Each mobile app user should close out the day by Approving the day's Time Sheet(s). This lets the back-office personnel know that no additional changes will be expected from the mobile user.
If the Company Settings do not require signatures, Time Sheets can be approved by simply tapping the End of Day or Approve button (single mode) or by selecting all workers then tapping the Approve button (crew mode) as illustrated below.
If Company Settings do require signatures, open the Employee Time Sheet for each worker and tap the Approve button to display the Employee Time Sheet Approval screen. As illustrated below, the employee can review the information and provide a hand drawn signature.
