The short version

  • Only Kayak has a free tier, so it costs nothing to try first.
  • Each has a real cost: Center the product is built around its own card, so employees still using a legacy bank corporate card get the ordinary receipt-chasing experience and the real-time promise does not apply to them.; Kayak it is owned by Booking Holdings, the same parent as Booking.com and Priceline, so its comparison results are not fully independent of its own group's commercial interests.
  • They diverge on capability: Center covers Center corporate card, Kayak covers Flight, hotel and car comparison.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Center

  • The product is built around its own card, so employees still using a legacy bank corporate card get the ordinary receipt-chasing experience and the real-time promise does not apply to them.
  • Travel booking depends on Spotnana, meaning content, service levels and roadmap for a core part of the product sit with a third party Center does not control.
  • It is a United States product, and multi-entity companies with European or Asian subsidiaries will need a separate card and expense stack for those entities.
  • Interchange on card spend is a significant part of how the vendor earns, which is why the software price looks low; a company that keeps most spend on an existing card programme is a poor fit commercially.
  • It is a smaller supplier than Brex, Ramp or SAP Concur, so integration coverage outside the main US accounting systems is thinner and custom connectors are often the answer.

Kayak

  • It is owned by Booking Holdings, the same parent as Booking.com and Priceline, so its comparison results are not fully independent of its own group's commercial interests.
  • Some airlines opt out of listing on metasearch sites entirely, so Kayak's results are not a complete view of every available fare in the market.
  • Revenue comes from referral commissions, and prominence in results can be influenced by which suppliers pay Kayak more, not purely by lowest price.
  • The actual booking typically completes on a third party site, so problems with a booking, cancellation or refund are handled by that site's customer service, not Kayak's.
  • Displayed prices can change or fail to match by the time a user reaches the booking site, since Kayak is not always querying live inventory in real time for every listed fare.

Answered from the vendors’ own pages

Center: Do we have to use the Center card?

Effectively yes for the core benefit. Center can ingest other card feeds, but real-time capture, controls and the pricing model all assume its own card.

Kayak: Does Kayak charge a booking fee?

No, Kayak itself is free to use; it earns referral commissions from the airlines, hotels and sites it sends bookings to.

Center: Who provides the travel booking?

Spotnana provides the underlying Travel-as-a-Service platform; Center provides the interface, policy layer and reporting.

Kayak: Do I book directly through Kayak?

Usually the booking completes on the airline, hotel or travel site's own platform after Kayak hands off the click, though some direct booking options exist for select content.

Center: Is there a per-user licence fee?

Center markets usage-based pricing with no licence, deployment or support fees; the economics rest on card interchange and booking fees.

Kayak: Is Kayak owned by an airline or hotel chain?

No, it is owned by Booking Holdings, which also owns Booking.com, Priceline and Agoda.
