A business line of credit is quite similar to personal lines of credit. The financial institution grants access to a specific amount of financing. However, no interest is incurred until the funds are tapped into. A business line of credit can be unsecured or secured (typically, by inventory, receivables or other collateral). Lines of credit are often referred to as revolving and can be tapped into repeatedly. For instance, if there is access to a $60,000 line of credit and $30,000 is taken out, access to the remaining $30,000, if necessary, remains. If all $30,000 is paid back, there is access to the entire $60,000 without having to reapply, one of the biggest benefits of a line of credit.
