Custom ASP.NET development services involve professionals using Microsoft’s ASP.NET Core framework to make custom apps. A group of skilled individuals can design, build, and implement custom web applications or backend systems from scratch that meet the specific needs of a client’s business .NET developers are hired (often from outside). Custom ASP.NET development makes software for businesses that is tailored to their needs and ways of working. A custom development service encompasses the whole development lifecycle, from gathering requirements and designing the user interface and user experience to coding, quality assurance, deployment, and maintenance. The end result is an ASP.NET web app that was made from scratch and works with other Microsoft tools like Azure cloud and SQL Server databases.

When Is It a Good Idea to Hire Custom ASP.NET Development Services?

When Time and Speed-to-Market Are Very Important

When speed and time-to-market are critical, specialized ASP.NET services deliver faster because they have established development processes, reusable components, and experience with similar projects. If you need to quickly prototype an application or have a tight deadline, hiring an experienced ASP.NET team can expedite development (for example, a startup building an MVP on ASP.NET). With minimal supervision, they can get started right away. If you hire an agency, they can quickly add team members or change schedules to meet your timeline if you need to scale up or speed up the development of your custom solution.

For Projects that Need to Grow Quickly or Have Resources that Can Be Moved around Easily

If your development needs aren’t always the same, such as if you think you’ll need more developers for six months, an ASP.NET service is a great choice.  You can hire them for that time instead of hiring permanent staff. You can change the size of the outsourced team as the project’s scope changes. This flexibility ensures that you are never short-staffed, which could cause delays, or too many staff, which could waste money. Dedicated development teams can help you quickly add or remove staff without the long-term hassle of hiring people yourself.

When a Whole In-House Development Team Is not Available

You need front-end and back-end developers, database experts, QA testers, UI/UX designers, project managers, and other people to build a complicated web app. Many companies lack all of these skills in-house, particularly startups or non-tech companies. You can get a ready-made team of professionals right away with a custom development service. Compared to attempting to assemble and train an entire in-house team from scratch, this can be quicker and more efficient. An ASP.NET agency can supply skilled C# developers, QA engineers, and architects who begin working on your project right away as a cohesive team if your business has a small IT staff.

When You Need Help with a Specific ASP.NET Project or Adding New Technology

Some examples of custom implementations you might need to do are building a Web API for mobile apps, converting old .NET Framework programs to ASP.NET Core, connecting to Azure cloud services, or adding high-security features to a banking or healthcare app. A custom ASP.NET service provider will send you developers who have worked on projects like yours before.  If your company mostly uses Microsoft products like Azure and SQL Server, hiring ASP.NET experts who know the ecosystem can ensure that your current systems work well with the new ones. They can also help you make architectural decisions by using best practices from the industry.

For Complex, Long-Term, or Evolving Projects

A specialized ASP.NET development team is a good choice if your project is a key business application that has grown over time or if the needs are always changing. If a project is going to take a long time, change a lot, or needs technical skills that your staff doesn’t have, consider hiring outside APS.NET developers.  The outside team can stay involved as the project moves forward and share their deep knowledge of the latest ASP.NET Core features, cloud integrations, and more. This is also helpful if you want to speed up development because an outsourcing partner can quickly add more developers as the project’s scope grows.

When Your Internal Team Is Full or You Want to Focus Their Attention Elsewhere

There are times when your IT or development team has too many other important things to do, like keeping systems running, working on other projects, and so on. When you hire an outside team to work on a new ASP.NET project, they can handle the specialized development work while your internal team focuses on strategic or core business tasks. Businesses often use this method to give out tasks that don’t happen very often or only once. One IT executive said that hiring a group of qualified developers to work on short-term development projects keeps your internal team focused and saves you money on hiring more full-time staff for a short-term project.

When Not to Hire Custom ASP.NET Development Services

When the Desire for Customization Is Eclipsed by Financial Constraints

Custom development costs more than using software that is already available because you have to pay engineers to make something new. If you have a very tight budget or aren’t sure how much money you’ll make from a custom solution, hiring a development company could be hard on your finances. Be careful: the cost and scope of custom software can quickly go over your budget if your needs change. Small businesses or startups that are just getting started may want to start with simpler technology that isn’t as customized until they have the money to build something custom. In short, don’t hire a custom development team if you can’t afford the costs, plus a little extra in case things go wrong.

