• Personal-credit underwriting and personal liability
• Intro APR is short and purchases-only; 5% BT fee with no 0% BT
• No transfer partners, lounge, or TSA credits; 1.5% trails 2% flats without PRFB

Blue Business℠ Plus Credit Card

Cons

• 2.7% foreign transaction fee
• Public welcome bonus is modest versus premium Amex business cards (15k / $3k / 3 mo on compare pages)

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.

Blue Business℠ Plus Credit Card

This is the Membership Rewards twin of Blue Business Cash — same chassis, same $50k cap, same 0% intro, not cash back and not Business Gold. Confirm the live apply-flow welcome (15k standard vs targeted 25k–75k). Poor daily driver for uncapped high spend, foreign spend, or anyone who will revolve after the intro period.
