What is necessary to assign staff to work on clients in Xero HQ?

To effectively assign staff to work on clients in Xero HQ, it's essential to set up their user roles and permissions. This process ensures that each staff member has the appropriate access levels and rights required for their specific tasks and responsibilities within the platform. By configuring user roles, you control what actions staff members can perform, which clients they can access, and how they can interact with client data. This is vital for maintaining security and ensuring that staff members can work efficiently without unnecessary barriers.

While adding them as collaborators, providing training materials, or creating registration forms can be part of the onboarding process or enhancing collaboration, they do not directly establish the necessary framework for assigning staff to client work within Xero HQ. The setting of roles and permissions is fundamental for operational functionality and compliance with privacy standards, which is why it's the correct answer in this context.
