A corporate or LLC structure is certainly the way to go, but sbunny8 is actually understating the importance of a personal guarantee. It’s not a matter of a few percentage points. A new small business with no collateral will not be able to set up so much as the utility bills without being personally liable. Leases and loans almost always hold the owner responsible.
Which is not a reason to avoid the LLC setup - might as well give yourself at least the possibility of limited liability - but an owner in this kind of scenario should plan on having to repay everything personally.
