I am quoting the author of the article.
If you want to have employees in secondary jurisdictions without having to deal with the specifics of operating within them, you can hire folks through a Professional Employer Organization (PEO) like Deel [1]. They'll take them on as full-time employees, pay benefits, handle paperwork - and assign them as full-time contractors to your business. No nexus for you, and full employment for the person working for you. It's not cheap, ofc, but hopefully your employee is generating sufficient value :)
