Pros & Cons

Engine X

Pros

• $0 annual fee and $0 employee/virtual-card fees
• 6% (scaling to 10%) Engine points on Engine hotel and rental-car bookings — unusual on-platform travel earn at $0 fee
• No personal guarantee and no hard personal credit pull (official apply language)
• Charge card + Autopay + spend controls + unlimited cards for employees and 1099s; travel booking, policy, and folios in one dashboard
• $0 foreign-transaction fee in the fee table

Cons

• Elevated earn does not apply to flights or off-Engine hotels; marketing “up to 10% on travel” is broader than the legal category
• Pay-in-full charge card; $40 late / $40 returned-payment fees; no revolver
• Points have no cash value; official ¢/point not published; statement-credit value may haircut vs booking (secondary)
• Sole proprietors ineligible; U.S. entity + EIN required
• No published lounge, TSA/Global Entry, or card-insurance benefits guide; product is new (Mar 2026) so limit ranges and servicing quality are thinly documented

Blue Business℠ Plus Credit Card

Pros

• $0 annual fee and $0 employee-card fees
• 2X Membership Rewards on the first $50,000 eligible purchases each calendar year with no category tracking
• AmexTravel.com 2X that does not consume the $50k cap
• 0% intro APR on purchases for 12 months
• Points sit in Membership Rewards and can transfer to airline/hotel partners; purchase protection and extended warranty listed on the official benefits block

Cons

• 2X layer caps at $50,000 per calendar year, then 1X
• 2.7% foreign transaction fee
• Public welcome bonus is modest versus premium Amex business cards (15k / $3k / 3 mo on compare pages)
• Joint-and-several personal liability
• No lounge, GE/TSA, trip-cancellation, or cell-phone benefits on the official list; post-intro APR band is high (16.74%–28.49% variable)

Verdict

Engine X

Engine X is a TMC + charge card, not Direct Bill and not Ramp/Brex. Most SMBs stay Silver (6% / 1.5%). Skip it if travel will not move onto Engine, if you need revolving credit or transferable miles, or if you are a sole prop. Confirm the live 20,000-point offer (through 31 Dec 2026) requires $2,000 off-Engine spend within 30 days of first card activation.

Blue Business℠ Plus Credit Card

This is the Membership Rewards twin of Blue Business Cash — same chassis, same $50k cap, same 0% intro, not cash back and not Business Gold. Confirm the live apply-flow welcome (15k standard vs targeted 25k–75k). Poor daily driver for uncapped high spend, foreign spend, or anyone who will revolve after the intro period.
