We've set up a UK subsidiary so I can relate, but the process in Sweden was approximately 10x simpler: more automated, less bureaucracy, less ongoing admin work when the company is up and running.

As with all countries there are definitely things you need to learn. We relied on our lawyers to draft employment agreements because we were already using them as part of our seed fundraise. There are companies like Pocketlaw (https://pocketlaw.com) that provide solid, standard agreements that you could use.
