Your Home page adapts to each user's role. Financial figures — revenue, purchases and invoices — stay visible as long as a role holds either of two permissions.
If staff members can see financial information you'd rather keep private, an owner account can switch off both permissions below. Removing only one isn't enough: the Home page keeps showing financial data until both are off.
Steps
Log in with an owner account
Go to Settings → Staff → Roles
Open the role assigned to the staff member
Untick Report → See purchases report
Untick Transactions → See invoices
Save
The staff member will see the change the next time they log in.
Good to know
Permissions are set at role level, not per user — every staff member assigned to that role is affected.
If one person should keep financial visibility, create a separate role for them.
Switching these off also removes access to the purchases report and to invoices themselves, not only the Home page figures.
