What is outsourcing service?

“Outsourcing occurs when a business pays an outside supplier to provide goods and services, rather than doing the work in-house.”

Outsourcing was considered a business strategy in the late 1980s, and then on, it became a crucial part of business economics throughout the 1990s, according to IBM. While some turn their heads away from outsourcing, business experts opine that it is a great incentive for all businesses and companies to outsource their projects because it offers global talent to work on your product at quite affordable prices, maybe, due to currency differences.


What is an IT outsourcing service?

Since outsourcing found its way to the core of all business strategies, the IT industry was not lagging. In fact, the word ‘outsourcing’ became synonymous with all software development projects such as web development, and mobile app development as most companies from first-world countries started outsourcing their projects to other countries where the currency difference would save them a large amount of money. India, Kenya, and the Philippines became outsourcing hubs and fetched most of the projects from the US, the UK, Australia, Canada, and New Zealand.

IT outsourcing service refers to hiring offshore IT firms or agencies and handing over the entire project to build a customized IT solution for their business. With the help of outsourced IT services, businesspersons could offload their worries and headaches of developing a software solution because they do not need to spend much time managing the teams of software developers and designers. Instead, they would easily focus on other important stuff.

Outsourcing services for software, web and mobile app development projects would include almost everything that you can think of. From merely jotting down your business thoughts on paper to basic consultancy and designing and developing your software application to deploying and marketing -everything is possible when you hire a mobile and software development outsourcing service provider. Most IT outsourcing service providers may appoint a CTO, project manager, team lead and even CIO to lead the project and have personal attention.


What are the different types of outsourcing?

When you hire an IT agency for Outsourcing app, web, and software development services, you may need to know the types of outsourcing depending on which your business strategies may alter. Broadly, you have four types of outsourcing IT services –

Managed IT services: In this model, experienced IT service providers shall manage your in-house developers so that you don’t need to bother about handling the entire IT staff. This model has not been in practice lately. 

Infrastructure management: This model applies to a business tie-up with an IT service provider company that shall manage the entire infrastructure at your premises. Involving both physical and virtual, everything related to hardware, software, and networks is handled by an IT infrastructure outsourcing company. 

IT security: IT security service providers can help you manage all your software tools and products functioning internally and externally. The primary focus is to save them all from malware and cyberattacks of all kinds. 

Offshore outsourcing: probably the most popular model, offshore outsourcing simply means that you contact the best IT company from an outsourcing hub (such as India) and give them all responsibility to design, develop, and maintain your products. This takes off your responsibilities from managing the product development teams; furthermore, with a special contract and NDA, your product is kept confidential and maintained (through regular updates) for any bug or malfunction in the future.


Why use IT outsourcing services?

In-house IT teams in countries such as the US shall cost you a pretty penny. When you opt for an outsourcing company and consulting service, you offload most of your efforts as you will just pay for their services but you don’t have the headaches of managing all teams sitting elsewhere. Best outsourcing companies offer you end-to-end IT services which include building a roadmap, wireframing, design & development, deployment, and maintenance of applications and products.

Here are three primary benefits of outsourced IT services you get when you hire top outsourcing companies for your product development-

Zero management

The biggest hassle most entrepreneurs face is managing software development teams at their premises. This is one of the biggest reasons why companies from America, Europe, Australia, Canada, and New Zealand opt for the best outsourcing companies sitting elsewhere such as India.

Top IT outsourcing companies shall offer you professional designers, developers, and QA testers along with a project manager who will supervise the entire work in the SDLC (software development life cycle). In other words, you will have to manage nothing. IT outsourcing services include regular updates through the online portal so that you can check your project’s whereabouts as and when you want.

Optimum quality

Another cogent reason why IT outsourcing services have been in demand for decades is that businesses from first-world countries get optimum quality at the best prices. This is due to the currency differences and cheap development costs because the salaries paid to software engineers in the US are way higher as compared to those of professionals with similar skills in India. That said, if you fix the deal with any top IT outsourcing companies in the USA, it shall cost you an arm and a leg; on the other hand, the best outsourcing IT companies in India for the same project will save funds that you can invest elsewhere.

Besides, IT company outsourcing offers you the best talent to have from all over the world. You can either search for the best IT outsourcing company in a particular region or country or can ask your tech partner to hire veterans from other fields that your software product requires. For instance, if you are outsourcing IT services for a healthcare mobile application, you may ask the mobile app development company in India to have a physician as a domain expert guiding the mobile development team of designers, developers, and QA testers. Just like affordable software engineers, a physician would also not cost you much for their services.

Deployment and beyond

As a result of IT outsourcing services, you get the final product in your hand that is up to the mark and aligned with your business objectives and the company’s vision and mission. It all happened at affordable costs without compromising the quality of the software. In addition, an IT outsourcing firm can also offer you pocket-friendly maintenance plans so that you are assured that your product is up and running most time.


How to choose IT outsourcing companies?

Now, this is a tough nut to crack. On the internet, there are many top IT outsourcing companies, but to choose the best one asks you to apply some tests. In other words, you may check on these parameters to judge the best IT outsourcing companies for their efficiency in providing quality IT services.

Digital presence:

You may start filtering the IT outsourcing company by checking its own digital presence. What we mean by that is to see their websites and other social media platforms. It is important that if they portray themselves as top outsourcing companies, it should reflect through their digital presence. Active involvement on technology websites, blogs, and forums may mean that they are up to the mark.

Rates and reviews: Though there are IT outsourcing companies on the World Wide Web, not all fall into the ‘genuine’ category. Ratings and reviews on the websites and other third-party portals such as us about the IT service providers shall help you gauge their professionalism. The better the ratings on neutral reviewing websites, the better reliability an IT outsourcing firm carries.

Experience and expertise:

Despite the fact that new companies can also provide you with the best IT services, experienced outsourcing service providers will always have an upper hand. You may, through their corporate website, check the year of establishment and their industry experience. Outsourcing companies with 10+ years of experience, according to business experts, are more reliable as they thrive to maintain their reputation by providing astounding services.

Portfolio and case studies:

Though you get a company after filtering through all the criteria mentioned above, checking out their portfolio and case studies will get you a deep insight into how they work and how they have tackled grave issues while developing software. A portfolio helps you understand whether their outsourcing IT services have ever included a project that is similar to yours; furthermore, case studies will put some light on their problem-solving capabilities.

Budget and time:

After stringent litmus tests, when you are about to finalize a top IT outsourcing company, the final step that decides everything is the budget and time. You must remember that quality comes with a price and, therefore, the best outsourcing companies providing IT services may cost you a bit more but the return on investment is worth it. Also, ask for different hiring models that they offer and you may choose the one that suits your budget for the product. 

When everything is mutually agreed upon and finalized, it is time to have several meetings to convey your business idea and the company’s vision and mission. You may ask their business and technology consultants to jump into the discussion and suggest from a technological perspective. Get the best deal and kickstart your project.
