About Engine
Engine (formerly Hotel Engine) is a corporate travel and spend management platform that lets companies book hotels, flights and rental cars at pre-negotiated business rates without paying a subscription. It layers travel policies, consolidated DirectBill invoicing, corporate cards, group booking tools and 24/7 live support on top of a network of over one million properties. The platform is free to join because hotels and travel suppliers pay Engine a commission on each booking, with an optional FlexPro subscription for unlimited changes and late cancellations.
Pros & Cons
Pros
- Genuinely free to use with no per-seat licensing, contracts or minimum spend, which is unusual among corporate travel platforms
- Negotiated inventory is the real product: Engine reports a 26% average saving and discounts up to 60% on its 1,000,000+ property network
- DirectBill consolidated invoicing and prepaid incidentals stop employees from fronting hotel costs on personal cards
- Strong fit for non-office travel such as construction crews, field service teams and sports teams, with dedicated group and RoomBlocks flows
- Travelers keep their own hotel loyalty points while the company earns Engine Rewards on the same booking
Key Features
Business-exclusive negotiated rates
Access discounts of up to 60% across 1,000,000+ hotel properties plus flights and rental cars, with a reported 26% average saving versus public rates.
All-in-one booking
Book lodging, air travel and car rentals from a single dashboard instead of stitching together separate suppliers and booking sites.
DirectBill consolidated invoicing
Roll every company charge into one itemized invoice, keep all folios in one place, and cover incidentals in advance so travelers do not front costs.
Travel policies and budget controls
Set per-trip, per-team or per-project spend limits, enforce custom travel policies at booking time, and track spend by job or cost center.
Corporate cards and spend controls
Issue virtual and physical cards instantly with per-card limits, extending the platform from travel booking into broader spend management.
Group and crew booking
Purpose-built flows for construction crews, sports teams, conferences, offsites and disaster relief, including RoomBlocks for reserving blocks of rooms.

Best For
Crew and field workforce lodging

Event teams, sports programs and conference organizers reserve room blocks and coordinate dozens of travelers without negotiating contracts hotel by hotel.
Cutting hotel spend without a TMC
Small and mid-sized companies with no travel manager get corporate-rate access and policy enforcement without paying agency fees or signing a travel management contract.
Controlling unpredictable travel
Teams whose schedules shift constantly use FlexPro to book cheaper non-refundable rates while keeping the ability to cancel or shorten stays.
