Travel Management Company Fees: What You Are Billed For, Line by Line

A quote lands from a travel management company and there are six lines on it. One is a percentage. One is per person per month. One is a one-time number with the word onboarding sitting next to it. One is a minimum. Meanwhile you are trying to answer one plain question, which is what this costs us next year, and travel management company fees are not written to answer it.

I’m Nir Sabato, co-founder of Catch. Catch is an AI executive assistant with supported business flight and hotel booking in beta for eligible customers, so I spend a fair amount of time reading how the rest of the market charges for the same job. Travel management company fees are built from six separate structures, each priced on a different thing, and almost no quote names all six.

Here is each one in turn: what the fee pays for, when it starts to hurt, and a worked example at the end showing which one actually dominates your bill at ten trips a year versus three hundred.

The six fee structures behind travel management company fees

Fee	Priced on	Gets expensive when
Transaction or booking fee	Each booking or trip	You travel often, book cheap tickets, or change plans
Subscription	A seat, a company, or a report	You pay for people who rarely travel
Implementation and onboarding	One time, at the start	You sign a short contract or switch providers
Support surcharge	Each assisted or after-hours interaction	Trips move, which they do
Supplier markup and commission	Invisible, built into the rate	Never shows on your invoice at all
Minimum spend or volume	The gap between your travel and the floor	Your program is smaller than the contract assumes

Everything that follows is one of those six rows.

1. The transaction fee, charged per booking

This is the fee most people have in mind when they say corporate travel agency fees: a charge bolted onto the act of booking. It might be a flat dollar amount per ticket, the way traditional agencies have always quoted it, or a percentage of the booking value, which is the newer platforms’ habit.

TravelPerk, which rebranded to Perk in November 2025, publishes this one openly. Its travel-only plans for North America pair a platform fee with a cut of every booking: Starter at $0 a month plus 5% per booking, Premium at $99 a month plus 3%, and Pro at $299 a month plus 3%.

A percentage and a flat fee pull in opposite directions, and that matters more than the headline number:

• A flat fee per booking bites hardest on cheap tickets. A $45 transaction fee on a $180 regional flight is a quarter of the fare. On a $1,400 transcontinental business fare it rounds to nothing.
• A percentage does the reverse. Painless on the short hop, and it climbs with every expensive long-haul ticket you buy, without anyone at the agency doing a minute of extra work.

Two questions decide what you actually pay here, and the quote rarely answers either. Ask what counts as one booking, since a trip stitched together from a flight, a hotel and a car might be billed as one transaction or as three. Then ask whether a change re-triggers the fee. A rebooked flight is frequently a new transaction at full price, and on a program where plans move, rebookings are not an edge case.

2. The subscription, priced per seat, per company, or per report

The second structure recurs whether or not anyone leaves the office that month. The unit is where providers diverge hardest, and it is the reason travel management fees resist comparison.

Per company. TravelPerk’s $99 and $299 travel-only platform fees attach to the account rather than the headcount, so the platform fee itself does not move when you add an eleventh traveler.

Per user per month. Navan prices its expense product this way: free for the first 5 monthly expensing users, then $15 per user per month. Its business travel booking carries no platform fee on the Business tier, and Navan states that its travel business is funded by travel providers’ commission fees. The Enterprise tier is quoted rather than published.

Per report. Concur publishes per-report pricing with unlimited users, at roughly $7 per expense report on Base and roughly $11 on Plus, with Premium at custom pricing. Worth knowing before it reaches your shortlist: Concur Travel appears only in the Premium tier, so the two self-serve tiers are expense products.

Per member. Ascend, a messaging-based travel concierge, charges a membership instead: $300 per month or $2,500 per year for an individual. Ascend says it does not charge routine booking, service, change or cancellation fees, with handling costs possible in a small number of edge cases such as certain low-cost carriers or complex changes on heavily discounted premium fares.

Four real figures, describing four different things. Drop $15 next to $7 in a spreadsheet column and you get a confident, wrong answer, because one is charged per user per month above a free allowance and the other per report filed with unlimited seats. The only honest way to read a subscription fee is to model it against last year’s actual activity: how many people travel, how often, how many reports they file.

