Small business credit cards typically offer lower interest rates, higher credit limits, and more flexible terms compared to corporate cards. When it comes to rewards, small business credit card holders earn them personally, while corporate card rewards are earned by the business. With a small business credit card, the primary cardholder is responsible for any debt and fees incurred, while with a corporate card, the company is responsible for all expenses. Additionally, corporate cards require the balance to be paid in full each month, while small business credit cards allow carrying a balance.
