After invoicing, timesheets are locked. If you run travel after invoicing, mileage expenses and travel time won't apply unless a system setting is turned on.
You can avoid this by running travel before invoicing, or by enabling a setting that allows edits after invoicing.
To enable editing after invoicing, follow these steps:
Click Setup.
Click System.
Click Timesheet.
Select the Allow timesheet editing after invoicing checkbox.
🤓 Tip: If payroll has already been run and timesheet editing is no longer needed, clear this option again in Setup.
Click Save changes.
