  • 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

  • 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

  • 12-month 0% intro APR on purchases

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.

Blue Business Cash® Card

The Blue Business Cash Card is Amex's no-fee workhorse for modest spenders — 2% automatic cash back up to $50k, then 1%, paired with a 12-month 0% intro APR and Expanded Buying Power. It beats uncapped 1.5% cards on the first $50k but loses incremental dollars to Spark Cash Plus or Ink Unlimited above that cap. Best for domestic sole props and small firms who won't chase category bonuses or transfer partners.
