Best Corporate Travel Software for Consulting

The best corporate travel software for a consulting firm is the one that tags every booking to a client or project at checkout, because a consultancy rebills a large share of its travel and every untagged trip turns into an hour of finance work at invoice time. For a US firm under 300 employees, Navan Business is the cheapest place to start, at $0 for booking. ITILITE is the strongest pick when travel is rebilled by project, at a printed $10 per trip with project level trip mapping. Perk and Engine fit firms with heavy on site hotel stays, and SAP Concur fits large firms already on an SAP ledger with a travel management company under contract. Every price below was read off the vendor's own site in October 2026.

What follows is what a consultancy actually needs from the tool, a side by side table, a short verdict per platform, and the federal per diem limits that apply when the client is the US government.

What a consulting firm needs from corporate travel software

Consulting travel is different from sales travel in one way that matters: somebody else usually pays for it. Engagement letters either pass travel through at cost, cap it at a percentage of fees, or hold it to a per diem. So the questions that decide the software are about money flowing back out, not about the booking screen.

• A client or project code captured at booking. If the code is added afterward on the expense report, someone has to chase it, and the trip that never got coded never gets billed.
• Approvals routed by engagement. The partner who owns the client should see the trip, not a general travel manager who cannot tell whether a second consultant on site was in the budget.
• Exports your billing system accepts. Travel has to reach the client invoice, which means the ledger and the time and billing tool, not just a dashboard.
• Per diem rules for public sector work. Firms with federal clients bill lodging and meals against GSA rates, so the tool has to show the cap before the hotel is chosen.
• Fast changes. Client meetings move. The platform's change process, and what it charges for it, shows up every week.

Best corporate travel software for consulting firms compared

Navan for boutique and mid-size consulting firms

Navan Business costs nothing for booking at companies of up to 300 employees, with no cap on trips, because travel provider commissions fund it. Navan describes custom fields that admins set to collect information during booking checkout and expense submission, explicitly for allocating costs to projects or clients, and Navan routes the approval to whoever is assigned to a given field response. For a consultancy that means the engagement partner can approve the trip for their own client.

The cost to watch is expense. Navan Expense is free for the first five monthly users and then $15 per user a month, so a 60 person firm where 40 consultants file every month pays $525 a month for expense alone. Navan also charges a per booking trip fee that it does not price on navan.com, so ask for it on the call. The full breakdown is in what Navan costs.

ITILITE for firms that rebill travel by project

ITILITE lists project and job level trip mapping, approval routing by project code and custom cost center fields on its pricing page, which is the closest any of these vendors comes to describing a consultancy's workflow in its own words. ITILITE prices travel at $10 per trip, or $7 when you pay from a pre-funded wallet, with expense at $6 per active user a month on annual billing.

The flat fee is the point for a firm that passes travel through to clients. A $10 charge on a $1,128 trip is under 1 percent and it is the same on a $400 domestic hop as on a $4,000 international one, so nobody has to explain a percentage booking fee on a client invoice. The yearly math at 100 to 1,000 trips, and what ITILITE counts as one trip, is on ITILITE pricing.

Perk and Engine for long on site engagements

Perk supports custom fields for project codes and client names, and Perk's pricing is a percentage of each booking. Perk Starter costs $0 a month plus 5 percent per booking capped at $30, which at normal US trip costs means a flat $30 a booking. Perk Premium costs $99 a month plus 3 percent with no cap. On a long engagement with several hotel weeks per consultant, the cap on Starter usually makes it the cheaper of the two. Details are in Perk pricing and booking fees.

Engine was built on lodging, and Engine handles the money side of a hotel stay unusually well for consulting: Direct Bill puts the room and tax on one company invoice so the consultant does not front the cost for three weeks, and job costing custom fields carry the engagement code from the moment of booking. Engine is free to the company because supplier commission pays for it.

