portfolio of works
Established software companies or web development companies in the UK should have a publicly available portfolio with former design and development works.
If your preferred vendor has previously worked in your industry on similar projects, they will most likely understand and meet your requirements.
Therefore, we recommend checking the following information in the portfolio:
- Former client names
- Testimonials
- Project types
- Project duration
- The industry
- The team setup
- The testimonials
- The impact of the work
Last but not least on our list is the impact of work. In other words, what was achieved as a result of the collaboration.
Your chosen software company should help you design and develop a software product that meets your users’ needs and business goals.
2. The online reputation
The online reputation refers to all possible information, positive or negative, you can find about your preferred company on the Internet.
We recommend conducting quick research to find unbiased information and honest opinions about your software company in London.
How to check the online reputation?
Type your preferred company’s name in the search bar and google it. What information do you see there? Does it have a dedicated LinkedIn page with brief information about the company’s location and services?
Does it have independent reviews on Clutch or Trustpilot?
Is it featured in media?
Does it have any awards or recognitions?
Reviewing the online reputation will help you understand whether your software company is active, how it operates internally, and to what extent the former customers are satisfied.
3. The collaboration process
Whether you will work remotely or on-site, it is essential to know how the collaboration process with your preferred London software company will look.
We refer to the frequency and means of communication. It’s also important to agree on how the feedback will be communicated and implemented in work.
As a client, you want to ensure the job is done flawlessly. Therefore, we recommend keeping track of the progress.
At Limeup, most of our client projects happen remotely. Therefore, we’ve developed an effective remote collaboration process to work with clients from different time zones.
Our software designers and developers organize weekly calls via Zoom to communicate updates and show the work progress. We keep in touch with our clients between the calls via different collaboration tools, such as Slack, emails, Microsoft teams, etc.
We want to make sure the result meets our client’s expectations. Therefore, we always ask for feedback and implement it on a weekly basis.
