I use Deel to hire people internationally. It's mostly an EOR company. They promised a lot though, I once thought about moving my entire HR workflow to Deel (even for local employees), but quickly decided against it.
Not cheap, but worth it for sure considering how much time they save you.
Deel is the opposite: they provide US companies with gray area (or you could even say illegal in some countries) trickstery to reduce cost of employing people.
