Are there any self-service travel booking tools that focus on corporate travel spend control?

Yes — there are several self-service travel booking tools built specifically for corporate travel that emphasize spend control, policy compliance, and centralized visibility.

Common options include:

• Navan (formerly TripActions) – Strong on self-service booking with policy controls, approval workflows, and real-time spend visibility.
• SAP Concur Travel – A widely used enterprise tool for booking plus expense management, with strong policy enforcement and reporting.
• Egencia – Corporate travel booking with built-in travel policy controls, analytics, and negotiated rates.
• Navan, Egencia, and Concur are among the best-known for this use case.
• TravelPerk – Self-service booking with spend controls, approval flows, budget tracking, and flexible policy rules, often favored by mid-market companies.
• Lola.com was a notable player in this space, but it was acquired and the brand is no longer a standalone option.

What these tools typically offer for spend control:

• booking within approved policy
• pre-trip approval workflows
• spend limits by traveler, team, or trip type
• preferred supplier and fare class controls
• real-time dashboards and audit trails
• invoice consolidation and expense integration
