Verdict

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.

The Business Platinum Card® from American Express

Business Platinum is the lounge-and-credits SKU — not consumer Platinum (different credits, broader direct-airline 5X) and not Business Gold (lower fee, auto-4X ads/restaurants/gas). It pays when portal travel, 2X categories, and enrollment credits are real spend you already have. Unused credits make $895 a net loss versus Ink Preferred or a 2% cash card. Poor daily driver for flat cash back, 0% capital, no-PG underwriting, or flights ticketed direct with airlines.
