Approval Delegation for Employee Expenses

Approval delegation is a temporary assignment that keeps an expense review moving when the usual approver is unavailable. It should transfer only the decision authority the organization has explicitly assigned, for a defined period and scope. Delegation is not a way for an employee to approve their own expenses, bypass another required reviewer, or assume that a substitute has the same authority as the normal approver. This workflow focuses on setting up, using, and closing a bounded delegation.

Define the delegate's authority before the absence

Document who is delegating, who will act, the start and end dates, the employee groups or expense types covered, and any amount or category restrictions established by internal policy. State which review duties transfer and which stay with finance, a budget owner, or another designated role. Confirm that the delegate is not the claimant and has enough context to evaluate business purpose and policy. If the organization requires advance authorization for the delegation, obtain it before the handoff begins.

Keep the evidence and approval trail together

The delegate needs the same case evidence the normal approver would review: a business purpose, transaction date and amount, receipt or other required supporting record, relevant policy context, and any prior authorization. The approval record should identify the delegate acting under delegated authority, not suggest that the regular approver personally reviewed an item they did not see. Note questions asked, corrections requested, decisions made, and any referral to another role. Avoid forwarding unrelated employee or financial information simply because it is available.

Separate routine review from decisions outside scope

A delegate can resolve only cases within the written scope. An unusual policy exception, a conflict of interest, a disputed amount, or an expense beyond stated authority should follow the organization's escalation route. The delegate should not broaden their own assignment to clear a backlog.

Worked example: manager on planned leave

A team manager will be away for one week. Before leaving, the manager requests a named colleague as temporary reviewer for routine employee travel expenses during those dates. The organization's designated owner confirms the assignment and scope. A traveler submits a report with an itemized lodging receipt and a stated project purpose. The delegate checks the dates against the trip context, confirms the documentation is present, and records approval under the temporary assignment. A second report includes a charge the employee says was unavoidable but does not explain; the delegate returns it for an explanation rather than treating coverage as permission to waive the rule.

Close the handoff and correct misrouted items

At the end date, restore the usual routing and give the regular approver a concise handoff of unresolved cases, decisions needing follow-up, and any material exceptions. Check that submissions after the end date were not still routed to the delegate. If an expense was approved by someone outside the assignment's scope, preserve the original record, notify the authorized owner, and obtain a documented review or correction; do not erase the history or backdate a replacement decision.

1. Set the assignment's owner, delegate, scope, and dates.
2. Confirm all other required approval layers remain intact.
3. Review each case against the same policy and evidence standards.
4. Escalate out-of-scope decisions and close the handoff on time.

For recurring absences, examine whether the coverage plan is clear and whether the substitute has the appropriate organizational authority. Changes to roles or reporting lines should trigger a fresh confirmation, not an assumption that an old delegation remains valid.
