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

Spark Cash Plus

Pros

• Uncapped 2% cash back on all net purchases
• NPSL capacity plus free employee and virtual cards
• $150 annual fee refunded at $150,000 net spend by anniversary
• Large year-1 bonuses — $2,000 at $30k/3 mo plus $2,000 per $500k spent
• $0 foreign transaction fee; 5% on Capital One Business Travel hotels/VR/cars

Cons

• $150 fee is real if spend stays below $150k/year
• Pay-in-full design — 2.99% late fee and Pay Over Time interest if you carry
• Bonus hurdles favor very high spenders ($30k/3 mo, $500k increments)
• No 0% intro APR and no balance transfers
• Bonus often blocked for existing/previous Capital One Business cardholders

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.

Spark Cash Plus

Capital One Spark Cash Plus is the go-to for businesses with serious spend who can pay in full. Uncapped 2%, NPSL flexibility, free employee/virtual cards, and a refundable $150 fee at $150k make it a premium flat-rate engine — especially with the live $2,000 welcome bonus and limited $500 travel credit (through Sep 7, 2026). Poor fit for 0% financing seekers, lounge hunters, or businesses under $150k annual card spend.
