business registration and permit residence

Hello dear community

my name is John and I am from Germany. For several times I visited Taiwan an i really loved it . I felt totally in love and I decide to start a business over there. Unfortunately I dont have any idea how the process to register business and get permit residence.
So I would like to know if its possible to enter Taiwan and to register just quasi right over there?
Or do I have to arrange all before I enter Taiwan (such like in South Africa)
I couldnt find latest and updated informations.

PS: I am an german passpord holder

Thank you in advance for all who could help me
And greetings to formasa taiwan :slight_smile:

John
