American Express Blue Business Cash

4.5

Amex Blue Business Cash offers 4% on U.S. supermarkets (first $50k/year), 1% thereafter, 4% on gas, 4% on internet/cable/phone, and 1% elsewhere. No annual fee makes it solid for office supply heavy businesses.

The Bottom Line

Amex Blue Business Cash targets specific business expense categories. The 4% on internet, cable, phone, gas, and supermarkets is strong, but the caps ($50k on supermarkets, $25k on gas) limit very high-spend businesses. For small operations with moderate business expenses, it's excellent; for large corporations, cap limitations are frustrating.

4% on Key Business Expenses

The 4% cash back on internet, cable, and phone is valuable for any business paying these essential services. A business spending $200/month on these services ($2,400 annually) earns $96 annually at 4% rateโ€”significant for office overhead. Combined with 4% on gas, a business with multiple drivers or delivery services accumulates substantial rewards.

Frequently Asked Questions

How do the spending caps work?
You earn 4% cash back on U.S. supermarket purchases up to $50,000 annually ($2,000 in rewards), then 1% after. Gas has a $25,000 cap ($1,000 in rewards). Internet/cable/phone has no cap. Caps ensure very high-spend businesses don't earn unlimited bonuses.
Is this better than Chase Ink Business Cash?
Different focus. Ink Business Cash: rotating 5% categories (quarterly activation), 2% dining/travel, no caps. Blue Business: flat 4% on specific categories, caps apply. Choose Ink Business Cash for flexibility and higher maximums; choose Blue Business for predictable internet/gas/supermarket spending.
Does this card have business perks?
Limited perks. It's primarily a cash back card. For business-specific perks (employee cards, account management, etc.), premium business cards offer more.