For Projects that Are Very Small or do not Last Long

A full ASP.NET development service might be too much if you only need a script, a very simple web page, or a tool that you will only use for a few weeks or months. An independent developer or even a tech-savvy employee could do these kinds of tasks. If you only need software to add a small feature or fill in a small gap, you might not need to hire an agency; in those cases, a simpler solution is often good enough.

When a Simple, Ready-Made Solution Can Help You

You might need a simple content website, a basic CRM or ERP feature, or something else that a lot of people can get from a product or SaaS tool. It’s usually faster and cheaper to buy or use an existing solution than to make one from scratch.

If you only need something for a short time or once, hiring developers to make a custom system might be too much. A pre-made software product might be a better option.

You should only use custom ASP.NET development when you need a system that current products can’t provide or when you want a system that is unique to you to get an edge over your competitors. There are platforms, like Shopify, that can meet 90% of your e-commerce needs right away.

You should only choose custom ASP.NET development if the other 10% (or other factors like integration, self-hosting, etc.) make it worth it. You can buy and change a lot of ready-made tools. Some even let you brand them to make them look different.

Instead of paying for custom development, it might be better to choose an open-source project or commercial product that already solves the problem and isn’t a major selling point for your business.

Benefits of Hiring a Bespoke ASP.NET Development Company

Better Results and Following Best Practices

External consultants and developers can bring new ideas and proven methods to your program because they have worked on a lot of different projects. This can lower risks, speed up development, and make sure that the finished program meets high standards for performance and quality. Their experience helps you stay away from common mistakes. They will also make sure that the application follows the best practices in the field, such as using the right architectural layers, following secure coding standards, and doing thorough testing.

Access to Modern Skills and a Full, Skilled Team

When you hire an ASP.NET development company instead of just one software engineer, you usually get a whole team of the right people, like project managers, front-end and back-end developers, QA testers, and more. This “instant team” has worked on similar projects before and knows a lot about ASP.NET (C#, .NET Core, SQL Server, Azure, etc.). One big benefit is that you don’t have to hire someone for each job.

Less Management Work and More Focus on the Core Business

If you hire a specialized staff to handle the technical work, your management may be able to focus more on important tasks like planning products and making basic business decisions. The development service will take care of the developers’ daily project management. They will fix technical problems, make sure things keep moving forward, and often send a project manager to keep an eye on the work. That makes it easier for you to be a manager. When you hire an outside team to do the work, your internal staff can focus on other projects because the outsourcing partner takes care of the details.

Utilize the Newest Technology and Security Procedures

Companies that develop ASP.NET stay up to date on changes in the market and Microsoft’s technology stack. You can get access to the latest features by hiring them, such as advanced libraries (like SignalR for real-time features or Blazor for rich web UI), cloud services integration (like Azure functions and DevOps pipelines), and more.

They also bring a lot of security knowledge to the table, which is built into ASP.NET’s features, such as protecting against common online threats like SQL injection and XSS and providing the right authentication and authorization. This means you won’t have to start over with your research and work on the latest security needs and advancements for your project.

Post-Launch Maintenance

One of the best things about working with a development service is that they will always be there to help. After the initial creation, the companies usually offer support or maintenance contracts on demand.

Developers can easily make changes, fix bugs, and add new features to your program, like moving it to the latest version of the codebase .NET in the future. If something goes wrong in production, you can call on professionals to fix it. This gives you peace of mind that the solution will always work and be up to date.

You can skip the usual hiring delays (job ads, notice periods) and cut the hiring cycle from two to three months to just a few weeks because Belitsoft already has pre-screened, certified engineers ready to work.

2. Turing

Many clients have used Turing to hire C#/.NET programmers, but the platform’s main selling point is that it has a wide range of skills rather than being an expert in just one stack. That said, you can definitely find .NET developers on Turing.

Turing’s vetting will make sure that the .NET engineers you hire know the language and framework well, but you might not get the same level of expertise and best practices as you would with a dedicated team .Belitsoft is a team that focuses on .NET and gets things done.

On Clutch, Turing usually charges between $50 and $99 an hour. This is frequently less expensive in the US than employing developers inside. However, it’s important to keep in mind that Belitsoft’s Eastern Europe model frequently falls inside that range. Furthermore, there are other factors that contribute to value than the price tag. Belitsoft’s price includes a managed service (like PM, QA, etc.), but Turing’s price only covers coding work.

