Multiple Accounts
A single user can have access to multiple payees or admin accounts, and conversely multiple users can have access to a single payee or admin account.
To give a single user access to an additional account, send a new invite to the same email already in the system, and they'll be given the option to link their accounts during registration.
Once linked, the user can switch between their various accounts using "Account -> Switch Account" in the nav.
For more information, see Linking and Switching multiple accounts in IC.
If you try and access a link to something related to one of your payee accounts while using a different payee account, you'll either see a permission denied error or an empty data set. If you run into this issue, make sure you're using the correct account using the Switch Account page.
