Receiving payments as an unregistered business

Hey trevor, I am starting a small shopify business in Singapore

. It says I need to provide additional info abt my business to receive payouts. Even tho, I am a beginner i still provide but it says i need to provide a UEN. DO i need a Uen number because UEN is very expensive and I sure know that a small shopify store doesnt need it, plus how do other people receive payments without having UEN around the world. Thanks in advance
