Not Submitted
All new expense items that require manual approval start in the Not Submitted state. This simply means that the item has been created but has yet to be submitted for approval. When an expense item is in the Not Submitted state, the expense amount will be shown within a gray status oval.
Pending Approval
The pending approval state means that the expense item has been submitted for approval but the approver has not taken action yet. When an expense item is in the Pending Approval state, it will be shown within a yellow status oval.

Rejected
When the approver rejects an expense item, that person can provide an explanation as to why the item is being rejected. The original submitter can then make any needed adjustments to the item and resubmit it for approval. When an expense item is in the Rejected state, it will be shown within a red status oval.
Approved
If a project is set for automatic approvals, all expense items created for the project will automatically show as approved once they are saved. For projects that use manual approvals, the Project Admin will approve or reject all expenses that are submitted on the project. When an expense item is in the Approved state, it will be shown within a green status oval.
