# Multiple Account Management
ZonWizard manages multi-user access, so it's possible for each user to have guest access to other main accounts.
If you are an account manager or an agency, you can manage all your clients' accounts through a single ZonWizard account.
To do this, you must previously have received and accepted an [**invitation from the main account**](/user/secondary-users.md#jqf2a7ol2aun) that grants you access permissions to various tools.
Once you have permission to access other accounts, you can switch between them from the **User Menu >> Switch Account**.
From here, you can see the list of accounts to which you have access permission, and by clicking on the company name, you can access and manage the selected account.
