How to Write a Corporate Travel Policy: A Step-By-Step Guide for Small Teams

Your CFO asks how much the company spent on travel last quarter, broken down by category. You book your own trips, approve a few others, and start digging through spreadsheets, card statements, and forwarded confirmations. The number isn't there. Nobody's been watching the trip from booking to receipt.

A good business travel policy gives you one place to see who booked, what they spent, which trips broke the rules, and which receipts are missing. Six steps build one, starting with an audit of the trips already happening and ending with an annual review against the goals you set at the start.

Audit before you write

Most first-time policies fail because people write rules before looking at the trips already happening. Before you write anything, check where the money goes and how travelers book. Pull past trip data on airfare, hotels, rentals, and meals, then look for patterns that show where clearer rules would save time and prevent rejected expenses.

Four things deserve a close look. First, sort spend by category so you can see which line items are eating the budget. Then map trip volume and patterns, especially frequent last-minute bookings and common destinations. Next, find where people book and measure leakage, the industry term for bookings made outside approved channels. That off-channel spend stays hidden from finance until someone submits an expense report.

Find your biggest compliance gaps. If most overspending comes from late bookings, set advance booking rules before you tighten hotel caps.

Define two or three measurable goals before drafting

Pick two or three specific, measurable goals before you write a single rule. Your goals decide which sections matter most. Vague intentions like "control travel spend" produce vague policies. A goal like "raise booking-channel compliance from today's baseline to a defined target" tells you exactly what to build.

Ground cost-savings goals in real numbers. 78% of travel buyers cited cost control as a top strategic priority. A cost-savings goal tells you which choices need guardrails: preferred vendors, advance booking rules, per diem rates, and cabin rules. If compliance is the goal, require travelers to book in the approved tool. Show who approves exceptions and how to ask before they buy. For booking-channel compliance, measure the share of trips booked through the approved tool so you have a concrete baseline and target.

Add traveler satisfaction as a third goal when it shapes the choices travelers make before they book, like cabin class and hotel or meal limits. Whatever two or three you pick, write them down. Step 6 measures the finished policy against these exact numbers.

Six sections every corporate travel policy needs

Draft the sections travelers need before they book and after they get home. Three of them do most of the work, so they get the detail below.

Scope and booking channel

Write this section so anyone booking a trip knows when the rules apply and where to book. Apply the policy to employees, contractors, executives, and anyone else spending company money on work travel. Define qualifying travel too: client meetings, conferences, training, and site visits qualify; commuter travel to a regular workplace does not.

Name the approved booking channel and require it. If you use an online booking tool, or OBT, travelers book there. Requiring the OBT gives the company visibility when travelers are on the road: if travelers skip the OBT, the company may not be able to find them in an emergency. Then spell out exceptions for real edge cases like centrally booked conference lodging. Fast exception handling keeps people using the OBT because they don't have to guess what to do when a trip doesn't fit the normal rules.

Spend limits and per diems

Give travelers the limit before they book by writing specific numbers. Only 30% of companies set hotel per diems or rate caps, while 46% tell employees to book "reasonably priced" hotels, and that vagueness drives policy misses. Set separate limits for breakfast and lunch. Set a dinner limit too, instead of a fuzzy "reasonable meal cost." If you need a first draft, a ready-made policy template can give you those starting points.

For a domestic benchmark, anchor to GSA per diem rates, the daily allowances the federal government sets for its own travelers. For FY 2026, the standard CONUS rate is $110 for lodging and $68 for meals and incidentals, or $178 combined per day. GSA rates give you a defensible, city-specific starting point. For cabin class, default to economy and exclude first class. Allow business class only on flights over six hours with manager approval.

Approval workflow and expense submission

Make the approval rule obvious before someone books. Name who signs off, when approval happens, which trip-cost thresholds trigger the next approver, and how out-of-policy bookings route before confirmation. Set thresholds like $500 and $2,500, with $10,000 requiring the highest approver as the amount gets higher. Once you set those thresholds, decide whether approval happens before the trip or during expense review. If a booking breaks policy, route it to the right approver before the traveler confirms it.

