Global Assignments

Single Point of Contact

The same person throughout the entire assignment.

Fixed, Transparent Packages

Individual cost framework, continuously reviewed.

One point of contact who holds everything together — from the initial feasibility query to repatriation.

Most assignments don’t fail due to one major problem, but due to gaps between stakeholders: The lawyer waits for HR, HR for tax advisors, the family for an answer.

Complete coordination means: I keep track of all stakeholders, drive deadlines, translate between technical languages, and am available to both the company and the seconded individual. You manage one relationship — not a dozen.

What's included.

Coordination & Management

The common thread: Who does what, by when — and who holds it all together.

Authorities & Legal

Deadlines and permits — that’s where costly mistakes happen.

Individual & Family

Assignments rarely fail because of the job — but because of the arrival process.

Finances & Provisions

Taxes, social security, payroll — cleanly coordinated.

Not every assignment needs everything — but every one needs someone who knows what is necessary in their specific case. We will discuss what is needed in your individual case during the initial consultation.

Erfahrungen meiner Kunden

In den vielen Jahren, in denen ich mit Natalie zusammengearbeitet habe – bei internationalen Entsendungen für mein Team wie auch persönlich – hat sie mir gegenüber immer wieder Integrität, Vertrauenswürdigkeit und eine positive Serviceeinstellung bewiesen, wenn es darum ging, die zahlreichen Hürden zu meistern, vor denen ihre internen Kunden stehen.
Natalie bringt ein hohes Mass an Professionalität in ihre Rolle ein und ist stets bestrebt, den bestmöglichen Service zu bieten. Sie holt sich fortlaufend Feedback von allen beteiligten Seiten, um die Zusammenarbeit aufeinander abzustimmen und die Aufgabe zum Abschluss zu bringen. Sie liefert den Kunden schnelle und tragfähige Lösungen und ist herausragend darin, Menschen zusammenzubringen, um die gewünschten Ziele zu erreichen.
Natalie hat das Projekt in allen Phasen unterstützt.
Statt fünf Dienstleister zu koordinieren, hatte ich eine Ansprechperson — und zum ersten Mal das Gefühl, dass jemand die ganze Entsendung überblickt.
Unsere Mitarbeiterin ist mit Familie in die USA — Schule, Visum, Steuern. Natalie hat alles aufgefangen, bevor wir überhaupt wussten, dass es ein Thema wird.
Was uns überzeugt hat: die persönliche Verlässlichkeit. Eine Person, die zurückruft, die mitdenkt und die auch an den Menschen denkt, nicht nur an den Prozess.
Wir hatten vorher zwei Entsendungen selbst gestemmt — und dabei viel Lehrgeld bezahlt. Mit Natalie lief die dritte spürbar ruhiger.

What steps are involved in complete assignment coordination? From the initial feasibility check to repatriation: contract drafting, immigration and visa, tax and social security clarifications, moving and relocation, local onboarding, ongoing support, and repatriation. You always know the status of your assignment and who is working on what — and your team doesn't have to manage the interfaces themselves. I take care of that.
What legal and administrative requirements must be met? Depending on the country combination: work and residence permits, reporting obligations, tax liability in the home and host country, social security coverage including A1 or Certificate of Coverage, payroll compliance, and reporting. I clarify early on which of these apply in your case and monitor deadlines. Costly mistakes almost never arise from malicious intent — but from an overlooked reporting obligation.
Which countries do you support assignments to? The focus is on Europe, the USA, and Asia; also beyond through an established partner network. I have particular depth in the DACH region — immigration, social security, and payroll for Switzerland and Germany. What is crucial, however, is not the flag on the map, but clean, timely coordination on site.
How long does assignment preparation take? Realistically 4 to 16 weeks, depending on the destination country. The critical path is almost always immigration — permit procedures cannot be accelerated, only meticulously prepared. That's why I clarify feasibility and deadlines right at the beginning. Better an honest timeline than a target date that won't hold.
What costs are incurred for an assignment? The major blocks are immigration, relocation and housing, tax consulting, allowances, school fees, and travel — plus the internal effort that is often forgotten. I will put together the cost framework for you before you commit, and I continuously monitor it against the budget. During the initial consultation, the scope of work will be discussed, and a corresponding package will be tailored for you.
How is the employee's family supported? School and housing search, support with settling in locally, assistance for the accompanying partner, intercultural preparation. This is not an accessory: assignments rarely fail because of the job. They fail because the family doesn't settle in the destination country.