Turing is a global talent marketplace that assists businesses in locating talent. Turing’s method of working with people all over the world may cause problems with time zones and cultural differences. Also, it’s not a good idea to not know your developer’s exact country or time zone ahead of time.

Staff augmentation is the most important part of Turing’s idea. It lets you hire vetted developers who you can directly supervise. In the absence of Turing, you will have to rely on internal methods for tasks like testing, code review, and architecture direction. Having a supplier who takes full responsibility for quality is not the same thing. It can be hard to fully integrate Turing-provided developers into an existing team because there isn’t a standard way to manage things, which can lead to mismatched processes or communication gaps.

If you need a whole team, using Turing means putting together people who have never met before, maybe from different countries, and then figuring out how to manage and coordinate their work.

You and Turing have a “partnership” with different developers every month. If you end a contract or a developer decides to look for other work, continuity may be affected.

Knowledge transfer will take place at some point, which could delay the project. Its main focus is now on staffing solutions instead of being a software development partner for decades.

Turing is about the people, not the procedure. If you have an internal strategy and feel comfortable overseeing developers directly, Turing can work; but, you will need to cover any management holes.

Turing also seems to make scaling easy because it has a large network of remote engineers and freelancers. In theory, you can add more developers to the platform as needed. But in real life, it can be hard to use Turing to put together a bigger, more organized team. Each extra Turing developer has their own contract. It would take time for each new hire to get used to the team, and it would take work to make them collaborate together as a team because they probably haven’t done so before.

Furthermore, there is no assurance that the precise abilities you require will be accessible immediately. Sometimes, Turing couldn’t find the specialist that a client needed quickly enough. Turing’s promise focuses on the abilities of the engineer rather than the team’s subject-matter expertise.

As the client, you must ensure that the developer you choose is aware of and complies with industry regulations if your project is in a highly specialized or regulated field. While Turing’s “success story” is often one step removed, Belitsoft’s success stories are about projects they have completed: It recounts the success of a client’s project using Turing talent.

3. Globant (Latin America) Assessment of .NET Development

One of the largest software development and IT consulting firms to emerge from Latin America is Globant, which has expanded rapidly. Globant employs tens of thousands of people, including consultants, data scientists, UX/UI designers, and developers. Its main office is in Argentina, and it has major development centers in Brazil, Mexico, Colombia, Uruguay, and other Latin American countries.

.NET is one of its many areas of expertise. Front-end development is frequently associated with Globant. They concentrate on creating visually appealing apps. Globant can also build business back-ends using technologies like, even though that’s not their main area of expertise.NET.

It’s more expensive to hire .NET engineers in the US than it is in Eastern Europe, especially if they work for a software company like Globant that is listed on the NYSE. The majority of their initiatives are for large, expensive international corporations. Belitsoft, on the other hand, offers middle-market businesses with small budgets senior .NET engineers who want the same or better quality but don’t want to pay twice for top talent from big companies. Belitsoft works on medium-sized and large projects for American businesses, but not only those.

4. Atos (Western Europe)

Like Capgemini or Accenture, Atos is a multinational provider of IT services and consulting with its headquarters located in France. Tens of thousands of people work for the company in dozens of different nations. They build huge, complicated enterprise .NET systems for banks, businesses, and governments.

They are pricey, nevertheless, just like other Western consulting organizations. Senior Atos consultants in Europe or North America charge exorbitant fees. Mid-sized businesses can’t afford to use Atos for regular software development. Atos wants big contracts, not small ones.

You can use .NET apps to run your IT for years or to make entire digital platforms. Working with Atos is like dealing with a lot of red tape. Several committees and managers must approve any changes. That is sluggish, and it could be challenging to swiftly alter course using Atos. Atos works with Fortune 500 companies that spend a lot of money and can handle slow processes.

5. NTT Data (Japan)

NTT Data, a part of the NTT Group, is a big Japanese IT company that employs more than 190,000 people. They are among the largest IT firms in the world and collaborate with large corporations.

.NET programming is typically included in larger consulting contracts with NTT Data. People often don’t pay attention to projects with only a few developers. The company is not focused on small projects where a few developers work on a specific Microsoft technology stack.

