The biggest threat to procurement’s control over travel and expense isn’t employee defiance it’s the friction baked into legacy T&E policies and tools. When booking experiences feel cumbersome, slow, or overly restrictive, employees bypass approved channels and turn to consumer apps, driving off platform spend and eroding real-time visibility. That leakage weakens vendor negotiating power, complicates compliance, and forces procurement into retroactive, manual clean-up instead of strategic cost management.
