Hello and welcome to the Community, talitaribeiro.
When applying for QuickBooks Payments, you'll be asked to provide a Social Security Number. The person who's number is entered on the application will be listed as the principal on the merchant account. Each account requires a personal guarantor who will be financially responsible for it, if approved.
Many things go into this process. Since you don't have a SSN, I recommend contacting us so that an agent can go over all of the available options with you.
You can find further information about using an Intuit merchant account here: Intuit Payments Merchant Agreement
If you have any questions, I'm just a post away. Enjoy the rest of your day!
