UNDERSTAND HOW ERGONOS SUPPORTS ME

An international assignment is more than a signed contract

Accepting an external assignment is often much more than an agreement between a consultant and a company.

Even before the project begins, several questions may arise: which status should be used? Who invoices whom? How are expenses managed? Which social security or tax framework applies? What happens if the assignment is extended, relocated or modified? How can the relationship with the client be secured without making the process heavier?

These matters are important, but they should not prevent you from focusing on your real value: your expertise.

Ergonos steps in precisely at this point: between your skills, the client’s needs, the country of assignment and the contractual framework. Our role is to make this relationship simpler, clearer and more secure.

Without support, an assignment can quickly become complex

With Ergonos, the framework becomes clearer

Why work with Ergonos?

A clear framework for delivering your expertise

Every assignment is different. Your status, country of residence, country of assignment, project duration and client expectations can all influence how the collaboration should be structured.

Ergonos helps you work within a framework tailored to your situation. The objective is simple: avoid grey areas, clarify each party’s responsibilities and enable the assignment to start on solid foundations.

Less administration, more time for your assignment

Invoicing, contractual documents, expense reports, client communication and administrative follow-up are all necessary, but they can quickly become time-consuming.

Ergonos acts as a coordination point to streamline the relationship between you and the client. You keep your energy focused on what truly matters: the success of the project.

Practical support in international contexts

When an assignment involves several countries, local rules, travel or a complex project environment, administrative and contractual matters become more sensitive.

Ergonos helps you find a pragmatic, consistent solution that fits the assignment context. You are not left alone to make these decisions.

A stable point of contact over time

A consulting career is often built assignment after assignment. Having a partner who understands your background, constraints, preferences and way of working can make a real difference.

At Ergonos, we prioritise long-term relationships built on trust, transparency and clarity.

TALK TO ERGONOS

Several frameworks are possible depending on your situation

There is no single way to collaborate with a client. The right framework depends on your profile, the assignment, the country involved and the project constraints.

Ergonos helps you identify the most suitable solution.

Freelance Contract Management

You remain an independent consultant, while Ergonos coordinates the contractual and administrative management of the relationship with the client.

This solution may be suitable if you want to maintain your independence while simplifying communication, invoicing and administrative follow-up related to your assignment.

International Temping

In some cases, Ergonos may employ you for the duration of the assignment.

This solution may be relevant when the project context, country of assignment or client expectations require a more structured temporary framework.

Employer of Record

When an assignment requires a local contract in a given country, Ergonos can act as the Employer of Record.

This solution makes it possible to set up a local employment framework without the client having to create an entity in the country concerned.

Your expertise, our framework

Ergonos steps in where an assignment can become complex: between your know-how, the client’s operational needs, the constraints of the country of assignment and administrative requirements.

Our objective is not to standardise your career path, but to find the framework that enables your assignment to run under the best possible conditions.

What we clarify with you

During an initial discussion, we can help you clarify the key aspects of your situation:

  • your current status;
  • your country of residence;
  • the country in which the assignment will be carried out;
  • the expected duration of the assignment;
  • the type of project and the expected role;
  • the collaboration arrangements with the client;
  • invoicing, employment or umbrella company considerations;
  • expenses, travel or practical conditions;
  • specific constraints linked to the country or sector.

This analysis helps to better understand the possible framework and anticipate the points that need to be secured before the assignment starts.
