Sending workers to another country

An installation, a site or a service abroad: documentation travels with the person, and ahead of them.

Updated on 13/08/2026

Sending three people abroad to install something for two weeks looks like a logistics matter, and it is mostly a documentary one. Some obligations must be met **before** they leave, and an inspection at destination may ask on site for papers that sit in your office.

What is usually required

DocumentWhenWhere it must be
Prior posting declarationBefore departureFiled at destination
Applicable social security legislation documentBefore departureWith the person
Contract and applicable termsBefore departureAccessible, often translated
Role training and fitnessValid on those daysWith the person
And a reachable representativeDuring the postingDesignated in writing

Important

The last row surprises most: many countries require designating someone reachable during the posting, and "call head office" does not satisfy it. It is a formal requirement met with a name and a contact, and almost nobody prepares it.

Why it gets complicated in practice

  1. 1

    Requirements vary by country

    And by sector. What worked in one does not work in the next.

  2. 2

    They change without notice

    What you did two years ago may be out of date.

  3. 3

    Documentation is requested on site

    On a site, to an inspector, with a phone as the only tool.

  4. 4

    And it must be provable afterwards

    Sometimes months later, once the posting has ended.

Watch out

The expensive mistake is preparing the posting with documentation in a folder on an office computer. If the inspector asks at destination and the person cannot show anything from their phone, the result is the same as not having it.

How to organise it

Worth knowing

The same applies in reverse: if you host workers from a foreign company at your premises, you will need to be able to evidence that you checked their documentation.

Does it apply to a two-day trip?

It depends on the country and the work; many do not distinguish by duration.

What if they are self-employed rather than staff?

The documents change, not the obligation to evidence it.

Who should know the requirements?

A specific person in your company; delegating it entirely to the destination client does not exempt you.

A real case

The situation

A company sends three installers abroad with the paperwork left at the office.

What you do

  1. Opens a per-posting file accessible from a phone
  2. Designates the reachable representative in writing

What you get

The inspection at destination is resolved on site and there is a record for afterwards.

The situation

Who travels is decided the week before.

What you do

  1. Checks per person what documentation is current

What you get

The trip is not discovered blocked at the airport.

The situation

The documentation travels with the person on paper.

What you do

  1. Also keeps it accessible from a phone

What you get

A lost paper stops halting the work.

The situation

Somebody changes at the last minute.

What you do

  1. Keeps more people current than actually travel

What you get

The change is resolved by picking somebody who can go.

The situation

The destination client asks for different papers.

What you do

  1. Asks for the list before preparing anything

What you get

You prepare what they ask for there, not what applies here.

The situation

Nobody knows what expires before the trip.

What you do

  1. Warns about expiries in advance

What you get

Renewals happen before travelling.
