Seven questions. One honest answer.

Where do you live?

We use this to flag states that force you to register twice and to sort out foreign-qualification cost before you file.

Where will the business actually operate?

Not where you want to "form in Delaware" for prestige — where your customers, contracts, or physical location are.

What do you expect in your first 12 months of revenue?

Are you planning to raise from venture capital?

How many people are involved?

What kind of assets will the business hold?

How much personal-liability risk are you comfortable with?

A sole prop is free but exposes your savings. An LLC puts a wall between you and a bad contract.
