Xero's accounting software lacks granular permission controls that would restrict users to only specific client accounts rather than granting access to all accounts.

AccountGuard Permissions Manager

A permission management layer that integrates with Xero to provide granular, account-level access controls for multi-client accounting firms. It sits between users and Xero's API to filter access based on customizable rules, giving firm owners precise control over who can see which client accounts without requiring Xero to change their core platform.
