Corporate Travel and Expense Management Best Practices

Travel and expense is usually one of the larger controllable costs a company has, and the policy governing it is usually the least read document in the business. Here is how to write one people follow.

Set clear goals: Decide what the policy is for before you write a line of it.
Simplify the language: If people cannot understand it, they cannot comply with it.
Cover the whole process: Approvals, booking, receipts, reimbursement.
Make it readable: Lists, tables and headings beat paragraphs.
Account for what travellers need: A policy that ignores reality gets ignored back.
Use worked examples: Show an allowed expense and a rejected one.
Plan for exceptions: They will happen; decide in advance who approves them.
Review it annually: Rates, routes and rules change.
Use technology: Software enforces policy more consistently than a manager does.
Automate approvals: Route by amount and category rather than by habit.

Two authoritative references worth having open while you write. If you are a US employer, the IRS Publication 463, Travel, Gift, and Car Expenses sets out the accountable plan rules and what counts as adequate substantiation — get this wrong and reimbursements become taxable wages. And the GSA per diem rates give published, location-specific lodging and meal allowances for the federal fiscal year. Private employers are not bound by them, but they are a defensible starting point for your own limits and they are updated every year, which your policy probably is not.

1. Define Clear Objectives for Your Travel and Expense Policy

Decide what the policy is supposed to achieve, because the answer changes what you write.

A spending target

A specific reduction, in currency or percentage, against a measured baseline. “Reduce travel spend” is not a target.

Visibility

Knowing where the money goes, by department, by trip type, by vendor. Most companies discover the answer is not what they assumed.

Compliance

A higher share of expense reports that arrive complete and within policy, which is mostly a design problem rather than a discipline problem.

Less administrative work

Fewer hours spent booking, chasing receipts and reprocessing rejected claims.

Accountability

Clear ownership of company money, and clear consequences when it is misused.

2. Simplify Language for Better Understanding

Write it so a new joiner can act on it without asking anyone:

Plain words. Avoid legal and accounting terminology where an ordinary word will do.
Define the terms you cannot avoid.
Use bullets for rules and tables for limits.
Translate it if your team does not all share a first language.
Name the person to ask, with contact details.

Practical writing rules:

Keep sentences short — under twenty words is a reasonable ceiling.
Say what is allowed, not only what is forbidden.
Break long sections into short ones.
Check readability with a Flesch Reading Ease score if you want a number on it.

The test is not whether the policy is complete. It is whether someone standing at a hotel desk can work out what to do.

3. Comprehensive Guidelines on Travel and Expense Processes

Travel approvals

Who approves what, and above which value.
How long approval should take, so people can plan.

Booking procedures

Which booking channel or agency to use, and whether it is mandatory.
Rules on cabin class, hotel tier and car category.

Expense reimbursement

What is reimbursable and what evidence is required. US employers should align this with the substantiation rules in IRS Publication 463 rather than inventing their own.
The submission deadline after a trip, and what happens if it is missed.

Spending limits

Daily limits for meals and incidentals. GSA per diem rates by location are a defensible basis for these.
Caps on airfare, lodging and car hire.

Payment methods

When to use a corporate card, when to pay personally and claim, and when an advance is available.

Expense reporting

Required detail, receipts and business purpose for each item.
Automatic card feeds where available, which removes most manual entry.

Policy compliance

State that compliance is required and what happens when it is not met. A policy with no stated consequence is guidance.

Travel safety

Where to check destination risk information.
Whether the company runs traveller tracking, and what that means for privacy.

Preferred vendors

Named agencies, booking tools and hotel groups.
Negotiated rates only work if bookings actually route through the preferred channel, so say whether it is mandatory.

Non-reimbursable expenses

List them explicitly — typically alcohol, personal entertainment, fines, and upgrades bought at the airport.

Auditing

How often reports are sampled, and by whom.

4. Visual Clarity and Organization

Use lists. Break rules into bullets and processes into numbered steps.

Put limits in a table. Spending caps, approval thresholds and required documentation belong in a grid, not in prose. This is also the section you will update most often, so keep it separable.

Order it by the traveller’s journey — request, approve, book, travel, claim, get paid — rather than by department.

Keep paragraphs short and formatting consistent. A policy that looks maintained gets treated as maintained.