NTT pays less attention to mid-sized businesses that need a specialized service than to large businesses .NET team or want to make a one-of-a-kind app. At NTT, there is a great deal of red tape and regulations. Even if they hire teams from other countries, their prices are set up for businesses with big budgets.

6. Deloitte (North America)

Deloitte is among the top four consulting firms worldwide. They use Microsoft’s .NET technology to make custom software. For example, they use ASP.NET for complex web apps and .NET for fast backends. The majority of their .NET work is completed as part of larger consulting projects that include linking ERP systems, creating analytics platforms, and developing other business solutions.

Deloitte works on expensive, regulated projects in many fields, such as banking, healthcare, government, and energy. These initiatives include integrations with large banks, medical record systems, and government tax systems. These projects need the security and dependability of .NET.

Deloitte is in charge of whole projects for big companies. They could work for the government to make a citizen portal based on .NET. With a new .NET system, a business can employ them to enhance its operations. Additionally, Deloitte offers projects that make use of .NET, AI, and IoT.

When Deloitte works on a .NET project, they deploy business experts to ensure the product is compatible with your business processes and software developers to write the code. They often send smaller expert teams to work with offshore workers in India and other countries, but they can quickly hire more people from around the world if they need to.

Deloitte costs a lot of money. Developers are less expensive but still very expensive. Strategy consultants are the most expensive. It could be very expensive to work with Deloitte on a .NET project. If all you need someone to do is make software, you’re paying too much.

Deloitte often leaves after finishing the job. You should either hire someone else to do maintenance or do it yourself. If you would like, Deloitte can offer managed services long-term support, but the cost would be higher. Deloitte and other big companies aren’t very flexible. Less famous firms give you the same technical results for better .NET development, but with more freedom and personal attention.

7. CGI (North America)

CGI is an IT outsourcing and consulting firm with headquarters in Canada that serves companies worldwide. Its main focus is on creating enterprise applications .NET, which includes important business apps, ERP extensions, and government systems.

CGI developers are good at making .NET software that can grow and is safe. They often use the framework’s business benefits, such as security and Microsoft product integration. They also focus on cloud deployments and .NET Core for modern solutions.

Working with the public sector, government, banking, healthcare, and utilities is CGI’s primary area of competence. They have assisted thousands of government clients with system updates since 1976. For instance, CGI may create a large government resource planning system or a financial management platform for a federal agency using .NET. They know a lot about procurement, compliance, and long project cycles because they have worked in the public sector for a long time.

They frequently employ offshore developers and local consultants to work on their projects; they have offices in India and other locations. To manage the entire delivery process, they assemble groups of analysts ,.NET developers, testers, and frequently subject-matter specialists for the customer. Because of their size, CGI can keep promises for many years and, if necessary, put a lot of people on a project.

Development services from CGI are typically expensive, particularly when they deal directly with governments or Fortune 500 businesses. They frequently operate on a time-and-material or fixed-price basis and have stringent contracts.

CGI is renowned for effectively completing national government portals, defense and intelligence systems, and hard integrations. Updating old systems, many of which were built on mainframes or other obsolete technology, to work with modern technology. There is a lot of talk about .NET web-based solutions that make things work better. CGI is very reliable, but it can be slow and inflexible because of how it works in businesses.

8. HCLTech (HCL Technologies)

It is a well-known IT services company that is good at creating future-ready .NET solutions. These solutions cover the entire .NET stack, including cloud integration (Azure), .NET Core microservices, enterprise application development, and .NET solutions with AI/ML.

HCL is good at big, important projects like banking systems and telecom platforms because .NET is reliable and secure. HCL has a large number of .NET developers, including architects and subject matter experts, because it has more than 220,000 employees around the world. For a project, they are able to assemble sizable, dedicated teams.

HCL uses a lot of agile and DevOps methods. They also focus on research and development and new ideas, so they use best practices like automated testing and CI/CD in their work.

HCL’s prices are similar to those of other Indian companies because it can get work done more cheaply in other countries. This helps the client save money on big projects. HCL may have higher minimum engagement requirements than smaller suppliers, and it usually goes after contracts with big budgets.

