Engine combines travel booking, expense management and rewards into a single platform, serving more than 30,000 businesses. Engine X is the company’s business charge card offering, designed specifically to let those companies earn additional rewards on travel spending while maintaining oversight and control over employee expenses. The card addresses a common friction point for growing organizations: how to give employees the tools to travel when needed while ensuring the company can track, manage and ultimately reduce those costs.
The Business Problem Engine X Solves
Business travel is often one of the largest categories of spending for any organization with employees who move between locations or travel to client meetings and events. Between flights, hotels, rental cars and incidental expenses on the road, the costs accumulate quickly across an organization. Most businesses already issue corporate cards to employees for these expenses, but many of those solutions lack integration between the booking process, the expense tracking and the rewards generation.
Engine X approaches the problem differently by combining all three into one platform. The card is built directly into Engine’s existing travel booking and expense management system, so rewards generation happens automatically as part of the same workflow where employees book travel and the company manages expenses.

Welcome Bonus and Card Basics
New Engine X cardholders can earn 20,000 Engine points after activating the card and spending $2,000 in qualifying off-platform purchases within 30 days of approval. Points are enrolled automatically in Engine’s loyalty program upon card activation.
The card carries no annual fee, no rewards cap, and no personal credit check or personal guarantee requirement. The application takes approximately 15 minutes to complete, and most eligible businesses receive a decision within 24 hours. Engine X is issued by Fifth Third Bank N.A.
Earning Rates Across Purchase Categories
Travel Booked Through Engine’s Platform
The highest earning rates apply to travel booked through Engine itself. Cardholders earn 6% back in points when booking hotels and rental cars through the platform. As annual spending increases, the earning rate escalates: 7%, then 8%, and ultimately 10%. This tiered structure rewards organizations that consolidate their travel spending through a single platform.
Other Business Expenses and Flights
Flights booked outside the Engine platform, along with most other eligible business purchases, earn 1.5% back in points. This flat rate applies to everyday expenses incurred while traveling: meals, ground transportation, office supplies, and other business costs that employees cover with the card.
No Limits on Accumulation
Unlike some corporate rewards programs that impose earning caps after a certain threshold, Engine X has no ceiling on points accumulation. Businesses can use the card for all employee spending without any reduction in earning rates due to volume or timing.
Stacking Multiple Rewards on Hotel Reservations
One of Engine X’s most distinctive features is the ability to layer multiple rewards sources onto a single hotel booking. When a cardholder reserves an eligible hotel through Engine, the booking can simultaneously include:
- A discounted room rate negotiated by Engine
- Hotel loyalty program benefits earned through the cardholder’s hotel membership
- Engine Rewards points for the booking itself
This structure matters because many third-party travel platforms force a choice: accept a lower price by forfeiting hotel loyalty benefits, or keep the loyalty benefits and pay full retail. Engine’s design preserves both, creating additional value for organizations whose employees stay at the same hotel chains repeatedly and can accumulate meaningful loyalty status.
How Points Are Redeemed
Engine Rewards points can be redeemed toward any travel booked through the platform—flights, hotels, rental cars—at full value. Alternatively, points can be converted to a statement credit, though the credit value is 50% of the travel redemption value. For example, points worth $100 toward travel are worth $50 as a statement credit. Most businesses that prioritize reducing travel spend use the travel redemption option.
Flexibility in How Rewards Are Distributed
Engine provides administrators with multiple options for how earned rewards flow. Rewards can remain under the company’s control and be applied toward future travel expenses. Alternatively, rewards can flow directly to individual employees for their personal travel bookings, creating a direct incentive for employees to use the platform. Companies can also gift points to employees as recognition or performance incentives outside the normal earning structure.
This distribution flexibility can affect employee engagement, particularly in organizations where frequent travel is routine and workers value the ability to earn something tangible from those trips.
Spending Controls and Real-Time Expense Visibility
Effective business travel management requires balancing employee autonomy with financial oversight. Engine X provides several tools that make this balance easier to maintain.
Issuing and Managing Cards
Administrators can issue virtual card numbers immediately for online bookings. Physical cards are available when employees need them for in-person transactions. Each card can be configured with spending controls specific to individual employees, merchants, spending categories, or transaction limits. This granularity allows the same card to be used across a team while enforcing different rules for different employees based on their roles or anticipated spending.
Real-Time Expense Tracking
Finance teams gain visibility into company spending as transactions occur, rather than waiting until the end of a billing cycle or relying on employees to submit expense reports. This real-time information enables faster spending decisions and quicker identification of unusual or potentially policy-violating transactions.
For organizations with field employees or frequent travelers, these features reduce manual expense reconciliation while maintaining the controls necessary to prevent unauthorized or off-policy spending.
Application Requirements and Approval Timeline
Engine X is accessible to businesses of many sizes. Unlike many traditional business cards, the application does not require applicants to undergo a personal credit check. There is no requirement for a personal guarantee. The application itself takes approximately 15 minutes to complete, and most eligible businesses receive a final decision within 24 hours.
This streamlined process means businesses can get approved and issue cards to employees quickly, with minimal bureaucratic friction compared to traditional corporate charge card applications.
Best Fit for Your Organization
Engine X is most likely to deliver value for small to midsize businesses with regular employee travel. Organizations that benefit most from the card typically have:
- Employees who travel multiple times per year for business purposes
- Regular bookings across hotels, rental cars, and flights
- A preference for centralized visibility into travel spending
If your business currently books frequent hotel stays, rental cars, and flights for employees and lacks integrated visibility into that spending, Engine X addresses both the rewards opportunity and the management problem.
The 20,000-point welcome bonus is available for a limited time.
