Hello Marckkkk. I used to face the same problem as you and did not know how to register and generally what to do to open a business in Singapore. Then a friend advised me to this https://osome.com/sg/incorporation/
site and I found a lot of useful information there and they helped me set up a company in this country in the shortest possible time. I also want to notify you that you do not have to come to Singapore, everything can be done remotely, especially during a pandemic. Follow this link to learn more and contact a professional who can answer all your questions and help you quickly with all the necessary documents.
