The mobile app will provide you a section to edit and review your DRAFT and NEW expenses. You may also view your APPROVED and PAID expenses here as well.
To get to the expenses listing page, tap "Expense" on the bottom of the screen, then tap "Expense" in the tabs at the top of the section screen. This will bring you to a screen that looks like this:
From this list view, you can access edit, submit and delete actions for DRAFT expenses by swiping left on DRAFT expense you wish to make the action against.
To review any expense on the list page, simply tap on the expense item you wish to review. Doing so will bring you to the expense detail screen.
To submit a DRAFT expense from the detail screen, tap the "Submit Expense for Review" link or icon at the top of the screen.
If you wish to edit a DRAFT expense, click on the orange "Edit Expense" link at the top of the general info section. This will bring you to the expense form to make edits. You'll be able to submit for review or save as DRAFT again from that form. Only DRAFT expenses may be edited.
You may upload a receipt against submitted expenses by scrolling down on the detail page and tapping on the "Add Receipt" link and icon. This will give you the option to take a picture of your receipt or upload it from your camera roll.
