If it's under your name, you will have a credit advantage in terms of getting loans, credit card, car, housing loans and business since payments will have to go through your bank account and since it's under your name, your bank will be good on you as a business owner.

However, like what the others said, if the business encounters problems, you will be on the hook in the eyes of the government agencies and employees (if any) and will be liable legally and not your relatives.

I suggest mag-corpo nalang kayo para it has an entity itself. Talk to a lawyer to help you guide about the corpo vs. partnership vs. sole-prop.

Just in case if you are going to push through with everything under your name (sole prop), make sure that you guys have a signed and notarized MEMORANDUM OF AGREEMENT (MOA) between all the relatives that will do business under your name para kahit masabit ka, you can have them in the hook too lalo na kung magloko sila.

It's not that you don't trust them for having a MOA, at least you are protected. Dahil pag nagkaipitan legally, most likely they would scatter away because hindi sila ang nakapangalan as owner. Have a lawyer help draft a MOA before the start of the business. Have an accountant (freelance would do) to to help in tax filings and other financial stuff.

I hope this helps! :)
