A vendor, such as an airline, hotel chain, car rental company, or ground transportation provider, that a company selects for a formal, negotiated travel partnership in exchange for a guaranteed share of its travel spend.
A preferred supplier is a vendor, such as an airline, hotel chain, or car rental company, that a company selects for a formal travel partnership after negotiating rates and service terms. Travel programs steer bookings toward these vendors through policy rules and booking tool defaults, trading a guaranteed share of travel spend for lower prices and service guarantees.
The GBTA and ALTOUR 2025 State of Corporate Travel Policies study found that booking outside required channels is the single largest travel policy compliance issue, cited by 35% of travel managers, ahead of payment, air, and meal compliance combined [1].
The same study found that 28% of travel managers cite out-of-policy hotel stays as a major compliance challenge, the second most common issue after booking channel itself [1].
Navan ranks preferred suppliers first in search results and applies negotiated rates and loyalty numbers automatically at the point of booking, so travelers do not need to check a separate vendor list before they book.
Preferred supplier contracts typically bundle a rate discount with room-night or seat commitments, defined service-level agreements, and regular spend reporting back to the travel team.
What is a Preferred Supplier?
A preferred supplier is a vendor, such as an airline, hotel chain, car rental company, or ground transportation provider, that a company or its travel management company (TMC) selects for a formal, negotiated partnership. In exchange for directing a guaranteed volume of bookings to that vendor, the company secures discounted rates, service guarantees, and perks like room upgrades or flexible cancellation terms.
The arrangement realigns incentives on both sides. A company that can commit to 500 room nights a year with one hotel group negotiates a better rate than one requesting a single booking, and the supplier gains predictable revenue it can plan capacity around. Travel managers typically maintain a preferred supplier list by category (airline, hotel, car rental, ground transportation) and configure the travel policy and booking tool to surface those vendors first.
Selecting a preferred supplier starts with a review of travel spend and destination patterns, then moves into a formal request for proposal (RFP). Vendors submit bids covering pricing, service capabilities, safety standards, and inventory availability, and the travel team scores each bid against the company's actual booking patterns rather than a generic price comparison.
Contract terms typically bundle several commitments beyond a discount percentage: room-night or seat volume commitments, service-level agreements for disruption response, regular spend and compliance reporting, and reduced or waived cancellation fees compared to public rates.
Not every vendor relationship carries the same weight, and confusing the tiers below is a common planning mistake:
Supplier Tier
Negotiated Rate
Booking Tool Priority
Volume Commitment
Preferred
Yes
Surfaced first
Yes, contractual
Approved
No
Neutral placement
No
Sole-source
Yes, exclusive
Only option shown
Full category volume
A preferred supplier earns priority placement through a negotiated deal. An approved supplier simply meets the company's safety and policy standards without a rate agreement. A sole-source supplier is the only vendor used in a category, typically under an exclusive contract that removes traveler choice entirely.
Why Employees Still Book Outside Preferred Suppliers
Preferred supplier programs only work when travelers actually use them, and channel leakage remains the top travel policy compliance issue that travel managers report today [1]. Three factors explain most of it.
Personal loyalty status. A frequent flyer with elite status on one airline often keeps booking that carrier even when a preferred competitor shows a lower fare, because losing status feels like a bigger loss than the price difference.
Unclear communication. Many travelers have no idea their company maintains a preferred supplier list at all. The rules live in a policy document most employees have never opened, so they book the vendor with the best schedule instead of the one carrying a corporate rate.
Booking tool friction. When a corporate booking tool takes more clicks or shows fewer options than a consumer site, travelers work around it instead of through it.
None of these three factors respond well to stricter enforcement alone. Programs that surface preferred options automatically, apply loyalty numbers without manual entry, and explain the savings travelers help protect see meaningfully higher voluntary travel policy compliance than programs that rely on policy documents alone.
Best Practices for Managing a Preferred Supplier Program
Programs that earn strong voluntary compliance share a few habits.
Default the booking tool to preferred options. Ranking negotiated suppliers first, rather than requiring travelers to filter for them, removes the extra step that causes people to book the first reasonable option instead. This single configuration change often delivers a bigger compliance improvement than any policy memo.
Measure voluntary compliance, not just contract signatures. A signed agreement with a hotel group means nothing if travelers keep booking elsewhere. Track the share of bookings that actually use preferred suppliers by category, and treat a declining trend as an early warning that the program needs better communication or better tools, not a policy reminder.
Revisit contracts as travel patterns shift. A preferred supplier list built around old destination patterns may no longer match where the company travels today. Reviewing travel policy and vendor performance on a regular schedule catches mismatches before they erode negotiated value.
When Should You Consider Alternatives to a Formal Preferred Supplier Program?
A dedicated preferred supplier program is not the right investment for every company, and recognizing when it is not avoids sinking negotiation time into contracts that will not pay off.
Low or unpredictable travel volume. Negotiating volume-based discounts only works when a company can credibly promise consistent bookings. A company with fewer than a few hundred trips a year rarely has enough volume to negotiate meaningful discounts, and the time spent negotiating can exceed the savings.
Highly decentralized travel patterns. Organizations where employees travel to dozens of scattered destinations with no repeat pattern struggle to concentrate enough volume in any one market to matter to a supplier.
Early-stage travel programs. Companies just beginning to manage travel formally often get more value from working with a travel management company that already holds negotiated rates across its full client base, rather than building supplier relationships from scratch.
As travel volume grows and destination patterns stabilize, most companies eventually build a formal preferred supplier list. The right time to start is when procurement can point to at least one destination or vendor category where the company's booking volume is large enough to negotiate real terms, not just request them.

Frequently Asked Questions About Preferred Supplier
A preferred supplier is an airline, hotel chain, car rental company, or other vendor that a business selects for a formal, negotiated partnership. In exchange for a guaranteed share of the company's travel spend, the supplier offers discounted rates, service guarantees, and perks such as priority upgrades or waived cancellation fees.
A preferred supplier has a negotiated rate and is actively prioritized in booking tool search results. An approved supplier meets a company's safety and policy standards but carries no negotiated discount. Travel teams sometimes confuse the two, which leads them to expect volume-based savings from vendors that were only ever baseline-approved.
Most negotiations start with a request for proposal based on the company's actual travel spend and destinations. Vendors submit bids covering pricing, service capabilities, and safety standards. Contracts typically bundle a rate discount with room-night or seat commitments, defined service-level agreements for disruptions, and regular spend reporting back to the travel team.
Navan lets travel managers configure preferred suppliers by category and automatically ranks those vendors first in search results, applying negotiated rates and loyalty numbers at the point of booking. This removes the extra step of manually checking a vendor list, which is one of the most common reasons preferred supplier compliance slips.
Three factors drive most leakage: personal loyalty status with a non-preferred airline or hotel, unclear communication about which vendors are actually preferred, and booking tools that show fewer options than consumer sites. None of these responds well to enforcement alone. Programs that fix the underlying friction see stronger voluntary compliance.
Yes, but negotiating real discounts usually requires consistent volume, typically at least a few hundred trips a year to one destination or vendor category. Companies below that threshold often get better value working with a travel management company, or a platform like Navan that surfaces negotiated rates automatically, rather than negotiating supplier contracts from scratch.