HCL is very helpful for big projects, but it can be harder to use for smaller ones. Customers should be ready for calls at odd hours, like early in the morning or late at night, because a lot of growth happens in India, just like with any other supplier based there. Most of the time, communication is formal.

HCL doesn’t have smaller teams that work on specific projects, so every developer is carefully screened and added to the project. This prevents anything from becoming “lost in the shuffle,” which is a common occurrence with large teams at HCL.

9. Cognizant (India)

Cognizant is a big IT service provider that makes new .NET apps and updates old .NET software. They use Microsoft .NET products like ASP.NET and the most recent version of .NET. Cognizant can also add AI and data analytics to your .NET apps.

Tens of thousands of engineers are employed by the organization worldwide. It is less expensive to hire coders from India than from the US or Europe. If additional personnel are required for your .NET development project, Cognizant can promptly add them.

When there are so many engineers who work from far away, it is hard to keep the quality consistent. People with varying skill levels may work on the same project. Over time, you may collaborate with different developers because staff members come and go.

Most of your engineering staff will be more than twelve hours ahead of you or behind you, which is the largest issue. Most of the work is done in India, so you only have a few hours that are the same as US or European time. Only in the early morning or late at night can real-time collaboration take place.

English is spoken by Indian offshore teams. You might, however, run into people who are too formal, don’t speak English well, or don’t fit in with your culture.

10. Tech Mahindra (India)

Tech Mahindra makes .NET apps using the latest Microsoft tools. Their developers are good at DevOps, setting up cloud .NET solutions, and moving old systems to new ones .NET. In all areas of the Microsoft stack, they are very good at engineering. They have worked in both finance and telecommunications.

For instance, they can create a .NET platform or digital banking apps to assist telecom firms in monitoring their offerings. Tens of thousands of people work for the large corporation Tech Mahindra. They may assist large teams with a wide range of tasks, including .NET engineering, business analysis, UX design, and testing. Southeast Asia and India are home to the majority of their delivery facilities.

For an Indian outsourcing company, their rates are reasonable. But like other big Indian companies, they might have contracts that aren’t flexible or minimum staff sizes. Working with Tech Mahindra’s offshore employees has a few issues. Because of the different time zones in North America and Europe, you may have to join calls at odd times. The distance could make it hard to talk to each other. Planning some .NET projects might take longer.

What Is the Price of Hiring ASP.NET Development Company?

Dedicated Team / Monthly Rates

If you hire a dedicated ASP.NET development team using the staff augmentation model, you will usually pay each developer a monthly fee or a single monthly fee for the whole team. The cost per developer each month depends on where they live and how much experience they have.

For example, an ASP.NET developer from an Eastern European outsourcing company may charge $7,200 a month. At least $10,000 a month would be much more expensive in the US.

When all costs are taken into account, businesses can save about 40-50% on development costs by hiring specialized offshore developers instead of local ones. A dedicated team model may have a minimum engagement term, such as 3 or 6 months.

Fixed-Price Project Costs

Under a fixed-price contract, you pay a set amount for the work that needs to be done. Here, the price is totally project-specific and will be calculated by adding a margin for risk and the number of developer hours needed.

For instance, the fixed price could be about $10,000 (plus some contingency) if the project is expected to take 225 hours to complete and the blended hourly rate is $45 per hour.

One crucial point is that vendors frequently include a buffer in fixed bids to account for uncertainties, so the quote may exceed the time estimate alone. Change requests will increase costs if requirements change during the project.

ASP.NET applications for large businesses (with many modules and a lot of complexity) could cost hundreds of thousands of dollars, while small, well-defined web projects (like a simple company website or web portal) could cost a few thousand dollars.

Always obtain a comprehensive quote, and if you’re using a fixed price, consider breaking it up into phases.

Variations by Region in Rates

The pay and rates for developers differ a lot from one area to the next. ASP.NET developers cost more in the US and Western Europe than they do in Eastern Europe, where the cost of living is lower and the skills are usually the same.

For example, a full-time ASP.NET developer in the US usually makes between $80,000 and $125,000 a year, which is about $70 an hour when you break it down by the hour. On the other hand, senior .NET engineers in Eastern European countries like Poland make about $60,000 a year.

This shows that businesses can often save 30-50% by hiring developers from Eastern Europe or other offshore areas instead of the U.S. This is a big reason why companies choose to outsource.
