receipts, both from the point of view of international travel, and also

    considering the fact that the person reimbursed may seek reimbursement in

    a different currency than the native currency of the organization's.

  * Track approvals of the expenses by multiple parties.  (For example,

    perhaps a volunteer project leader must approve, and then later by with

    fiduciary duty to the organization itself).

  * Ideally, the system would auto-detect any places where a travel and/or

    reimbursement policy for the organization is violated (or mandates

    additional approvals).

  * Ideally, the system could "set up" accounting entries for "merger" into

    the accounts, based on an expense report submitted, via some

    [[draft transacting approval process|DraftTransactions]].

## Reimbursement: The Traveler's View

From traveler's/reimbursement-requester's view, they'll need:

  * An easy, outward-facing web interface for submitting receipts.

  * Ideally, flagging them when additional approval is needed before

    submitting their expense report, so that they can seek additional

    approval before submitting.

  * Updates on the external web interface system about status when the

    expense is moving through the internal system at the organization. 

  * Automatic calculation of any per-diem allowances.
