Do you come across terms like ‘IT services company’ and ‘digital services company’ without really being able to tell them apart? Are you hesitating over whether to hire qualified staff or delegate your IT project to an IT services company? Qim info is here to answer your questions about IT companies.

We’re an IT services company ourselves, founded in 2004. This article is aimed both at companies wondering whether they should call on the services of an IT services company, and also at future talent considering working for an IT services company. With our versatility, 600 employees and 120 customers from all walks of life, we’re delighted to introduce you to our industry and dispel a few myths about IT companies.

Let us guide you through this vast sector of new technologies.

Defining an IT services company

How does an IT services company differ from a digital services company, and why has the term changed in recent years? Here are a few explanations.

What does "IT services company" mean?

The term “IT services company” denotes a company offering services in the field of IT and new technologies. The aim of an IT services company is to support a customer’s IT project, and it generally incorporates a number of different professions. At Qim info, our personnel cover more than fifteen professions, some more technically oriented, such as Front-End/Back-end/Fullstack Developer, and others more focused on corporate culture, such as Agile Coach.

What's the difference between the terms "IT services company" and "digital services company"?

The answer to that is straightforward: there isn’t one!. Both terms refer to a service company specializing in IT and new technologies. So why do the French acronyms ESN (“digital services company”) and SSII (“IT services company”) coexist, and are they used interchangeably?

Surprisingly, this name change is purely political! In 2013, the Syntec Numérique employers’ association decided to replace the category “SSII” with “ESN” for three reasons:

  1. To mitigate the overly technical nature of IT services companies by emphasizing the notion of service.
  2. To cover the entirety of digital services, which have evolved considerably and whose services are now much more varied than the initial tasks of integration, maintenance and technical assistance.
  3. To improve the reputation of IT companies, which was fairly poor at the time.

Let’s take a look at the role played by an IT services company.

What is the role of an IT services company?

The role of an IT services company is to offer its expertise in terms of IT solutions and services in a Business to Business (B2B) model.. Indeed, the client companies often need to outsource these elements beyond their own IT departments.

IT services companies’ missions can be divided into two main areas:

  1. Advice, training and assistance for users In short, an IT services company’s mission is to communicate and build relationships with its customers. This may not be as well-known as the more technical services we provide, but it is essential. At Qim info, we make it a point of honor to listen to our customers and advise them on the best solutions for meeting their needs. Our people skills are one of our strengths.
  2. More technical services, including facilities management (maintenance, software test management, infrastructure management, business process outsourcing) and systems integration (architecture, development, technical assistance and software sales) are, of course, the best-known services.

Another important point is that IT services companies cater to all customers, for all types of projects Whether you’re part of a small company or a major corporation, whether you work in medicine or luxury retail, you may need to call on the services of an IT services company.

At Qim info, we work for companies in sectors ranging from watchmaking and trading to public administration. We currently have customers from over 10 different sectors.

We treat each customer’s project with the same attention to detail, and ensure that our solutions are tailored to their specific requirements. To find out more, we invite you to read our article about our IT group.

How do IT services companies work?

Generally speaking, an IT services company operates on an assignment basis. These assignments vary depending on the customer’s needs and the contract signed (daily rate or fixed price). The size, internal structure and business model of IT services companies also have an impact on the services they offer customers.

The assignments

An IT services company can offer to take on various types of assignments. That’s what we do at Qim info, with:

  • Delegation This is our core business. We can provide you with one or more consultants who can bring your IT project to fruition. Delegation is more commonly used when the customer’s request requires a reduced number of steps between the initial request and final realization.
  • Our Center of Expertise This is a service that involves a consultant or an entire team, and for which we make a commitment either in terms of resources (with support), or in terms of results (on a project).

Our Center of Expertise has 6 departments:


IT services companies rely on several levers to carry out their missions. Their operating methods are based on:

  • Customer prospecting
  • Needs analysis
  • Solution design and development
  • Project implementation
  • Tool training
  • Maintenance
  • Service billing

And on the inside? An IT services company is divided into two main families of employees.


First, there are the Business Managers. On the customer side, these are the ones who canvass potential business customers, and it’s with them that you negotiate contracts. Internally, their role is also to support the consultants. This is what we do at Qim info: each employee is supported by a Business Manager on a daily basis, not least so as to prepare them as well as possible for each new assignment entrusted to them.

Then there are the consultants who work with you to implement and ensure the functionality of the IT solutions you’ve chosen. At Qim info, our people are our greatest asset, and the human dimension is paramount. With over 600 employees, we have opened a new branch in Geneva, bringing together experts from our Center of Expertise to support you with all your IT projects. What’s more, beyond these visible roles, we don’t forget the essential behind-the-scenes teams, dedicated to administration, finance, accounting, communications and event organization, who keep our company running smoothly and dynamically.

