Chase Ink Business Unlimited vs Amex Blue Business Cash: Which Is Better?
Two $0-fee flat-rate cash-back cards — one pays more per dollar, the other has no ceiling on how much you can earn. Six rounds. Real numbers. One honest scorecard.
The verdict
Chase Ink Business Unlimited takes it, 3–1 on rounds.
There's no universal winner — Blue Business Cash pays more per dollar up to $50,000, Ink Unlimited never caps at all, so do the math on your actual annual spend before you decide.
Choose Chase Ink Business Unlimited if…
- • Your business spends well over $50,000 a year on the card
- • You want the bigger welcome bonus and an upgrade path for your points
Choose American Express Blue Business Cash if…
- • Your annual spend on the card stays under $50,000
- • You want the higher flat rate with fully automatic, zero-tracking redemption
