Using Client View allows you to share a Reports screen URL with your client, letting them view MinuteDock reports of time logged against them in your account.
They won't be able to see any billable value/charge rate information, but they will be able to report on any hours logged and the different Projects/Tasks that time is recorded against.
If a client only wants a periodic timesheet rather than live access, you can export a Report as a PDF and send that instead. See Export a Report as a PDF.
