I will check it out, but to be honest, I am extremely skeptical. I have been using companies providing similar services for over a decade. Not only they have consistently all been very expensive (35%-45% cut)†, but they all required MASSIVE amounts of paperwork, both from the contracting company and from the "employee". Employee enrolment took at least a month, and this was when the employee was already a resident, and when we already had other employees in the same country. Otherwise it took
much longer because specific contracts in the local language had to be written and approved.
Employee resignation took months, and relocation also took months.
This all sounds too good to be true.
This is with US parent companies and EU employees.
† The least I've seen was 20%, and it was a horror show so bad that it was worth it to switch to a 40% competitor.
