What's the difference between a line of credit and a business credit card?

A line of credit works similarly to a business credit card—you withdraw funds whenever necessary and only pay interest on what you use. However, credit cards are often unsecured, whereas with a line of credit, you have the option to go for a secured loan. As a result, interest is likely to be lower, and you may end up being able to borrow more money than with a credit card.
