# Approve and lock timesheets

**Category:** [Time Tracking](https://help.totalctrl.app/hc/totalctrl/totalctrl-help-center/en-US/categories/time-tracking)
**Updated:** 2026-08-19

Approvers and admins review submitted weeks under *Time Tracking → Approvals*.
## Review

Each row shows the person, the period, total hours, and billable hours. 
## Approve or return

- **Approve** — the timesheet is accepted and its entries lock (become read-only). Approved billable time is now eligible for invoicing.
- **Return for changes** — send it back with an optional reason. Entries unlock so the person can fix and resubmit (already-invoiced entries stay locked).

## Notifications

Submitters and approvers are notified at each step, and every transition is written to the Audit Log.
