# Timesheet Submissions

Timesheet Submissions hold a set of time entries for a specified week, and can be approved, rejected,
or canceled.
You can enable timesheet submissions and approval in your
[project settings](https://knowledge.kantata.com/hc/en-us/articles/204346530#Financials).
Once enabled, time entries must be approved through a Timesheet Submission before it is invoiceable.
**Note**: Each Timesheet Submission can only be associated with a single project. So when a timesheet
is submitted through the UI with time entries for multiple projects, a separate Timesheet Submission
object is created for each project in the backend.
This section contains endpoints to approve, reject, or cancel a single timesheet submission.
To approve, reject, or cancel multiple timesheet submissions at once, see
[Timesheet Approvals](/tag/Timesheet-Approvals), [Timesheet Cancellations](/tag/Timesheet-Cancellations),
and [Timesheet Rejections](/tag/Timesheet-Rejections).