Last but not least, some IT services companies have a team dedicated to recruitment. That’s the choice we’ve made at Qim info: to find the best talents to bring your projects to fruition. Our hiring process is based ontwo principles we hold dear: transparency and trust. The diversity and richness of our consultants’ profiles are a real strength! We bring together a wide range of skills to offer a unique response tailored to each customer’s needs.

Your time is precious and you need the best experts to take care of your IT requirements. IT services companies put a large team of employees at your disposal, each specializing in a particular field.


IT services companies work with IT suppliers and negotiate the best rates for their customers. At Qim info, we partner with Gold Microsoft. We work closely with Nintex, AWS Partner, Fortinet and TD Synnex, to name but a few.

Cost reduction

Contrary to popular belief, working with an IT services company can be less costly than hiring new staff and setting up training programs. High-quality training takes time and money. By delegating your IT project to an IT services company, you win on both counts.


An IT services company listens to your needs and is able to offer you an adapted solution, taking any constraints you may have into account. Flexibility is in fact one of our watchwords here at Qim info. If a standard solution suits you in every respect, we opt for that one; if you need more customization, we’ll meet your requirements.


An IT services company is familiar with the security and quality standards, as well as the regulatory frameworks to be respected, in order to guarantee the reliability of your IT system. It also masters the issues of tool compatibility, to make your IT system as efficient as possible.

That’s why working with an IT services company in Switzerland is such a cost-effective solution. Delegating an IT service allows you to stay focused on your core business, saving time and improving efficiency.

List of IT services companies' areas of expertise

As mentioned above, the areas of expertise covered by IT services companies are vast. This is why some IT services companies tend to specialize in a few areas, while others choose to offer a wide range of services. Qim info has opted for this second route: we favor versatility, in order to meet the needs of any customer, in any sector of activity. Our aim is to take your project from start to finish, without ever asking you to call in another IT services company to carry out a particular stage of your project.

What’s more, the services we offer are aligned with customer demand and the new needs that emerge as technologies evolve. And they’re evolving fast! It’s for that reason, in fact, that we decided to create our own Center of expertise: The aim is to remain at the cutting edge of innovation in all technological fields.

Our Performance & Observability department

Our sixth department’s mission is to optimize your IT system’s performance. We are reinforcing our expertise in load and performance testing, continuous performance engineering, application performance monitoring, rapid performance diagnostics, strategy and governance, and also resilience and reliability.

Right now, we can identify 3 areas of expertise for IT services companies where demand is increasing:

  • Cloud Computing is becoming increasingly widespread: it enables companies to manage large volumes of data and secure them more easily than with an on-premises strategy. However, making the right choices and managing several types of Clouds is not something you can improvise on, and that’s why we offer our services in Cloud Consulting. We also invite you to take a look at our detailed article on the Cloud.
  • Security With the digitalization of businesses, every company, from the smallest to the largest, uses computer data that is essential to its activity. As a result, IT services companies offer not only data security procedures to guard against the risk of theft or loss, but also recovery or continuation plans should the worst happen.
  • Outsourcing and maintenance : IT services companies are often asked to manage an IT system, without being part of the client company’s team. These services can be provided remotely or face-to-face.

When is it a good idea to call in an IT services company?

We have already set out the benefits of working with an IT services company, and now we can list the cases when this is the best option:

  • You don’t need to hire a full-time IT specialist, but require one or more one-off interventions
  • You need expert advice
  • You want to implement an IT strategy
  • Your IT project is a complex one
  • You want to improve a tool or a process
  • You need some training
  • You want to outsource the maintenance, security and management of your tools
  • You’re short of time

In all these cases, the IT services company will be your best ally.

For how long is it worth your while to be supported by an IT services company?

If you’re looking for an IT services company for a long-term project (design of a new tool, maintenance, ongoing development, tool management, etc.), then the collaboration could last several years. If you’re calling on an IT services company for a one-off assignment (setting up a new system or updating an existing one), then the support will last for a few weeks, or even a few months.

How much do IT services cost in Switzerland?

This is a key question. The cost of IT services depends on several factors:

  • The services requested
  • The company’s location
  • The length of the assignment
  • The complexity of the project
  • The qualifications of the employees assigned to the project

The cost is thus highly variable, and depends entirely on a series of factors specific to each company, but also on the IT services company concerned, its business model and the specifics of your request.

What concrete results can you expect to get from an IT services company?

Here’s the part we’ve all been waiting for: the results! Expertise, reliability, flexibility and cost reduction: the benefits of working with an IT services company are manifold. To be more specific, here is a list of results you can expect to get from an IT services company:

  • Improved quality of service for customers: If the tools you implement have a direct impact on them, the involvement of an IT services company will soon make itself felt in your customer feedback.
  • Optimized operational efficiency Your employees can work more efficiently on repetitive or time-consuming tasks, and thus optimize their productivity.
  • Optimal adaptability to new IT tools
  • Advice and technical support

In this way, an IT services company can offer you significant improvements in the fields of security, quality and digital performance.
