If you are one of the primary rate card approvers (a permission set by the site administrator via Application Administration | Firms & Vendors | Set Rate Card Approvers) you have the option to approve all timekeepers' rate cards at once.

To approve all rate cards for a firm's or vendor's timekeepers simultaneously, go to the Staff tab within a firm's or vendor's profile page, then click the Approve All button, located above the staff list. When the confirmation prompt appears, click OK. Rates are approved immediately, and a new notification is displayed.
