Starting a Retail Business Here in Singapore

GnM_Merchandising

Hi I have an intention to bring in some merchandise (e.g. clothing, cosmetics, etc.). I wish to that via Pushcart and being a sole distributor here in Singapore and maybe in the region. But after reading lots of things about registring a business, Home Office, Home Based Small scale business... I am already Blur... I hope anyone can enlighten me with my queries:

1. I need to register a business thru ACRA if i want to import those stuff and sell it here in Singapore (pushcart, or any other means)...right?

2. Registering a business is quite straight forward...but the one that confuses me is the Business Adress. I can use my HDB home as my adress right (which will just serve as my "Office Address"...???

3. By applying for my home to be my office address, will the type of business matter??? if the business that i am venturing on is importing and selling it here (what do you actually call that, trading? Mechandising? or what?) will that contradicts to the requirement of having your home under Home Office Scheme?? What i mean i want to use my house as the office address, by the business that i am applying is into retail - not allowed under HOS (of course selling it not in my house but other place)

4. But in terms of bringing in to singapore the products...and let's say it is in Bulk...i cannot really deliver those to my HDB house as that leads to a different approval for safety blah blah blah. So meaning i will register my home as the office address, but warehouse will be rented, and selling it of course in another place...
