Small businesses can benefit from opening business credit cards to keep personal and professional expenses separate and streamline spending. These cards come in various shapes and sizes, offering rewards, interest-free financing, luxurious travel perks, extended warranties, insurance, and more. To get approved for a business card, excellent credit is typically required, but there are options for business owners with less than stellar credit. CNBC Select reviewed dozens of popular business cards and chose the best value overall in eight main categories: cash back, travel, no annual fee, welcome bonus, luxury, special financing, average credit, and shipping. The Capital One Spark Cash Plus, Ink Business Preferred Credit Card, Chase Ink Business Unlimited, and American Express Business Platinum Card provide various cash-back rates, rewards, and premium perks for business owners.
