When your invoice is ready to be reviewed by PGE, click the Submit Invoices button on Work Order header tab. Doing so will open the submit dialogue for all invoices on current work order. Verify all required documents have been uploaded, click the Edit to enable the check boxes, then click the "Submitted" checkbox next to invoice(s) you want to submit.
Click Save button to save your changes. You are asked to confirm (see message below) and submitted invoices will be marked as "Pending Review". That indicates to PGE that the invoice is ready to be reviewed for payment and the invoice can no longer be edited by the user. Once submitted, you have a brief period of time (currently 24 hours) where you are allowed to un-submit the invoice as long as PG&E has not started the review process, which will allow you to make additional changes to an invoice.
If you wish to make edits, as long it has been less than 24 hours since invoice was last submitted, and the review process has not been started by PGE, you can unsubmit the invoice by un-checking the Submit to PGE checkbox, make any desired changes, then click Submit to PGE again.
