Pros & Cons

Blue Business Cash® Card

Pros

• $0 annual fee on primary and up to 99 Employee Cards
• 2% automatic cash back on first $50,000 calendar-year eligible spend
• 12-month 0% intro APR on purchases
• Expanded Buying Power — no overlimit fee; rewards earn above limit if approved
• Purchase Protection and Extended Warranty included

Cons

• 2% earn ends at $50k; incremental spend drops to 1%
• 2.7% foreign transaction fee
• Joint-and-several personal liability of Basic Card Member
• Modest standard welcome bonus ($250 / $3k / 3 months) vs many competitors
• Over-limit balances due in full; missed Closing Date can trigger Penalty APR on entire balance

Delta SkyMiles® Gold Business American Express Card

Pros

• $0 year-1 fee then $150 — lowest annual fee in the Delta business lineup
• 1st checked bag free worldwide + 2nd bag free domestic (2026 add) can offset the AF in a few team trips
• 2X on uncapped restaurants plus capped U.S. shipping and U.S. digital/TV/radio ads
• $0 foreign-transaction fee and $0 employee cards (employee spend feeds the $10k flight-credit threshold)
• TakeOff 15 reduces Delta-metal award cost 15%

Cons

• Ongoing $150 AF with credits that are conditional, portal-locked, or enrollment-gated after renewal
• Miles are Delta-only — no Membership Rewards transfers
• No lounge, no GE/PreCheck credit, thinner insurance than Platinum/Reserve Business
• No 0% intro APR; carrying a balance is expensive (19.49%–28.49% as of 09/02/2026)
• Personal guarantee / joint and several liability; advertising 2X is MCC-narrow (media providers, not any marketing vendor)

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.

Delta SkyMiles® Gold Business American Express Card

This is the low-fee Delta business cobrand — not personal Delta Gold (supermarkets 2X), not Platinum/Reserve Business, and not Amex Business Gold (MR). Confirm the live apply-flow welcome (90k/$6k through 11/4/2026 on Delta vs 60k/$4k still on Amex’s product URL). Skip it if you will not fly Delta, want transferable points, need 0% float, or refuse a PG.
