Pros & Cons

Ink Business Unlimited® Credit Card

Pros

• $0 annual fee on primary and employee cards
• Uncapped 1.5% on eligible purchases — simple flat-rate earn
• 12-month 0% intro APR on purchases
• Elevated $1,000 / $8,000 / 4-month welcome bonus (as of 9/3/2026); AU spend counts
• Primary business-use rental CDW up to $60,000 on a no-fee card

Cons

• 3% foreign-transaction fee
• No native bonus categories — loses to 2% flats and Ink Cash/Preferred in bonus buckets
• Personal guarantee + hard personal pull + unofficial 5/24 rule
• Welcome bonus blocked if you ever held this or another $0-AF Chase business card
• No balance-transfer intro APR; no cell-phone protection or premium travel credits

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

Verdict

Ink Business Unlimited® Credit Card

One of the strongest no-annual-fee business cards for flat-rate earn. The Ink Business Unlimited combines uncapped 1.5% cash back, a generous intro APR window, free employee cards, and a elevated welcome bonus — all without an annual fee. Best for domestic spenders who don't need category bonuses or premium travel perks. Poor fit for foreign spend, no-PG seekers, or businesses that would earn more with Ink Cash or Ink Preferred in their bonus categories.

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.