Once the trip is booked, the same section should tell travelers how to get reimbursed. Submit expenses within the IRS 60-day rule after payment. Miss that window and payroll has to treat the reimbursement as taxable wages. Keep receipts and other receipt records for expenses of $75 or more, and always keep lodging receipts.

Make the policy visible at the moment of booking

Put the policy where the booking decision happens: next to the fare or room rate, inside the booking flow, with clear within-policy and out-of-policy indicators. Travelers make the choice in the booking flow, so keep your rate caps there too and check them against current GSA data on the GSA update cycle. A separate file hides them from the decision. Blocking options without explanation or hiding fares trains people to search elsewhere.

Back that up with a one-page summary of your core rules linked to the full document for exceptions.

A booking tool matters when travelers otherwise book in one place and check policy somewhere else. Otto the Agent is a lightweight and free TMC for growing companies without one. It reads your travel policy and shows "within policy" versus "out of policy" indicators with explanations while a traveler picks a flight or hotel in Slack, email, or SMS. For a company without a booking platform, that catches policy issues before they become expense-report problems weeks later.

Communicate it like it's new every time

A policy only works if travelers see it before they need it and understand why the rule exists. Send the policy to new hires and repeat it before annual updates take effect. When a rule changes, flag the change before travelers book under it.

• Integrate it into onboarding. Introduce the policy in a new hire's first weeks. Frame it as the way the company keeps trips inside budget and gives itself a way to find travelers during disruptions.
• Give managers an exception script. Managers need a clear, consistent response to non-compliant bookings. Silence, or inconsistent enforcement, teaches people the rules don't matter.
• Re-communicate annually when the policy updates. A short refresher for existing employees reinforces the standards and shares what changed. Communicate changes before they take effect.
• Make it findable at the moment of need. Use email, the channel travelers already know. Keep the current policy summary somewhere a traveler can reach in seconds.

Review annually and measure against goals

Policies go stale as rates drift and offices open in new cities. Last year's caps can stop matching this year's market. Review the policy at least once a year. Then measure it against the exact goals you set in Step 2.

Start by comparing your rate caps with current market data. Check whether airfare and hotel trends have moved past your thresholds, then compare them with the latest GSA rates. Treat a persistently low booking channel compliance rate as a policy or tool problem. Track where exceptions pile up by category, because a high exception rate may mean the policy is too restrictive rather than that travelers are gaming it. Watch for approval bottlenecks too, since slow approvals push travelers off-channel in the first place.

You need trip and receipt data to measure any of this. After you book, Otto stores receipts for trips booked through Otto and gives travelers expense-ready PDFs with full receipt details for accounting.

Write the policy after the audit

Opening a blank document and writing rules first feels natural, but the spreadsheet problem at the start shows why that fails. Your past trips already show which rules travelers need and which numbers will hold up. They also show where visibility breaks between booking and receipts.

Otto gives growing companies a lightweight TMC without the contracts, minimums, or implementation fees. It applies your travel policy while travelers pick flights and hotels in Slack, Teams, or email, then keeps receipts for trips booked through Otto and gives travelers expense-ready PDFs with full receipt details for accounting. No contract, no commitment, free to try.

Start with Otto to apply your travel policy before trips turn into reimbursement problems.

Frequently asked questions

What should a corporate travel policy include?

Cover scope, the required booking channel, spend limits and per diems with specific numbers, cabin rules, and the approval workflow with dollar thresholds. Include expense deadlines and receipt requirements, and duty-of-care information.

How long should a corporate travel policy be?

Short enough that people read it. Keep a one-pager of core rules for daily use and a longer document for exceptions.

How do I get employees to follow the travel policy?

Put specific rules in the booking flow and handle exceptions quickly. Apply consequences consistently regardless of seniority.

How often should a corporate travel policy be updated?

Review it at least once a year, with lighter quarterly check-ins on booking data and market rates. A merger can trigger an out-of-cycle update. So can a new office or a change in tax law.

What if we don't have a booking tool or TMC?

Growing companies without a TMC can use Otto the Agent, a lightweight free option that reads your travel policy and shows within-policy versus out-of-policy indicators while travelers pick flights and hotels in Slack, Teams, or email. Otto also stores receipts for trips booked through it and gives travelers expense-ready PDFs, so finance has the trip and receipt data needed to measure the policy against your goals.
