Expense Management Best Practices

Strong expense management is the result of clear expectations and dependable follow-through, not the largest number of rules. Practices should make appropriate spending straightforward, give reviewers enough information to exercise judgment, and create a record that accounting can trust. The following principles work best when adapted to actual purchasing patterns and revisited as the organization changes.

Write rules people can apply

Describe allowable business purposes, required evidence, approval responsibilities, and how employees should handle unusual circumstances. Replace ambiguous instructions such as “reasonable” with context and examples that help someone decide what to do. Explain whether approval is needed before a commitment or only during expense review. Keep the policy, submission form, and manager guidance aligned. When employees ask the same question repeatedly, treat it as a signal that the instructions or workflow may need improvement.

Make documentation timely and meaningful

Ask employees to record the purpose while details are fresh and submit receipts or other evidence through a consistent channel. A receipt shows transaction details but may not explain why the purchase served the business. Require a concise business description and, where useful, attendee, project, or trip context. Establish an alternative procedure for unavailable documentation instead of encouraging employees to invent or omit information. Clear records help approvers and accounting without asking for irrelevant narrative.

Use review roles deliberately

The employee can attest to the facts; the manager can judge business context and budget fit; finance can apply policy, coding, and control knowledge. Assign each check to the person best positioned to perform it. Set backup owners and escalation paths so submissions do not stall when one approver is away. Train reviewers to explain a return with a specific next step. Periodically compare how different reviewers handle similar cases to find inconsistent interpretations.

• Separate authorization from after-the-fact review where the risk warrants it.
• Use the same criteria for comparable transactions and record exception reasons.
• Reconcile card activity and reimbursement records rather than relying on approvals alone.
• Limit access to financial and employee information to appropriate roles.
• Review recurring exceptions and update guidance instead of repeatedly correcting symptoms.

Choose useful measures

Track process quality, not just volume. Aging submissions, repeated corrections, unresolved exceptions, and time to complete review can point to unclear ownership or poor instructions. Pair operational measures with periodic sampling for documentation and coding quality. A low return rate is not necessarily a success if reviewers are overlooking issues, and a fast payment metric is not useful if reconciliation remains incomplete. Define what each measure means before comparing it over time.

Treat improvement as routine work

Ask employees, managers, and accounting staff where the process creates confusion. Use examples to test proposed policy changes: can a new employee tell what to do, can a manager explain an exception, and can accounting trace the final decision? Introduce changes with a short explanation and update associated forms and training together. A regular review keeps the process responsive without changing rules so frequently that employees cannot rely on them.
