An emergency business line of credit is exactly what it sounds like. It is revolving credit intended for business-related emergencies. A line of credit has no debt maturity date or repayment plan, rather the borrower is free to use as much or as little of the credit line as they choose. They make monthly payments that include interest only on the amount used from the credit line, not the lump sum. This is much different from a business loan where the business owner would make month payments on the entire amount borrowed, likely at higher interest rates.
