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.

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.