5. Incorporate Employee Needs and Preferences

A policy written purely for the finance team produces workarounds. Practical accommodations:

Ask frequent travellers what actually causes problems, and fix those things.
Accommodate disability, dietary and medical requirements explicitly rather than case by case.
Set meal and incidental allowances at a level that covers a real meal in the destination city. Per diem tables exist precisely because a single national figure does not work.
Decide your position on personal loyalty points and write it down, either way.
Cover the small unavoidable costs — baggage fees, in-transit connectivity, tips where customary. Refusing these produces padded claims elsewhere.

6. Use Real-World Examples

Examples do more work than rules. Include a couple in the policy itself.

Show an allowed expense and a rejected one. For instance, a modest dinner on a two-day trip is reimbursable, while a bottle of wine charged to the same bill is not. Use your own figures here — the amounts in your policy should come from your per diem table for the destination, not from an example in an article.

Show how an exception works. For example: alcohol at a client dinner may be reimbursable with prior written approval from a named approver. Say who that is.

Circulate a compliant expense report with personal details removed, so people can see what “complete” looks like.

Show a compliant itinerary for a typical trip — the flight, the hotel tier, the ground transport.

An earlier version of this article gave specific dollar amounts for a compliant dinner and a rejected bottle of wine. They were invented for illustration and read as though they were recommended limits, so they have been removed. Your limits should come from your own policy table.

7. Cover Special Situations and Policy Exceptions

Premium cabin travel

Many policies permit a higher cabin class above a defined flight duration. Pick a threshold, write it down, and require prior approval. The threshold is a business decision, not a standard.

Last-minute travel

Define a fast path for urgent trips, accepting that fares will be higher, and who can authorise it.

Travelling with family

State clearly which costs the company covers and which it does not.

Medical emergencies

Explain what happens if someone is injured or falls ill while travelling, including who to call first.

Approving exceptions

One route, in advance, in writing. Retrospective approval is how policies erode.

Reviewing exceptions

If the same exception is granted repeatedly, the rule is wrong. Change the rule.

8. Regular Policy Revisions

Review annually

Book the review. Per diem tables, tax guidance and negotiated rates all change on their own schedule.
Check the policy still matches how the business travels.

Watch the exceptions

Frequent breaches usually indicate a rule that is unworkable rather than a workforce that is careless.

Ask travellers

Anonymously. People will not tell finance directly that the claim process is painful.

Involve the right people

Finance, the travel booker, and at least one person who travels every month.

9. Use Technology for Policy Compliance and Efficiency

Software enforces a policy more consistently than a manager reviewing receipts at month end.

Automate expense reporting. Tools including Expensify, SAP Concur and Emburse Professional build expense reports from corporate card feeds and receipt capture, which removes most manual entry.

A note on names, checked August 2026. The product formerly sold as Certify is now Emburse Professional. It was acquired and rebranded first to Emburse Certify and then to its current name. If “Certify” appears on an old shortlist, that is the product it refers to. Concur is properly SAP Concur, following SAP’s acquisition of Concur.

Route approvals automatically. Reports go to the right approver by rule, with out-of-policy items flagged rather than found later.

Enforce policy at the point of booking. A booking tool that knows your rules prevents the problem instead of reporting it.

Give finance current numbers. Committed and actual spend against budget, during the period rather than after it.

Pay by direct deposit. Faster for the employee and cheaper to process.

Pricing. Expense management tools are typically priced per active user per month, sometimes with a minimum monthly charge, and some vendors quote only. Several charge only for users who actually submit in a given month, which changes the comparison considerably at low volumes. This article does not publish rates, because they vary by contract and change; get quotes and normalise them to your own number of monthly claimants.

10. Automate The Approval Process

Set workflow rules

Route by role, amount and expense category, automatically.

Allow mobile approval

Approvals happen between meetings or not at all.

Use thresholds

Auto-approve low-value in-policy items; reserve human review for the amounts that justify it.

Require a comment on rejection

An unexplained rejection gets resubmitted unchanged.

Allow delegation

Approvals should not stop because one manager is on leave.

Measure approval time

Slow reimbursement is the most common complaint travellers have, and it is measurable.

Integrate travel and expense systems

Link booking, cards and expense reporting so the data arrives already matched.

Conclusion

A travel and expense policy fails in one of two ways: it is so loose that spending drifts, or so tight that people spend their time working around it. Both are design failures.

What to get right:

Define the goal before writing the rules.
Write plainly, and put the limits in a table you can update on its own.
Base limits on published references such as GSA per diem rates rather than on a number someone remembered.
Follow the substantiation rules that apply to you — for US employers, IRS Publication 463.
Decide the exception process in advance, and review the exceptions annually.
Automate booking checks, routing and reimbursement.
