A business credit card is basically a usual credit card with a revolving line of credit, but it's specifically designed for business owners and offers benefits, tools and services suited to businesses. Business owners can use a business credit card, repay and use it again.
Best business credit cards typically come with higher credit limits, greater rewards for businesses, tools to help you manage spending, and employee cards. Some cards will require you to pay the balance in full every month - business charge cards, the others will allow you to pay over time, like traditional credit cards.
Large businesses owners, sole proprietors, limited liability companies, freelancers, corporations, startups, small business owners, and anyone in-between can be eligible for a business credit card. You don't have to have employees or/and office to qualify. In some cases, you are not even required to provide an Employer Identification Number (EIN) to apply for a business credit card.