Where this one gets expensive is predictable enough. A per-user price climbs with the number of people who touch the system each month, so the unit you are billed on is the first thing to pin down. Per-report pricing climbs with the number of reports your travelers file, which is why a program of small, frequent claims costs more than its travel budget suggests.

3. Implementation and onboarding

A one-time charge, billed before anyone has booked a single trip. It covers account configuration, loading your policy and cost centers, connecting your accounting system, data migration, training sessions.

Nobody in this market publishes a standard number, and plenty of providers fold setup into the subscription instead. Some travel platforms do charge a mandatory one-time onboarding fee, so ask outright rather than assuming the start is free.

Three things to pin down while it is still a negotiation:

1. Is it waived on a longer term? Implementation is the line most often discounted in exchange for contract length.
2. What happens if you leave in year one? An onboarding fee spread over three years is a different number from the same fee over twelve months.
3. Who does the work? If configuring the policy lands on your finance lead, the fee bought you a project plan and your team is doing the project.

This is also the fee that makes switching providers cost real money even when the new provider is cheaper per booking. Pay it twice in two years and it dominates both.

4. The support surcharge, which is what a change really costs

Self-serve booking is the cheap path on most published price lists. The moment a human gets involved, or the clock falls outside business hours, a separate fee tends to appear. Agent-assisted booking, offline booking, after-hours support, change and cancellation handling, refund processing: these are commonly priced individually, and they are not always inside the transaction fee you were quoted.

Which matters, because assisted support is not a luxury purchase. It is what you buy on the Tuesday night when a connection is cancelled and the meeting is at nine the next morning.

The flexibility add-on charges for the same thing up front. Rather than paying per change, you prepay for the right to make them:

• TravelPerk’s FlexiTravel option charges 10% per trip to guarantee an 80% refund on cancellations made up to two hours before departure.
• Engine, formerly Hotel Engine, sells FlexPro as a company-wide add-on at $299 per month or $2,999 per year billed annually. It lets companies cancel or modify eligible hotel bookings until noon on the check-in day, superseding the hotel’s own policy. Two details decide whether that is worth it: the value comes back as a one-year travel credit rather than cash, and coverage is not universal, so eligibility has to be checked per booking.

Both are honest products. Both are also a bet, and the bet is priced on how often your plans move. Ask for the full assisted-support fee schedule in writing, then go count how many of last year’s trips changed after booking. If a third of them moved, the surcharge line is not a footnote in your travel management company fees. It is a main line.

5. Supplier markup and commission, the fee that never reaches your invoice

Some providers charge the buyer nothing to book. Engine’s pricing page states that the platform is free, not a free trial, and its FAQ says there are no membership fees, no contracts and no minimum spend. That is genuinely free to use, with the caveat that Engine separately sells paid extras, including the FlexPro cover above and its own charge card, so not everything in the account is free.

If a platform fee is not what you are paying, the money is being made somewhere else in the transaction. Navan says so plainly: its travel booking carries no platform fee on the Business tier, and its pricing page explains that the travel business is powered by travel providers’ commission fees. Supplier-side economics are completely normal, and they are how most of the travel industry has always worked.

What it means for you is narrower than the usual scare story. Commission does not automatically make a rate worse. It does mean the fees you can see are not the whole picture, and that the thing worth auditing is the rate itself rather than the fee schedule. Pick five recent bookings, price the same room and the same flight directly with the hotel and the airline, and compare. Once a year is plenty. That comparison tells you more than any line on the invoice, and it is the only part of supplier-side economics a buyer can actually measure.

6. Minimum spend and volume commitments

The last structure is not a fee at all until you miss it. A contract sets a floor, expressed as annual travel spend or as a transaction count, and if your program lands under the floor you pay the difference anyway.

This is the single line that makes a traditional agency expensive for a company with twelve travelers rather than two hundred. Negotiated rates and dedicated service are built on volume, and the commitment is how the provider secures it.

