Verdict

Business Advantage Unlimited Cash Rewards

Unlimited is the simple SKU in the Business Advantage cash pair — 1.5% with no cap, or up to 2.62% if Preferred Rewards for Business Platinum Honors is real for you. It is not Customized (3%/2%/1% with a $50k cap). Without PRFB it is a fine no-fee 1.5% card that loses to Ink Unlimited's bonus and Spark Select's longer 0% window. With PRFB it becomes one of the better uncapped cash rates in the set. Skip it for foreign spend or no-PG underwriting.

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.
