Hello there, Fernando.
I understand your concern about restricting access to your company's QuickBooks account to your work IP. It is a security measure that may require your IT team's involvement to set up.
QuickBooks Online (QBO) allows location-based access restrictions, but I recommend consulting your IT team for specific guidance. They can also help enable two-factor authentication by default for your employees.
Additionally, QBO allows you to add multiple users to access your account and work simultaneously. You can check these articles for more information:
Furthermore, if you want to add an accountant to access your file, use this link as your reference: Invite an accountant to review your books.
Let me know if you have other questions about managing user access in QuickBooks. I'm always here to help. Take care.