SAP Concur for large firms on an SAP ledger

SAP Concur is the default at large consultancies for a reason that has little to do with the booking screen: Concur maps cost centers, departments and project codes onto its own fields during implementation and posts back into SAP and Oracle ledgers in a form the general ledger accepts. Concur Expense runs about $7 per expense report, and Concur Travel is quoted per trip booked and assumes a travel management company alongside it. That makes Concur the expensive and slow option for a 40 person boutique and the sensible one for a firm with several legal entities. See Concur Travel pricing before you take the call.

Billing client travel at GSA per diem rates

Firms with federal clients bill lodging, meals and incidentals against the government per diem. Under FAR 31.205-46, a contractor's lodging, meal and incidental costs are allowable only up to the maximum per diem rates in the Federal Travel Regulation, so anything above the GSA rate comes out of the firm's margin. Many state and local contracts copy the same limits.

The FY 2027 rates took effect on October 1, 2026. These come straight from the GSA per diem API:

Two details catch firms out. The first and last day of travel pay 75 percent of meals and incidentals, so $69 rather than $92 in the top tier. And lodging caps move by month, so a Boston engagement priced in a $213 month and extended into a $365 month suddenly runs over. A tool that shows the trip's cost against the cap before anyone commits to dates saves that argument.

What none of these platforms does for an engagement trip

Every platform above prices and controls the booking. None of them works out what the trip should be. On a consulting engagement that is the expensive part: which days the client workshops fall on, whether the team flies in Sunday night or Monday morning, whether a second client in the same city belongs on the same trip, and what the whole visit will cost before it goes to the partner or into the client estimate. Who goes at all is usually settled earlier, in resource and capacity planning, but the trip itself still lands on someone's desk as a blank page.

TripAgent.ai writes that plan. Describe the engagement trip in a sentence and it returns a day by day itinerary with a price on every line, so the estimate exists before the booking tool opens and the client sees a number you can stand behind. Plans start at $49 a month with no per trip or per user charge, there is a one-time demo at the top of this page, and TripAgent.ai does not book anything, so firms keep booking in Navan, ITILITE or Concur. The business travel planner page shows what a finished work itinerary looks like.

How to choose for your firm

• Under 50 people, mostly domestic: Navan Business for booking, plus a planning step for estimates. The software cost is close to zero and custom fields cover client codes.
• 50 to 300 people, heavy rebilling: ITILITE, because the flat $10 fee is easy to pass through and project mapping is built in.
• Long on site work, hotel heavy: Engine for the lodging and Direct Bill, or Perk Starter if you also travel in Europe.
• Several entities, SAP or Oracle ledger, a travel management company: SAP Concur, budgeted as an implementation project.

Frequently asked questions

What is the best corporate travel platform for consulting and professional services firms?

For most US consulting firms under 300 employees, Navan Business or ITILITE. Navan costs $0 for booking and captures client codes in custom fields at checkout. ITILITE costs $10 per trip and maps trips to projects with approvals routed by project code. Large firms on an SAP ledger with a travel management company usually stay on SAP Concur.

How do consulting firms bill travel back to clients?

They tag each booking and expense with a client or project code, export the coded costs to the billing system, and add them to the client invoice at cost, at a capped percentage of fees or at a per diem, as the engagement letter specifies. Capturing the code at booking rather than on the expense report is what keeps trips from going unbilled.

Can contractors bill above the GSA per diem rate?

Not on federal cost reimbursement work. FAR 31.205-46 makes contractor lodging, meal and incidental costs allowable only up to the Federal Travel Regulation maximum per diem, so the excess is unallowable and comes out of the firm's margin. The FY 2027 standard rate, effective October 1, 2026, is $113 for lodging and $68 for meals and incidentals.

Do consulting firms need a travel management company?

Usually not below a few hundred travelers. Self serve platforms like Navan, ITILITE and Perk include 24/7 support for changes. A travel management company earns its fee on complex international itineraries, executive travel and negotiated airline contracts, which is why large consultancies keep one alongside Concur.
