How to Setup Business Accounts

[Tristen M Walker]

How do you guys/girls setup your business bank accounts? My questions are:

Do i need an LLC for a business bank account?

Can i hold multiple security deposits in one account? the money wouldnt touch my personal accounts so i dont see how that would be seen as commingling.

Do you use an account for rent/repairs as a “tenants/cashflow” account and then another for YOUR business expenses like printer paper and business trips?

Im new, thanks for your help.
