A: Each workspace is completely separate — data from one workspace is not visible to members of another. So your different businesses are kept private and confidential from each other by default.

When inviting team members, you simply invite them to the specific workspace(s) they need access to. If someone needs access to more than one workspace, they can use the same login and switch between workspaces — but they'll only ever see the ones they've been invited to.

On top of that, within each workspace you can also control exactly what each person sees using Permission Sets — for example, restricting a member to only the CRM, Projects, or Field Service module.

So in short:

✅ One purchase with multiple workspaces (available from Tier 4 onwards)
✅ Invite each employee only to the workspace relevant to them
✅ No cross-workspace data visibility
✅ No need for separate purchases or different email addresses
