Can contractors track time without seeing my clients or invoices?

Yes. The contractor role can track time on the projects they're assigned to, but permission walls stop them there. Contractors see only their own projects and time — never your client lists, your margins, or your invoices.

So you can bring in extra hands for a busy month, have their hours flow straight into your billing, and keep the commercial side private. Their rate is set per project-member, snapshotted at entry time, and rolls into your invoices — without exposing what you charge the client. See security.
