Procurement cost savings: 8 strategies for T&E

Procurement cost savings in corporate travel and expense (T&E) depend in part on how much of the program’s spend receives the rate a buyer negotiates. A discounted hotel contract, for example, delivers no savings if employees book rooms somewhere else. The same coverage issue applies to spend outside the employee program, such as interview trips recruiters book for job candidates, which a guest travel tool can bring under the same policy and reporting.

In other words, negotiated savings become realized savings as more spend comes under the program, so each strategy below starts from the same foundation: accurate spend visibility.

Consolidate the spend and the data before you negotiate

Hard savings reduce spend against an established baseline; cost avoidance measures a future increase that procurement prevented or reduced. Procurement savings in T&E start with a single view of what the company spends, because volume that lives in three systems may be hard to present to a supplier as a single number. Cost pressure makes that view urgent.

And cost management is a high priority. In fact, in Deloitte’s Q1 2026 CFO Signals survey, 52% of 200 North American CFOs at companies with at least $1 billion in revenue named cost management as their top internal concern, up from 47% six months earlier. Across procurement more broadly, digital maturity tracks with results. Deloitte’s 2025 Global Chief Procurement Officer Survey found that 96% of the procurement teams it classifies as Digital Masters met or exceeded their cost savings plan, compared with 80% of follower organizations. That makes a unified view of spend a practical place to start.

In T&E, consolidation can produce savings before a single rate changes. The first three strategies below show how.

1. Centralize fragmented T&E onto one system

Moving booking, expense reporting, and corporate cards onto one system gives you a single data model to negotiate from. A vendor consolidation strategy for T&E also treats those tools as one category and sources them together. Recruiting and candidate travel belong in the consolidation as well. Navan Guest Travel is one option that brings candidate travel under the same spend controls and visibility.

And most buyers want to consolidate. The State of Corporate Travel and Expense 2026, a report from Skift and Navan, found that 77% of the T&E managers surveyed said they want an all-in-one T&E system, up from 66% two years before.

2. Build a spend cube before the next RFP

A spend cube is a multidimensional data model that organizes purchasing data by supplier, spend category, and business unit, which gives procurement a credible baseline for discussions with hotel and airline sales teams. In T&E, booking, card, and expense records can all contribute to the spend cube, which makes consolidated data important.

Before you open a request for proposal (RFP), the cube should answer questions such as:

• Which properties and carriers took the most spend, by city and by quarter?
• What share of room nights landed at contracted properties versus non-preferred ones?
• Which departments or individuals book outside the program most often?
• How much recruiting and candidate travel is booked outside the program, and by whom?
• How far did the rates paid drift from the rates negotiated?

Each answer helps turn a general ask into a specific one, such as a rate for a named property or a share target for a city. For example, the contracted-property share can be compared with an external benchmark. In GBTA and Radisson Hotel Group’s The Evolution of Managed Hotel Programs, travel managers reported that nearly 57% of hotel bookings occur at hotels with company-negotiated rates. Once you know how much spend reaches negotiated properties, use that baseline to evaluate renewals alongside market expectations.

Use your baseline to evaluate renewals alongside market expectations. On the market side, Business Travel News’ 2025 hotel survey found that most respondents expected corporate hotel rates to increase in 2026, although only 24% expected increases above 5%. If market rates would otherwise have increased, a flat renewal may represent cost avoidance.

3. Rationalize the supplier panel

Supplier consolidation works in T&E when the panel reflects where your travelers go and gives each supplier more volume. Rank properties and carriers by spend share and traveler demand in each city, then keep the ones that cover your top destinations.

A supplier panel review also needs to account for inventory breadth. Navan Travel addresses this by combining global distribution system (GDS) connections, New Distribution Capability (NDC) connections, and online travel agency (OTA) partnerships to help surface competitive rates. Navan’s Lodging Collection provides businesses of all sizes access to corporate-level discounts, including loyalty benefits — a designation marked on the hotel search results page.

Keep negotiated rates available

A negotiated rate has to load correctly and appear in the traveler’s search before it can deliver savings, and its value still depends on how it compares with available market rates. Skift’s August 2026 reporting on one hotel group’s corporate rate tools noted that the negotiated rate frequently wasn’t visible when the traveler would go to book — something the group is fixing. The discount can be lost at any step between contract and checkout. Strategies 4 through 6 cover how to keep it visible.

