What info is required to add staff in quick book?

A pleasant day to you, @malichowhan.

If you're referring to adding an employee in QuickBooks Online, the information that you need are the following:

• Personal Details
• Employment Details
• Banking Details 
• Tax File Declaration Details  

To give you the complete details of the payroll set up, I recommend checking out this great resource: How to set up an Employee in QuickBooks Payroll.

However, if you're referring to adding a user in QuickBooks Online, you need to prepare is a valid email. The added user will receive an invite from QuickBooks so they can set up their credentials.

For more information about the different types of users in QBO and on how to add them, please see these links:

• Add, delete, or change user access
• User types in QuickBooks Online

You can always find me here if you have any other questions. I'll make sure you're all set. Have a lovely evening!