Newer platforms often skip it, which is a genuine advantage for a mid-market program with uneven travel. Engine’s FAQ states no contracts and no minimum spend. Navan’s published pricing carries no contract minimum. If you are being asked to commit, test the floor against your worst quarter rather than your average one, and ask what happens in a year when travel gets cut.

A worked example: which fee actually dominates

Take the three-tier shape percentage-based platforms tend to publish, with round numbers so this stays a model rather than anyone’s quote: $0 a month plus 5% per booking, $100 a month plus 3%, and $300 a month plus 3%. The arithmetic below is mine. It treats the percentage as a straight percentage of spend and applies no minimum or maximum fee per booking, and providers often set both, so the point to take from it is which structure dominates, not the totals themselves.

Company A: 10 trips a year, $1,500 average trip, $15,000 of annual travel spend.

Tier	Platform fee	Booking fees	Annual total
$0 + 5%	$0	$750	$750
$100 + 3%	$1,200	$450	$1,650
$300 + 3%	$3,600	$450	$4,050

Company B: 300 trips a year, $1,500 average trip, $450,000 of annual travel spend.

Tier	Platform fee	Booking fees	Annual total
$0 + 5%	$0	$22,500	$22,500
$100 + 3%	$1,200	$13,500	$14,700
$300 + 3%	$3,600	$13,500	$17,100

The reversal is the whole point. At ten trips, the subscription is 73% of Company A’s bill on the middle tier and the booking percentage barely registers. At three hundred trips, the subscription is 8% of Company B’s bill and two percentage points of booking fee are worth $9,000 a year.

The crossover sits at $60,000 of annual travel spend, around 40 trips at this average. Below it, buy the cheapest subscription and swallow the higher percentage. Above it, pay the platform fee to cut the percentage, because the percentage is what compounds.

Two cautions before you use this as a template. Ask whether the percentage has a floor or a ceiling per booking, since a minimum fee per transaction changes the cheap-ticket end of the model quite a bit. And run your real average trip value, not $1,500: the trip count at the crossover moves with it.

What to ask before you sign

Seven questions that fill in the lines a quote leaves out:

1. What is the fee for a flight, a hotel, a car and a rail booking, each separately?
2. Does a change or a rebooking trigger a new transaction fee?
3. Is the subscription per seat, per company, or per report, and what counts as a billable user?
4. What is the one-time implementation fee, is it waived at any term, and what does it include?
5. Can I see the full fee schedule for agent-assisted and after-hours support?
6. Is there a minimum spend or transaction commitment, and what is the charge if we fall short?
7. Which of these fees is in the quote and which gets invoiced separately?

What Catch charges

Catch is a flat $99 per person monthly subscription. Supported business flight and hotel booking is in beta for eligible customers, with approval before purchase or rebooking. Fares, room charges and supplier change or cancellation fees are separate.

The Catch subscription has no separate per-booking percentage or implementation charge. That does not make the trip or a change free: suppliers may charge fares, hotel costs and change or cancellation fees. Onboarding is self-serve and takes under three minutes: connect Gmail or Outlook, and Catch works with Google Calendar or Outlook Calendar. There is a 10-day free trial.

What you get for that is closer to the travel agent itself than to a search screen. For eligible beta customers, Catch proposes supported flights and hotels using calendar and inbox context, books after approval, and helps review supported changes against availability, fare rules and supplier fees. Ground transport may need separate arrangements. It can also call the hotel about a late checkout. You reach it in Slack, email, text message, iMessage or by phone.

Three boundaries, since they are part of the price:

• Travel policy remains yours to confirm. Share your travel policy, budget and approval requirements so Catch can use them when proposing supported options. Confirm compliance before purchase; Catch does not replace a company travel-policy enforcement or approval-routing system.
• Catch does not do expense management or T&E today. No expense reports, no receipt capture, no reimbursement. Expenses are on the roadmap. Travel booking remains in beta for eligible customers.
• Business travel only. Not leisure, not family trips.

Catch is SOC 2 Type II and CASA Tier 2, with data hosted in the US.
