      Web Design Review from Brendan Murphy

      Llt group designed and developed a website for a recruitment firm. The team was responsible for web design, UI/UX design, frontend development, and backend development. they were communicative and open to feedback throughout the project, fixing errors and making design changes as needed. Still, the project was delayed a couple of weeks, as Llt' team was a bit slow at implementing those changes. The dedication to their work was outstanding.

      This place was great for many years but is apparently out of business although I can’t be sure. I am an existing customer and just got a new bill even though I just paid my bill. I have called and emailed many times - no response. Not sure what’s going on. Stay away.

      101 digital seems to have just shut down services, with no notice to it's clients. They don't answer the phone, and emails auto answer with a message to contact Anita at Sunny Direct, who also doesn't return phone messages or emails. They've left us in a very difficult position just as we head into our busiest time of the year. If they come back in any form, I'd suggest buyer beware!

Frequently Asked Questions

What is a .NET development company?

A .NET development company is a business that specializes in creating software applications, dynamic websites, games, and other services based on .NET, Microsoft’s free, cross-platform, and open-source development platform. Today, over 38 million live websites use ASP.NET. 

.NET development companies typically have expertise in the new, unified .NET Standard and the following components: 

  • .NET Framework: Collection of tools, programming languages, and libraries for creating software and applications. 
  • .NET Core: Open-source developer platform for building applications 
  • Xamarin: Platform for building applications for iOS, Android, and Windows 

What is a full-stack .NET developer?

A full-stack .NET developer builds both the frontend/interface and the backend/content management systems (CMS) of .NET projects. Their wide range of skills in both technology stacks presents some key advantages over a front-end- or back-end-only developer: 

  • You’ll need fewer team members to complete a project, significantly reducing overall costs. 
  • Familiar with both sides of the project, a full-stack developer can troubleshoot, fix issues, and fill gaps quicker.  
  • As there’s no back and forth between front- and back-end developers, there’s less miscommunication, mistakes, and delays. 

Are .NET and ASP.NET the same?

No, .NET and ASP.NET are two different things – the former is a software framework, and the latter is an application. 

  • .NET is a framework used to build various software applications and services, including applications like ASP.NET. 
  • ASP.NET is a software application used to build websites, web services, and web applications. 

You can think of ASP.NET as an application developed on the .NET framework for the specific purpose of creating software for the web.

What services does a .NET development company provide?

A .NET development company typically provides a range of software development services, including: 

  • Desktop application development 
  • Web application development 
  • Mobile application development 
  • Game development 
  • Cloud solution development 
  • Technical support and maintenance 

Over the course of a project, a .NET developer may: 

  • Plan the software development process and break it down into tasks 
  • Write source code using C#, F#, or Visual Basic 
  • Test the software using manual and/or automated techniques 
  • Discuss project progress with the stakeholders and present developed functionalities 
  • Launch the software and make sure everything operates as planned 
  • Maintain and update the software after deployment  

How much do .NET development companies charge for their services?

.NET development companies charge $5,000 to $20,000 for simple projects and up to $250,000 for large-scope projects, like a customer relationship management (CRM) system for a medium-sized business. Extremely large and complex projects that take years to develop may even require a budget of over $1,000,000. 

Here are some typical price ranges for different kinds of .NET projects: 

  • Small website: $10,000 to $50,000+ 
  • Cross-platform mobile app: $50,000 to $150,000+ 
  • Large enterprise application with integrations: $200,000 to $1,000,000+ 

The top 50 .NET development companies on DesignRush charge an average of $57/hour. Roughly 13% of the .NET development companies on DesignRush accept projects with a minimum budget of less than $1,000, while 5% have a $50,000+ minimum budget. 

Why should you hire .NET developer companies?

You should hire a .NET developer because outsourcing offers the following benefits: 

  • You save costs: According to an in-house vs. outsourcing report, outsourcing software development costs $45/hour on average, compared to $75/hour for in-house development. 
  • They have more experience: Experienced developers with a lot of .NET projects under their belt typically deliver higher quality work. 
  • Faster process: With an external team, you don't need to expend resources to recruit and train an internal .NET developer. 

Here is an example of a successful project by a .NET company called ScienceSoft: a client needed an efficient BI solution for internal management, external financial analytics, and automated customer invoicing. The .NET company developed an analytics web portal, client web portal, reporting tools, and other supporting features from scratch. 

After the .NET development company implemented the BI solution, it improved the speed of reporting by 90%. It also fully automated processes like customer invoicing, enabling significant time savings. 

How do you choose the best .NET development company for your business?

You can choose the right .NET development company by following these steps: 

  1. Define project scope: Decide on a minimum viable product (MVP), product features, and functionality. 
  2. Set project requirements: Make a checklist of goals and the means to achieve them (e.g., deliverables list, timeline, communication guidelines, preferred technologies, etc.). 
  3. Set a budget: Look for the best talent in a range you can afford. If you have a small budget, try expanding your search to countries with more affordable prices. 
  4. Inquire about experience: Ask the .NET development company for a portfolio and similar project examples from your industry.  
  5. Check credentials: Ask for .NET certifications like Microsoft Certified Solutions Associate (MCSA), Microsoft Certified Solutions Developer (MCSD), or Microsoft Training Associate (MTA). 
  6. Choose the development approach: Depending on the project, the company should offer an Agile, Waterfall, or hybrid development methodology. 
  7. Send a request for proposal (RFP): An RFP contains the project introduction and scope, technical requirements, evaluation criteria, budget, and submission guidelines. Select up to five .NET development companies and send them an RFP. 
  8. Review RFPs: Go through each proposal, compare results, and interview your shortlisted companies. 
  9. Make a decision: Pick a .NET company based on your top criteria and examine the contract before signing.