4. Verify loaded rates on a regular schedule

Compare the contracted rate with the loaded rate on a regular schedule. Without that comparison, a rate that's never loaded can stay in place unnoticed. Yet in the same GBTA and Radisson survey, respondents reported that only 39% of travel programs audit their travel management company (TMC) or online booking tool multiple times a year with strong oversight in place.

Skift’s reporting on that hotel group noted that its rate-auditing tools automatically triage whether a shortfall stems from a loading error, closed availability, or a third-party channel issue. A loading error means the contracted rate never reached the booking system. Closed availability, however, means the hotel didn’t open the loaded rate for booking. The diagnosis helps determine the appropriate party to resolve the issue, though the report does not specify the exact contact or escalation process.

Direct connections can shorten the chain between hotel and booking tool, which gives an audit fewer links to check. On July 7, 2026, Navan and Hilton announced plans for a direct connection that gives Navan real-time access to Hilton’s central reservation system for availability, rates, and booking. With fewer hand-offs, a negotiated rate has fewer opportunities to be lost.

5. Enforce policy inline during search

Travelers choose only among the policy-compliant bookings they see. A booking tool that’s configured with the travel policy filters results based on eligible fare classes and hotel rate caps, then ranks preferred suppliers first. Travel policy can therefore be enforced during search and booking, before the purchase is made. Post-trip review can’t prevent the original purchase; it can merely identify an out-of-policy booking.

That distinction matters because purchases made outside approved policies and contracts can reduce expected savings. The Hackett Group’s 2025 procurement research found that Digital World Class procurement teams had 60% less savings lost to maverick buying and contract noncompliance than their peers.

On the T&E side, a GBTA poll of 571 corporate travel buyers, travel suppliers, and TMC professionals, conducted in January 2026, found that travel buyers cited missing content in the booking tool (46%) and leakage (39%) among their top operational challenges for 2026. Both come down to what the traveler sees at search: If the tool lacks the content or the negotiated rate, the booking can leave the program.

A program has to distinguish bright-line rules from judgment calls. For example, a company might require approval for first class on a domestic route while giving travelers a soft warning when a hotel exceeds the rate cap in a high-demand market. Set rate caps by destination and season, so the soft warnings you review flag real exceptions.

6. Reward travelers for booking under budget

Travelers may have a direct reason to choose cheaper hotels when they share in the savings. In the Skift and Navan survey, 72% of business travelers surveyed said they would book less expensive hotels if offered financial incentives. Navan Rewards gives employees credits toward personal travel when they book business-trip hotels below the policy threshold. This balances cost controls with traveler satisfaction.

Automate the back office to retain savings through close

Savings captured at booking can leak during expense processing — a process that can involve a high volume of repetitive transaction records. But controls at the point of swipe take effect before a charge is even finalized. AI-powered audits can then review those charges that are finalized.

7. Control spend at the point of swipe

When policy rules are attached to a corporate card, the system checks whether a charge is compliant before the receipt exists. Having these spend controls at the point of swipe allows systems to authorize compliant transactions and flag or decline out-of-policy ones, with borderline cases routed to review. Moving the decision to the moment of purchase can leave fewer disputes for the accounting team at close.

Navan Expense applies this model. Its policy system flags or declines out-of-policy transactions at the point of swipe based on expense category and department, along with merchant-level rules. Triggers include weekend spending without an approved trip and card use when there’s no active travel. Each transaction also has 130-plus data points that are captured automatically, including the merchant, cost center, and general ledger (GL) code. This information can also inform the spend cube from strategy 2 without anyone re-keying it.

8. Review every transaction with AI-powered audit

Reviewing the whole ledger helps your team keep pace as AI makes fraudulent receipts and other documents harder to assess. The Journal of Accountancy reported in July 2026 that internal fraud investigators are finding more fake receipts and other documents that employees built with AI tools.

That makes expense fraud detection important, because it can cover every transaction. Navan’s Audit Agent can do that work for your team and surface only the spend that needs attention, including out-of-policy purchases hidden inside compliant-looking expenses. Time savings may be another benefit: A Forrester Consulting Total Economic Impact™ study commissioned by Navan and based on a composite organization projected that finance teams could save 40% of the time spent on expense auditing and reconciliation by switching to Navan.

Procurement savings in T&E start with the spend you can see

Negotiated rates deliver savings when booking, card, and expense records live in one system. With that data in place, controls can act before money moves. Full-ledger review also helps keep processing costs from offsetting the savings.

The later strategies each need a baseline to measure against. That baseline comes from the first two strategies, so programs that must pick one place to start should begin there.
